The top layers are heated by the plastic sheets ability to trap solar radiation in the soil. During the sweltering summer months, Solarization may raise the temperature of the soil to such an extent that it kills nematodes, weed seed, and seedlings, as well as several disease-causing organisms (pathogens). It is simple to utilize on a little or large scale and doesn't leave any harmful residues. In addition to improving soil structure, soil Solarization raises the availability of nitrogen (N) and other vital nutrients for plants. Field, vegetable and flower crops, as well as orchards, vineyards, greenhouses and gardens have all benefited from the straightforward, secure, and efficient process of Solarization. For increased efficacy, it can be used in conjunction with organic soil amendments or at lower pesticide treatment rates. Solarized soil frequently results in significant improvements in plant growth, harvestable output and crop quality, which can last for several growing seasons. In the warmer regions, there is great potential for employing soil Solarization to manage pests and diseases.</p> Ravindra Jadhav, Anurag Kumar Singh, Prasad Margal Copyright (c) 2026 Author(s).

These microscopic soil-borne pests damage root systems, impair nutrient and water absorption, and predispose plants to secondary bacterial and fungal infections, thereby intensifying crop health problems. Traditional PPN management has depended heavily on chemical nematicides; however, their high cost, persistence in the environment, non-target effects and increasing regulatory restrictions have reduced their long-term suitability. Climate change, intensive cropping systems and declining soil biodiversity may further increase nematode pressure in many agroecosystems. Sustainable nematode management therefore requires an ecological and integrated approach. Recent evidence indicates that resistant and tolerant cultivars, crop rotation and diversification, organic amendments, biological control agents and soil-health-based practices can reduce nematode populations while supporting ecosystem services. Emerging tools, including molecular diagnostics, genomics-assisted breeding and precision agriculture, provide opportunities for earlier detection, targeted intervention and improved understanding of nematode-plant-microbe interactions. This review consolidates current challenges associated with plant-parasitic nematodes and outlines future directions for sustainable management strategies that prioritise productivity, environmental safety and long-term soil resilience. Strengthening farmer awareness, policy support and interdisciplinary research will be essential for translating these strategies into practical and scalable solutions for sustainable agriculture.</p> Nilotpal Das, Hasim Kamal Mallick Copyright (c) 2026 Author(s).

These unfavourable soil conditions disrupt nutrient availability, microbial activity, water uptake, and plant physiological processes, ultimately reducing crop growth and yield. Furthermore, prolonged environmental stresses often contribute to diminishing microbial populations, reducing the abundance and activity of beneficial microorganisms involved in nutrient cycling, soil fertility, and plant stress adaptation. Consequently, microbial inoculation has emerged as a promising eco-friendly strategy for restoring soil biological functions and improving agronomic performance under stressful environmental conditions.</p> <p>This review aimed to evaluate the application of beneficial microbes in problematic soils through bibliometric and systematic literature review approaches. Bibliometric analysis using VOSviewer revealed increasing research trends related to rhizosphere microbiology, plant growth-promoting rhizobacteria (PGPR), microbial diversity, diminishing microbial populations, salinity stress, drought stress, and sustainable agriculture. The systematic review demonstrated that beneficial microbes, including PGPR, nitrogen-fixing bacteria, phosphate-solubilizing bacteria, arbuscular mycorrhizal fungi (AMF), and microbial consortia, significantly improve plant growth, nutrient uptake, chlorophyll content, stress tolerance, and crop productivity under various problematic soil conditions. In addition, microbial inoculation enhances soil health through improved nutrient cycling, microbial activity, soil enzyme activities, soil aggregation, and remediation of salinity and heavy metal toxicity. Despite challenges related to field performance variability, limited microbial survival, environmental variability, and insufficient farmer awareness, beneficial microbes remain promising biological agents for supporting sustainable and climate-resilient agricultural systems while reducing dependence on synthetic agricultural inputs.</p> Rizky Surya Triana, Rafi Ali Akbar, Fairus Hisanah Hibatulah, Anne Nurbaity, Tualar Simarmata Copyright (c) 2026 Author(s).

Walp.] in the Far North Region of Cameroon https://journalarja.com/index.php/ARJA/article/view/862 <p><strong>Background: </strong>Cowpea is a protein-rich legume essential for food security in sub-Saharan Africa, but its productivity is increasingly constrained by drought and irregular rainfall patterns.</p> <p><strong>Objective</strong><strong>:</strong> To address intra-seasonal drought episodes when they occur at critical stages of the crop and to mitigate the resulting decline in yield in Cameroon, it is necessary to identify and understand the mechanisms of water-stress tolerance in accessions at different stages of their growth cycle.</p> <p><strong>Methodology</strong><strong>: </strong>One hundred and seventy-three cowpea accessions and one control variety were evaluated under two factors (genotype and developmental stage) for their response to different water conditions. The agro-morphological and physiological parameters of the plants were assessed per bag in a randomized complete block design with three replications. An intermittent water-deficit treatment covering both the vegetative and reproductive stages was studied.</p> <p><strong>Results and Discussion: </strong>The results show that water stress negatively affects agro-morphological and physiological variables, considerably reducing their performance, and that its effect is more noticeable during the second water stress. Nevertheless, water stress caused a greater increase in chlorophyll content in the majority of accessions during the second water stress (SH2), from the vegetative stage to flowering, which led to a decrease in final productivity because of their inability to manage light energy (photoinhibition). Accessions A161, A108, A106, A1 and A151 proved to be accessions of choice in terms of pod production, seed production, root size per plant and water-stress tolerance. Accessions A12, A45, A93, A105, A146 and A167 also proved to be accessions of choice in terms of greenness, recovery rate, chlorophyll content and water-stress tolerance, outperforming the control variety A140 in performance. The identification of these accessions could be used in breeding programs to improve cowpea tolerance at the vegetative and/or reproductive stages and could help increase yield.</p> <p><strong>Conclusion: </strong>Based on yield-related traits, root length and responses to water deficit, the study revealed that accessions A161, A108, A106, A1 and A151 were identified as promising drought-tolerant accessions.</p> Linda Charlotte Kewang Akiki, Philippe Kosma, Liliane Iyalé Copyright (c) 2026 Author(s).

This study assesses the institutional performance, governance practices, diversification strategies, technology adoption, marketing structure, and economic viability of eight selected FPOs in Hisar district, Haryana. Primary data were collected from 200 member farmers and FPO officials during 2022-24 and analyzed using descriptive and comparative methods. The findings reveal significant heterogeneity across FPOs. Organizations with higher active membership, regular board meetings, and wider geographic outreach demonstrated stronger institutional foundations. Diversification into high-value horticulture, processing, and allied activities, along with moderate digital adoption, contributed to improved operational efficiency and market access. Institutional sales constituted a substantial share of total transactions, and annual sales revenues ranged between ₹25-30 lakhs with modest but stable profitability. However, financial gains were not uniformly distributed among members, indicating the need for more inclusive governance and benefit-sharing mechanisms. The study concludes that strengthening social capital, professional management, digital capacity, and value addition infrastructure is critical for enhancing the long-term sustainability of FPOs in semi-arid agricultural regions.</p> Jyoti Jangra, Manak Chand Soni, Vinita Rajput, Sunil Kumar Copyright (c) 2026 Author(s).

However, evidence shows that its micro-level effects on agripreneurship and rural livelihoods in border communities are limited. This study examines the effects of Nigeria’s land border closure on agripreneurship and rural livelihoods in selected Nigeria–Benin border communities of Ogun and Oyo States, Southwest Nigeria. A cross-sectional survey design was employed, using primary data collected from 140 agripreneurs engaged in agricultural production, trading, transportation, and processing. A multistage sampling technique was employed, and the data were analysed using descriptive statistics and paired sample t-tests. The results reveal significant variations in livelihood outcomes across actors in the agricultural value chain. While some local producers experienced temporary market protection and increased demand for domestically produced commodities, traders, transporters, and processors recorded significant declines in income, revenue, and working hours during the border closure period. Overall, the border communities experienced reduced employment opportunities due to increased transaction costs and disruptions in agricultural commodity markets. The findings reveal an uneven distribution of benefits from the border closure, with livelihood losses outweighing gains for most agripreneurs. The study concludes that although border closure policies may support short-term domestic production objectives, their implementation without adequate complementary measures can undermine agripreneurial sustainability and rural livelihoods in border communities. It recommends integrating targeted support mechanisms, improved rural infrastructure, value chain diversification, and flexible, evidence-based trade management strategies to mitigate adverse effects on livelihoods. The study contributes to agricultural trade policy discourse by providing micro-level evidence on the livelihood implications of protectionist trade measures in developing economies.</p> K. A.

The present study was conducted in the Lalitpur district of the Bundelkhand region, Uttar Pradesh, during the year 2024-2025 to examine the marketing practices of commercial and backyard poultry farmers. A total of 100 respondents, comprising 50 commercial and 50 backyard poultry farmers, were selected randomly from 20 villages across four tehsils of the district. Primary data were collected through a pre-tested interview schedule and analysed using simple percentage analysis. The findings revealed that the majority of farmers (69.00%) preferred to sell poultry products in the evening, while backyard farmers showed a relatively balanced preference between morning (52.00%) and evening (48.00%). In terms of selling points, backyard farmers mainly sold their products at their own door (54.00%), whereas commercial farmers largely depended on middlemen (78.00%). Overall, middlemen were the most common marketing channel (46.00%). The study further indicated that financial need was the sole reason for selling poultry products among all respondents. Backyard farmers showed moderate levels of egg and bird sales, whereas commercial farmers operated on a much larger scale with higher sales volumes. Additionally, backyard farmers tended to sell birds at a younger age, while commercial farmers preferred selling at older ages. The study highlights clear differences in marketing practices between commercial and backyard poultry farmers and emphasises the need for improved market access and support systems to enhance farmers’ income and efficiency.</p> Majboot Singh, Deepak Singh, Ved Prakash, Arun Kumar, Priscilla Kerketta Copyright (c) 2026 Author(s).

Plantations in Puan Cepak Village, Muara Kaman District, Kutai Kartanegara Regency https://journalarja.com/index.php/ARJA/article/view/866 <p>The use of peat soil for agricultural development faces many obstacles related to the natural properties of peat, including its relatively high acidity. Peatland is a marginal land area targeted for agricultural use, including oil palm cultivation. This study aims to assess the chemical characteristics of peat soil in oil palm plantations. This research was conducted from June to August 2024. Sampling was conducted at a 15 year old oil palm plantation owned by PT. Prima Mitrajaya Mandiri in Puan Cepak Village, Muara Kaman District, Kutai Kartanegara Regency. Soil chemical analysis was conducted at the Soil Science Laboratory, Faculty of Agriculture, University of Mulawarman. Sampling was conducted using a purposive sampling method, where the points were deliberately determined based on certain criteria. Five observation locations were selected at two different depths: 0-30 cm and 30-60 cm, resulting in 10 peat soil samples. The results of the study showed that peat soil in oil palm plantations reacted very acidic to acidic (pH 3.11 – 4.54), organic C content was classified as very high (12.64 – 25.77%), available P was classified as very low to very high (2.38 – 21,92 ppm), total N was classified as low to moderate (0.16 – 0.44%), C/N ratio was classified as very high (38.30 - 135.63), total K was classified as moderate to very high (10.92 – 101.98 ppm), soil CEC was classified as moderate to very high (20.80 – 93.20 cmol kg<sup>-1</sup>), and base saturation was classified as very low to low (8.07 – 48.67%).</p> Raden Mas Nurhartanto, Siti Aesyah, Zulkarnain, Abdul Rahmi Copyright (c) 2026 Author(s).

The severe shortage of agricultural labourers in the state has compelled farmers to transition from agricultural practices to non-agricultural activities. Structural changes in the cropping pattern resulting from labour scarcity were analysed using the Markov chain approach over a ten-year period. The result indicated that mmong them paddy has the highest retention probability with 64 per cent followed by Sugarcane retained 54 per cent and other crops. The study revealed a discernible shift in the cropping pattern, with the transition predominantly favouring the cultivation of less labour-intensive crops. The analysis of the supply–demand gap in agricultural labour further indicated that labour demand exceeded labour supply during the months of November and December, thereby reflecting the severity of labour scarcity prevailing in the study area during this period. Paddy and sugarcane demanded maximum labour in the month of December and November which coincided with harvesting and sowing operation of groundnut crops. Spatio-temporal changes map shown in agricultural labour in the patterns of distribution of agricultural labourers in areas of high decrease (above 1 per cent) in the proportion of agricultural labour were comprised of five villages of the state. Similarly, area of low decrease (below 1 per cent) has occurred over three zones of the state and areas of increase (0.02 - 4 per cent) indicated that an increase in the proportion of agricultural labour has been witnessed in a nine zones in U.T of Puducherry. Finally, the study suggested that the farm mechanization has to be encouraged among the small and marginal farmers. Further, it suggested that the MGNREGA has be implemented during the lean season.&nbsp;</p> E. Thanu Vaishnubharathi, T. Sivasakthi Devi, N. Swaminathan, S. Saravanan Copyright (c) 2026 Author(s).

Traditional heating practices used for roasting, drying is often difficult to control, leading to variations in seed quality, nutrient degradation, and reduced oil recovery. To overcome the problem, our project focuses on the design and development of a sesame heater that provides controlled, uniform, and energy-efficient heating to the thermal sensitivity of sesamum indicum. The developed system consists of an insulated heating chamber, and a natural airflow system designed to distribute heat uniformly across the seed bed. Key design parameters considered include safety mechanisms, and use of durable, food-grade materials. Performance evaluation involved assessing heat distribution uniformity, energy consumption, and the impact on seed characteristics such as colour, aroma, oil content, and oxidative stability. Experimental trials demonstrated that the developed sesame heater significantly improved heating uniformity compared to conventional systems, achieving consistent temperature distribution with minimal fluctuations. Results indicated enhanced process efficiency, reduced energy loss, and improved control over processing conditions. Treated sesame seeds exhibited better sensory attributes, higher oil yield, and reduced risk of quality deterioration. Overall, the newly designed sesame heater provides a reliable, scalable, and cost-effective solution for small- to medium-scale processors. Its controlled heating environment enhances product quality, improves operational efficiency, and contributes to greater value addition in the <em>Sesamum indicum </em>processing&nbsp;chain.</p> K.

High temperatures during grain filling can lead to lower yields. While moisture levels also influence the optimal sowing date, with adequate moisture essential for healthy growth, wheat cultivars show significant variation in their response to sowing dates. The present investigation was carried out to determine superior cultivars under various sowing dates at the Eastern Sudan New Halfa conditions. A field experiment was carried out at New Halfa during the winter seasons 2017/018 and 2018/019 to study the effects of five sowing dates:20<sup>th</sup> Oct (S1), 25<sup>th</sup> Nov (S2), 30<sup>th</sup> Nov (S3), 15<sup>th</sup> Dec (S4) and 30<sup>th</sup> Dec (S5) on productivity of The three wheat cultivars: Nebta (v1), Bohain (v2) and Debera (v3).&nbsp; The experiment was arranged in RCBD as split plot trail. All data were analyzing using Statistic (10). Means comparison was worked out using (DMRT) at 5% probability level. The results revealed that sowing dates and cultivars significantly affected phonological and yield attributes: number of spike/m<sup>2</sup>, number of spikelets/spike, 1000-grain weight, and grain yield (kg/ha). Generally, Debera (V3) recorded the latest days to heading and maturity. But Nebta cultivar (V1) gave the highest numbers of spike /m2 and the heaviest 1000- grain weight, while Bohian (V2) gave the highest number of spikelets /spike. The heaviest 1000- grain weight was recorded in first sowing date (S1). The normal sowing date (S3) maximized grain yield (4277.3 kg/ha) for V3 cultivar, while the lower yield (1266.7 kg/ha) was recorded when sowing V1 at first sowing date in the first season. Sowing V3 at the normal sowing date S3 in the New Halfa area is the best choice for getting a higher grain yield. Further research is needed to identify the most suitable sowing dates for different wheat cultivars and to develop strategies for improving yields under varying environmental conditions.</p> Abdelshukoor Haroon Suliman, Abdel Rahim Ibrihim Naeem, Badr Eldin A.

The present study examined production surplus, marketing behaviour and constraints faced by pearl millet growers in the Gird region of Madhya Pradesh, India, during the agricultural year 2019-20. Morena district was purposively selected because of its importance in pearl millet production. A total of 90 pearl millet growers were selected through stratified random sampling and classified into small-scale (&lt;2 ha), medium-scale (2-4 ha) and large-scale (&gt;4 ha) farm groups, with 30 respondents in each group. Primary data on production, consumption, marketable surplus, marketed surplus and marketing constraints were collected through personal interviews. The average production of pearl millet was 14.00 qtl, 13.00 qtl and 14.80 qtl per farm for small-, medium- and large-scale farmers, respectively. Marketable surplus was highest among small-scale farmers (10.15 qtl), followed by medium-scale (7.77 qtl) and large-scale farmers (6.54 qtl). In contrast, marketed surplus was lower across all categories, at 4.00 qtl, 3.00 qtl and 2.66 qtl, respectively. The findings indicate that immediate cash requirements, inadequate storage and limited holding capacity influenced marketing decisions. The most frequently reported constraint was lack of transportation facilities (92.22%), followed by adverse weather conditions (81.11%), malpractices by middlemen (77.77%), high price fluctuations (75.55%), lack of improved varieties (72.22%) and inadequate marketing intelligence (71.11%). The study suggests that improved transport, storage, market information, access to improved seeds and institutional marketing support may improve market participation and returns for pearl millet growers in the region.</p> Hemant Kumar Lamba, S.

Production at Farm Level in Different Areas of Bangladesh https://journalarja.com/index.php/ARJA/article/view/872 <p>This study examined the farm-level costs and returns of kenaf fibre (<em>Hibiscus cannabinus</em> L.) production in five purposively selected districts of Bangladesh: Kishoreganj, Cumilla, Brahmanbaria, Rangpur and Kurigram. Primary data were collected during the 2022 cropping season from 100 kenaf farmers, with 20 respondents from each location, using pre-tested questionnaires. Information covered input use, variable and fixed costs, fibre and stick yields, output prices and returns. Data were analysed using cost and return analysis, break-even analysis and benefit-cost ratio (BCR) estimation. Average total variable cost was Tk. 75,948 ha⁻¹, and human labour was the largest cost component, accounting for approximately 70% of variable costs. Average total cost was Tk. 1,12,478 ha⁻¹, with Kishoreganj recording the highest total cost (Tk. 1,19,275 ha⁻¹), mainly due to higher labour and input expenses. Average fibre yield was 2,892 kg ha⁻¹, ranging from 2,470 kg ha⁻¹ in Brahmanbaria to 3,306 kg ha⁻¹ in Kishoreganj. Average stick yield was 4,949 kg ha⁻¹. Average gross return and gross margin over total variable cost were Tk. 2,00,316 ha⁻¹ and Tk. 1,24,367 ha⁻¹, respectively. The average break-even price and yield were Tk. 34.08 kg⁻¹ and 1,853 kg ha⁻¹, respectively. Average BCR on a total variable cost basis was 2.64, with Kurigram and Kishoreganj showing the highest values. The results indicate that kenaf fibre production was economically viable in the surveyed areas.</p> Madhuri Rani Roy, Mujibul Hasan Chowdhury, Md. Babul Hossain, Md.

Genotypes in Relation to Resistance against Aphid (Uroleucon compositae Theobald) https://journalarja.com/index.php/ARJA/article/view/873 <p>The present investigation was conducted during the rabi seasons of 2023-24 and 2024-25 under field conditions to identify morphological traits associated with resistance to the safflower aphid, <em>Uroleucon compositae (Theobald)</em>, in safflower (<em>Carthamus tinctorius L.</em>) genotypes. Twenty safflower varieties/genotypes were evaluated in a randomised complete block design with three replications, without adopting plant protection measures. Observations were recorded for quantitative traits, including plant height, days to 50 per cent flowering and days to maturity, and for qualitative traits, including leaf colour, leaf nature, flower colour, plant type and stem nature. Aphid infestation was assessed using foliage drying grade and Aphid Infestation Index. Considerable variation was observed among the tested genotypes for aphid response and morphological characters in both years. Based on pooled resistance classification, fourteen genotypes, namely PBNS 184, PBNS 40, SSF 1371, PBNS 12, PBNS 86, PBNS 154, GMU 4429, GMU 6026, GMU 1765, GMU 1603, GMU 3095, GMU 5032, GMU 3852 and SSF 1565, were categorised as moderately resistant. Four genotypes, namely GMU 1059, GMU 1287, GMU 3929 and GMU 774, were categorised as susceptible, while GMU 2944 and C-4 were highly susceptible. Quantitative traits did not show a consistent association with aphid resistance. In contrast, qualitative traits showed a clearer relationship with resistance behaviour. Moderately resistant genotypes were generally characterised by pale green, shiny and thin leaves, a spiny plant type, and hard and thick stems, whereas susceptible and highly susceptible genotypes generally possessed dark green, leathery thick leaves, succulent stems and predominantly non-spiny plant type. The findings indicate that qualitative morphological traits may be useful selection criteria in breeding programmes aimed at improving safflower resistance to aphids.</p> Avinash S. Mahale, C. U.

This study evaluated the perceived effectiveness of public agricultural extension communication channels in disseminating sunflower production information among farmers in Nay Pyi Taw Union Territory, Myanmar. A cross-sectional survey design was used, and primary data were collected from 161 sunflower farmers through structured questionnaires administered during face-to-face interviews. Descriptive statistics, including frequency, percentage, mean, mean rank and standard deviation, were used to analyse the data. The communication channels were classified into individual, group and mass communication approaches. The findings showed that group communication channels were perceived as the most effective overall, followed by individual communication channels, whereas mass communication channels were perceived as moderately effective. Among the individual methods, farm and home visits received the highest effectiveness rating. Within the group communication category, demonstration plots, group meetings, farmer field schools and training programmes were highly valued because they supported participatory learning, practical demonstration and knowledge sharing. Among the mass communication methods, television was perceived as the most effective channel, while radio was perceived as the least effective. The findings indicate that an integrated extension communication strategy combining group, individual and mass communication methods may improve information dissemination, support technology adoption among sunflower farmers and contribute to Myanmar’s edible oil self-sufficiency strategy.</p> Naing Yan Hein, Soe Paing Oo, Nwaye Ei Khing Phyu, Aye Moe San Copyright (c) 2026 Author(s).

The study was based on primary data collected from 120 Kinnow growers and market intermediaries using a structured interview schedule. The results revealed that Kinnow cultivation is mainly practised by small and medium farmers. Most respondents were in the middle-aged group (31–50 years), indicating active participation in farming and marketing activities. The literacy level was moderate, with many farmers having secondary or higher education, which supports the adoption of improved practices and better market awareness. Agriculture was the primary occupation, though some farmers had additional income sources such as dairy and business. Three marketing channels were identified: Producer → Consumer, Producer → Retailer → Consumer, and Producer → Wholesaler → Retailer → Consumer. Among these, the second channel was most commonly used due to easy access to local markets. However, the first channel was found to be the most efficient and profitable because it involved fewer intermediaries. The third channel was mainly used for bulk sales but resulted in higher costs and lower returns to farmers. The study showed that marketing costs, margins, and price spread increased with the number of intermediaries. The producer’s share in the consumer’s rupee was highest in direct marketing and lowest in the channel involving wholesalers. The major constraints identified included price fluctuations, high transportation costs, lack of cold storage facilities, exploitation by middlemen, and poor access to market information. The study suggests improving direct marketing channels, infrastructure, and market information systems to enhance efficiency and farmers’ income.</p> Dinesh Kumar Saharn, Rebecca Nelson, Suresh Saharn Copyright (c) 2026 Author(s).
