Extra Sweet (Md2) Vivo Plants in Greenhouse 2020-09-24T18:44:50+00:00 Kanga N'guessan Martial Cherif Mamadou Koné Tchoa Sanogo Souleymane Kanga Ahou Nadia Tuo Seydou Affery Arthur Martin Kassi Koffi Jean Fernand Martial Bomisso Edson Lezin Camara Brahima Sorho Fatogoma Dick Acka Emmanuel Koné Daouda <p>Pineapple has several types of organs that can be used for its multiplication. Its natural multiplication is particularly slow, as it is necessarily vegetative because the species is self-sterile (on average 2 suckers per strain in six months). The supply of pineapple rejects is not always easy for those who want to grow pineapple on large areas. This study was initiated to improve the production of MD2 pineapple seed (suckers or vivo plant) per pineapple strain fragment. Thus, the production of two types of pineapple strains, young and old strains (The young strains bear green leaves and make up all the strains that have produced fruit. Their ages range from 0 to 12 months after the fruit has been harvested. The old strains without green leaves are older than 12 months of age), was evaluated on three types of substrates, namely : S1, 100% coarse coconut fibre; S2, 2/3 coarse coconut fibre + 1/3 sawdust and S3, 3/4 coarse coconut fibre + 1/4 chicken droppings. The seeding of the fragments on the substrates it's made in a completely randomized device in a greenhouse. The study carried out was repeated twice during the same period. Results showed that vivo plant production varied according to the age of the pineapple strain. With fragments of young strains, a mean of 3.96 ±1.74 (average ± Ecart-type) vivo plants per fragment was obtained compared to 3.07±1.63 (average ± Ecart-type) vivo plants at fragments of old strains. This difference was significant with P = 0.000. The effect of substrate was significant on the number of plants produced per strain fragment. More plants per fragment were obtained on S2 with 3.53±1.1 (average ± Ecart-type) vivo plants than on the other substrate types S1 and S3 with 3.22±1.3 and 3.09±1.02 (average ± Ecart-type) vivo plants per strain fragment, respectively. This difference was significant with P= 0.002. This study showed that a strain fragment after fragmentation gives only 3.96 ± 1.74 plants in six months. This production of pineapple vivo plants is influenced by the type of substrate and the age of the strain. Thus, young strains grown on a substrate that maintains moisture should be recommended for sustainable production of pineapple vivo plants.</p> 2020-08-29T00:00:00+00:00 ##submission.copyrightStatement## Assessment of the Exposure Risk to Mycotoxins from Stored Maize (Zea mays L.) in Triple Bags with Aromatic Plants Leaves (Lippia multiflora and Hyptis suaveolens) in Côte d’Ivoire 2020-09-24T18:44:49+00:00 Yao Vanessa Gaël G. Henri Marius Biego Konan K. Constant Coulibaly Adama Sidibe Daouda <p>In Côte d’Ivoire, maize is second cereal most cultivated and consumed after rice. In bad storage conditions, corn may be contaminated by mycotoxins (aflatoxin B1, total aflatoxins, ochratoxin A, fuminosin B1, zearalenone). The aim of this study was to assess the exposure risk of these mycotoxins for maize stored in triple bags in presence of aromatic plants leaves (<em>Lippia multiflora</em> and <em>Hyptis suaveolens</em>). The contents of water activity, aflatoxin B1 (AFB1), total aflatoxins (AFT), ochratoxin A (OTA), fuminosin B1 (FB1) and zearalenone (ZEA) were studied and monitored. The levels of AFB1, AFT, OTA, FB1 and ZEA resulted from maize grains treated with plants leaves were significantly lower than those recorded with untreated maize of control bags. The estimated daily intakes in AFB1, AFT, OTA, FB1 and ZEA, deriving with consumption of maize from experimental batches stored for 18 months are respectively 1.69 ± 0.00 - 2.09 ± 0.01 ng/kg bw/day, 8.66 – 10.91 ng/kg bw/day, 1.86 ± 0.01 - 2.47 ± 0.01 ng/kg bw/day, 2.01 ± 0.05 - 3.01± 0.05 ng/kg bw/day and 1.89 ± 0.12 - 3.56 ± 0.04 ng/kg bw/day. These levels are lower than the estimated intakes from maximal reference value (EDILM) for OTA, FB1 and ZEA. For aflatoxin B1 and total aflatoxins, the estimated daily intakes are lower than the estimated intakes from maximal reference value (EDILM) during, respectively, 15 storage months and 10 storage months. However, after 18 storage months, exposure risk of aflatoxin B1 is higher than the estimated intakes from maximal reference value. This inexpensive and easy-to-use treatment should be popularized among farmers</p> 2020-09-16T00:00:00+00:00 ##submission.copyrightStatement## Influence of Date of Sowing on Growth and Yield Performance of Field Pea (Pisum sativum L.) Genotypes 2020-09-25T02:33:06+00:00 Bulbul Ahmed Ahmed Khairul Hasan Biswajit Karmakar Md. Sahed Hasan Fahamida Akter Parth Sarothi Saha Md. Ehsanul Haq <p>An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during October 2014 to March 2015 to study the growth and yield performance of field pea varieties as influenced by date of sowing. The experiment comprised of two factors namely, date of sowing and variety. Date of sowing comprised of 29 October, 13 November and 28 November and the variety comprised of BARI motor-1, BADC motor-1, Natore local and Narail local. The experiment was laid out in a split plot design with three replications. The results indicate that all the growth characters were varied significantly at different days after. Those growth characters except leaf area index were highest for the crop sown on 28 November. The growth characters were highest in variety Natore local and lowest in Narail local except dry matter it was lowest in BADC motor-1. The interaction effect of 28 November sowing, Natore local was highest for all of the growth parameters except leaf area index it was highest on 13 November sowing and the interaction on 29 October sowing BARI motor-1 gave the lowest value. Most of the yield contributing parameters significantly affected by sowing date. The highest seed yield (827.7 kg ha-<sup>1</sup>) and other yield contributing characters were found on early sowing (13 November) and the lowest seed yield (534 kg ha-<sup>1</sup>) and other yield contributing characters was at 28 November sowing. Variety had significant effect on yield and yield contributing parameters. The highest seed yield (1032.2 kg ha-<sup>1</sup>) and Stover yield (3221.35 kg ha-<sup>1</sup>) was obtained from Natore local while Narail local gave lowest (469.1 kg ha-<sup>1</sup>) seed yield and lowest Stover yield. The interaction of 13 November with Natore local gave the highest seed yield (1319.3 kg ha-<sup>1</sup>) and lowest seed yield was produced by Narail local (330.35 kg ha-<sup>1</sup>) by late sowing (28 November). It can be concluded that, vegetative growth were highest at 28 November sowing and yield components gave highest value on 13 November sowing. Highest yield was produced by Natore local at 13 November sowing but yield was reduced drastically when the crop sown on 28 November. So, it is clear that the optimum date of sowing for field pea is at 13 November.</p> 2020-09-21T00:00:00+00:00 ##submission.copyrightStatement##
