Aims: In this study, it was aimed to determine parcel value numbers used in land consolidation studies in more detailed.

Study Design: 14 different questions were created considering properties of the study area. Parcel value numbers of the study area were determined according to these detailed questions.

Place and Duration of Study: The study was carried out in 3 districts located in the Aksu province in Antalya in 2017.

Methodology: Generally, parcel value numbers were determined according to the parcel index. The current parcel index equation cannot perform a detailed calculation because it uses just three parameters such as soil index, productivity score and location score. However, in the new detailed equation created in this study, parcel index values were determined by using soil index and land quality index, which consisted of 14 different questions taking into account the properties of the region applied. In addition, proportions of parameters used in the current equation were revised in the new equation created. Results obtained with new detailed equation were compared with the results obtained by the institution that performs land consolidation with the current method in the region.

Results: As a result, the total parcel value numbers of the two districts were calculated higher in the new equation than the current equation. The total parcel value number in just one of the districts was determined lower in the new equation than the current equation.

Conclusion: According to results obtained in the study, the new equation can be used in the land consolidation studies instead of the current equation because the new equation has provided a much more detailed and fair land distribution.

The nutrients digestibility, nitrogen utilization and blood profile of West African Dwarf (WAD) goat fed cassava peels with urea-molasses multi-nutrients block (UMMB) supplements was investigated in a twelve weeks experiment. Twenty WAD goats that weighed 8.33±0.35 kg on average were assigned to each of the five experimental diets that contained cassava peels without UMMB supplement (treatment 1) and with UMMB containing 0% urea (treatment 2), 5% urea (treatment 3), 10% urea (treatment 4) and 15% urea (treatment 5), in a completely randomized design (CRD). Results of the study revealed that nutrients digestibility were significantly (P<0.05) influenced by UMMB supplementation. Goats fed diet T4 also had the highest values of digestibility coefficients of dry matter (DM), crude protein (CP), crude fibre (CF) and nitrogen free extract (83.05%, 71.97%, 67.64% and 71.34%)  respectively. Nitrogen retention was significantly (P<0.05) influenced by dietary treatments, the values ranged from 0.75 g/day (diet T1) to 6.07 g/day (diet T5). Haematological indices and serum biochemistry were within normal range for WAD goats.

Conclusively it can be said that urea-molasses multi-nutrient blocks is offers a reliable source of protein for improved nutrients digestibility and nitrogen utilization by WAD goats fed cassava peels without detrimental effects on the wellbeing of the goats.

Aims: The objectives of this study are to assess the effect of pollination methods on the seed quality and yield of progenies from an early-maturing maize population and to determine the relationship between seed quality and grain yield of the different progenies. 

Study Design: Experimental field design was split plot design with three replicates using the stratum for developing the progenies as the main plot and the pollination methods as the sub-plots.

Place and Duration of Study: Seed Science Laboratory and Teaching and Research Farm, Obafemi Awolowo University Ile-Ife, Osun State, Nigeria between 2013 and 2015.

Methodology: Self, half-sib and bulk-sib pollination methods were used to produce progenies during the late cropping seasons of 2013 and 2014. Evaluation of the progenies developed by the three methods was  carried out in the laboratory in 2014 for progenies developed in 2013 and 2015 for 2014 developed progenies. The field experiment was conducted in the early and late cropping seasons of 2014.

Results: Pollination method had no significant effect on germination traits of progenies generated in both years, but significantly affected most of the seedling vigour traits. In 2014, there was no significant effect of pollination method on seed weight before ageing, but germination percentage of progenies from self (86%) and half-sib (90.41%) pollinations were significantly higher than that of bulk-sib (46.40%) pollination after ageing. The speed of germination from self (4.04) and half-sib (4.02) pollinations were significantly faster than that of bulk-sib (5.23) pollination after ageing. Half-sibs and bulk-sibs progenies performed better than the self-pollinated progenies for anthesis-silking interval (2.39, 2.28 and 3.50 respectively) ear length (11.96 cm,12.23 cm and 10.06 cm respectively), ear diameter (3.92cm, 4.00cm and 3.56 cm respectively), kernel row number (12.04, 11.92 and 11.77 respectively) and grain yield (1.63, 1.72 and 0.72 tons/ha respectively).

Conclusion: Self-pollination method produced the highest number of seeds while bulk-sibs pollination method produced seedlings that are more vigorous. Bulk-sib and half-sib progenies produced higher grain yield than the selfed progenies. Only root number of the half-sibs progenies had a positive relationship with yield in the early cropping season

Solenostemon rotundifolius (frafra potato) is an important food security crop in areas where it is cultivated in Ghana. However, the crop suffers research neglect in Ghana. More research on the crop is therefore needed for the crop to experience any form of meaningful improvement and utilisation beyond the area of its cultivation in Ghana. This present experiment therefore aimed to study the post-harvest proximate composition and water activity of three cultivars (black, white and brown cultivars) of frafra potatoes (Solenostemon rotundifolius) from the Upper East Region of Ghana. The white cultivar recorded the highest water activity value of 0.72 whiles the black and brown cultivar both recorded a lower water activity value of   0.68. The white cultivar recorded the highest moisture content of 7.20% whiles the brown and black cultivars recorded moisture content of 7.00% and 6.60% respectively. The brown cultivar recorded the highest protein content of 5.25 %, followed by 4.81% for the black cultivar and 4.38% for the white cultivar. Considering the ash content, the brown cultivar recorded a higher value of 4.00% followed by 3.80% recorded by the white cultivar and least value of 3.20% recorded by the black cultivar. The white cultivar recorded the highest fat content of 1.00% whiles the brown and black cultivar both recorded the lowest fat content of 0.20%. The black and brown cultivars both recorded the same higher fibre content of 1.00% followed by the lowest fibre content of 0.20% by the white cultivar. The black cultivar recorded the highest Nitrogen free extract (NFE) content (84.19%) followed by that of the white cultivar (83.42%) with the least being that recorded by the brown cultivar (82.55%). In all, mean water activity, moisture, protein, ash, fat, fibre and NFE values for the three cultivars were 0.69±0.02, 6.93±0.31%, 4.81±0.44%, 3.67±0.42%, 0.47±0.46%, 0.73±0.46% and 83.39±0.82% respectively. The mean moisture content and water activity recorded in this study indicate that processing frafra potatoes into flour will extend its post-harvest shelf life. Based on the moisture content and water activity values reported in this present study, the black cultivar of frafra potatoes will have the longest postharvest shelf life followed by the brown and white cultivars when processed into flour.

Thirty-seven Onion (Allium cepa L.) genotypes comprising of twelve parents (12) and twenty-five hybrids were evaluated at the Fadama Teaching and Research farm of the Department of Crop Science, Usmanu Danfodiyo University, Sokoto during the 2015/2016 dry season. The objective of the study is to determine the correlation of characters among the 37 genotypes. The treatments were laid out in a Randomized Complete Block Design (RCBD) with three replications. After harvesting, the genotypes were stored for five months using farmers practice. The analysis of the results indicated highly significant (P<0.001) positive correlation between plant height and leaf area (1), plant height and leaf area index (0.84676), plant height and number of leaves (0.46727) plant height and percentage loss (0.43356) leaf area and leaf area index (0.85459), leaf area and cured bulb weight (0.47029), leaf area and percentage loss (0.50254) number of leaves and cured bulb weight (0.51363), number of leaves and percentage loss (0.43259), bulb diameter and bulb length (0.36367), bulb diameter and percentage loss (0.68209). Results obtained indicated highly significant (<0.001) negative correlation between leaf area index and days to maturity (-0.29333), leaf area index and number of leaves (- 0.29333), number of leaves and bulb diameter (- 0.02255), and between days to maturity and percentage loss (- 0.86679). Results obtained also revealed significant (<0.05) negative correlation between number of leaves and percentage bolting (- 0.26466) number of leaves and average bulb weight (- 0.26466) number of leaves and days to maturity (- 0.24959) days to maturity and average bulb weight (0.02255) cured bulb weight and days to maturity (-0.24001). The results of the study, therefore, conclude that Onion genotypes with longer maturity are best for storage.
