The most promising legume was selected, grown and incorporated insitu along with varying levels of inorganic nitrogen fertilizer. The effects of these treatments on agronomic trait and yield of upland rice and soil chemical properties were then investigated at UNAAB and Olowo-Papa village (OP). In the first experiment three green manure crops, namely, Mucuna utilis, Canavalia ensiformis and Lablab purpureus were screened for biomass production in a Randomized Complete Block Design with three replicates. The biomass of M. utilis (25.5 t/ha) was significantly higher than those of C. ensiformis (20.4 t/ha) and L. Purpureus (2.1 t/ha). The second experiment was laid out in a split- plot design at the two sites. Mucuna, which produced the highest biomass in the first experiment, was chosen as the green manure crop. The main plot was green manure (no green manure and green manure) and N-fertilizer constituted the subplot treatment (0, 30, 60 and 90 kg N/ha). The results showed that rice plants grown on green manure plot had higher panicles/m2, number of grains/panicle and grain yield than in the control plot. The contribution of green manure incorporation to grain yield was estimated to be 56%. The plot treated with 90 kg N/ha had the highest rice yield at OP. It was found that the response of rice to N fertilizer application depended on green manuring. Mucuna grown with the late rains as pre-rice green manure has the potential of increasing the grain yield of the subsequent rice crop.

The samples of the mulberry plant were collected from the Forestry Research Institute of Nigeria (FRIN) Ibadan. The 8 varieties were planted out using 8 x 8 Latin Square experimental layout. Leaves from these varieties were used separately to feed the domesticated silkworm Bombyx mori L. The study revealed that all the eight varieties could survive in the Northern Guinea Savanna area of the country. The S41 variety had the highest survival rate (78.2%) while S34 variety had the highest leaf yield (28095kg/ha). The performances of varieties S14, S36, NG1 and K2 in terms of leaf yield were low. Leaf analysis revealed that the Nitrogen and Calcium contents of S54 were significantly higher than those of the other seven varieties. This was followed by those of K2, S30 and S34. Sodium content was found to be very high in NG1, S41, S54 and K2. Worms fed with S34 variety produced the highest cocooning percent and also performed well in the production of good cocoons. S54 produced the heaviest single cocoon, the lowest number of cocoons in 1.0kg cocoons, produced cocoons with the least quantity of leaves and its effective rate of rearing determined by the weight of the cocoon produced was superior to others. Variety S54 based on the performances of the silkworms fed with its leaves has therefore been selected for cultivation in the semi arid area of Nigeria.

Simple random sampling technique was used to select one hundred and twenty farmers from a list of six hundred farmers in the study area. A significant relationship exists between the level of income generated from cashew fruits and education (X2 =9.700; P= 0.05). In conclusion, farmers generate income from raw fruits only and have negative disposition towards adding value to cashew fruits for income generation. It is therefore recommended that cashew fruit farmers be educated on processing potentials of cashew fruits to enhance their income and improve their standard of living in the study area.

One hundred and twenty five (125) arable crop farmers were interviewed using two stage stratified simple random sampling technique while information from sixty (60) users and forty (40) non-users of farm machinery was used for analysis. Data collected were analysed using descriptive statistics, Logit regression analysis, budgetary analysis and test of difference of mean. The study revealed that, relative to non-users of farm machinery; majority of the farmers using machinery were relatively younger, more educated, cultivated larger area of farmland and have more exposure to extension agents. The logit regression results revealed that farm size (p ≤ 0.10), farm income(p ≤ 0.10) and farming experience ( p ≤ 0.10) significantly affected the use of farm machinery in the study area. The test of hypotheses revealed that users of mechanisation significantly made more profit (N73, 299.69) than non-users (N23, 153.87) (p ≤ 0.10). The study recommended that farmers should be encouraged to cultivate large farm holdings through collective or cooperative effort and that majority of the farmers should be more enlightened to use farm machinery as an avenue for improved farm productivity and profitability.

Data on yield and yield traits were subjected to combined analysis of variance. There were variations in the years of production as the relative performance of the genotypes with respect to all the traits were significant under the genotype x year (Gen. x yr) effect. However, days to maturity, number of pods per plant and number of branches per plant were significant under the genotype x location (Gen. x loc.), and the third order interaction effect of Gen. x loc. x yr. Branch number per plant gave negative but significant phenotypic correlation with number of seeds per pod and weight of seeds while its correlation with seed yield was positive in Ogbomoso and Abeokuta locations. Significant genotypic correlation were observed between number of seeds per pod with seed weight and seed yield for Ibadan and Ogbomoso locations though its correlation with seed weight in Ogbomoso location was negative. The significant genotypic correlation of days to maturity with pod number and branch number ensures that these traits would be successfully selected for in yield improvement of soybean for Abeokuta and Ogbomoso locations. Number of seeds per pod and days to maturity with high heritability estimates and significant genotypic correlations can be reliably selected for when soybean improvement is targeted for Ibadan and Ogbomoso specific locations.

The highest protein level attainable at the end of the 20th day was 15.95% and the least was 4.76%. Proximate and detergent fibre composition of in-vitro degraded cassava peel samples were determined. Experimental diets were formulated with graded levels of degraded cassava peels for weaned pigs. Diets 1, 2, 3, 4 and 5 contained biodegraded cassava peels at the expense of cassava flour at levels 0, 10, 20, 30 and 40%, respectively. Diet 3 was found to be the best utilized with feed conversion ratio (2.74+0.10), while diet 2 with the poorest conversion (3.20+0.07) was the least utilized. The best and least weight gain were recorded in the pigs fed diets 3 and 5, respectively. Biodegradation increased the crude protein content of the cassava peels, which was 15.95% at 20 days compared to 4.76 and 10.13% at 0 and 5th day, respectively. Phytic and tannic acid contents were also reduced by in-vitro degradation. Colonial counts of micro-organisms from faecal samples of pigs ranged between 108 – 1010 cfu/ml. Presence of Mucor spp and Pseudomonas spp. was noted in the experimental diets, while isolates of Lactobacilli spp., E. Coli, Pseudomonas spp. and yeast were the major micro-organisms in the faecal samples. It is therefore, concluded that biodegraded cassava peels should not be used in pig's production, as parameters studied were not significant (P>0.05) and cost of feed per kg live weight gain was best in control.

Two estimates of RA were computed with the objective to identify a more suitable approach for estimating the RA of a cultivar under low soil moisture regime by using data collected over four cropping cycles from 48 local and exotic sugarcane germplasm collections. The first estimate was computed using the formula: Rai = 100Sri/PC where RA of a trait i is defined as the ratio of the second ratoon crop (SRC) yield of trait i to the plant cane (PC) yield of trait i expressed as a percentage while the second approach is a generalized formula: Rpi = 100[1-(X2-Xi)/Xa] where Rpi = annualized yield of cane, Xa = the reference yield = [yield of plant cane + yield of first ratoon]/2 and Xi = the individual ratoon yield. Genetic variance (δ2g) estimates for RA were comparable for both methods except for brix and kg-brix. Broadsense heritability estimates (H2B) of RA for cane yield was 0.76 in Method I while it was 0.64 in Method II. Brix had estimates of 0.82 and 0.64 for Methods I and II respectively. Genotypes with poor RA were characterized mostly by sharp decline in cane yield especially between the plant cane and first ratoon crop while those with good RA had the greatest yield decline between the first and second ratoon crops. The similarity in estimates of RA with the two methods or in the genotypes selected on the basis of cane yield, brix and Kg-brix suggests that either of the two methods is equally suitable in estimating RA either under ideal growing conditions or in a moisture stress environment.
