The experiment was laid using Randomized complete block design with 8 replicates. The treatment consisted of sesame, groundnut, wheat and bambaranut. Each treatment was repeated eight times, the results reveal K-coefficient for determination of leaf area to be 0.43, 0.62, 0.53 and 0.64 for sesame, groundnut, wheat and bambaranut respectively. The use of multiple regression equation improves the prediction over linear measurement. Also, simple and multiple regression analysis was carried out in other to increase precision in use of leaf area in the four treatments which are; sesame (Y=1563.632 + 0.409x1, Y= 1563.632 + 0.409x1-45.73x2), groundnut (Y =-3175.794 + 0.611x1, Y= 3175.794+0.611x1 +56.825x2), wheat (Y= 376.084+0.265x1, Y=376.084+ 0.265x1-4.559x2) and bambaranut (Y=162.603 + 0.615x1, Y=162.603 + 0.615x1 +15.677x2). The data on leaf area and leaf number value of all the four crops were fitted into linear regression analysis separately as well as combined data, it shows significant difference or improvement over the use of linear measurement.

A field experiment was therefore conducted during the rainy seasons of years 2018 and 2019 respectively, at the student Research and Demonstration Farm, Faculty of Agriculture, Kogi State University, Anyigba. The aim of the trial was to evaluate the influence of Nitrogen-fertilizer-starter dose and phosphorus on growth, yield attributes, final Grain yi eld and Grain Crude Protein content of three varieties of cowpea in Anyigba. The N-fertilizer rates were-0, 10 and 20kg N/ha applied as urea, while the P rates were 0, 37.5 and 75.0 Kg P2O5/ha as single super phosphate (26. 0% P2O5). Factorial experiment was used and treatments were arranged and laid out in Split Plot Design (SPD) and replicated three times. The results indicated that for both years, Nitrogen and Phosphorus application resulted in significant (P < 0.05) increases in growth, some yield attributes and final Grain Yield of the three varieties of cowpea. One major significant outcome of the exp eriment was that while Nitrogen application significantl y (P<0.05) increased number of nodul es produced/plant for all the sampling periods and for both years, phosphorus application how ever had no significant (P>0.05) influence on the character (nodule) throughout the sampling periods and for both years. The highest grain yi eld of 0.93tonha-1 was obtained with application of 10 kg N and 37. 5 Kg P2O5/ha. Application of 10.0 Kg N ha-1 and 37.5 Kg P2O5 ha-1 of Phosphorus significantl y (P<0.05) yielded a Crude Protein Content of 20.83% and 23.31% over the control plot which gave 20. 54% and 19.17% Crude Protein respectively in 2018 trials. This trend was equally maintained in 2019 trials.

The study area which is Kogi State, to determine the effect of sheep dropping rate and staking on the yield and yield component of cucumber. Staked and unstaked and four treatment levels (0, 10, 20 and 30 kg per hectare) were evaluated. The study was conducted as a 2x1 factorial laid out in randomized complete block design (RCBD) with three replications. Treatment means were separated using least significant difference (LSD0.05). The result generated from the study showed that number of fruits, number of marketable fruits and weight of fruits. Staking had no significant effect on number of fruits, but showed significant effect on number of branches, number of leaves and plant height. The staked treatment constantly performed better with higher values than the non-staked treatment. Result obtained from data analysis shows that Cucumber growth, yields and yield components were enhanced with the incorporation of Poultry droppings across various treatment rates. Hence for maximum production of cucumber staking and optimum sheep dropping should be adopted.

However, yield is a complex character, its direct improvement is difficult. Knowledge is respect of the nature and magnitude of associations of yield with various component characters is a prerequisite to bring improvement in the desired direction. This research was conducted at Kogi State University Student Research and Demonstration Farm (Longitude 07°06 1 N; 43°E), Anyigba, Kogi State, to investigate the association of some yield characters with yield in eggplant (Solanum melongena L.). Two cultivars of eggplant NC-2 (green) and NC-1 (off-white) were laid out in a randomized complete block design (RCBD) with four replications. Yield component such as number of branches, fruit diameter, number of nodes, and number of fruits shows significant and positive association with yield. Correlation coefficient (r) for yield versus other growth and yield component: Plant height, number of branches, fruit diameter, number of nodes, and number of fruits were found to be 0.983, 0.962, 0.959, 0.906 and 0.891 respectively.

The use of mineral fertilizer in tropical soils can help solve the problem of low soil nutrients. So far, only Nlevel have been recommended in most of the region of Nigeria, the specific requirement for varieties have not or in most cases been overlooked, therefore determination of the interaction of N-level with variety is necessary as it will enable researchers determine specific level of N-fertilizer for specific variety. Thus research was conducted on Kogi State University Student Research and Demonstration Farm (Longitude 07°06 1 N; 43°E), Anyigba, Kogi State, to investigate the influence of N-fertilizer on the yield and yield components of eggplant (Solanum melongena L.) the experiment consisted of two varieties of eggplants green variety encoded as NC-2, the Off-white variety encoded as NC-1 and three urea fertilizer levels (0, 100, 200kgN/ha). Factorial combination of the treatments gave a total of six treatments which was laid in a Randomized Completed Block Design (RCBD) with four replications. Urea fertilizer was applied in 2-split doses first at 3weeks after planting and the second dose was applied at fruiting. Parameters measured include: plant height, number of leaves, stem girth, fruit diameter, number of nodes, number of branches, number of fruits per plant, number of flowers per plant, fruit weight. Fertilizer application significantly increased the yield of the two varieties. However, NC-2 (green variety) appears to respond more to higher N-application (up to 200kgN/ha) as compared to NC-1 (offwhite variety). Also, fertilizer had significant effect on vegetative characters, yield and some yield components. The yield were found to be statistically at par.

Treatment consisted of poultry manure which was applied at 0, 7.5 and 15t/ha and inorganic fertilizer (NPK 20:10:10), applied at the rate of 0, 0.2, 0.4 and 0.6t/ha respectively. The experiment was laid in a Randomized Complete Block Design (RCBD) with three replicates following all agronomic practices as recommended. Combined rates of poultry manure at 15t/ha and 0.6t/ha of fertilizer were found to significantly increased (P≤0.05) growth characters such as number of leaves, vine length at 4, 6 and 8WAS. Longest vines of 602.75cm and 213.75leaves was obtained with combined application of 15t/ha PM + 0.6t/ha NPK fertilizer at 8WAS respectively. Similarly, Fruit length, Number of fruits, Fruit weight/plant, Fruit yield/ha were significantly influenced (P≤0.05) by the combined application of 15t/ha PM + 0.4t/ha NPK, while the control plots consistently gave the least yield across sampling periods.

However, the Relative Yield Potential (RYP) and Land Equivalent Ratios (LER) of these mixtures are given less prejudice especially in monetary terms by ancient farmers. This necessitate an experiment conducted during the 2016 and 2018 rainy seasons. The treatments consisted of Maize (TZESR-Open Pollinated), Cowpea (Sampea-7), Peanut (Samnut-24) and Soybean (TGX 713-09D) as sole crops sown at seed rates of 25 and 50 kgha-1 for maize and legumes respectively. The grain legumes were intercropped with maize in the ratio of 4:1, 2:1 or 1:1 as additional rows in between the normal rows of maize planted at a spacing of 75 x 25cm. Results revealed that intercropping of maize with either cowpea, peanut or soybean in 2:1 ratio was most productive in terms of maize equivalent yield and declined thereafter, with increase in the legume proportion, though maintained its superiority over sole planting of maize. Maize intercropped with soybean in the ratios 4:1 gave the highest mean biological maize equivalent compared to its sole planting at different combinations of legumes. Maize + Peanut gave the highest mean Land Equivalent Ratio (1.81) followed by maize + Cowpea (1.74) and maize + soybean (1.59) all sown in the ratio of 2:1. Intercropping of legumes with maize appeared to be more aggressive than sole planting of maize or legumes. Maize + Peanut (2:1) gave the highest mean Monetary Advantage Index (MAI) of 7789.0, Mean Yield Index (MYI) of 79.0. However, regardless of the ratio in which Maize + peanut was combined, result of 47% MAI showed a greater biological relationship, effective competition, hence recommended. Highest cost/benefit ratio (5.09 and 4.45) was obtained with maize + soybean (4:1) during 2016 and 2018, respectively.

Number of branches produced per plant was found not to be significant with variety, days to first flower and 50% flowering varied significantly with varieties grown. Seed yield per hectare, number of pods per plant, number of seeds per pods pod yield and pod length varied significantly (P≤0.05) with variety. The highest seed yield of 1147 kg/ha was obtained with IT89KD288. However, this yield was not significantly different from those obtained with Ife-Brown (920 kg/ha), Sampea-4 (1027 kg/ha), Dippa (733 kg/ha) and Tchad (706 kg/ha). The performances of some of the varieties in relation to others, even though was slightly higher, but was found not to be statistically significant at 5% level of probability. The association characters also shows that positive and non-significant relationships existed between seed yield and numbers of seeds/pod, number of pods per plant, pod length, number of branches/plant, days to first flower and days to 50% flower. Keywords: Local varieties; improved varieties; seed yield per hectare; pod length; number of seeds per pods; number of pods per plant.

The experiment was laid in a Randomized Complete Block Design (RCBD) with four replications. In the trial, it was found that yield characters such as number of seed/cob, cob length, cob/plant, and 100-seed weight exerted much influence on the seed yield and was found to be significantly (p≤0.05) and positively associated with seed yield/plot. However the number of seed/cob and cob length contributed 69% (0.83 2) and 74% (0.86 2) respectively to the total seed yield variations. The path coefficient analysis indicates that cob length exert the strongest influence (1.70) on grain yield followed by the number of seed/cob (1.50) and 100-seed weight (1.00). Keywords: Direct effect and Indirect effect; residual factor (R); coefficient of determination (R 2).

A t-test showed that all characters measured were not statistically significant at 5% level of probability. The mean yield obtained from improved varieties (808.02kg) was though numerically higher by 3.80 % than its local counterparts (778.72kg), this was however not statistically significant. Mean differences of 54.76kg/ha (5.30%), 0.35seeds (3.30%), 0.40pods (4.44%) and 0.21cm (1.46%) was obtained for Pod yield, Number of seeds per pod, Number of pods per plant and Pod length respectively. These were not statistically significant at 5% level of probability. Analysis of variance (ANOVA) conducted for all the varieties showed significant differences (P≤0.05) in individual yield performances. The highest seed yield of 1.147tonha-1 was obtained for IT89KD288, while a least seed yield of 600kgha-1 was obtained with Sampea-5.
