Field experiment was conducted at University of Uyo Teaching, research farm during the 2018 and 2019 cropping seasons to assess the effect of fertilization on cocoyam-based intercropping systems. The experiment was laid out in a randomized complete block design with three replications. Treatments were six fertilizers rates - 0kg/ha, NPK200kg/ha, NPK400kg/ha, PM2.5t/ha, PM5.0t/ha, Mixture (NPK200kg/ha + PM2.5t/ha) and six crop mixtures - Sole Cocoyam, Sole Melon, Sole Maize, Cocoyam + Maize, Cocoyam + Melon and Cocoyam + Melon + Maize). Result analysed with analysis of variance revealed PM2.5t/ha, NPK400kg/ha and Mixture (NPK200kg/ha + PM2.5t/ha) gave higher plant height, leaf area, stem girth in sole cocoyam, maize and melon respectively. PM2.5t/ha favoured leaf area, stem girths of cocoyam, maize with cocoyam + maize, cocoyam + melon and cocoyam + melon + maize crop mixtures. PM5.0t/ha gave higher values of corm, cormels, cormels weight, cormels number and cormels length in both sole cocoyam and mixtures (cocoyam + melon, cocoyam + maize, cocoyam + melon + maize) in both seasons respectively. PM2.5t/ha gave higher values of maize grain yield with cocoyam + maize, cocoyam + melon + maize crop mixtures. PM5.0t/ha and NPK400kg/ha gave higher melon seed values with cocoyam + melon and cocoyam + Melon + maize. Conclusively, it is recommended that application of organic fertilizer promotes higher yields and yield components in both sole and crop mixtures of cocoyam and maize respectively.

This work was conducted to quantify biochemical coumpound in tilled and dried Lippia multiflora Mold leaves. The study evaluated the geographical variation of this plant in term of its proteins, cellulose, vitamin, minerals, mixed phenolic compounds on leaf materials collected from Abidjan, Toumodi and Bondoukou. The results showed a variability in the physicochemical composition from L. multiflora leaves. Correlation analysis revealed significant differences in protein, cellulose, vitamin minerals and mixed phenolic coumpound. Our results indicated the importance of geographic origin of cultivation areas and leaves’ ripeness. Proteins content is more than 9% of DM (Dry Matter). C vitamin and carotenoids content ranged from 17.34-27.71 mg/100g DM and 113.94- 136.97 µg /100 mg of DM, respectively. The leaves had high values for potassium (13.32 - 26. 72 mg /100 mg of DM). Calcium and iron ranged from 7. 87 - 29.25 mg/100g of DM, 0.09 -0.18 mg/100g of DM. The investigated phenolic compounds showed substantial polyphenols, flavonoids and alkaloids with the highest coumpound in younger leaves and lowest in older leaves. Nutrient concentrations of L. multiflora leaves in Abidjan were greater than the other two locations.

Field trials were conducted at two locations during the 2019/2020 dry season to investigate the response of groundnut varieties as affected by intra-row spacing and irrigation interval on growth and yield at Teaching and Research Farm of Federal University Dutsin-Ma and Kugado site. Treatments consisted of three varieties of groundnut (SAMNUT 24, SAMNUT 25 and SAMNUT 26), 3 intra-row spacing (15, 20 and 25cm) and three irrigation intervals (3, 6 and 9days). The treatments were factorized and laid out in a randomized complete block design (RCBD) replicated three times. Results from the study revealed that groundnut variety had significant (P≤0.05) effect on growth and yield parameters at the two locations. SAMNUT 24 significantly (P≤0.05) outperformed SAMNUT 26 and SAMNUT 25 respectively in terms of number of leaves per plant, number of days to 50% flowering and kernel weight of (14.87 and 10.67 g) per plant at the two locations. Intra-row spacing of 15cm significantly (P≤0.05) outperformed 20 and 25cm on days to 50% flowering, number of leaves at 3 WAS at Kugado and kernel yield of (11.3 g) per plant at Badole . Irrigation interval of 6days on Kernel weight of (14.69 and 11.10 g) per plant recorded a significant (P≤0.05) effect at the two locations. However, 3days irrigation interval of (46.93 g) also recorded a significant effect on total dry matter at Badole . The study revealed that SAMNUT 24, intra-row spacing of 15cm, and 3days on yield parameters at Badole a nd 6days irrigation interval at Kugado proved to be most appropriate .

Multiple environment trials (MET) are generally carried out by plant breeders to select and recommend high yielding and stable genotypes for a set of environments. The analysis of MET data often results in genotype-byenvironment interactions which often causes difficulties in the interpretation of results and reduce efficiency in selecting the best genotypes. AMMI and GGE biplot analysis are two recent methods that are widely used to overcome these difficulties in MET data analysis. The objective of this study was to compare GGE biplot and AMMI analysis that determine the most efficient method for evaluating and describing genotype performance across environments. Ten (10) cassava (Manihot esculenta) genotypes including two local checks were evaluated across six (6) environments in Southern Ghana. The experimental layout was a randomized complete block design with three replications. The Additive Main Effects and Multiplicative Interaction (AMMI) analysis of variance identified highly significant effects for environment, genotype and genotype by environment interaction denoting different responses of genotypes across environments. The AMMI1 biplot identified AR14-10, CR42-4 and CR59-4 as the most stable genotypes but could not accurately display the performance of a given genotype in a given environment. However, the GGE biplot provided more information with regards to environments and genotype performance than the AMMI1 biplot analysis and was able to identify the environment PK08 as being the most representative and desirable of all.
