    Growth and yield of maize as affected by fertilizer types in the Southern Guinea Savannah, Nigeria
    (2018) Afe, A.I.; Fasakin, K.; Ogunbosoye, D. O; Kolade, U.
    A field trial was carried out at the Teaching and Research Farm, Kwara State University, Malete, in the 2017 cropping season to investigate the growth and yield of maize as affected by fertilizer types. The five fertilizers tested were four organic-based fertilizers (KOBF-1, KOBF-2, Aleshinloye Grade A, and poultry manure), inorganic NPK fertilizer, and the control without soil amendment. The fertilizers, except poultry manure, were applied at the rates of 100 kgN/ha and the treatments arranged in a Randomized Complete Block Design (RCBD) with three replicates. Application of poultry manure, which was applied at 10 t/ha, was found to be superior compared to all other treatments in all the parameters measured. The three formulated organic-based fertilizers were Aleshinloye Grade A (a commercially available fertilizer formulated with household wastes and cow dung), KOBF-1 and KOBF-2 (Kwara Organic-Based Fertilizers in development by Kwara State University and formulated with poultry manure and tithonia plants). Aleshinloye Grade A produced inferior growth and yield and yield components of maize compared to the other organic-based fertilizers. The control took a significantly longer number of days to tasseling and silking (62 and 68 days, respectively) compared to the other treatments. The results indicated that, in terms of overall grain yield in kg/ha, poultry manure produced the highest yield (4,633 kg/ha), followed by the inorganic fertilizer (4,096 kg/ha), then KOBF-1 and KOBF-2 with similar values (3,163 and 2,923 kg/ha, respectively), followed by Aleshinloye Grade A (2,160.00 kg/ha). The control treatment gave the least grain yield (1,148.20 kg/ha). The organic fertilizers tested all proved to be effective in raising yields. Organic fertilisers have known ecological and environmental benefits and are recommended for inclusion in the development of national fertilizer programmes for sustainable crop production.

    GROWTH AND YIELD RESPONSES OF SESAME AND SORGHUM IN SESAME/SORGHUM INTERCROPPING
    (Nigerian Journal of Crop Science, 2022-05) Afe, A.I.; Alabi, K.O.; Wahab, A.A; Oladipo, S.F.
    A field trial was carried out at the Kwara State University Teaching and Research farm in the 2019 cropping season. The study aimed to investigate the growth and yield responses of sesame as sorghum as affected by varying Population density of both crops. Seven population densities viz: 100%SE:100%SH, 100%SE:75%SH, 100%SE:50%SH, 100%SE:25%SH, 75%SE:100%SH, 50%SE:100%SH, and 25%SE:100%SH plant population per hectare where SE and SH represented sesame and sorghum respectively were combined in a Randomised Complete Block Design (RCBD) and replicate three times. The full population of each crop 111,111 and 55,555 plants per hectare respectively for sesame and sorghum were also included in the treatment as a control. The height and grain Yield of sorghum were significantly influenced by population density of component sesame. The height decreased as the population density of component sesame decreased. The seed yield of sesame was affected by population density of component sorghum with the lowest yield (115,19 kg/ha) obtained at 100 SH:25SE population ratio. Reasonable intercropping advantage was observed at the treatments where 55,555 and 41,250 population density of sorghum was intercropped with 111,111 plant population of sesame as measured by the land equivalent ratios (LER) and Land equivalent Coefficient (LEC) indices. Intercropping sorghum at population density of 27,777 and 13,750 with sesame at population density of 111,111 plants per hectare was disadvantageous. Aggressivity (A) values were positive for sorghum and negative for sesame in all population ratios tested except, 50SH:100SE and 25SH:100SE population ratios. The competitive ratio (CR) values followed a similar trend to the A values. The highest A value, 0.70 and -0.86, and CR, 18.2 and 4.20 respectively for sorghum and sesame were recorded at 100SH:25SE population ratios. A reasonable intercropping advantage was obtained at the treatment where the full population ratio of both was intercropped and hence, recommended for adoption.
