    EFFECTS OF MAIZE – COWPEA INTERCROPPING PATTERNS ON YIELD AND PROPERTIES OF TYPIC PLINTHUSTALFS SOIL IN SOUTH GUINEA SAVANNA ZONE, NIGERIA
    (Ghana Journal of Science, 2024-04-08) Alabi, K.O; Afe, A.I.; Adewumi, A.O
    One of the factors preventing Nigeria’s agriculture from being more productive is its low soil fertility. Adoption of maize-cowpea intercropping system is being promoted as one of the options for improving soil fertility. A field experiment was carried out at Kwara State University Teaching and Research Farm in 2018 cropping season to assess the effect of maizecowpea intercropping patterns on yield and soil properties. The experiment was laid out in a 2×4 factorial split plot arrangement in a Randomized Complete Block Design. The spatial row arrangement was the main block while population density was assigned to subplot. The yields and physical-chemical properties of soils were examined after all crops were harvested. Sole crop of both maize and cowpea was found to be significantly higher in yield parameters than their intercrops. Intercropping had no significant influence on textural class, bulk density and saturated hydraulic capacity of the soil. Soil total Nitrogen content was slightly increased in 2:2 spatial arrangements except in 100M: 25C and sole cowpea compared to initial total nitrogen. Soil organic matter at the intercrop increased as the population increased in 1: 1 arrangement whereas, the value was not consistent in 2:2 row arrangement. Population density of (100M:100C) which produced (2151.94 for maize and 1813.64 kg/ha for cowpea) and 1:1 row spatial arrangement with superior Land Equivalent Ratio (LER) value can be recommended to the farmer. Also integrated fertility management strategy other than only intercropping should be advocated

    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 of Tomato (Solanum lycopersicum) Cultivars as Affected by Hydroponic Nutrient Solutions
    (Horticultural Society of Nigeria (HORTSON), 2024-12-23) Afe, A.I.; Alhaji, A.B.; Abdullahi, M.N.; Awoniyi, A.O.; Abdulkareem, M.O.
    A study was carried out at the Kwara State University Teaching and Research Farm, between February and June 2024 to investigate the growth and fruit yield of tomato cultivars (Diva F1 and Rio grande) under different hydroponic solutions (Bic liquid and Bic granule). The experiment was laid out in a completely randomized design and replicated three times. The pH of the nutrient solution during the study ranges between 6.4 -6.7, while the EC ranges between 2.10 dSm-1 – 3.02 dSm-1.Except at 2WAT, the hydroponic solution in a liquid form significantly had fewer leaves than the granular nutrient solution in the Diva F1 tomato cultivar. The tomato cultivar under the granular solution took more days to attain flowering and fruiting than the liquid solution. Similarly, Diva F1 significantly attained flowering and fruiting earlier than the Rio Grande. Under the two nutrient solutions, the highest fruit yield in the Diva F1 was obtained in the granular nutrient solution whereas the higher fruit yield from the Rio grande cultivar was recorded in a liquid nutrient solution. In general, highest fruit yield was obtained from the Rio grande under granular nutrient solution. Rio grande under granular Bic solution is therefore recommended for growers in hydroponic system.

    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.

    Growth, Yield and Competitive Indices of Cowpea and Sorghum in Sole and Intercropped System
    (NCRI Press, 2023) Afe, A.I.; Nuruden, K.; Yaman, U
    The need to increase cowpea production to solve the menace of malnutrition is a global challenge and land limitations have also made intercropping indispensable. Field trials were carried out at the Teaching and Research Farm, Kwara State University, Malete, and National Centre for Agricultural Mechanization (NCAM) Idofian to evaluate the growth and yield of cowpea cultivars and sorghum with their competitive behavior in cowpea-sorghum intercropping. Five cultivars of cowpea (IITA-256, IITA-277, VITAL-5, IT98K-491-4, and IITA-288) were intercropped with sorghum (SAMSORG47-SKV8). Sole crops were included in the treatments as a check. The treatments were arranged in a Randomized Complete Block Design and replicated three times. Among the sole, vital-5 cultivar had the highest number of branches and pods per plant with the highest grain yield of 591.30 kg/ha and 530.00 kg/ha respectively, in Malete and NCAM. At the intercrop, IITA-288 significantly had the least number of branches per plant and took longer days to attain flowering compared to other cultivars. Regardless of location, the lowest grain yield at the intercrop was also obtained with this cultivar. Sorghum intercropped with cowpea cultivar IITA-288 was at par with the sole sorghum in all the parameters. The least grain yield of sorghum at the intercrop was obtained in sorghum intercropping with IITA-256 cowpea cultivar. The maximum Land Equivalent Ratio (LER), and Land Equivalent Coefficient (LEC), was obtained with the Vital-5 cultivar. Regardless of location, the competitive ratio (CR) values for IITA-256, IITA-277, and Vital-5 cowpea cultivars were higher than sorghum. The aggressivisity, (A) for these cultivars were also positive for cowpea and negative for sorghum. Although, all the cowpea cultivars demonstrated intercropping advantages in efficient utilization of natural resources intercropping sorghum with the Vital-5 cowpea cultivar was superior and could be adopted by the farmer
