    Background: This study examines the impact of water stress on sweet corn (Zea mays saccharata) growth and yields in loamy sand soil, Ilorin. It aims to elucidate the relationship between water stress and crop performance while identifying optimal water requirements for enhancing sweet corn development in this soil type. Methods: The study employed a randomized complete block design (RCBD) with three replicates, featuring four crop-environmental water demand (CEWD) treatments: 100%, 75%, 50% and 25% CEWD. Water application rates (90 litres per plot every 2 days) were calculated using 12 years of meteorological data (2011-2022) for Ilorin, based on FAO crop water needs and daily evapotranspiration. Sweet corn seeds (Ex-IITA) were planted at 75 cm by 25 cm spacing. Key parameters measured included plant height, leaf count, leaf area index, biomass, days to 50% flowering, grain count and yield. Statistical analysis was conducted using Genstat 17th edition. Result: Increased soil moisture significantly impacted plant development, with notable variations in growth rates across the four treatments. Sweet corn grain yield followed the order: 75% > 100% > 50% > 25% CEWD. No significant differences were found in flowering dates or leaf count. Mean plant height ranged from 0.627 m to 0.975 m, correlating with water application rates. The 75% CEWD treatment resulted in the highest total dry matter content and leaf area index, explaining its superior yield. The 75% CEWD level is optimal for sweet corn cultivation in Ilorin, loamy sand soil, Nigeria, promoting sustainable agriculture.

    Mining effluent impact on selected soil physical quality parameters in agricultural land Daba, Kwara State, Nigeria
    (Direct Research Journal of Agriculture and Food Science, 2025-02-22) Wahab Adesina Abudlkabir; Alasinrin Sikiru Yusuf; Abioye Toyeeb Abayomi; Agboola Kola; Aina Oluseyi Abel
    The study examined soils' physical, chemical, and selected soil water transmission properties in an unregistered mining community in Moro Local Government Area, Kwara State, North-Central Nigeria. The assessed agricultural lands based on the reconnaissance survey were 400 m and 800 m away from the mine site, and 1200 m (forested area) away from the mine site. A 25 m x 25 m plot was demarcated and replicated three times in each farmland and mining site. Soil samples were obtained from the 0 to 15 cm soil layer at the 5 m x 5 m subplot level and analysed for particle size distribution, pH, organic C, total N, available P, exchangeable Ca2+, Mg2+, K+ and Na+, total acidity and selected heavy metals (Zn and Cu). Infiltration tests were run using the double-ring infiltrometer. Sixty soil core samples were collected from the study area to determine the water-holding capacity, bulk density, and hydraulic conductivity. The study showed that soil particles at mining sites were loamier and contained a significantly higher concentration of heavy metals but lesser concentrations of some soil nutrients than in the farmlands and the forested areas. The study also revealed that hydraulic conductivity and bulk density trends vary between 400 and 800 m from the mining site but within the recommended range of the soil-water transmission pathway. As a result, the mining effluent seems to have little impact on the water retention capacity of the soil's water transmission system, and plants growing in that region will not suffer a distorted soil water flow.
