    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

    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.

    YIELD AND GROWTH RESPONSE OF SWEET CORN (Zea mays saccharata) TO WATER STRESS REGIMES ON A LOAMY SAND SOIL
    (www.nexusjournals.com: JOURNAL OF NATURAL AND APPLIED SCIENCES, 2016-04-18) Wahab Adesina Abudlkabir; Oluwasemire Kolapo Olatunji; Oshunsanya Suarau Odutola; Hamza Abdulmajeed
    Maize dry season production is often confronted with soil moisture, pest diversity and environmental stress that becomes obvious in plant stress. Therefore, the amount of stress that a plant can withstand depends on soil type and evapo-transpiration demand of the atmosphere. Thus an experiment was carried out to assess the effects of varying levels of water stress on the growth and yield of sweet corn on a loamy-sand soil. For this purpose, Crop-Environmental Water Demand (CEWD) was developed from daily evapo-transpiration records and FAO crop water requirements for different stages of maize growth, based on the average weather data for a decade (2001 - 2011). Soil requirement for growing maize in the area was also noted. A tropically adapted sweet corn population was grown under four water application rates ranging from 25 % to 100 % CEWD in a randomized complete block design with three replicates. The results showed that there was a significant difference in plant growth for the four treatments imposed as the increase in soil moisture level influences plant development. Differences among the treatments number of grains per plant were significant. Sweet corn grain yield was in the order of 75 % > 100 % > 50 % > 25 % CEWD. Significant differences were not observed for flowerings dates and number of leaves. Mean plant height was closely related to the rate of water application and ranged from 0.65m - 1.2m across the treatments. Seventy-five percent CEWD treatment plots had the highest total dry matter content and leaf area index, which explains the significant differences observed in the grain yield. Application of 75 % CEWD on sweet corn significantly influenced the growth and yield of sweet corn on loamy-sand soil. Water application rates at 25 % less full CEWD was adequate for dry season sweet com production on loamy-sand soil in Ibadan, Nigeria.
