Growth, Yield and Nutrient Concentrations of Tomato as Affected by Soil Textures and Nitrogen

E.Y. Oyinlola and S.A. Jinadu    

Abstract: Sand, loam and clay are three main textural classes of soil. However, they differ in their nutrient and water holding capacities. A greenhouse experiment was conducted to determine the effect of five rates of N fertilizer (0, 30, 60, 90, 120 kg N ha-1) grown in 3 different textural classes (sand, loam and clay) of soil on growth, yield and nutrient composition of tomato. Effects of N on all the parameters determined were significant (p≤0.05) except plant height at 2 and 4 Weeks after Planting (WAP). The highest plant height at harvest (12 WAP), mean fruit weight, fruit yield and dry matter yield were obtained at 90 kg N ha-1. Tissue nutrient (NPK) concentrations increased as the rate of N increased. Loam soil produced the highest value of all the parameters determined except tissue N concentration. Tomato growth and yield were significantly influenced by soil texture and N applications; loam soil at 90 kg N ha-1 proved superior to other treatments, in this study.
