Abstract:
preliminary trial was conducted at the University of Benin Teaching and Research Farm to determine the response of lead plant Leucaena leucocephala (Lam) de Wit) seedlings to different levels of Mo in a completely randomized design replicated 3 times. The levels of Mo include 0, 50, 100, 150 200 mgMo per 10 kg soil. Results showed that the number of nodules, number of leaves, plant height, stem girth, shoot and root dry matter yield increased with increasing Mo treatments with the 200 mgMo significantly exceeding other treatments including control at final harvest. The soil nutrient components after the trial revealed that there were no consistencies in K, Na, Mg, Ca, organic carbon, ECEC, with increasing Mo treatments. The P and Mo components of the soil however, decreased with increasing Mo application while N and exchangeable acidity content increased with increasing Mo application. The soil pH was fairly constant after the trial and generally, there was an improvement in the nutrient components of the soil after the trial compared to pre-trial nutrient content.
