Abstract

Abstract: The study aimed at investigating effects of lime and mineral P fertilizers on P uptake and growth of maize ( Zea mays subsp.) in greenhouse pot experiment. Combination of four P rates and four lime rates were applied to four highly acidic soil samples and the soils were incubated for a total of 112 days after which maize ( Zea mays subsp.) was planted. The maize plants were harvested for analysis after 42 days of growth. Control experiments were also included. Available P (Bray I) and pH were significantly increased after incubation. Maximum available P was obtained in the soils that received the highest P rate and optimum lime rate. Levels of exchangeable acidity were significantly decreased in the P and lime treated soils compared to the control experiments. Plant biomasses and P uptake of maize increased significantly (p ≤ 0.001) with application of P and lime compared to the control experiments.
