Effect of FYM and Phosphorus Fertilization on Yield and its Components of Maize

A.E.A. Omar

In order to maximize the productivity of maize several investigators indicated the need of maximizing the use of mineral and organic fertilizers. Therefore, this investigation was conducted for two summer seasons (2010 and 2011) in the Experimental Farm of the Faculty of Agriculture (Gazala site), Zagazig University, Egypt. The study aimed at finding out the response of maize yield and its components to five levels of P fertilization (0, 20, 40, 60 and 80 kg P2O5 ha-1) and three rates of FYM (0, 40 and 80 m3 ha-1). A randomized complete block design of four replicates was used where planting was made in hills 25 cm apart in ridge 70 cm apart and one plant was left per hill after thinning (21 days after planting). The results indicated the response of maize grain yield ha-1 to the increase of P level up to 60 kg P2O5 ha-1. This response was expressed in plant height, number of grains row-1, 100-grain weight and hence the grain weight ear-1. Neither the number of rows ear-1 or shelling percentage was affected by P addition. Similar positive effect was observed due to addition of FYM on the aforementioned yield components and hence the final grain yield ha-1 up to the addition of 80 m3 ha-1. These two factors acted independently where their interaction did not affect the grain yield ha-1 and almost all grain yield attributes. The response equation of grain yield ha-1 indicated a diminishing increase with increase of P level up to 80 kg P2O5 ha-1 and FYM rate up to 80 m3 ha-1.
