Response of Corn at Different Levels of Nitrogen Fertilizer and Cultivation Distances

Abstract

Abstract Study the response of the corn crop / Bohooth 106 cultivar, at different levels of nitrogen fertilizer (NF) and cultivation distances (CD). were tested under three levels of nitrogen fertilizer NF of 200, 250 and 300 kgN.ha-1, and two levels CD of 15 and CD of 20 cm The split -split plot arrangement in RCBD with three replications was used. The results showed that the NF of 300 kgN.ha-1 was significantly superior to the other two levels of NF of 200 and 250 kgN.ha-1 in all studied conditions. Soil characteristics(SBD and TSP), plant and root parameters (RL, RDFW and PDFW) and yield and plant growth parameters (PVI, PH, LA and GY). The CD of 20 cm was meaningfully best than of CD of 15 cm in all studied conditions.
