Abstract
The Present study was conducted at Tag EL - Ezz Agricultural Research Station, Dakahlia Governorate, during 2000 and 2001 seasons to study the effect of some preceding winter crops, i.e. faba bean, wheat, and sugar beet, nitrogen fertilizer levels i.e. 60,90,120 and 150 kg N / fad. and phosphorus fertilizer levels i.e. 0, 15 and 30 kg P2O5 / fad. on growth, yield and its attributes of maize (cv. S.C.10). A split plot design with four replications was used .The main results could be summarized as follows: Preceding winter crops had significant effects on plant height, stem diameter, ear length, ear diameter, number of rows/ear, number of grains / row, grains yield / plant, 100-grain weight, plants carried two ears percentage, shelling percentage and grain yield ardab /fad in both seasons. Aforementioned traits were superior when maize was grown after faba bean. The results indicated that increasing fertilizer nitrogen levels from 60 to 150 kg N/fad recorded significantly increase in all studied characters in both seasons. Raising phosphorous fertilizer levels up to 30 kg P2O5/fad resulted in a significant increase in all studied characters in both seasons, except number of grains/row in the first season. The interaction between preceding winter crops and nitrogen fertilizer levels indicated that faba bean as previous crop with 150 kg N/fad gave the highest values of maize grain yield in both seasons. The interaction of nitrogen with phosphorus fertilizer levels showed that the highest values of grain yield /plant of maize were obtained with 150 kg N/fad and 30 kg P2O5 /fad in both seasons. Generally it could be concluded that cultivation of maize after faba been and fertilized by 150 kg N/ fad and 30 kg P2O5/fad could be the best treatments for raising maize production under the conditions of Tag EL -EZZ district according the results of this investigation.
