Abstract
Two field experiments were conducted at the Experimental farm of Sids Research Station, ARC, In Beni Sulef Governorate, during 2001 and 2002 summer seasons. The experiments included three winter preceding crops (faba bean, berseem and wheat) and three hill spaces (20, 25 and 30 cm) as well as four fertilizer treatments. i.e. (70 kg N/fed, microbin (1g/ 100 gm seeds) + 70 kg N/led, 105 kg N/fed and microbin + 105 kg N/fed. The main results of this work could be summarized as follows: The preceding faba bean gave the greatest effect on growth characters as well as yield and its components followed by berseem and wheat. Regarding hill spacing, decreasing distance to 20 cm increased the values of plant height, ear height and barren plants. Increasing distance to 30 cm between hills gave higher values of leaf area of topmost ear, stem diameter and prolific plants and also yield components of ear weight, ear length, ear diameter, number of grains/row, weight of grains /ear and shelling percentage. The 25 cm between hills increased maize yield than the other treatments. Concerning nitrogen and bio fertilizers the highest values of growth characters, agronomic traits and yield were obtained with microbin + 105 kg N/fed, while the lowest values were recorded with 70 kg N/led. The interaction between preceding crops and bio N levels indicated that faba bean with microbin + 105 kg N/fed gave the highest values of maize grain yield, whereas the lowest values were recorded with wheat and 70 kg N/fed. The interaction of hill spaces with bio-N fertilizer showed that the highest values were obtained with 25 cm hill space and microbin + 105 kg N/fed for maize grain yield. The interaction of hill spaces with preceding crops showed that the highest values recorded with 25 cm hill space and faba bean. As for interaction effects among preceding crops with hill spaces and bio- N fertilizer, the results indicated that legume crops with 25 cm apart and bio + 105 kg N fertilizer gave the highest grains yield. It could be stated that planting maize at 25 cm between hills and applied microbin + 105 kg Med and followed legume crops could be recommended for growing maize (S.C10) under the conditions of Sids district.
