Abstract
The objective of the present study is to investigate the effect of three spaces between plants of 15, 20 and 25 cm and three nitrogen forms of (NH4)2 SO4 20% N, NH4NO3 33% N and urea ammonium nitrate liquid (UAN) 32% N on broad bean var. Kassasen 1 growth, yield, protein and nitrate accumulation. Two field experiments were conducted at Disuq district Kafr El-Sheikh Governorate during the two successive winter seasons of 2004/2005 and 2005/2006. The results could be summarized as the following:
1. Wider space (25 cm) between plants had the highest vegetative growth i.e., number of leaves plant‑1, number of branches and leaf area plant-1, as well as the highest number of pods plant-1, green pods weight and green pods plant-1. On the other hand, the narrow spaces (15 cm) had the highest green pods weight fed.-1 and the lowest nitrate, phosphorus %, total nitrogen % and total protein %.
2. Urea ammonium nitrate had the highest vegetative traits parameter while the lowest values were recorded with ammonium sulphate form. Also, the highest yield and yield components values were obtained with urea ammonium nitrate in both seasons. The lowest nitrate accumulation in the green pods and dry seed samples were obtained with (NH4)2 SO4 in both seasons. The highest phosphorus % values were observed with (NH4)2 SO4 in both seasons while the highest protein % values were recorded with UAN forms.
