| Abstract | ||||
| This investigation studied the performance of 4 soybean genotypes (H30, H2F12, H117 and Giza 111) to three sowing dates (1st May, 20th May and 10th June) and also plant dense (105.000, 140.000 and 175.000 plant/fed.) during two summer seasons of 2013 and 2014. The effect of planting dates was important than other factors for flowering date, seeds weight/plant and seeds weight/fed. whereas, the effect of plant dense population was the most important for No. of branches/ plant and plant height. While, the effect of soybean genotypes was the most important for seeds oil percentage. The effect of planting date were more important than other factors for seeds yield (kg/fed.) the highest seeds yield/fed (2240 and 2126 kg) in the first and the second season respectively. Plant density showed high differences in seeds yield/fed. in which 175.000 plant fed. gave higher yield (2215.6 and 2108.6 kg/fed.)in the first and the second season respectively. Soybean genotypes showed high differences in seed yield/fed. in which H111 gave higher yield (2213.3 and 2124.1 kg/fed.) in the first and the second season, respectively, and surpassed all other genotypes. The seed oil and seeds yield/fed. Contents showed opposite magnitudes, planting in 20th May gave higher yield/fed with the lowest oil content (12.3 and 11.5%) in the first and the second season respectively. While planting in 10th June gave lowest yield/fed with higher oil content (18.3 and 16.1%) in the first and the second season respectively. | ||||
