Abstract
A field experiment was conducted to evaluate the performance of three genotypes of soybean Iman, Taqa and Lee74 planted on lines with three different spacing 40, 50 and 60 cm and two plant spacings on each row 5 and 10 cm. The experiment was carried out according to the randomize complete block design as a factorial experiment with three replicates to study the number of nodes on the main stem, length of internodes, weight of pods.plant−1, pod weight, number of seeds.plant−1, seed weight.pod−1, weight 1000 seed, seed net weight, seed yield g.plant−1, oil yield, and protein yield. The results showed significant differences between the studied factors of the distances between and within lines, genotypes double interaction and triple interactions in all the studied traits except length of inter nodes (cm) of the genotypes as well as of the double interaction intra row spacing * genotypes. The genotype Iman was superior to the seed yield 41.93 g.plant−1 and distance 60 cm in seed yield 50.62 g.plant−1and the distance 10 cm between the plants in the seed yield 43.48 g.plant−1.
