Abstract

In order to investigate the effects of IRRIGATION levels and NITROGEN fertilizer on seed yield, seed PROTEIN and vegetative traits of Sahar cultivar of SOYBEAN, an experiment was arranged as split plot based on randomized complete block design with four replications in khanbebin, Golestan Province during summer of 2010. Treatments were IRRIGATION management (7, 14 and 21 days) and NITROGEN application (0, 35, 70, and 105 kg per hectare) in growth stages. NITROGEN was used in vegetative stages (with first IRRIGATION of all plots) and reproductive stage (with IRRIGATION of all plots). Results showed that plant height and PROTEIN yield of seeds (a=1%) and below pod height, number of nodes per plant and PROTEIN percentage of seeds (a=5%) were affected by IRRIGATION management. The highest pod height and number of branches per plant were not affected by IRRIGATION management. Effect of NITROGEN amounts on plant height, lowest pod height, number of nodes per plant, number of branches per plant, PROTEIN percentage of seeds and PROTEIN yield of seeds were affected by NITROGEN application (a=1%). Interaction between IRRIGATION management and NITROGEN application was not significant. Plant height and lowest pod height in 7-day IRRIGATION with 79.71 and 77.23 cm were higher than the others. Number of nodes per plant in 14-day IRRIGATION with 34.52 was higher than the others. Maximum PROTEIN percentage belonged to 21-day IRRIGATION (40.72 %). The highest and the lowest PROTEIN yield with 1723 and 1424 kg/ha were obtained from 14 and 21 days IRRIGATION. Minimum seed yield, plant height, the lowest and the highest pod height, number of nodes per plant, number of branches per plant, PROTEIN percentage and PROTEIN yield with 3368, 70.64 cm, 13.54 cm, 68.18cm, 28.83, 6.156, 36.38% and 1223 kg/ha belonged to 0 kg N and maximum was obtained from 105 kg N with 77.06 cm, 14.6 cm, 76.4 cm, 35.7, 7.513, 41.51% and 1835 kg/ha respectively.
