بررسی عملکرد سویا در تاریخ کاشت های مختلف و کود بیولوژیک بارور2

In order to evaluate the Effect of planting dates and Barvar2 biological fertilizer on soybean yield, an experiment as carried out in factorial experiments based on a randomized complete block design with 3 replications in Hamden climate. The first factor was sowing date in 3 levels (8th June, 17th June and 29th June) and the second factor was fertilizer in 3 levels (control= without fertilizer, Barvar2=100 g/ha and Triple phosphate= 100 kg/ha). Results showed that sowing date had significant effect on seed weight in plant, number of pod per plant in 1/3 low, number of pod per plant in 1/3 mid, number of pod per plant in 1/3 up and seed yield in 1% level. Also, fertilizer treatment had significant effect on seed weight in plant and number of pod per plant in 1/3 mid. The highest yield related to sowing dates in 8th June and 17th June (5503.4 and 5092.8 kg/ha, respectively). Sowing date× fertilizer interaction had significant effect on seed weight in plant and number of pod per plant in 1/3 mid. Seed weight increased seed yield, while increasing in number of pod per plant reduced seed yield.
