To determine plant density along with proper nutrition, two new lines of soybean, namely 2001 and 2002 with the objective of optimum utilization more than farmland and grain yield of soybean per unit area in two separate trials in 1391 for two years, were studied. The project consumed three levels of potassium and magnesium potassium sulphate 0, 100 and 200 kg/ha and two levels of magnesium sulphate including 0 and 200 kg/ha as the main factor (in form factorial) and the distance between rows 30, 40 and 50 cm with the density of 40, 50 and 66 plants per square meter as subplots in a split-plot experiment based on randomized complete block design with four replications was conducted. The highest yield of 4695 kg per hectare was gained in density of 30 plants per square meter and was classified as A group. The highest seed weight was related the 200 kg/ha of potassium and magnesium intake of 100 kg/ha, respectively. In line2002 potassium treatments had significant effect on grain yield and number of pods, seed yield and seed weight as well as the use of magnesium and plant density had significant effects at 1% probability level on grain yield, grain weight and number. The highest grain yield (4570 kg/ha) was related to density of 30 plants per square meter and was classified as A group. The interaction of two factors related to the treatment 0 and 100 kg/ha of potassium and 100 kg/ha of magnesium had high amount of grain yield and grain weight, which in class A and AB respectively
