摘要

Nutrient management is one of the most important factors in successful cultivation of plants. Biofertilizers can affect the quality and quantity of crop.?In order to study the effects of biofertilizers on grain yield and protein content of two soybean?(Glycine max L.) cultivars, an experiment was conducted using a factorial arrangement based on randomized complete block design with four replications, at the Mahidasht Research Station of Kermanshah in 2010. The factors were soybean cultivar (Williams and Line no. 17) and fertilizer application (b1= N + P, b2=?Bradyrhizobium japonicum?+?P, b3=N?+?Bacillus?and?Pseudomonas?+ 50% of P, b4=?B. japonicum?+?Bacillus?andPseudomonas?+ 50% of P,?b5=?B. japonicum?+ 50% of?N?+?Bacillus?andPseudomonas?+ 50% of P).?Results show that Line no. 17 with 2911.2 kg/ha had higher seed yield than Williams with 2711 kg/ha. Also, fertilizer levels of b3?with 3058.2 and b2?with 2643.8 kg/ha produced the highest and the lowest seed yield, respectively.?Plants?treated?with?fertilizer?levels of b1, b2?and?b5?in comparison?with other?fertilizer?levels?significantly?produced?lower?thousand seed weight. In Line?no.?17fertilizer?level of b3?with 2.88 produced the highest seed per pod. Results show that fertilizer levels had a significant effect on the number of pod per plant and treatments containing?biological?fertilizers?in terms of the number?of pods?per plant?were?equal?orsuperior?to chemical?fertilizer.?It was also observed that fertilizer levels of b1, b3?and b5, produced the highest protein percentage.?It therefore seems that biofertilizers can be considered as a replacement for part of chemical fertilizers in soybean production.
