مقایسه کودهای معدنی آلی شرکت بویسکی روسیه با کودهای شیمیایی معمول بر عملکرد سویا

The present research work was carried out in a randomized complete block design with 3 replications and 10 different fertilizer treatments including some organo-mineral fertilizers from Russian company of Buisky in compare with traditional chemical fertilizers, during 2013 in Hashemabad Cotton Research Station on Katool soybean cultivar, to compare the different sources of fertilizers and determine the best fertilizer treatment on soybean yield. Analysis of variance showed a significant difference between treatments in terms of soybean yield. The treatment which was containing both organo-mineral and chemical fertilizers with 4784 kg/ha had the highest yield and placed in the first group. The treatment involving the use of all organo-mineral fertilizers of Buisky (Aquamix, Universal, Aquarin5 and Aquarin13) based on their recommendation, although with 4669 kg/ha had 2.5 percent less than the previous treatment, but according to consume less fertilizer, it seems to be more appropriate treatment because of the lower cost of fertilizers. This treatment could increase soybean yield as much as 13.5% in compare with the control, and therefore, it was considered as the best treatment.
