The Effect of the Combined Chemical, Bio and Vermicomposting Fertilizers on Yield and Yield Components of Vicia Faba L.

Abstract

In order to evaluate the effect of combined of chemical, bio and vermicomposting fertilizers on faba bean yield in Gilan province, a factorial experiment in a randomized complete block design with three replications was conducted in the city of Rasht in 2013. Treatments nitrogen fertilizer in three levels (zero, 50 and 100 kg per hectare), phosphorus fertilizer in three levels (zero, 50 and 100 kg per hectare), bio-fertilizer combination of Bacillus and Pseudomonas and without application of vermicomposting with two levels including Zero and 7 tons per hectare were considered for the study. The results showed that grain protein percentage was significantly affected by the interaction of nitrogen fertilizers × phosphor × vermicomposting× organic fertilizer and other traits affected by the interaction of biological nitrogen ×fertilizer × phosphorus and nitrogen. Means comparison showed that 100 kg of nitrogen per hectare, 100 kg phosphorus with the use of bio-fertilizer and vermicomposting increased grain yield and yield components. The  seed yield of 100 kg N ha interaction was the highest in 100 kg of phosphorus per hectare (6243 kg/h) and the lowest in control (507 kg/h). Also, in interaction at phosphorus fertilizer bio-fertilizer, the seed yield of 100 kg of phosphorus by using bio-fertilizer (5497 kg/h) was observed and the interaction N × vermicomposting was observed at the highest grain yield at 100 kg nitrogen by the use of vermicomposting (5455 kg/h). The highest amounts of protein in treatment were in 100 kg N, 100 kg of phosphorus fertilizer with organic fertilizer usage and application of vermicomposting 7 tons per hectare (31.43 percent). In general, the results can be expected that the use of bio-fertilizers and vermicomposting can provide part of the required plant food.
