Yield and Yield Components of Vetch (Vigna radiata) as Affected by the Use of Vermicompost and Phosphate Bio-fertilizer

To evaluate the effects different levels of phosphate biofertilizer barvar-2 and vermi compost on yield and yield components of vetch plant (Vigna radiata L.)in Yasouj a factorial experiments was performed in completely randomized design in crop year of 2013. Experimental treatments were phosphate biofertilizer barvar-2 at 3 levels (0, 50, 100 gram per hectare) and vermicompost at 4 levels (0, 10, 20, 30 ton per hectare). In this study stem height, root length, biological yield, seed yield and harvest index was measured. ANOVA and comparison of means showed that vermicompost significantly increased stem height, economic and biological yields. Results, also, indicated that highest yield and biomass, 4.3 and 18.8 g/plant, observed respectively when 100 g/ha of barvar-2 and 30 t/ha of vermi compost were used. Using both of phosphate biofertilizer barvar-2 and vermicompost was better than their individnal usage. This indicates that combined use of these 2 factors would produce higher yield. It can be concluded that application of 100 g/ha of barvar-2 and 30 t/ha of vermicompost would a proper recommendation.
