Evalution of yield and yield components of lentil (Lens culinaris Medik.) effected by biofertilizer, nitrogen starter and supplemental irrigation in Kermanshah province

In order to evaluation of yeild and grain yield components Lentil (Lens culinarisMedik.) affected by biofertilizer¡ nitrogen starter fertilizer and supplementary irrigation in the Gilangharb Region of Kemanshahan province an experiment was conducted in 2014-2015 as form split split plot based on randomized complete block design with three replications. In this experiment¡ supplementary irrigation factor as a main plot consist three levels:Non irrigation (rainfed)¡ irrigation during seed filling stage and irrigation during poding stage¡ biofertilizer factor as a sub plot include two level: Use and not-use biofertilizer¡ and nitrogen starter fertilizer factor as a sub sub plot consist four level: non-use (control)¡ use base on 33¡ 66 and 100 persentage of need plant. The results showed that the main effect¡ double and triple interaction effects of experimental factors (irrigation¡ bio-fertilizer¡ nitrogen starter fertilizer)¡ with the exception of 1000-seed weight was significant on all traits. According to the results obtained in this experiment¡ the use of bio-fertilizer along with supplemental irrigation at grain filling stage and nitrogen fertilizer Soils consumption 66% by 2390 kg per hectare grain yield was obtained the great yield. Because¡ this combine treatment was superior in terms of grain yield components compared with other treatments. In the combine treatment of no irrigation¡ no fertilizer and no fertilizer nitrogen starter fertilizer also was obtained 1025 kg per hectare the grain yield¡ that has been reduced 57% compared to the previous treatment combination. Generally 66% of nitrogen fertilizer of need plant and consumption of bio-fertilizer increased grain yield.
