Abstract:

In order to evaluate of nitrogen efficiency and grain yield of white bean under combined application of organic and biological fertilizers in Niasar region, a factorial experiment based on randomized complete block design with three replications was conducted in 2015. The first factor included four levels of biological fertilizer (control, inoculation with nitroxin, Barvar-2 and nitroxin + Barvar-2) and second factor included four levels of organic fertilizer (control, farmyard manure, mushroom compost and vermicompost). In this study characteristics such as number of grains per plant, weight of 100 grains, grain yield, number of days to maturity, nitrogen percentage, amount of phosphor absorbed by plant and physiological efficiency of nitrogen were assessed. Results showed that the interaction effect of organic and bio-fertilizers was significant on number of grains per plant, grain yield, number of days to maturity, nitrogen percentage, amount of phosphor absorbed by plant and efficiency of nitrogen. The maximum nitrogen efficiency (0.25 kg.kg-1) was obtained by inoculation with Azotobacter + farmyard manure and the minimum of nitrogen efficiency (0kg.kg-1) by control+control. The maximum of grain yield (3083 kg.ha-1) were obtained by vermicompost and the minimum of grain yield (2524 kg.ha-1) by control treatment. Therefore, the combined application of organic and biological fertilizers, could improve the quantitative and qualitative traits of the Bean.
