Effect of K Nano-fertilizer and N Bio-fertilizer on yield and yield components of red bean (phaseolus vulgaris L.)

摘要

A field experiment was laid out in order to study on effect of Nano and Bio fertilizers on yield and yieldcomponents of red bean (pheseolus vulgaris L.) in Islamic Azad University, Boroujerd branch, Iran at 2014. Theexperiment was laid out in a factorial design based on randomized block design with three replications.Treatments were Nitrogen bio-fertilizers in four levels (Azot Barvar 1, Nitrokara, Nitroxin and control) with 27%Khazraa K chelate Nano-fertilizer (KKCNF) in four levels ( foliar 1, 2 and 3 in 1000 and control). Analysis ofvariance results showed that effect of N-biofertilizer and KKCNF treatments on yield and all yield componentswere significant at 1% probability level. Interaction effect of them was significant on all treats except number ofgrain per pod. According to the mean comparison charts, higher number of grain per pod , 1000 grain weight,biomass yield and grain yield for N bio-fertilizer found in Azot Barvar 1 and the control treatment had the lowestof them. For foliar application of KKCNF comparison of the mean values of them obtained at 2 in 1000 solutionand control treatment had the lowest. Interaction effect between N bio-fertilizer and KKCNF showed thatcombined application of Azot Barvar 1 and 2 in 1000 solution had the highest of the above treats and the controlcombined treatment had the lowest. In final our results indicated that yield and yield components of red beanincreased with application of N bio-fertilizer and KKCNF and could be replaced chemical fertilizers by thesefertilizers.
