The Effect of Chemical and Biofertilizers on Yield and Yield Components of Pea (Pisum sativum L.) as Second Crop

Effect of chemical and biofertilizers on yield and yield components of pea cultivar ARROW was studied. This trial was conducted in 2009 in a randomized complete block (RCBD) design with three replication and 8 treatments at Islamic Azad University, Tabriz branch. The 8 treatments was: 1) control, 2)Yashil application, 3)inoculation of the seeds with Nitragin, 4) inoculation of the seeds with Biosuper, 5) inoculation with Nitragin Yashil application, 6) inoculation with Biosuper Yashil application, 7) inoculation with Nitragin Biosuper, 8) inoculation with Nitragin Biosuper and application of Yashil. Highest fresh yield was obtained (391.5 gr/m2 )from the 8th treatment, and least yield from the control (275.5gm-2).In other characters under study like biomass highest yield was obtained by application of Yashil with Biosuper inoculation(3341.1g/m2) heaviest hundered seed weight obtained by Yashil application of Biosuper and Nitragin inoculation (64.7g), highest seed number per pod (8) produced by Nitragin inoculation with Yashil application, highest seed number per plant resulted from Nitragin, Biosuper inoculation and Yashil application (30.9), heaviest seed weight per pod and plant were obtained by Biosuper and Nitragin Yashil inoculation (5.74g and 19.6g) respectively. Based on of the result, it seems that application of biofertilizers would increase the yield and yield components of green pea and if it is accompanied with macro- and micro nutrients the effect would be higher.
