تاثیر تاریخ کاشت ومصرف بهینه کود شیمیایی و زیستی کشت بادام زمینی در همدان

In order to assay improved optimal consumption of chemical and biological fertilizers and effect of
planting date on yield and yield components of peanut, This study was conducted by split plot experiment in
randomized complete block design with three replications in 2013. Three Planting data (1 May, 10 May and
20 June) and four levels of Bio-fertilizers consisted of chemical , Bio-fertilizers and control treatments was
considered. Results showed that main effect of planting date and Bio-fertilizers were significant in , number
of seed per pods, number of pods per plant, seed weight, seed yield, biological yield, harvest index at the 1%
level.the intraction effect of planting date and fertilizer on number of pods per plant, seed weight, seed yield,
biological yield, harvest index were significant at the 1% level. Whereas number of seeds per pod was
significant at the 5% level. The planting date 1 may with application of Barvar-2 phosphate fertilizers and
Barvar-1 nitrat fertilizer treatments in pods per plant , seed weight , seed yield and biological yield parametrs
respectively with 127, 20, 183, 109 persentage had better than control treatment.
