Effect of Nitrogen fertilizer, Azospirillum and Pseudomonas bacteria on qualitative characteristics in Rice (Local CV)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 12
Abstract
The experiment was conducted to determine the effects of nitrogen and Pseudomonas flouresenceand Azospirillumbrasilnesisolates on Qualitative characteristics in rice (Oryza Sativa L.CV.Tarom) in amol city in 2013. The experiment was conducted as factorial design in randomized complete block with three replicants. The main factor included three levels of nitrogen (50, 75, 100 kg ha- 1 from urea source) and the side factor was pure PGPR isolates (Control, Azospirilumbrasilnesalone, Pseudomonasflouresencealone, AZB+PSF).In this studyQualityindicatorssuch asconversion efficiency, shell percentage, amylose content, gel consistency, gelatinizationtemperatureand protein contentwere measured. The Results showed that there were a significant difference onprotein, amylose content, conversion efficiency (p>1%).Interaction betweenbacteriaandnitrogen inthegel consistency andgelatinizationtemperatureandprotein were significant (p>5%). According to this results, the maximum measurement of proteinwas observed by the treatment 100 kg ha-1of N plus AZB + PSF (13%) and the minimum measurement of protein was observed in 50 kg ha-1 of N + control treatment (9%). And also the results of the this experiment indicated that the dual inoculation with AZB+PSF along with recommended N is beneficial to Rice cv. Tarom.
