Abstract
In order to investigate the effect of integrated application of chemical, organic and biological fertilizers on some of the morphophysiological traits of rice Tarom Hashemi cultivar, the present experiment was conducted in a randomized complete blocks design with 8 treatments and three replications at a research field of Amol in 2013-14. Treatments of the experiment consisted of: T1: Control or no fertilizer application, T2: nitrogen fertilizer application, T3: manure fertilizer application, T4: Azospirillum bacteria application, T5: manure fertilizer + Azospirillum, T6: nitrogen fertilizer + manure fertilizer, T7: nitrogen fertilizer + Azospirillum bacteria and T8: nitrogen fertilizer + manure fertilizer+ Azospirillum bacteria. Results indicated that experimental treatments had a significant effect on all under studied traits. Treatment of T7, had the highest plant height and the most filled grain number per panicle. Treatments of T6 and T7 had the most panicle number per plant. The lowest sterile floret number per panicle was observed in treatments of T7 and T8. Among treatments, treatment of T5 allocated the most one-thousand grain weight (25.97 gram) and harvest index (65.30 percent). The highest panicle length was belonged to treatments of T4, T5 and T6. The highest biological yield (7812 kilogram per hectare) and nitrogen of straw (15.67 kilogram per hectare) was observed in T6 treatment. The highest amount of grain yield and nitrogen storage in grain with averages of 4298 and 58.34 kilogram per hectare was belonged to T8 treatment, respectively.
