Title
evaluation of effect integrated nutrient management of biological and chemical fertilizers on rice growth parameters
Authors
Abstract
Abstract
Integrated nutrient management of rice with application soil microorganism and chemical fertilizer play a key role in the increase sustainable rice yield. Thus a study purpose application of Herbaspiriliom bacteria and mychorhiza fungi in combination with different levels of nitrogen and phosphorous fertilizers was on growth index of rice. This research was conducted a randomized complete block design with three replications in split factorial experiments in Rice Research Institute in the city of Rasht in 2012 and 2013. Three nitrogen levels (50, 75 and 100% of the recommended dose) were in main factor and three levels of phosphorous (50, 75 and 100% of the recommended dose) with pure isolates of Herbaspirillum seropedicae bacteria, Glomus mosseae fungi and without inoculation as sub plots. The results indicated that the interaction of nitrogen and biofertlizer highest root dry weight 25/52 gr nitrogen level interaction alone (without the use of micro-organisms) and lowest root dry weight 13/85 g were obtained interaction tertiary nitrogen levels and non-inoculated. The appears to Mychorhiza fungi affected extended range of root morphological characteristics.
