Abstract :

Application of bio-fertilizers in Sustainable Agriculture perform important role at increasing of crop pro-duction and improving soil fertility. In order to investigate combine application of biological and chemical phosphorus fertilizers and micronutrients on morpho-physiologic characteristics of barley, present research was conducted via split plot experiment according randomized complete blocks design with three replications in Ramhormoz during 2016-17. The main treatments consisted of phosphorus fertilizers and bio-fertilizers in four levels (Non use phosphorus fertilizer or control, bio-fertilizer “Barvar2”, bio-fertilizer “Barvar2” with 150 kg.ha-1 superphosphate fertilizer and 200 kg.ha-1 superphosphate fertilizer) and spray micro-nutrient (included micronutrients of zinc, iron and manganese) at three levels (no spray micro-nutrient or control, spray micro-nutrient at 0.002 and 0.004 concentration) belonged to sub plots. Results of analysis of variance indicated effect of combine application of biological and chemical phosphorus fertilizers and micronutrients on measured traits was significant. Mean comparison result of phosphorus fertilizers showed that bio-fertilizer “Barvar2” with 150 kg.ha-1 superphosphate fertilizer had maximum peduncle length (9.46 cm), awn length (11.95 cm), leaf area index (4.5), chlorophyll index (40.26) and days to rippening (185 day) also spray micro-nutrient at 0.004 concentration achieved maximum rate of mentioned traits. According mean comparison results of interactions of treatments the highest seed yield (400.1 g.m-2) and main spike weight (2.89 gr) belonged to bio-fertilizer “Barvar2” with 150 kg.ha-1 superphosphate fertilizer and spray micro-nutrient at 0.004 concentration. Generally to achieved optimum yield use bio-fertilizer “Barvar2” with 150 kg.ha-1 superphosphate fertilizer and foliar application micro-nutrient at 0.004 concentrations for Ramhormoz weather conditions can be advised.
