response of promising line n8119 of wheat to application of phosphate bio-fertilizer

in order to determine the effects of applied phosphate bio fertilizer on yield and morphological traits of wheat a research was conducted in sari agricultural sciences and natural resources university during 2008 2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio fertilizer (0 and 100 g ha 1) and the second factor was three levels of phosphate fertilizer (0 60 and 90 kg ha 1). results showed that bio fertilizer increased significantly grain yield spike/m2 seed /spike spike length 1000 seeds weight and harvest index however had no significant effect on plant height. there was no significant difference between 60 and 90 kg ha 1 phosphate fertilizer treatments obtained with 100 g ha 1 bio fertilizer (528.40 and 532.95 kg ha 1 respectively) in term of total grain yield. therefore application of 60 kg ha 1 phosphate fertilizer with bio fertilizer instead of conventionally using phosphate fertilizer in mazandaran (90 kg ha 1) not only save nearly 30 kg ha 1 phosphate fertilizer but also prevent soil and water pollutions.
