Abstract

In order to study of the effects of biofertilizers on growth indices and contribution of DRY MATTER remobilization in wheat grain yield, a factorial experiment was conducted based on randomized complete block design with three replications. Factors were: NITROGEN application time at three levels, (1/3 planting, 1/3 tillering and stem elongation, 1/3 before flowering), (1/4 planting, 1/2 tillering and stem elongation stages, 1/4 before flowering) and (1/4 planting, 1/4 emergence, 1/4 stem elongation, 1/4 flowering) as N1, N2 and N3 respectively. Seed inoculation treatments with PGPR containing control (without inoculation) seed inoculation with Azotobacter chrocoococum strain 5, Psedomunas strain 41 and 186. Maximum of DRY MATTER remobilization per plant was obtained in NITROGEN application time as N1 without seed inoculation and the least was obtained in NITROGEN application as N3 and seed inoculation with Azotobacter. Grain yield per plant, number of grains per spike, hundred seed weight, plant height, root weight and protein content (%) increased at NITROGEN application as N1 and seed inoculation with PGPR. DRY MATTER accumulation increased slowly at all treatment combinations until 40 days after sowing (DAF), then increased rapidly till 70 (DAF). Then it decreased till harvest time due to aging of leaves. So, it can be suggested that in order to increase grain yield and other growth indices, NITROGEN should be applied as N1 in combination with seed inoculation with Azotobacter.
