Abstract
In order to study nitrogen rates effects and seed inoculation with rhizobium legominosarum and plant growth promoting rhizobacteria (PGPR) on yield and total dry matter of Chickpea (Cicer arietinum L.), a factorial experiment based on randomized complete block design with three replications was conducted at the farm of Shahrivar village (30 km from Ardabil) in 2013. Factors were nitrogen rates at four levels (0, 25,50 and 75 kg urea/ha) as N0, N1, N2 and N3 respectively and five levels of inoculation seed with rhizobium legominuzarum and plant growth promoting rhizobacteria as (without inoculation seed as control, seed inoculation with Rhizobium legominuzarum, seed inoculation with rhizobium Legominuzarum+Azosprillum lipoferum strain OF, seed inoculation with Rhizobium legominuzarum+Psedomonas putida, seed inoculation Rhizobium legominuzarum+Azosprillum lipoferum strain OF+Psedomonas putida) as T0, T1, T2, T3 and T4 respectively. The results of growth indices showed that in all of treatment compounds, total dry matter increased slowly until 25 days after sowing. From 25 till 105 days after sowing increased rapidly. From 105 till 115 days after sowing (harvest time), it decreased due to increasing aging of leaves and decreasing of crop growth rate. Maximum of total dry matter (374 gr/m2) belonged to the higher nitrogen rates (75 kg urea/ha) and seed inoculation as T4.While, the minimum of it was in without seed inoculation and nitrogen application. Plant height, number of pod per plant, grain 100 weight, grain yield, number and weight of nodules per plant were significantly affected by nitrogen rates and seed inoculation. Means comparison showed that maximum of grain yield (1276.78 kg/ha) and number of pod per plant (32.48) was obtained in the higher nitrogen rates. Increasing of nitrogen rates up 50 kg/ha increased number and weight of nodules per plant but it decreased in application of 75 kg N/ha. Minimum of these traits was obtained in without seed inoculation and nitrogen application. Seed inoculation with rhizobium and PGPR increased number and weight of nodules per plant. Maximum of these traits was obtained in seed inoculation with Rhizobium legominuzarum and Azosprillum+ Psedomonas.
