Abstract
A field experiment was carried out during therabiseason of 2004-05 to find out the effect ofRhizobiumand phosphate solubilizing bacterial (PSB) inoculants on symbiotic traits, nodule leghemoglobin, and yield of five elite genotypes of chickpea. Among the chickpea genotypes, IG-593 performed better in respect of symbiotic parameters including nodule number, nodule fresh weight, nodule dry weight, shoot dry weight, yield attributes and yield. Leghemoglobin content (2.55 mg g−1of fresh nodule) was also higher under IG-593. Among microbial inoculants, theRhizobium+ PSB was found most effective in terms of nodule number (27.66 nodules plant−1), nodule fresh weight (144.90 mg plant−1), nodule dry weight (74.30 mg plant−1), shoot dry weight (11.76 g plant−1), and leghemoglobin content (2.29 mg g−1of fresh nodule) and also showed its positive effect in enhancing all the yield attributing parameters, grain and straw yields.
Highlights
Pulses are the second most important group of crops after cereals
International Journal of Agronomy of chickpea to inoculation with Rhizobium and phosphate solubilizing bacterial inoculants is meager under such situation, an experiment was designed to assess the productivity of chickpea genotypes in combinations with microbial inoculants in Malwa Region of Madhya Pradesh
The experiment was conducted with twenty treatment combinations comprising five genotypes, namely, IG-226, IG-370, IG-379, JG-412, and IG-593, in main plots and four microbial inoculants in sub-plots
Summary
Pulses are the second most important group of crops after cereals. Developing countries contribute about 74% to the global pulses production and the remaining comes from developed countries. India is the largest producer and consumer of pulses in the world contributing around 25–28% of the total global production. The poor productivity of chickpea in this region is mainly due to imbalance application of nutrients and use of traditional varieties. Under such situations, use of Rhizobium and phosphate solubilizing bacteria (PSB) had shown advantage in enhancing chickpea productivity [3, 4]. International Journal of Agronomy of chickpea to inoculation with Rhizobium and phosphate solubilizing bacterial inoculants is meager under such situation, an experiment was designed to assess the productivity of chickpea genotypes in combinations with microbial inoculants in Malwa Region of Madhya Pradesh
