Improving biological nitrogen fixation (BNF) capacity and productivity of kabuli chickpea (Cicer kabulinum L.) varieties by molybdenum and PSB applications

Abstract

The experiment entitled “Improving biological nitrogen fixation (BNF) capacity and productivity of kabuli chickpea (Cicer kabulinum L.) varieties by PSB and molybdenum applications” was executed during rabi 2015-16 at the ICARDA – FLRP, Amlaha, Sehore (M.P.), India. Experiment consisted of twelve treatment combinations, laid out in Factorial randomized block design with three replications. The treatment were included four inoculants viz., control, Ammonium Molybdate (Mo @ 1 g/kg seed), Rhizobium + PSB and Rhizobium + PSB + Mo (1 g/kg seed) and three kabuli varieties (RVSJKG 102, Phule G 0517, PKV 4) for estimate the individual or combined effect of various treatment on BNF and crop productivity at field level. The soil was medium clay loam (Vertisol), low in available nitrogen, medium in phosphorus and medium in available potash with pH 7.5. Various growth and yield attributing characters were studied. The experiment was conducted with following objectives: 1. To determine the effect of PSB biofertilizer and Mo on growth, yield and quality of kabuli chickpea varieties. 2. To study the effect of PSB and Mo on root nodulation behavior of kabuli chickpea varieties. 3. To work out economics of different treatments
