Biofertilizer and Inorganic Fertilizers Effect on Favorable Characters for Productivity of Chickpea in Bundelkhand of Madhya Pradesh

Abstract

Background: A field experiment was conducted at the Instructional Farm of Krishi Vigyan Kendra, Chhatarpur during two consecutive rabi seasons of 2017-18 and 2018-19 to evaluate the effect of biofertilizers with 75% recommended dose of fertilizers on growth, yield, nutrient uptake, nutrient use efficiency and B:C ratio of chickpea (Cicer arietinum L.). Methods: In the two consecutive rabi seasons of 2017-18 and 2018-19, the experiment was laid out in randomized block design with improved wilt resistant variety of chickpea (JAKI 9218). Experiment consisted of five treatments including T0 (control), T1 (recommended dose of N:P2O5:K2O as 20:60:20 kg ha-1), T2 (recommended dose of NPK + seed inoculation by Rhizobium @ 10 g kg-1 seed), T3 (recommended dose of NPK + seed inoculation by Rhizobium and PSB separately @ 10 g kg-1 seed) and T4 (75% of recommended NPK+ seed inoculation by Rhizobium @ 10 g kg-1 seed + soil application of PSB and KSB each @ 5 kg ha-1) Result: The result showed that among the biofertilizers seed treatment with Rhizobium leguminosorum @ 10 gkg-1 seed and soil application of PSB and KSB @ 5 as above along with application of 75% recommended dose of fertilizers have been significantly enhanced root nodule formation, fertilizer use efficiency, productivity and reduced wilt infestation under this treatment followed by recommended dose of NPK + seed inoculation by Rhizobium and PSB separately @ 10 g kg-1 seed as compared to control plot.
