Effect of integrated nutrients management through organic sources on growth parameters and yield of chickpea (Cicer arietinum L.)

The present investigation entitled “Effect of integrated nutrients management through organic sources on growth and yield chickpea (Cicer arietinum L.)” was carried out at the Research Farm at Faculty of Agriculture, Dr. C. V. Raman University, Vaishali, Bihar during Rabi season of the year 2020-21. The experiment was laid out in a randomized complete block design with three replications comprising nine treatments. Use of organic sources (FYM, Poultry manure and Vermicompost) significantly influenced growth parameters, yield attributes and yield of chickpea crop. The conjoint application of FYM + Vermicompost + Poultry manure + Rhizobium (T8) resulted increased significantly all the growth parameters viz, plant height, root length, numbers of primary branches, no. of secondary branches plant-1were noticed at 30, 60, 90 DAS and at maturity stage while all the growth parameters minimum recorded in T0 (Control). Integrated nutrients management through organic source and sowing method significantly influenced the entire yield attributes viz, number of pod plant-1, pod weight plant-1, grain weight plant-1 and 100 seed weight were recorded with T8 (FYM + Vermicompost + Poultry manure + Rhizobium) while T0 (Control) recorded lowest in all the parameters. The maximum grain yield (Kg) ha-1 was recorded maximum T8 (FYM + Vermicompost + Poultry manure + Rhizobium), presented 2289 kg ha-1 while T0 (Control) recorded lowest grain yield recorded 1548 kg ha-1. From present investigation, it can be concluded that above integrated nutrient management sources organic manure (FYM + Vermicompost + Poultry manure) and application of Rhizobium resulted in better growth, higher yield and besides enhanced soil health as evident by post-harvest soil fertility status. It can be suggested as a cost effective combination for getting higher yield with greater quality on a sustainable basis.
