Abstract: A field experiment was carried out during the winter season of 2019-20 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the effect of nutrient management practices on growth, yield and nutrients content and uptake by chickpea (Cicer arietinum L.) under organic farming. Total nine treatment combinations viz., T1 : FYM 5 t/ha + panchagavya spray 3% at branching and flowering, T2 : FYM 5 t/ha + cow urine spray 5% at branching and flowering, T3 : FYM 5 t/ha + vermiwash spray 10% at branching and flowering, T4 : FYM 2.5 t/ha + seed inoculation with rhizobium and PSB + panchagavya spray 3% at branching and flowering, T5 : FYM @ 2.5 t/ha + seed inoculation with rhizobium and PSB + cow urine spray @ 5% at branching and flowering, T6 : FYM @ 2.5 t/ha + seed inoculation with rhizobium and PSB + vermiwash spray @ 10% at branching and flowering, T7 : Castor cake @ 0.5 t/ha + panchagavya spray @ 3% at branching and flowering, T8 : Castor cake @ 0.5 t/ha + cow urine spray @ 5% at branching and flowering and T9 : Castor cake @ 0.5 t/ha + vermiwash spray @ 10% at branching and flowering were laid out in randomized block design replicated 3 times. Application of 5.0 t FYM/ha along with two foliar sprays of 3% panchagavya at branching and flowering recorded the maximum value of all growth parameters viz., plant height, number of branches per plant, dry matter accumulation per plant, number of root nodules per plant and dry weight of root nodules per plant and yield attributes viz., number of pods per plant, seed index as well as seed and stover yield of chickpea besides improving quality parameter (protein content). However, it was found at par with 0.5 t castor cake/ha along with two foliar spray of panchagavya at branching and flowering, 5.0 t FYM/ha along with either two foliar spray of 5% cow urine or 10% vermiwash at branching and flowering stages. It also uptake maximum total N and P2O5 by chickpea, net returns and benefit cost ratio.
