Effect of organic and inorganic nitrogenous fertilizers on growth and yield of field pea (Pisum sativum L.)

Abstract

during the rabi season of the year 2022-2023 to study the "Effect of organic and inorganic nitrogenous fertilizers on growth and yield of Field pea (Pisum sativum L.)". The experiment was laid out in Randomized Block Design (RBD) comprising seven treatments viz; T1: Control, T2: 100% RDN, T3: 50% RDN + 50% VC (RDN), T4: 25% RDN +75% VC (RDN), T5: 100% VC (RDN), T6: 50% VC (RDN) and T7: 25% VC (RDN) with three replications. Result revealed that maximum plant height, number of leaves per plant, number of branches, fresh and dry weight of plant, seed yield and its attributing characters like number of pods per plant, number of seeds per pod, pod length, test weight, stover yield as well as harvest index were associated with T3. Available pH, and NPK content of soil was also found to be maximum in T3, however highest soil organic carbon content was found in treatment application of T5. Moreover, T3 recorded maximum gross return (₹/ha 109600), net return (₹/ha 64675) and B: C ratio (1.43). Thus from the present investigation, it can be inferred that application of 50% RDN (urea) + 50% VC (RDN) proved to be more productive and profitable for the cultivation of pea during rabi season of Manipur.
