Abstract

A field experiment was conducted at agronomy research farm of Karunya Institute of Technology and Sciences, Coimbatore during rabi season 2022 in order to look into the influence by inorganic fertilizer and various organic inputs on the crop growth and yield compared to organic fertilizer in greengram under irrigation. The experiment comprised of ten treatments viz. T1 : Absolute control, T2 : Vermicompost 100% + 2% Cowdung slurry, T3 : Vermicompost 100% + 2% biomineralizer,T4 : Vermicompost 100% + 2% EM solution, T5 : Vermicompost 100% + 2% pleurotus sp, T6 : Vermicompost 50% + RDF 50% + 2% Cowdung slurry, T7 : Vermicompost 50% + RDF 50% + 2% biomineralizer, T8 : Vermicompost 50% + RDF 50% + EM solution, T9 : Vermicompost 50% + RDF 50% + pleurotus sp and T10 : RDF alone were arranged in Randomized Block Design and replicated three times. Data was collected in 20, 40 DAS and at harvest stage of greengram crop. Results in all the growth parameters, yield and its attributes and economics had a significant influence under the inorganic fertilizer (100% RDF). The plant height (65.8 cm), dry matter accumulation (3871 kg ha-1) and number of pods/plant (12.32), number of grains/pod (7.2), grain yield (981 kg ha -1), haulm yield (2538 kg ha -1) of greengram were recorded in T10. On the basis of economics, the maximum gross returns (Rs.68670 ha -1), net returns (Rs. 39441 ha -1) and B: C ratio (2.34) was recorded under treatment (100% RDF).

Keywords: RDF, vermicompost, yield, economics
