RÉSUMÉ
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).
RÉSUMÉ
The aim of this study was to examine the effect of integrated nutrient management on the growth and yield of irrigated black gram. Pulses are also known as food legumes and they are second only to cereals in terms of production and consumption in India. A field experiment was carried out at Research Farm of Karunya Institute of Technology and Sciences, Coimbatore, Tamil Nadu during rabi season, (2022-2023) to Effect of Integrated Nutrient Management on growth and yield of irrigated blackgram crop with seven treatments and three replications under Randomized block design (RBD). The results indicated that the treatment with 50% RDF + 25% farmyard manure (FYM) + 25% Vermicompost (T7) performed well among all the treatments and recorded higher plant height (36.73cm), total dry matter production (2325 kg ha-1), grain yield (930 kg ha-1), stover yield ( 1395 kg ha-1), number of pods (20.65). The net return (25892 Rs ha-1) and B:C ratio (1.88) was recorded higher in 100% RDF.
RÉSUMÉ
A field experiment was conducted during the rabi season of 2022 in the farm of Karunya Institute of Technology and Sciences, Coimbatore to study the effect on organic nutrient management on yield and economic returns of baby corn which was grown in silty clay loam soil. Among all the treatment 12.5 t FYM + groundnut cake equivalent to 60 kg fertilizer N provided much better outcomes in terms of yield attributing character and cob yield followed by vermi-compost equivalent to N in 12.5 t FYM + groundnut cake equivalent to 60 Kg fertilizer N. B:C ratio was found higher in 60-30-30 kg NPK through fertilizer alone.
