Optimizing wheat growth and yield through organic nutrient sources in South-Eastern Rajasthan

Abstract

A field experiment was conducted during the Rabi season of 2022-23 and 2023-24 at organic farming block of Agricultural Research Station, Ummedganj, Agriculture University Kota (Rajasthan) to study the effects of organic nutrient sources on growth and yield of wheat in South-Eastern Rajasthan. The experiment comprised of 8 treatments, viz. Absolute control (T1); 100% N by FYM + cow urine at 10% spray at 25, 50, and 75 DAS (T2); 100% N by FYM + panchagavya at 5% spray at 15, 30, and 45 DAS (T3); 75% N by FYM + 25% N by vermicompost + vermiwash at 10% spray at 15, 30, and 45 DAS (T4); 50% N by FYM + 50% N by vermicompost + vermiwash at 10% spray at 15, 30, and 45 DAS (T5); 75% N by FYM + jeevamrut at 500 liters/ha at sowing + vermiwash at 5% spray at 15, 30, and 45 DAS (T6); 100% N by FYM + NPK consortia of biofertilizers + ZSB each at 62.5 ml/kg seed inoculation + amrita sanjeevani at 500 liters/ha at sowing, 15, and 30 DAS (T7); and 75% N by FYM + NPK consortia of biofertilizers at 12.5 ml/kg seed inoculation + sasyagavya at 10% spray at 15, 30, and 45 DAS (T8), in a randomized block design laid with allocation of treatments in three replications. A critical examination of two years results revealed that significantly higher plant height, number of tillers/ meter row length at 30 & 45 DAS, Number of effective tillers/meter row length, ear length, number of grains/ ear, test weight, seed yield and straw yield of wheatwere obtained under the application of 50 % N by FYM + 50 % N by VC + VW @ 10 % spray at 25, 50 and 75 DAS (T5) over other treatments.
