Influence of organic sources of nutrient on mungbean performance in South-eastern Rajasthan

A field experiment was conducted during the Kharif seasons of 2022 and 2023 at the organic farming block of the Agricultural Research Station, Ummedganj, Agriculture University, Kota (Rajasthan), to study the effects of organic sources of nutrient on mungbean growth and yield in the mungbean-wheat cropping system of southeastern Rajasthan. The experiment included eight treatments: T1 , Absolute control; T2 , 100% N by farm yard manure (FYM) + cow urine @ 10% spray at 15, 30, and 45 days after sowing (DAS); T3, 100% N by FYM + panchagavya @ 5% spray at 15, 30, and 45 DAS; T4 , 75% N by FYM + 25% N by vermicompost + vermiwash @ 10% spray at 15, 30, and 45 DAS; T5 , 50% N by FYM + 50% N by vermicompost + vermiwash @ 10% spray at 15, 30, and 45 DAS; T6 , 75% N by FYM + jeevamrut @ 500 liters/ha at sowing + vermiwash @ 5% spray @ 15, 30, and 45 DAS; T7 , 100% N by FYM + NPK consortia of biofertilizers + Zinc solubilising bacteria (ZSB) each @ 62.5 ml/kg seed inoculation + amrita sanjeevani @ 500 liters/ha at sowing, 15 and 30 DAS and 75% N by FYM + NPK consortia of biofertilizers @ 62.5 ml/kg seed inoculation + sasyagavya @ 10% spray at 15, 30, and 45 DAS (T8 ). The treatments were arranged in a randomized block design with 3 replications. The 2-years pooled results showed that the treatment T5 produced significantly higher values for plant height (54.62 cm), number of branches/plant (9.65), total number of effective nodules/plant (31.65), fresh and dry weight of root nodules/plant (119.94 mg and 23.98 mg, respectively), number of pods/plant (26.28), number of seeds/pod (9.39), pod length (8.17 cm), test weight (34.99 g), seed yield (1242 kg/ha), and straw yield (2,204 kg/ha) compared to the absolute control. These results were statistically on par with the T3 and T7 treatments, and the seed yield was found at par with T3 in the pooled analysis. Hence, the application of 50% N by FYM and 50% N by vermicompost, along with vermiwash spray, is highly effective mungbean yield in the South Eastern Rajasthan for enhancing.
