The experiment was carried out at Main Agricultural Research Station, UAS, Dharwad, during Kharif, 2022–23 and 2023–24 with an aim to find out the insights into sustainable management strategies for soybean cultivation, balancing productivity with ecological conservation. The experiment consists of three farming practices in horizontal strips viz., Organic farming (OF), Natural farming (NF) and Intensification of natural farming (INF) and five liquid organic manures (LOM’s) in vertical strips viz., Vermiwash (VW) @ 5%, Jeevamrutha (JA) @ 20%, panchagavya (PG) @ 5%, Cow Urine (CU) @ 10% and water spray). The field had been passed through the transitional period of three years which is essential to convert into chemical free farming. On pooled basis, the results were organic farming recorded higher seed yield, halum yield, gross return and higher macro (NPK) and micro nutrients (Fe, Mn, Zn & Cu) uptake than natural farming practices. However, harvest index, net return and B:C ratio’s were higher with NF than both OF and INF. Among the LOM’s, PG recorded higher yield, gross return, total N uptake and micro nutrients uptake than others. But, NF recorded higher HI (42.88), net returns (`108931) and B:C ratio (3.96) than both OF and INF. The Seed and halum yields as well as gross returns of OF were compared with recommended package of practices (RPP). However, the best treatment NF recorded lesser NR by 16% and B:C ratio (0.39) than RPP.
