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 3 main plots in Strip-I (organic, natural and integrated farming) and five liquid organic manures (LOM’s) in strip-II (vermiwash @ 5%, jeevamrutha @ 20%, panchagavya @ 5%, cow urine @ 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 among the treatment interactions, recommended package of practices (RPP) recorded higher grain and straw yield (3901 and 5914 kg per ha, respectively) than other treatments. Increased grain & haulm yield resulted with remarkably higher plant N, P and K uptake (264.42, 66.71 and 176.09 kg per ha) and micro nutrients uptake viz., Fe, Zn and Mn (109.92, 31.68 and 35.00 g per ha) in RPP than other treatment interactions. Among treatment combinations, organic farming with panchagavya (A2B2) were recorded seed & halum yields (3845 and 6559 kg per ha, respectively) and micro nutrients viz., Fe, Zn and Mn (86.01, 24.89 and 29.65 g per ha, respectively) which were statically on par with RPP. Net returns and B: C ratio were higher with RPP and followed by CF, NF, INF and OF. A higher B: C ratio was reported by natural farming with panchagavya (A1B2) (3.96) next to RPP.
