The present investigation was carried out to study the Effect of BBF and soil amendments on soluble cations and anions, available NPK and soybean yield in salt affected soils of Purna valley in Vidarbha region of Maharashtra. The treatments comprised of only BBF, BBF + FYM @5 t ha-1, BBF + gypsum @ 2.5 t ha -1 and BBF + FYM @ 5 t ha-1 + gypsum @ 1.25 t ha -1 combinely. Treatments replicated in six farmers’ fields one farmer as one replication with randomized block design. In this region shallow saline groundwater table, poor drainage and sub soil Sodicity are the main problems. In this context, BBF and soil amendments were drawn more attention to ameliorate these degraded soils. Under the study pHs was influenced slightly under all treatments and higher rate of decrease was noticed in treatment T4 (8.24). By incorporating FYM @ 5 t ha-1 highest ECe was noticed in T2 (0.78 (dSm-1). It was significantly less (0.54 dSm-1) inT1where only BBF was practiced. Use of FYM and gypsum recorded considerable increase in soluble Ca, Mg and K but decrease in Na. In respect of bicarbonates the significant reduction was observed in treatment T3, BBF + gypsum@ 2.5tha-1. Concentration of chlorides and sulphates also reduced in T4 (1.06 (me L-1) due to combined application of FYM @ 5 t ha-1 and gypsum @ 1.25 t ha-1. InT3 also observed remarkable reduction over T1.However, the combined practice of BBF with organic and inorganic amendments reportedly profitable in amelioration, nutrient uptake and also a great advantage in straw and grain yield of soybean for salt affected soils of purna valley in vidarbha
