Phosphorus, an important constituent of biochemical products in plant itself; plays a key role in balance nutrition of the soybean and affect its productivity. Balanced fertilization is the key to achieve higher productivity and nutrient use efficiency and balanced nutrition with NPK proved beneficial in all the oilseed crops both under rainfed and irrigated conditions. Further, nutrients like S, Ca, Cu and B are also needed for higher yields (Ghosh et al., 2002). SSNM strategies that include site and specific knowledge of crop nutrient requirement and indigenous nutrient supplies is useful for improving nutrient use efficiency and crop productivity as well as for maintaining soil health in semi arid eco regions. Right fertilizer management must support stake holder’s to contribute goals of performance. The farmers are best managers International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 11 (2019) Journal homepage: http://www.ijcmas.com The field experiment was conducted to study the effect of omission of N, P and K fertilization and balanced NPK under it specific nutrient management in akola district in Vertisols. N omission with ample PK, omission of P with ample NK, omission of K with ample NP, and Ample NPK. The experiments comprised of four treatments as per the omission plot technique in randomized block design replicated on fifteen farmers’ fields and each farmer’s field considered as one replication. The treatment wise yield of seed and straw was recorded significantly highest with balanced application of NPK. The seed yield of soybean was most influenced by omission of phosphorus indicating that phosphorus is most crucial element in soybean production. Balanced application of NPK recorded higher protein content, oil content and test weight of soybean.
