A field experiment was conducted at Agricultural Research Station (MPUAT), Banswara (Rajasthan), India to assess the validation of SSNM practice in maize–wheat cropping system under sub-humid condition of southern Rajasthan. The experiment comprised seven treatments of absolute control (No nutrient), RDF-state, RDF-national, SSNM, SSNM-N, SSNM-P and SSNM-K. Treatments were applied in randomized block design with three replication at fixed site for both crops during both the years. Growth and yield attributes significantly influenced by nutrient omission treatments and their values were higher at nutrients that applied through SSNM approach. The target yield based SSNM nutrient management approach significantly increased grain yield by 32.43% of maize, 14.69% of wheat and 12.46% of system productivity over RDF, respectively. Omission of N and P resulted in 50 and 17.4 % reduction the grain yield, respectively. The yield reduction was slightly lower with K omission compared to SSNM-N and SSNM-P. The SSNM based NPK application was resulted in consistently higher gross returns of Rs 1, 48,547 and net return of Rs 1, 04,387 and B:C ratio of 2.36 of the maize-wheat cropping system. Overall, the results revealed that omitting N and P leads to significant yield penalty and application of nutrient using SSNM approach should adopted for achieving higher yield and profitability of maize-wheat cropping system.
