In Madhya Pradesh and Rajasthan states in India, the soil analyses of farmers' fields revealed widespread deficiencies of S (9–96%), B (17–100%) and Zn (22–97%) along with that of P (25–92%). Soil organic C was deficient in 7–84% fields indicating specifically N deficiencies and poor soil health in general. During on-farm evaluations in rainy seasons 2010 and 2011, the soil test based addition of deficient nutrient fertilizers as balanced nutrition (BN) increased crop yields by 6–40% (benefit to cost ratios of 0.81–4.28) through enhanced rainwater use efficiency. The integrated nutrient management (INM), however, decreased the use of chemical fertilizers in BN by up to 50% through on-farm produced vermicompost and recorded yields at par or more than BN with far better benefit to cost ratios (2.26–10.2). Soybean grain S and Zn contents improved with INM. Applied S, B, Zn and vermicompost showed residual benefits as increased crop yields for succeeding three seasons. Hence, results showed INM/BN was economically beneficial for producing more food, while leading to resilience building of SAT production systems.","2013","published",,"Archives of Agronomy and Soil Science",,,"Taylor & Francis",,"1-16",,,,,,,,,,,"TRUE",,"0365-0340",,,,,,"","http://dx.doi.org/10.1080/03650340.2012.761336","http://scholar.google.co.in/scholar?as_q=%22Balanced+and+integrated+nutrient+management+for+enhanced+and+economic+food+production%3A+case+study+from+rainfed+semi-arid+tropics+in+India%22&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_","pub",,"Sir Dorabji Tata Trust, Mumbai","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
