Field experiments were conducted on deep black soil of Mamurabad farm, Oilseed Research Station, Jalgaon (Maharashtra). Sesame cv. JLT-7 was sown during 2008,2009 and 2010 to find out suitable combination of soil and foliar application of urea and diammonium phosphate for seed yield maximization and remunerative treatments. Result revealed that, soil application of RDF + foliar spray of 2 per cent urea twice at flowering and pod formation stages significantly improved the yield attributes viz., number of capsules plant-1 and number of seeds capsule-1. These attributes contributed in producing significantly higher seed and oil yields and also proved more remunerative over soil application of RDF alone.

This study was conducted during the year 2006-07 and 2007-08 to determine how energy balances of crop production are affected by cotton-chickpea cropping sequence and different sources of organic and inorganic fertilizer under the semi-arid conditions of western Maharashtra. The energy input and output, energy balance per unit input ratio and the energy output/ input ratio were varied significantly individually to cotton and chickpea during both the years. However on pooled mean basis to cotton-chickpea cropping sequence, the energy input, output and energy balance were significantly higher by application of (RDF) Recommended Dose of Fertilizer according to Soil Test Crop Response (STCR) equation to cotton and 100% RDF to chickpea. Significantly higher energy balance per unit input and energy output per input ratio (6.46 MJ/ ha and 7.46) were recorded by 100% RDF + 10 FYM/ha to cotton and it was 5.72 MJ/ha and 6.72 by 100% RDF to chickpea. Application of RDF according to STCR equation ( 64960 and 3.07) to cotton and 100% RDF ( 46744 and 2.23) application to chickpea registered higher net monetary returns and benefit cost ratio respectively.
