dc.description.abstract | Cotton–wheat is the second most important cropping system after rice–wheat in Indiaand Pakistan, and is practiced on about 4.02 mha. By 2010, more than 6 million Indian farmers had adopted transgenic Bt cotton on 9.4 mha—almost 90% of thecountry’s total cotton area. There is a paucity of information on the effects of intercroppingand integrated nitrogen (N)–management practices in transgenic Bt cottonon productivity, nutrient availability, and soil biological properties in the succeedingwheat crop in a cotton–wheat system. A study was made to evaluate and quantifythe residual effect of two-tiered intercropping of cotton and groundnut with substitutionof 25–50% recommended dose of nitrogen (RDN) of cotton by farmyard manure(FYM) on productivity and soil fertility in a cotton–wheat system at New Delhi during2006–2008. Wheat following groundnut-intercropped cotton receiving 50% RDNsubstitution through FYM had significantly 5% greater grain yield than that after sole cotton. Residual soil fertility in terms of organic carbon (C), potassium permanganate(KMnO4)-N, and dehydrogenase activity (14%) showed an improvement under cotton+groundnut–wheat system with substitution of 50% RDN of cotton by FYM. Apparent Nbalance as well as actual change in KMnO4-N at wheat harvest was negative in most ofthe treatments, with greater loss (–58.1) noticed under pure stand of the cotton–wheatsystem with 100% RDN of cotton through urea. The study suggested that inclusionof legume and organic manure in transgenic Bt-cotton–wheat system is a sustainablepractice for combating escalating prices of N fertilizers with environmental issues and instability of transgenic hybrids in south Asian countries. | en_US |
