Influence of rainwater management through different agro-techniques on yield, yield attributing characters and economics of cotton

摘要

Influence of rainwater management through different agro-techniques on yield, yield attributing characters and economics of cotton was studied during 2003-2004, 2005-2006 and 2006-2007 at Department of Agronomy, Marathwada Agricultural University, Parbhani. The results revealed that intercropping of cotton with soybean produced higher seed cotton equivalent yield followed by cotton+blackgram and cotton+greengram and were superior over sole cotton. Gross returns, net returns and benefit : cost ratio of 2.68 were higher under cotton+soybean intercropping system. Among all the in situ soil moisture conservation techniques, opening of furrows in every row recorded highest water use efficiency (3.15 kg/ha-mm), followed by cotton+soy bean/blackgram/greengram intercropping system. However, quality parameters were not influenced by different in situ soil moisture conservation technique.
