Design and performance of paired row drip irrigation system on yield attributes of cotton

摘要

To study the effect of paired row system of 100/140 cm drip irrigation along with four levels of drip irrigation and three levels of fertilizer on the yield of TCHB 213 cotton, three set of experiments were conducted during 1996-2001 at the research farm of Tamil Nadu Agricultural University, Coimbatore. The number of bolls per plant and the kapas yield were recorded and analysed. From the individual year analysis it is revealed that 75% of control (IW/CPE=0.6) water through paired row drip combinedwith 75% of recommended dose of NPK for TCHB 213 cotton stood to be the optimum combination of the two factors (Irrigation and fertilizer) which consistently increased the Kapas yield of TCHB 213.
