Effect of varieties, plant densities and fertility levels on American cotton (Gossypium hirsutum L.) under rainfed conditions.

摘要

Field experiments conducted for two consecutive kharif seasons of 2002-2003 and 2003-2004 at the Regional Research Station, College of Agriculture, Khandwa (M. P.) revealed that the new American cotton genotype KH-117 under closest plant density of 45x45 cm and highest fertility level of 100:50:25 NPK (kg/ha) recorded highest values of average gross income/ha. But, intermediate fertility level of 80:40:20 NPK (kg/ha) recorded highest average net income/ha indicating optimum economic dose for hirsutum cotton varieties under rainfed conditions in the tract.
