Comparative agronomic evaluation of different cotton varieties under desert climate

Different cotton varieties were evaluated on the basis of there agronomic performance atBahawalpur, a desert region of Pakistan. Significant difference among varieties for plant height, numberof leaves, number of opened bolls, boll weight and seed cotton yield was found. Boll weight wasmaximum for NIAB-111(3.31g), while CIM-496 had higher plant height, number of leaves, number ofopened bolls and seed cotton yield as compared to other varieties. Similarly cotton varieties CIM-496,NIAB-111, BH-160 and CIM-534 were statistically better yielder giving 124.50g, 114.8g, 99.62g and98.63g seed cotton yield per plant respectively as compared to CIM-507 (77.00g/plant) and CIM-506(67.72g/plant) varieties. Therefore the better yielding varieties are recommended to be grown desertregion.
