Abstract
A field experiment was carried out to evaluate the growth, yield, and quality performance of five cotton
(Gossypium hirsutum L.) cultivars viz. CIM-446, NIAB-999, NIAB-111, and CIM-473 & RH-511 at the farmer's field
under Toba Tek Singh, Pakistan conditions. The experiment was laid out in randomized complete block design
(RCBD) and was replicated four times. The net plot size was 7.0 m x 4.5 m. The data on various crop growth,
yield and quality attributes was recorded using standard procedures. Significant differences in respect of plant
height at maturity (cm), monopodial branches plant-1, sympodial branches plant-1, number of bolls plant-1, mature
boll weight (g), total seed cotton yield (kg ha-1), fiber strength (g tax-1), fiber fineness (mic.), staple length (mm)
and ginning out turn (%) were observed among all the cultivars except plant population which showed non
significant results. Statistically the maximum seed cotton yield (2917 kg ha-1) was produced by cultivar NIAB-111
while the minimum seed cotton yield of 1315 kg ha-1 was produced by cultivar RH-511. It was revealed from the
results that variety NIAB-111 proved to be best among all the five varieties particularly in respect of almost all the
agro-qualitative characters under Toba Tek Singh conditions.
