A field experiment was conducted to compare the performance of drip and sprinkler irrigation systems on the growth and yield-related parameters of American cotton (Gossypium hirsutum) cv. L-846 at the research farm of Punjab Agricultural University, Ludhiana, India. There were two levels of irrigation (i.e., low and high, with IW/CPE ratios of 0.75 and 1.00, respectively); and two methods of fertilizer application in drip (i.e., manual application and fertigation). The result shows that plant height was maximum in the sprinkler system (159.10 cm) compared with the drip system (158.90 cm) with low level of irrigation using fertigation. The number of bolls per plant was maximum in the drip system (22.96) with low level of irrigation, and in sprinkler system (22.20) having treatment of fertigation, respectively. There was no significant difference between all treatments in quality traits (i.e., fibre length, micronaire, fibre maturity coefficient, fibre bundle strength and oil content). The maximum yield (31.10 q/ha) was found in the drip system with low level of irrigation followed by sprinkler system (28.60 q/ha) with high level of irrigation. Water use efficiency (0.47 q/ha-cm) and nitrogen use efficiency (41.47 q/ha-kg) was higher in the drip system compared to the sprinkler system.
