A field experiment was conducted on sandy loam soil at the Punjab Agricultural University, Ludhiana, India, in 1996 to evaluate the effect of drip system and conventional furrow system of irrigation on the growth, yield and water use efficiency of American cotton (Gossypium hirsutum) cv. LH-846. The study revealed that the average plant height was found to be maximum in drip system (158.9 cm) with a high level of irrigation (IW/CPE=1.0) using fertigation as compared to furrow system (146.9 cm) having a high level of irrigation. The average number of bolls/plant were also found maximum in drip system (27.0 bolls/plant) as compared to the furrow system (20.3 bolls/plant). Results on seed-cotton yield was the same that for bolls production. The water use efficiency of 0.54 q/ha-cm was found in drip system as compared to 0.37 q/ha-cm in furrow system. Nitrogen use efficiency was found maximum in the drip system as compared to the furrow irrigation system.
