In field experiments in 1988-91 at the Southeast Branch experiment Station near Rohwer, Arkansas on a Herbert silt loam, cotton was irrigated with a high, moderate or low frequency centre pivot block or furrow irrigated and given 0, 30, 60, 90, 120 or 150 lb urea-N/acre applied half before sowing and half at first squares growth stage. Irrigation significantly increased lint yields compared with dryland conditions. Yields were maximum with centre pivot irrigation in 1988 and 1991 and with furrow irrigation in 1990.
