Field experiments were carried out during the rainy seasons of 1990 and 1991 on red sandy loam soils at IIHR, Bangalore, India, to determine the effects of irrigation (irrigation equivalent to cumulative pan evaporation (CPE) values of 40, 80 or 120 mm), water stress (120 mm CPE applied at the vegetative or reproductive stages) and N (0, 60, 120 or 180 kg/ha) on the growth and yield of chilli (cv. Arka Lohit). Plants receiving 40 mm CPE exhibited the highest dry matter production (89.2 g/plant), fruit yield (13.04 t/ha), N uptake (89 kg/ha) and water use efficiency. Imposition of water stress during the reproductive stage resulted in a lower reduction of yield (17%) compared with stress imposed during the vegetative phase (33%).
