Abstract
Finger millet landraces viz., TZA-01 and TZM-01 were grown in glasshouses under two moisture regimes (fully irrigated and after drought) to investigate the effects of environmental stress on the growth, SPAD measurement, radiation use efficiency and yield of finger millet (Eleucine coracana). The drought treatment was imposed at 28 DAS beyond which no irrigation was applied to the droughted treatment. Growth and development were monitored between 21 DAS and 105 DAS. Soil moisture had an effect on the growth of both the landraces. Drought reduced leaf area, dry matter accumulation, seed weight, radiation use efficiency and yield of finger millet. LAI increased significantly in all the treatment between 28 DAS and 84 DAS, thereafter there was a sharp decline in LAI for TZM-01 under both irrigation and drought. Maximum LAI values
