 ABSTRACT

Forty maize genotypes were studied for influence of moisture stress on yield and yield characters using line source sprinkler irrigation technique during rabi-summer, 2016-17 and 2017-2018 using line source sprinkler irrigation technique. The genotypes, G32-DMIL 50, G16-DMIL 13, G39- DMIDS 28, G4-DMIL 78, G28-DMIT 01, G38-DMIDS 15, G15-DMIL 23, G21-DMIL 47, G24-DMIL 84 and G37-DMIDS recorded higher yield compared to other genotypes. The genotype G32- DMIL 50 found promising under various moisture regimes. The genotype G32- DMIL 50 (96.50) and G16- DMIL 13 (91.80) recorded significantly higher cob weight (g/cob) at M1 moisture regime whereas, significantly lower cob weight (g/cob) was recorded in genotype G6- DMIT 30 (17.82), G12- DMIL 58 (18.45), G5- DMIL 150 (19.42), G19- DMID 16 (20.75), G7- DMIL 112 (22.15) and G17- DMIL 52 (22.23) at M5 moisture regime. G21- DMIL 47 (315.89), G28- DMIT 01 (314.83) and G24- DMIL 84 (311.70) recorded significantly higher number of seeds per cob and G6- DMIT 30 (96.67) and G19- DMID 16 (116.05) recorded significantly lower number of seeds per cob. Genotypes G12- DMIL 58 (87.30), G38- DMIDS 15 (85.01), G39- DMIDS 28 (84.99), G26- DMIL 63 (84.80), G24- DMIL 84 (83.83) and G4- DMIL 78 (83.44) recorded significantly higher shelling percentage.

Key words: Maize, Drought tolerance, Yield, Yield parameters, Moisture stress.
