ABSTRACT
A field experiment was conducted during rabi 2012-13 at research farm of Directorate of Sorghum Research, Rajendranagar, Hyderabad. The experiment was laid out in a Split plot design, replicated thrice, with 10 sorghum genotypes as main treatment (well watered and water stress conditions) and with 10 genotypes are sub treatments CRS 4, CRS 19, CRS 20, PEC 17, CSV 18, M 35-1, Phule chitra, Phule moulee, EP 57 and CRS 1). Plant height of the genotypes ranged from 161 - 232 cm which registered positive and significant correlation with grain yield (r = 0.50). The number of green leaves was maximum in PEC 17 (13) The lowest number of leaves was observed in CRS 1 (9). The number of leaves in all the genotypes decreased due to the moisture stress imposed during post flowering period and the difference were statistically significant. Shoot dry weight, root dry weight and panicle dry weight were maximum in PEC 17 (41 g). The lowest values were observed in CRS 1 (27 g). The moisture stress imposed during post flowering period did not have any significant effect on shoot and root dry weight.
Key words :
Dry matter accumulation, Grain yield, Moisture stress conditions, Plant height, Sorghum genotypes.
