Abstract:
Two soybean genotypes; indeterminate growth (1448) and determinate
growth (Egyptian)
were studied at the Demonstrated
Farm, College of
Agricultural Studies, Sudan University of Science and Technology, Shambat
during the season 2011, to examine the effect of different water levels (7 days,
14 days and 21 days). The experiment was arranged in the randomized complete
block design, divided in split plots, with four replications. Irrigation intervals
treatments occupied the main plots and genotypes in the sub - plots. Growth
parameters were; 50% flowering, plant height after 60 and 90 days from sowing
date, leaf area and number of leaves and yield parameters were: number of pods /
plant, number of seed / pod, number of seed / plant, weight of seeds / plant, 100
seed weight, harvest index and yield (kg/ha).
