Abstract
A simulation study on growth and development of sorghum (Sorghum
bicolor (L.) Moench) was carried out during 1989-90 at CASAM Pune, India. The
CERES-Sorghum model used in this study was designed to simulate the effects
of cultivar, planting density, weather, soil water and nitrogen on crop growth,
development and yield. Input values required include daily climatic data on
solar radiation, maximum and minimum temperatures and precipitation; crop data
on cultivar name, planting date, plant population and genotype specific
coefficients; soil data on drained upper limit of soil water availability, lower limit
of plant extractable soil water, saturation water content, initial soil water
content, drainage rate content, stage I evaporation coefficient, soil albedo and
runoff curve number. Two sorghum genotypes, M-35-1 and SPV-504 were taken
up for study.
