Simulating the phenology, growth and yield of aromatic rice cultivars using CERES-Rice model under different environments

摘要

Field experiment were conducted during kharif seasons of 2007 and 2008 on silty loam soils of Nawagam under middle Gujarat Agroclimatic zone. Four aromatic cultivars of rice were transplanted on three dates to validate the CERES-Rice v.3.5 model. Highly positive significant association was found between simulated and observed days to heading (r = 0.95**). The model overestimated biomass production under estimated test weight and LAI. The performance of the model in simulating grains per square meterwas poor. The grain yield was simulated in close agreement with the field observed grain yield.
