Abstract: Rice is one of the important staple cereal crops of the world with an area of 147.3 million ha and production of 518.4 million tonnes. In Asia, 90% of world’s rice is grown and consumed rice contributes around 45% of India’s cereal production and is the main staple food for over 60% of the population in the country. In C.G., Rice is cultivated in an area of 3.5 million ha with a total production of 5.9 million tonnes and productivity of 1646 Kg per ha. The data related to the productivity, area and production were collected from Department of Agriculture and Bio-technology, Chhattisgarh. Meteorological data were collected from different Agromet observatories located in the different station of IGKV, Raipur. The results showed that the values of coefficient of determination (R2) was 0.98, 0.99,0.98 and 0.99 in the zones 1, 2, 3 and 4, respectively. However all the values were found significant at 5%probability level during the period 1998-2007. Deviations in simulated yields showed positive correlation (r) values 0.51, 0.41, 0.27 and 0.22 in zones 1,2, 3 and 4 respectively. Average yield was found 1353 Kg ha-1 for zone 1, 1223 Kg ha-1 for zone 2, 1133 Kg ha-1 for zone 3 and 1288 Kg ha-1 for zone 4, respectively. It was concluded that CERES-rice can be utilized to predict development (phonological stages), growth, yield and yield attributes.
