Achievements
- For characterization of weather conditions,
daily weather data for 30 years (1957-1997) were
analysed and normal values were
computed.
- In respect of crop-weather relations and
modelling large database for 7 years with rice crop was generated
both on meteorological factors. Phenology, dry matter and its
partitioning, leaf area index, specific leaf area, soil moisture
were monitored at 10-day intervals with three
sowing dates and five fertilizer treatments. CERES Rice model was validated
and modified for simulation of rice crop. Phenology, biomass
and grain weight could be successfully simulated. Further verification
is in progress.
- Dry matter production and its
partitioning in paddy was found to be dependent on soil moisture,
availability of PAR, and nutrient status in the soil. Optimum
sowing date for transplanting paddy in the region was found to be
around 25th
June.
