Estimation of the effect of weather parameters on castor yield of Banaskantha district in Gujarat


Author(s): AG Sabhaya, DV Patel and PB Marviya

Abstract: In the present study, “Estimation of the effect of weather parameters on castor yield in Gujarat” attempts have been made to develop models for forecasting castor yield at Banaskantha district on the basis of weather variables. Weekly data from 32nd meteorological standard week (MSW) to 9th standard week of next year. The weekly average of weather variables (rainfall, maximum and minimum temperature, morning and afternoon relative humidity and sunshine hours) over a span of 31 years period (1981-82 to 2011-12) has been used along with the annual castor production data for Banaskantha district of Gujarat state. For early forecast, 12, 9, 6 and 3 weeks intervals were considered. The stepwise regression procedure was adopted using 31 years data for selection of variables. These models for respective districts can be used for providing pre-harvest forecast, 9 weeks before expected harvest in case of Banaskantha districts. The study showed that models selected for pre-harvest forecasts explained more than 90% for Banaskantha district. The errors of simulated forecasts were less than 3 per cent in model.
