Abstract:
The district wise area, production and productivity of potato, maize and toria crops of 15 years (2004-05 to 2018-19) has considered for study. Potato crop data have been collected from Directorate of Horticulture Chhattisgarh Raipur were as maize and toria crops data have been collected from the Directorate of Land Record Government of Chhattisgarh Indirawati Bhavan, Raipur (C.G.). Potato and toria crop that are grown during rabi season and maize crop grown during kharif seasons of 16 districts of Chhattisgarh. The study used weekly weather data (SMW (Standard Meteorological Week)) collected from the Department of Agrometeorology I.G.K.V. Raipur for the years 2004-05 to 2018-19 for five weather variables: Maximum Temperature (TMAX), Minimum Temperature (TMIN), and Relative Humidity morning (RH1), Relative Humidity evening (RH2), Sunshine hours (SSH), and Rainfall (RF). Keeping in view the objectives set out for the study, following methods have been used. The data are analyzed by using software like SPSS (Statistical Package for Social Science), Weather Cock and MS-EXCEL. Results showed that RH negatively affect the planting to emergence & tuber bulking stage of potato crop while sunshine hours & RH were positively affect the plant senescence stage in most of the districts. In maize crop, the impact of SSH was negatively correlated during vegetative, tasseling/silking and physiological maturity stage while RH was positively correlated with vegetative stage. Positive effect of TMIN was observed during grain filling stage in most of the maize growing districts. SSH was negatively affects the vegetative, reproductive and maturity stages of toria crop, while TMIN and RH were positively correlated with reproductive and maturity stage. RF was also found positively correlated with reproductive and maturity stage in 9 districts of Chhattisgarh.
