Abstract
The present study entitled “Study on effect of climate variability on fruit crops in Haryana” was conducted inall the districts of Haryana. The objectives of the study were to investigate the spatio-temporal changes in fruit production and to examine the effect of temperature and rainfall on fruit production in Haryana state. Regression equation was used to analyze the temporal variation in the area and productivity of fruit crops (Mango, guava, citrus, ber, grape, aonla and chiku) while Arc-GIS software was used to analyze the spatial variation. Correlation analysis was carried to evaluate the impact of weather characteristics such as rainfall, maximum temperature, and minimum temperature on the yield of fruit crops. In majority of the district of Haryana average annual maximum temperature during second and third decade saw a decreasing trend. While the average annual minimum temperature was saw an increasing trend during second decade in districts Kurukshetra, Mahendragarh, Mewat, Palwal, Panipat and Sirsa. The scenario was similar in third decade except for district Mewat where it decreased by 1 °C. In all the districts of Haryana there was decrease in annual average rainfall in second decade than first decade except in the districts Ambala, Hisar and Jind. During the third decade there was decrease in annual average rainfall than second decade in the districts viz., Ambala, Bhiwani, Charkhi dadri, Fatehabad, Gurgaon, Mewat, Palwal, Panchkula, Rewari and Rohtak whereas Jind, Karnal, Kurukshetra, Mahendragarh, Mewat, Panipat, Sirsa and Yamunanagar observed increase in rainfall. The decreasing temporal trend in productivity was observed for grapes in Hisar and Sirsa, ber in Fatehabad, Jind, Sirsa, and Mewat; guava in Mewat; and aonla in Panchkula, Hisar, Sirsa, and Mewat. Likewise, the temporal trend in area of grapes in Hisar and Sirsa showed a drastic decreasing trend, as did that of ber in Hisar, Gurgaon, Faridabad, Rohtak, and Kaithal, mango in Panchkula, Panipat and Sonipat, guava in Panchkula, chiku in Ambala and aonla in Gurgaon. Fruit crops which showed a decreasing temporal trend in productivity in a particular district were significantly and negatively correlated with one or all of the weather parameters in that district. Similarly, fruit crops which showed an increasing temporal trend in productivity in a particular district were significantly and positively correlated with one or all of the weather parameters in that district.
