Identification of Efficient Cropping Zone for Major Vegetable Crops in Different Districts of Chhattisgarh

Abstract

A study was carried out in the Department of Vegetable Science, IGKV Raipur to identify the efficient cropping zones for major vegetable crops grown in different districts of Chhattisgarh. Production and productivity of the Major Vegetable crops (Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra) for 6 years (2004-05 to 2010-11) and 8 years (2011-12 to 2018-19) were collected from the Directorate of Horticulture and Farm Forestry (Department of Agriculture, Government of Chhattisgarh) and Directorate of Economics and Statistics, Government of Chhattisgarh. Two indices i.e. Relative Spread Index (RSI) and Relative Yield Index (RYI) were computed and the potential cropping districts for the study crops were identified. The outcome of study conducted from 2004-05 to 2010-11, revealed that out of 18 districts, three, one, four, three, four, two, four and two districts were found most efficient cropping zones (MECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. Out of 18 districts, four, six, four, five, five, three, seven and six districts were fall under efficient cropping zones (ECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. In Chhattisgarh, among 18 districts, six, five, four, three, three, four, two and five districts were considered as a less efficient cropping zones (LECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. Similarly, out of 18 districts of the state, five, six, six, seven, six, nine, five and five districts were categorized under not efficient cropping zones (NECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively.
 Results obtained during 2011-12 to 2018-19 revealed that out of 27 districts, four, three, three, one, six, four, six and two districts were considered as most efficient cropping zones (MECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. Similarly, seven, ten, eight, seven, five, five, five and six were under efficient cropping zones (ECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. While, five, seven, six, six, six, six, five and eight districts were considered as a less efficient cropping zones (LECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively. Among 27 districts of the state, eleven, seven, ten, thirteen, ten, eleven, eleven and eleven districts are considered under not efficient cropping zones (NECZ) for Tomato, Potato, Chilli, Brinjal, Onion, Cauliflower, Cabbage and Okra, respectively.
 The outcome of analysis of long term data of area and production of vegetable crops grown in different districts of Chhattisgarh indicated that the area and production of various vegetable crops have been shifted from old districts two new districts during the period of 2004-2010 and 2011-2018.
