Abstract
Spatial pattern of crop concentration and diversification in Chhattisgarh have been studied in the paper. Crop concentration index and diversification index are measured using Bhatia’s (1956) method. All 27 districts have been included to explain the spatial pattern of crop concentration and diversification scenario of Chhattisgarh. The crops having more than 1.8 % area to the total crops are considered for crop concentration index. In this way, eight crops are included for the study and paddy holds first rank in all the districts of Chhattisgarh. Rest of the five crops and two crops hold second and third ranks respectively. In this way, eight crops are first, second and third ranking crops. Maximum paddy concentration has been found in eastern part of middle Chhattisgarh plain (Mahanadi Sheonath doab, trans Mahanadi track and Raipur upland) where paddy concentration index is more than 1.1. Gram concentration has been observed in few districts of Chhattisgarh and this concentration (above 1) is noticed in western Maikal range is characterized by black soil. The spatial pattern of teora concentration is like the paddy concentration. High teora concentration is found in the plain of central Chhattisgarh. High concentration of Soyabean and wheat have also been found in western Maikal region. Maize and urad concentrations are high in Surguja Raigarh highland of north and Bastar plateau of south in Chhattisgarh where paddy concentration is least. These north and southern regions of Chhattisgarh are characterized by rough terrain. Kodo concentration is high in those areas where paddy cultivation is difficult. The spatial pattern of kodo concentration is just like the opposite of paddy concentration. Maximum kodo concentration has been found in Dantewada district having the index of 11. Insecurity has been found in one-third districts of this state in respect of food grains.
