Abstract
Agriculture is the backbone of the Indian economy. According to the Second Advance Estimates of National Income, 2022-2023 published by the Ministry of Statistics and Program Implementation (MoSPI), the share of Gross Value Added (GVA) of agriculture and allied sectors is 18.30 percent. Two-thirds of the total population of India is dependent on agriculture for its livelihood. Agriculture provides food and employment to the masses, green fodder for domestic animals, green manure for crops, and raw materials for agro-based industries. Therefore, the most crucial factor for improved agricultural output is a methodological, scientific, and appropriate cropping pattern as well as crop combinations. In this paper, an attempt has been made to show the changing scenarios of crop combination, crop concentration, and crop diversification regions in Koch Bihar district based on six principal crops such as aman paddy, boro paddy, wheat, jute, mustard and potato. The entire study is based on two latest agricultural data (2010-2011 & 2012-2013) of Koch Bihar district. Here, J.C Weaver’s method (1954), Bhatia’s location quotient method (1965), and Gibbs & Martin’s Techniques (1962) have been used for the delineation of crop combination, concentration and diversification regions. Study revealed that among the six principal crops of the district, Rice (aman) and jute have the highest concentration and are cultivated in every blocks. This might occur as a result of the favorable climate and significant alluvial deposits found throughout the district.
