Owing to poor rainfall and drastic climatic changes farmers often face challenges to sustain cultivation of crops with respect to crop cycle. With growing economic competition and rising population, governmental agencies design long term plans which rarely address the farmer's needs. To meet the global demands agriculturist needs to investigate every opportunity that could improve agricultural production and growth. Whether to expand agricultural lands or to improve the production farmers needs to assess the suitability between land and crops. The investigation of land suitability and crop suitability has attracted many researchers to utilize latest technology such as remote sensing, geographical information systems etc. This paper aims to survey on recent researches on crop and land suitability using data mining techniques.
