In India, rice occupies an area of 44.59 million ha. The productivity of rice in our country is lower than many other countries, namely, South Korea, Australia, Japan, USA and China, etc. In Haryana, the total area under rice was 1087 ('000/ha) with production of 242.4 ('000 tonnes) and productivity 2386 kg/ha per hectare during 1999-2000. The present study was undertaken in a traditional rice cultivation tract of Haryana, particularly in Karnal and Kaithal districts of Haryana, from where unsustainability problems like decreasing productivity (in terms of decreasing output per unit of input) and environmental degradation were reported. These districts were selected purposively on the basis of highest area and production of rice in the state. The selected farmers were interviewed using a well structured interview schedule. Data were collected through personal interview technique. The correlation analysis results revealed that land holding, socio-economic status, education, family education, economic motivation, change proneness and attitude towards sustainability were found to have significant positive relationship with knowledge level of sustainable rice cultivation technology. 收起
