TakeyaH. 3200833The main focus of this study was to determine the constraints faced by resource-poor farmers concerning the practice of ISF and NM systems of crop production. Field work was conducted in eight villages from four districts in Bangladesh and data were collected from 92 resource-poor farmers through group discussions and personal interviews. Four-point rating scales were used and summed to quantify farmers` constraints. Frequency distributions and a Constraint Index (CI) were used to measure the constraints faced by the different categories of resource-poor farmers. Present findings indicate that landless and marginal categories of resource-poor farmers faced comparatively more constraints than resource-poor small farmers did. Present findings also revealed that the constraint on landless and marginal farmers were similar, while the situation, faced by small farmers was different. Based on the Constraint Index (CI), the top two constraints for landless and marginal farmers were a lack of knowledge about ISF and NM systems and the lack of financial resources to buy fertilizers in time. On the other hand, the unavailability and unstable market price of fertilizers during crop seasons and limited initiatives by the agricultural extension department to motivate farmers to practice ISF and NM were the major constraints on small farmers according to the CI concerning the practice of ISF and NM regarding crop production.]]>Alexandrators, N.,19951995BARC,19991999BBS,20042004Chowdhury, S.M.U.,19961996CMEG,20072007Dayal, P.,20032003Doos, R.D.,199423124130FAO,19981998FAO,20032003IAC.,20042004IFPRI,20042004Lucas, B. and T.L.
