Study of farmer"s adaptation of upland rice to rainfed bunded conditions

To solve this problem, farmers decided to try the upland rice variety UPL-Ri5 in their lowland bunded plots. This study analyzes the results of this experiment in terms of crop yield and quality. At the conclusion of the traditional lowland growing season in April, farmers generally assessed the performance of the UPL-Ri5 as comparable with standard lowland varieties. Although the upland variety produced on the average fewer tillers, all farmers commented favorably on its panicle exertion and good head fill, and its maturity period of between three to five months was comparable with the lowland varieties. Overall grain yields were comparable as well. These favorable assessments were supported by continued use of UPL-Ri5 in lowland bunded conditions, especially in the driest parts of the parcel due to the variety"s lesser tolerance of waterlogging. A total of 15 charts and figures are provided.
