Other claims from this paper (9)
- Intervention effect Up to 120 kg/ha of nitrogen fertilizer in the dry season improved milling quality of the chalky varieties IR8, IR5 and Sigadis.
- Intervention effect Up to 120 kg/ha of nitrogen fertilizer in the dry season did not change milling quality of the nonchalky variety C4-63.
- Intervention effect Up to 60 kg/ha of nitrogen increased head rice yield of Sigadis, the most chalky variety.
- Intervention effect Up to 60 kg/ha of nitrogen left head rice yield unchanged in the other three varieties.
- Observation In the dry season, the optimum harvest time of transplanted rice for maximum grain and head rice yield and highest germination was 28 to 34 days after heading.
- Observation In the wet season, the optimum harvest time of transplanted rice was 32 to 38 days after heading.
- Association Lodging increased grain yield losses in both seasons, and losses were greater when plants were harvested late.
- Recommendation Lodging-susceptible rice varieties should be harvested earlier than lodging-resistant varieties.
- Intervention effect Nitrogen fertilization in the dry season delayed the optimum harvest time of the improved varieties IR8, IR5 and C4-63 by 2 to 4 days.
