Other claims from this paper (15)
- Observation The hybrid varieties had significantly higher grain yields than Suwan5, ranked Big717 above Big949.
- Intervention effect Mn, Mi and Ma significantly reduced Suwan5 grain yields compared with CT and Pl.
- Intervention effect Big717 showed no significant differences among cultivation treatments.
- Observation Big949 responded significantly to cultivation treatment only in the second crop, particularly Ma.
- Observation Plastic mulch produced the highest average yields.
- Observation Manure produced the lowest average yields.
- Intervention effect Total aboveground biomass did not differ significantly among cultivation practices.
- Observation Total aboveground biomass differed between Suwan5 and the hybrids.
- Observation Harvest index was consistently lowest with manure for Suwan5 and Big949.
- Observation The tasseling-silking interval ranked Big949 above Suwan5 above Big717.
- Intervention effect Cultivation practices did not affect the tasseling-silking interval of Big717.
- Observation Manure gave the longest tasseling-silking interval in the other two varieties.
- Observation Suwan5 grew more vigorously at the early vegetative stage than the other varieties.
- Observation Manure produced the tallest plants within varieties.
- Recommendation The authors identify variety selection as a management tool for controlling drought effects.
