Other claims from this paper (10)
- Observation The Nigerian long-season sorghum produced 15 tons dry matter per acre in about 155 days.
- Observation Its grain yield was 2000 lb/acre.
- Observation The American short-season hybrid formed one-half to one-third as much dry weight as Farafara.
- Observation The American short-season hybrid yielded over 4000 lb grain per acre in 100 days.
- Observation The intermediate Nigerian sorghum and long-season hybrid yielded more than the tall variety.
- Observation Long-season sorghum growth rates peaked in July, fell in September and rose at head emergence.
- Mechanism Increased radiation and head emergence contributed to higher growth rates before heading.
- Observation Farafara accumulated a larger share of post-heading dry weight in stems than the other long-season materials.
- Association Stem weight gain was inversely related to grain yield.
- Recommendation The authors recommend heads with sufficient grains to accommodate late-season assimilate for high yield.
