Other claims from this paper (14)
- Intervention effect Soybeans had little or no irrigation response in the wet 1974 season.
- Intervention effect Soil moisture regime caused growth differences in the dry seasons of 1975 and 1976.
- Observation Growth differences appeared first in leaves and stems during late vegetation and early bloom.
- Intervention effect Irrigated soybeans accumulated more dry matter and leaf area than nonirrigated soybeans.
- Intervention effect Irrigated soybeans had higher seed yields than nonirrigated soybeans.
- Observation Crop growth rates of irrigated and nonirrigated soybeans peaked in late July or early August 1974, then declined.
- Observation Irrigated soybean crop growth rate showed a similar seasonal pattern in 1975.
- Association Maximum crop growth rate corresponded to late vegetative and early reproductive growth.
- Observation Nonirrigated soybean crop growth rate peaked in mid-August 1975 during rainfall deficit.
- Association The nonirrigated crop growth rate peak corresponded to mid-podfill.
- Intervention effect Irrigated soybeans generally had greater growth parameter values during reproductive stages in a given year.
- Mechanism The 1975 decline in nonirrigated soybean leaf area ratio was attributed to reduced leaf weight ratio during vegetative growth.
- Mechanism The 1975 decline in nonirrigated soybean leaf area ratio during reproduction was attributed to reduced leaf weight ratio and specific leaf area.
- Mechanism Higher leaf area ratio in irrigated reproductive soybeans was attributed to a longer period of assimilate conversion into leaf area.
