Other claims from this paper (6)
- Association Pod yield of peanut cultivars showed a significant cultivar by irrigation treatment interaction when crop water deficits occurred throughout pod growth.
- Intervention effect Severe stress during the pod filling phase caused the greatest reduction in peanut yield.
- Observation Significant cultivar variation in peanut pod yield was apparent.
- Observation Transpiration efficiency estimated from leaf carbon isotope discrimination varied only slightly among peanut cultivars.
- Mechanism Transpiration efficiency contributed little to pod yield variation among peanut cultivars (author interpretation).
- Mechanism Variation in pod yield among the four peanut cultivars was largely explained by differences in harvest index characteristics (author interpretation).
