e0“Statistical studies on five bean varieties, California Red, Sutter Pink, Pinto, Red Kidney, and Small White, planted at 2-week intervals from late May to late July over a four-year period indicated that yields increased up to mid-June, remained high through mid-July, and then declined in late July for four of the five varieties”
e1“The negative correlations between maximum temperature and beans per pod were smaller than between maximum temperature and per cent set, and only in Sutter Pink were they significant”

Other claims from this paper (17)
- Intervention effect Bean yields increased with planting date up to mid-June for four of the five varieties.
- Intervention effect Bean yields remained high for plantings through mid-July for four of the five varieties.
- Intervention effect Bean yields declined for late July plantings for four of the five varieties.
- Observation Small White did not mature in the mid-July planting in some years and never matured in late-July plantings.
- Observation Significant differences in yield were obtained among the bean varieties.
- Association Per cent flower set and beans per pod were significantly positively correlated in all three bean varieties.
- Association Plant age was significantly negatively correlated with per cent set in all three bean varieties.
- Association Plant age was significantly negatively correlated with beans per pod in all three bean varieties.
- Association Per cent set of Small White was significantly negatively correlated with maximum temperatures the day before, the day of and the day after bloom.
- Association Per cent set of Sutter Pink was significantly negatively correlated with maximum temperatures the day before, the day of and the day after bloom.
- Observation In California Red the correlations between per cent set and maximum temperatures were too low to be significant.
- Association The negative correlation between maximum temperature and beans per pod was significant only in Sutter Pink.
- Association Beans per pod in California Red were not affected by temperature.
- Observation California Red gave the highest yields, highest per cent set and highest beans per pod among the three varieties.
- Observation Sutter Pink ranked second in yield, per cent set and beans per pod.
- Observation Small White ranked third in yield, per cent set and beans per pod.
- Association Advancing plant age was more effective in reducing per cent set than were increasing temperatures.
