Other claims from this paper (16)
- Observation Seven C. maxima types had statistically comparable yields under irrigated and dryland production.
- Observation Dryland yields were 76% of irrigated yields in 2016.
- Observation Irrigated Tetsukabuto had the greatest yield, averaging 51.4 t·ha −1.
- Observation Irrigated Tetsukabuto had the greatest fruit number per hectare, averaging 12,080.
- Observation Irrigated Tetsukabuto had the greatest fruit number per plant, averaging 1.94.
- Observation Tetsukabuto yield was comparable with other varieties in dryland production.
- Association Planting density affected fruit weight, fruit number per hectare, and fruit number per plant.
- Association Planting density did not statistically affect yield in irrigated or dryland production.
- Association Irrigated fruit weight fell from 1.89 to 1.30 kg with increasing density.
- Association Fruit weight fell from 2.04 to 1.56 kg with increasing density in the 2016 dryland trial.
- Association Fruit weight fell from 1.42 to 0.93 kg with increasing density in the 2017 dryland trial.
- Association Irrigated fruit number per hectare rose from 6660 to 10,590 as density increased.
- Observation Plants produced no more than two fruit per plant on average across varieties with irrigation, even at the lowest density.
- Recommendation Farmers can adjust squash fruit size by changing planting density.
- Mechanism The authors attribute very low 2017 dryland yields to unusually high summer temperatures in western Oregon.
- Recommendation The authors warn that increasingly hot summers may make dryland squash production unfeasible in western Oregon.
