Intervention effect Under high EC, high transpiration increased blossom-end rot incidence to 20 percent relative to low transpiration.
Intervention effect Low transpiration with high EC reduced tomato size and yield by 15 percent relative to 2 dS/m.
Observation Under low transpiration, incidence of blossom-end rot was only 2 percent.
Intervention effect Dry matter and sugar content of tomato fruit were higher under high EC than under 2 dS/m.
Observation Total dry matter yield of tomato was the same across treatments except the high EC, high transpiration treatment.
Observation In the high EC, high transpiration treatment, blossom-end rot reduced marketable tomato dry matter by 25 percent.

Other claims from this paper (9)

Intervention effect A 3.5-day irrigation interval gave the highest mean sorghum yield, 7.57 Mg ha1, significantly above longer intervals.
Intervention effect Yield differed significantly among preplant only, 0.4 BI and 0.7 BI quantities.
Intervention effect Yield did not differ among 0.7, 1.0 and 1.3 BI treatments.
Intervention effect The 0.7 BI treatment had almost double the irrigation water use efficiency of 1.3 BI.
Observation Seasonal WUE was 1.69 kg m3 at 0.4 BI.
Intervention effect Preplant-only WUE was 1.52 and equaled the 0.7 BI treatment.

Influence of Japanese Brome on Western Wheatgrass Yield

Marshall R. Haferkamp; R. K. Heitschmidt; Michael G. Karl Journal of Range Management 1997. doi:10.2307/4002704

Other claims from this paper (6)

Intervention effect Removal of Japanese brome reduced total standing crop by 500 kg ha-1 in the western wheatgrass community.
Intervention effect Removal of Japanese brome increased standing crop of western wheatgrass by 220 kg ha-2.
Intervention effect Removal of Japanese brome increased tiller density of western wheatgrass by 153 tillers m-2.
Mechanism The increase in western wheatgrass standing crop appeared to result from increased tiller density rather than increased weight per tiller.
Intervention effect Western wheatgrass water relations were essentially unaffected by removal of Japanese brome in 1992.
Recommendation Removal of Japanese brome may increase production of associated perennial grasses.
