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.

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.
Intervention effect The 3.5-day interval yielded higher WUE than the 14-day interval.
Intervention effect Applicator location had no significant response in yield, IWUE or WUE.
Recommendation The authors advise deficit seasonal LEPA irrigation near 0.7 BI when preplant soil water is adequate.

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.

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.

Other claims from this paper (11)

Observation Manganese and boron toxicities are more frequent in crops than other nutrient toxicities.
Observation Manganese toxicity occurs on acid soils.
Observation Boron toxicity occurs in irrigated regions whose waters are exceptionally high in boron.

Observation Crops near mines and smelters are prone to nutrient toxicity.
Observation Crop toxicity symptoms include leaf burning, chlorosis and yellowing.
Observation Copper and boron toxicity levels range from 20 to 50 μg g‐1.
Observation Manganese, molybdenum and zinc toxicity levels reach several hundred μg g‐1.
Intervention effect Liming can reduce toxicity of nutrients other than molybdenum.
Recommendation Recommended fertilizer rates and controlled waste use should reduce metal loading and crop nutrient toxicity.
Recommendation The authors recommend crop species and genotypes less susceptible to toxicity where toxicity is suspected.
