Other claims from this paper (10)

Intervention effect Diphenamid applied two weeks after transplanting on previously cultivated soil gave superior weed control without apparent tomato injury.
Intervention effect Diphenamid applied after small weeds appeared gave poor post-emergence weed control.
Intervention effect Diphenamid applied after small weeds appeared gave poor tomato yield.
Association Weed competition suppressed tomato plant growth.
Association Weed competition accelerated tomato ripening relative to untreated cultivated plants.
Intervention effect Preplanting trifluralin gave good weed control.
Intervention effect Post-transplanting trifluralin gave poor weed control.
Intervention effect A higher trifluralin rate decreased tomato yield.
Intervention effect A diphenamid plus paraquat mixture controlled small weeds effectively.
Recommendation The authors judged the diphenamid plus paraquat mixture to have limited commercial potential because spray contact can injure tomato plants.

Masami HIMEDA; Seiichi IZUMI Japanese Journal of Crop Science 1965. doi:10.1626/jcs.33.399

Other claims from this paper (9)

Intervention effect More irregular disposition of rice plants caused a greater decrease in grain weight per unit area.
Mechanism Decrease of grain weight was caused by a decrease in the number of panicles per unit area.
Association In Fujiminori, the number of panicles decreased as irregularity in plant disposition increased.
Intervention effect In Fujiminori, grain weight per panicle remained unchanged as irregularity in plant disposition increased.
Association In Manryo, grain weight per panicle increased.
Association In Manryo, the number of panicles decreased.
Intervention effect In plots of cv 30∼100 %, no decrease of grain weight was observed relative to the plot of cv 0 %.
Intervention effect In Fujiminori, the decrease in grain weight with irregular disposition was more marked at low seeding density than at high seeding density.
Intervention effect In Manryo, the difference in the effect of irregular disposition on grain weight between spacing densities was not clear.

Poltavskaya, I. A. Defense Technical Information Center (DTIC) 1965

Other claims from this paper (12)

Intervention effect Nitrate nutrition increased wheat tryptophan and tyrosine content.
Intervention effect Ammonia nutrition yielded higher wheat cystine content.
Observation The amino acid difference occurred in vegetative and reserve proteins.
Mechanism Nitrate nutrition increased grain tryptophan and tyrosine through a rise in middlings yield.
Observation Middlings contain more of these proteins than gluten proteins.
Intervention effect Nitrogen top dressing at earing sharply increased gluten yield.
Intervention effect Nitrogen top dressing decreased percentage amino acid content.
Observation Absolute amino acid percentage in gluten did not fall because gluten yield was high.
Intervention effect Inadequate phosphorus increased wheat gluten yield.
Intervention effect Phosphorus deficiency reduced tryptophan content in gluten protein.
Intervention effect Phosphorus deficiency reduced total tryptophan content in wheat grain.
Recommendation The authors concluded normal phosphorus nutrition is important for wheat tryptophan synthesis.
