Other claims from this paper (13)

Observation Low-temperature seed-yield loss arose mainly from reduced pod number or setting and fertile-seed percentage.
Observation Fertilizers differed statistically in pod number or setting rate.
Intervention effect Cold injury was least with farmyard manure and greatest with CDU.
Intervention effect Farmyard manure produced the highest total seed weight across cool treatments and control.
Intervention effect The four other slowly available nitrogen fertilizers exceeded high and standard ammonium sulfate for seed weight.
Intervention effect Leaf and stem weights at maturity were highest with farmyard manure.
Observation Nonnodulating soybean responded strongly to nitrogen fertilization in growth and yield, with a response trend contrasting with the nodulating line.
Intervention effect Slowly available nitrogen treatments produced about 30% less dry matter than high ammonium sulfate in the nonnodulating line.
Observation High manure nitrogen did not significantly depress fixation during development in nodulated soybean.
Intervention effect Farmyard manure again gave stable, high seed weight over three cool-exposure stages and control.
Intervention effect The 80% CDU and 20% ammonium sulfate mixture, with or without humate or oat straw, had seed yield as high as manure and above ammonium sulfate treatments.
Intervention effect Adding humate or oat straw increased 100-seed weight.
Intervention effect Adding humate or oat straw did not increase total seed weight.

Other claims from this paper (10)

Intervention effect Soybean seed yield rose with phosphate rate in all three growing conditions.
Intervention effect Low temperature caused the greatest soybean seed yield reduction at 6 g phosphate application.
Intervention effect Fused phosphate and superphosphate gave no significant soybean seed yield difference at equal rates.
Intervention effect Superphosphate improved early soybean vegetative growth and flower number relative to fused phosphate.
Intervention effect Fused phosphate increased soybean 100-seed weight relative to superphosphate.
Intervention effect At 15°C, soybean leaf and stem phosphorus was lower without phosphate, unchanged at 6 g, and higher at 18 g than controls.
Intervention effect The highest phosphate rate gave the best soybean growth during chilling and recovery afterward.
Association Soybean seed weight and stem weight were strongly positively related, with pooled correlation 0.962.
Association Soybean pod number and branch node number were strongly positively related, with pooled correlation 0.966.
Recommendation High phosphate application was recommended to reduce poor-growth injury of soybeans on volcanic ash soils.
