Studies on Cool Injury in Bean Plants : IV. Effects of nitrogenous fertilizers on the growth and yield of soybeans as subjected to low temperature from early to mid-reproductive stage

Koji HASHIMOTO; Tadashi YAMAMOTO Japanese Journal of Crop Science 1973. doi:10.1626/jcs.42.475

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.
