Problems are often found in soybean plants is the high level of flower and pods abscission. Flower and pods abscission can be caused by various factors such as high concentration of ethylene and low auxin and GA. Cow urine contains a lot of auxin, while goat urine a lot of GA. The aims of the research was to study effect of urine application on flower and pods abscission of soybean varieties. The experiment arranged using Randomized Completelly Block Design, consist of 2 factors, first factor was soybean varieties: Panderman, Burangrang and Anjasmoro. Second factor was urine application: without urine, concentration of cow urine (30 and 60 ml.l-1), concentration of goat urine (30 and 60 ml.l-1). Data were analyzed with F test, and were continuid with DMRT test at 5 percent and correlation analysis when significant. Results showed that urine application affected on the number and percentage of flower abscission. The percentage of flower abscission on Panderman variety decreased with cow or goat urine application, while on Burangrang variety, just cow urine application decreased the percentage of flower abscission. On Anjasmoro variety, cow or goat urine application not decreased the percentage of flower abscission. The highest decreased of the percentage flower abscission on Panderman and Burangrang varieties were cow urine application with concentration of 30 ml.l-1 , each were 7.90% and 6.24%. The seed yield (ton.ha-1), on Panderman variety just increased with cow urine of concentration 30 ml.l-1 , while on Burangrang variety, cow urine application with concentration of 30 or 60 ml.l-1 increased seed yield (ton.ha-1). On Anjasmoro variety, goat urine application with concentration of 30 or 60 ml.l-1 increased seed yield (ton.ha-1).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
