Effect Of Phosphate Fertilizer Application And Cow Manure On The Growth And Yield Of Edamame (Glycine Max L. Merril)

English

Abstract

Limited P availability in the soil is caused by the low solubility and absorption of P components, particularly in soils with low organic matter content. The purpose of this study is to investigate how phosphate fertilizer and cow dung fertilizer affect the yields of edamame crops. Between July and October of 2024, this study was carried out in Kaliurang Village, Jember, which is 146 meters above sea level and has an average temperature of 24 to 32 degrees Celsius (8o09'29.2"S 113o44'21.0"E). A Factorial RAK with two factors and three replications was used to design this experiment. There were three levels of phosphate fertilizer treatments: 1.7 g/plant, 2 g/plant, and 2.3 g/plant. Three levels of cow dung fertilizer treatment are available: 2 kg/plot, 4 kg/plot, and 6 kg/plot. Variables of observation, namely 2 kg/plot, 4 kg/plot, and 6 kg/plot. Observation variables included plant height, number of fertile nodes, number of pods per sample, pod weight per sample, and dry biomass weight. The results showed that the treatment interaction of 2,3 g phosphate fertilizer/plant and 6 kg cow dung fertilizer/plot had a significantly different effect in the dry biomass weight variable per sample (18,13 g). This is suspected to increase the availability of P in the root media, as the absorption of P by organic fertilizers also increases. Treatment of 2,3 g/plant of phosphate fertilizer had a significantly different effect on pod weight per sample (50,70 g). This is suspected to increase the availability of P in the root media, as the absorption of P by organic fertilizers also increases.
