The Growth Response And Yield Of Peanuts (Arachis hypogaea L.) On Dose Of Kcl Fertilizer And Pile Up Frequency / Tanggap Pertumbuhan dan Produksi Kacang Tanah (Arachis hypogaea L.) Pada Dosis Pupuk Kalium dan Frekwensi Pembumbunan

Attempts to increase the yield of peanut can be done with fertilizer and pile up. The purpose of the study was to determine the response of KCl fertilizer and pile up frequency on the growth and yield of peanuts. The research was conducted at Pasar I Tanjung Sari street, Medan with the height of 25 metres above sea level, began from April until Juli 2013. The design of the research was a randomized block design with two factors. The first factor was dose of KCl fertilizer (0, 50, 100, and 150 kg/ha) and the second was pile up frequency (20; 20 and 40; and 20, 40, and 60 days after planted). The parameters observed were plant height, number of branches, flowering age, number of ginofor per sample, number of pods per sample, number of filled pods per sample, weight of pods per plot, weight of grain per plot, and weight of 100 grains. The results showed that the weight of pods per plot and weight of grain per plot were significantly affected by pile up frequency. However all parameters observed were unsignificantly affected by dose of KCl and treatment interaction.
