ANALYSIS OF GROWTH AND PRODUCTION OF SOYBEAN (Glycine max (L) Merril) BY APPLICATION OF NPK COMPOST AND PALM OIL EMPTY FLOW PLANTS

Abstract

The research was carried out in Sei Kepayang Kanan Village, Sei Kepayang Subdistrict, Asahan Regency, North Sumatra Province with a height of ± 7 m above sea level with a flat topography. The study was conducted in March 2018 to May 2018. This research was conducted using a factorial randomized block design with 2 treatment factors and 3 replications. The first factor is empty Palm Oil Compost fertilizer with 4 levels, namely: TK0 = 0 kg / plot (control), TK1 = 1 kg / plot, TK2 = 2 kg / plot and TK3 = 3 kg / plot. The second factor is NPK administration with 3 levels namely N0 = No pruning, N1 = 0.015 g / plot and N2 = 0.03 g / plot. From the results of observations of NPK applications showed no significant effect on plant height aged 2, 4 and 6 MST, but had a significant effect on the number of branches per sample plant, number of filled pods per sample plant and production per plot. The NPK (N2) treatment showed the best effect on producing plant height (41.97 cm), number of branches per sample plant (1.52 branches), number of filled pods per sample plant (159.97 g), and production per plot ( 7.31 kg). The treatment of Palm Oil Empty Fruit Bunch Compost did not show any significant effect on plant height at ages 2, 4 and 6 MST, and also had a significant effect on the number of branches per sample plant, number of filled pods per sample plant and production per plot.
