Abstract

ABSTRACTThe purpose of this study was to determine the growth and yield of onion that were given growth regulator (PGR) and NPK fertilizer on spodosol. This study used Randomized Block Design (RBD) of factorial pattern with two factors: (1) growth regulator (0, 3, 6, and 9 mL.L-1 ), and (2) NPK fertilizer (0, 150, 300, and 450 kg ha-1). The results of this study showed tha giving of PGR increased the crop growth rate of plants aged 14-21 day after planting (1.057 g.m-2 day -1) and 21-28 day after planting (1.089 g.m-2 day-1) with the best concentration of 6 mL.L-1 water. The best NPK fertilizer dosage of 300 kg.ha-1 was able to increase plant height at 42 day after planting (46,89 cm), leaf area 21, 28 and 35 day after planting (541,22 cm2, 717,37 cm2, and 714 , 29 cm2), weight of fresh stover (75,50 g), weight of dry stover (66,19 g) and tuber weight per plot (4,520,25 g).Key words : onion, plant growth regulator (PGR), NPK, spodosol
