Abstract

ABSTRACT Liquid organic fertilizer is able to provide nutrients from leachate extract (liquid) as a result of changes in worm metabolism, growing media or residual worm feed as a result of the composting process. This study aims to determine the interaction between feed type with worm colony weight as well as the influence of worm weight and type of feed on the quality of L. rubellus compost liquid organic fertilizer. The research was carried out at the experimental field of the Department of Agriculture and in the analytical laboratory of the University of Palangka Raya using completely randomized design (CRD) with 3x3 factorial pattern. The first factor was colony weights of L. rubellus (C1 : 50 g, C2 : 75 g and C3 : 100 g) and the second was types of feed (P0 : control, P1 : green vegetable waste and P2: sedge-grass leaves). The results showed that 100 g worm colony weights with feed from alang-alang leaves produced the highest Nitrogen nutrient (18.33 mg g-1), on phosphorus nutrients the interaction was not significant but had a significant effect from the treatment of feed where the green vegetable waste produced  the lowest phosphorus nutrients (85.67 mg g-1), but the treatment without feed (control) and sedge-grass leaves (Imperata cylindica) and the treatment of worm colony weight were not affect on the quality of L. rubellus compost liquid organic fertilizer. Keywords : Colony Weight, Feed Type, Liquid Organic Fertilizer, Lumbricus rubellus

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
