Abstract

ABSTRACT Peatlands is a very specific ecosystem with conditions that are always flooded, fragile, relatively infertile, able to absorb more water, and bad aeration. Riau has the largest peat land, which is 64% of the total peatlands area in Sumatra, but the development of shallot has not been intensively cultivated. So it must be dealt with seriously. The use of compost fertilizer and the frequency of NPK apply can improve the nature of these peatlands and increase crop production. The aim of study was to determine the interaction effect and the main application of compost and the frequency of NPK apply to increasing shallot production on peat soil. Research conducted at the Faculty of Agriculture Experimental Farm, Riau Islamic University during 6 month, i.e. form March - August 2018. Factorial Completely Randomized Research design, the first factor was 10, 20 and 30 tons/ha of corn compost, the second factor was NPK 16:16:16 fertilization frequency 1 and 2 fertilizing doses of 150, 300 and 450 kg/ha. Parameters observed were peat analysis, tuber number, tuber diameter, wet tuber weight per clump, dry tuber weight per clump and percentage of tuber shrinkage. The results showed that the interaction and main effects were significant for all observed parameters with the best treatment of compost is 30 tons/ha and 2 times the fertilizer dose of 150 kg/ha per application (300 kg/ha).

Abstract

ABSTRACT The purpose of this study was to determine the interaction and main effects of herbafarm and NPK Mutiara 16:16:16 fertilizer on the growth and production of mung bean plants. (H) consisting of 4 levels namely 0, 1.5, 3, 4.5 cc / L of water, and the second factor is NPK Mutiara 16:16:16 (N) consisting of 4 levels of treatment namely 0, 10.8, 21.6,32.4 grams/plot, so that there are 16 treatment combinations with 3 replications there are 48 experimental unit plots. Each experimental unit consisted of 12 plants and 2 of them were used as sample plants so that the entire plant was 576 plants. The best treatment was giving herbafarm 3 cc / l water and NPK fertilizer pearl 21.6 g / plot ((H2N2) with the results the best filling speed of dry matter is 0.33 g, the percentage of planted pods is 71.33%, the weight of dry seeds is 27.50 grams per harvest. The main effect of giving herbafarm 3 cc / l water gives the best results on plant height 65.67 cm, age flowering 31.92 days, effective filling time 19.74 days and weighing 100 seeds 5.99 grams, while applying NPK pearl fertilizer 21.6 g / plot gives the best results on plant height 61.67 cm and effective filling time 19.90 days, but the application of pearl NPK fertilizer 32.4 g / plot gave the best results at the age of flowering 32.26 days and weighing 100 seeds 5.96 grams.
