Soybean Yield Optimization by Utilizating the Solid Waste of Oil Palm Factory

Abstract

Soybean is planted in some types of land agroecology, but production centers are mostly on peat and tides. This research was conducted at the soybean center in Rantau Rasau District with agroecology peat and tideland. The trial was arranged in a Randomized Block Design (RBD) with ten treatments and four times repeatitions. It consisted of several doses of organic material decanter cake (DC) and the percentage of the recommended amount of mineral fertilizer (RDF). RDF was selected based on Indonesia Food Crop Agriculture Service. Decanter cake from palm oil mill waste was used as a source of organic material. Experimental parameters are plant height, leaf number, grain yield, 100 grain weight, and the number of pods, seeds per pod, and plant. The result indicated the combination of mineral fertilizer and organic material DC had significant differences in increasing plant height and number of leaves. Different types of RDF and DC combinations showed substantial effects on the soybean yield and yield components. The combination of RDF 25% and decanter cake at any dose positively impacted soybean height, leaf number, and grain yield component. The highest dry seed yield of 2.48 tons per hectare was achieved by a combination of 25% RDF and 20 ton ha-1 decanter cake. Soybean yield in this study was higher than Anjasmoro’s description of 2.03–2.25 tons ha-1

THE YIELD OF ANJASMORO CULTIVARS SOYBEAN [Glycine max (L.) Merrill] WITH COMPOST TREATMENT FROM TOBACCO OR SOURSOP LEAVES AND ITS WEED CONDITIONS

“…This can be equated with yield per hectare, if a hectare there are 100,000 plants, according to this study it ranges from 1,361-1,543 tons ha -1 . This condition is smaller than other studies using organic fertilizer from solid waste Figure 5 Weight of soybean seeds every plant and 100 seeds from cooking oil factories, which reached 2.03-2.25 tons ha -1 (Duaja et al, 2022). Weeds absorb nutrients, water and light, thereby reducing soybean yields (Irfani & Agus, 2021).…”

The effect of palm oil (Elaeis guineensis Jacq) solid waste on the stomatal density and chlorophyll content of the pepper (Piper nigrum L.)

“…Many researchers have applied palm oil waste to improve plant growth and yield. Decanter cake derived from waste produced by palm oil mills was employed as an organic material source to enhance soybean yield [31]. Palm oil solid waste also influenced the plant height, flowering speed, and fruit fresh weight of green eggplant (Solanum melongena L.) [30,32].…”

Study on Relationship Between Agronomic Characters and Farming Value in Soybean Varieties Assessment

“…It is due to soybean is able to bond nitrogen from the air (Whitehead and Isaac, 2012). The application of single as well as compound fertilizers from nitrogen, phosphor, and potassium will significantly increase the harvest yields (Wijanarko and Taufiq, 2011;Duaja et al, 2022).…”
