Abstract

Palm oil (Elaeis guineensis Jacq.) is a plantation commodity which plays important role in economics of Indonesia. Palm oil can grow at various ground type by paying attention to the soil characteristics including soil biology. Soil biology like existence of soil macrofauna depend on availibility of energy such as organic matter and decomposed it, so that can maintain the soil productivity. This research aims to determine the effect of organic matters and to determine the better of organic matters for soil macrofauna and palm oil growth. This research has been conducted at the experimental farm of Agricultural Faculty Riau University on May to August 2015. This research was carried out experimentally by using randomized block design (RBD) with 4 treatments (without organic matter, palm oil empty fruit bunch, sawdust and congongrass of 10 kg/plant) and 6 replications, so there are 24 experimental units.The data obtained were analyzed using ANOVA and followed by further test DNMRT at 5% level. The result showed that the application of 10 kg/plant sawdustgave the best for number of individu, number of type and population densityof soil macrofauna. The application of 10 kg/plant palm oil empty fruit bunch showed the best results for increasing of plant height, increasing number of fronds, increasing of fronds length and increasing of leaves.

Abstract

Recently, fertilizer is considered as necessary cultural practices that could increase soybean production. So, this experiment was intended to determine the role of phosphorous fertilized on seed development and seed quality of several soybean varieties. Three varieties of soybean were grown in a plot of 3.2 by 3 m with planting density 40 x 15 cm. Ten days after planting, the plant were fertilized by mixing 53 kg Urea, 53 kg KCl and TSP as treatment applied. To obtained seed water concentration and seed dry weight, 300 flowers were randomly chosen from each plot, and 10 pods developed from the flowers were harvested every 5 days beginning from 15 days after anthesis (DAA) to 50 DAA. In addition to seed development, we observed dry matter accumulation rate, effective filling period, and seed quality at harvest. The change in seed moisture content was relatively fast from 15 DAA to about 45 DAA, then slightly slow until harvest time. Seed dry weight was very small until 20 DAA and contribute only 5 to 7% of its maximum dry weight. The linear increase in seed dry weight occurred from 20 DAA until 45 DAA, then tent to slow down before reaching physiological maturity. Application of P fertilizer increased KPBK and shortened WPE on Wilis and Gema but did not impact both traits on Gema. Grain yield of Kaba and Wilis was higher when fertilized by 25 kg P2O5 per ha, and tent to decline if fertilized by 50 kg P2O5 per ha.   Key Words : seed water content, seed dry weight, P fertilizer, seed development
