Abstract

Ultisol have low fertility, the sub soil of ultisol have fertility and organic matter content are very low. Compost of oil palm empty fruit bunches (OPEFB) and humic acid are useful improving fertility and organic matter content so that it can support growth of the plant. The research aims to study the effect of application of compost OPEFB and humic acid on sub soil ultisol to growth of the oil palm seedling’s in the main nursery. The experiment was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, Pekanbaru. The experiment were carried out in the form of factorial with a completely randomized design. The first factor is compost of OPEFB that consists of 4 levels (0, 25, 50 and 75 g/polybag) and as the second factor is the humic acid that consists of 3 level (0, 25 and 50 g/polybag). The parameters observed were statistically analyzed using analysis of variance, followed by Duncan’s multiple range test at 5%.The parameters measured were plant height, in the number of leaves, the increase in diameter stump, root crown ratio, dry seedling weight. The results slowed that the application of compost of OPEFB 25-75 g/polybag followed by humic acid 25, 50 g/polybag significantly increased plant height, in the number of leaves, the increase in diameter stump, root crown ratio, dry seedling weight composed than without compost OPEFB and humic acid, but now significantly with the other combination action.

Abstract

Palm oil (Elaeis guineensis Jacq.) is a plantation crop which is quite important in Indonesia because it accounts for foreign exchange and create employment that is high enough. Palm oil empty fruit bunches (EFB) is estimated at 20% of fresh fruit bunches ( FFB ) and coco in (cocopeat) are very much in Riau as raw material for fertilizer / compost. Subsoil ultisol a bottom layer of soil with sufficient depth within therefore very potential as a medium of palm oil nursery but has a low fertility signified by the nature of physics, chemistry and biology poor. Organic matter such as EFB compost and cocopeat can improve physical, chemical and biological subsoil ultisol. The research aimed to study the effect of EFB compost , cocopeat and a mixture of both the subsoil ultisol medium on the growth of palm oil seedlings in pre nursery. The study was conducted at the experimental station of Agriculture Faculty of the University of Riau from June to August , 2015. Research conducted an experiment using a completely randomized design (CRD) consisting of 6 treatments (K0 : without treatment , K1 : 100 g cocopeat , K2 : 100 g compost EFB , K3 : 50 g compost EFB + 50 g cocopeat , K4 : 75 g of compost EFB + 25 g cocopeat and K5 : 25 g compost cocopeat EFB + 75 g per plant) each repeated 4 times. The results showed treament EFB compost 50 g and cocopeat 50 g produce in the growth palm oil seedlings better than the other treatments on medium subsoil ultisol in pre nursery.

Abstract

Oil palm plantations in Riau are very extensive and developed on marginal land. The utilization of oil palm plant for soybean cultivation is an alternative to increasing soybean production in Riau, because soybeans are classified as plants that tolerant to shade. The research aimed to study the interaction of biochar and Calopogonium mucunoides green fertilizer on growth and yield of soybeans and diversity of soil macrofauna in inter-rows of oil palm plant. The research was conducted in Pekanbaru, carried out in 7-year-old oil palm plant and soil science laboratory of the Faculty of Agriculture, University of Riau from April-August 2018. The research was done experimentally in a 3x3 factorial form using a completely randomized design (CRD). The first factor is biochar from coconut shell consists of 3 levels (0, 2,5 and 5 ton.ha-1). The second factor is Calopogonium mucunoides green fertilizer consists of 3 levels (0, 2,5 and 5 ton.ha-1). The parameters observed were plant height, pods per plant, percentage of pithy pods, seeds per plant, seed weight per plot, weight of 100 seeds, population density and relative density of soil macrofauna, and diversity index of soil macrofauna. The results showed 2,5 ton.ha-1 biochar followed by 2,5 ton.ha-1 Calopogonium mucunoides green fertilizer increased the number of pods per plant compared to controls. The total individuals and population of soil macrofauna increased at 5 ton.ha-1 biochar followed by 5 ton.ha-1 Calopogonium mucunoides green fertilizer with the family that was often found, namely Scarabaeidae. The diversity index of soil macrofauna is low.
