Abstract

Soil fertility is one of the key success factors for managing independent smallholder oil palm plantation sustainably.  To improve soil fertility, the smallholder oil palm farmers depend highly on the chemical fertilizer which emits greenhouse gases N2O and are fragile to chemical fertilizer shortage. This dependency to chemical fertilizer and increased price of chemical fertilizer may cause some independent smallholder plantations are neglected and fruitless due to late nor absence of fertilizers.  In the country with plentiful of oil palm plantations, biomass of oil palm empty fruit bunch should be considered as a sustainable source of organic fertilizers.  This research examined the effect of dosage of composted oil palm empty fruit bunch enriched with multi functions multi microbial biofertilizer implanted within the soil below canopy edges of oil palm plants towards the growth and yield of oil palm plants. The treatments consisted of 3.5, 7.0, and 10.5 ton biofertilizer/ha and standard chemical fertilizer treatment as control. Each treatment was applied on ten plants. The results of this study showed that the biofertilizer application at 10.5 ton/ha improved the quality of soil better than other treatment of biofertilizer and standard chemical fertilizer.  The production yield of fresh fruit brunches of 10.5 ton biofertilizer/ha treatment was 31.5 ton/hectare/year. If the oil palm production is compared to farmer’s practice that produces 24 ton/hectare/year, these research results may promote better organic wastes management of oil palm plantation to better nourish the plants and improve sustainability of oil palm land system.

Abstract

Early Growth of Phaleria macrocarpaunder Different Shade Intensity and Doses ofVermicompost. Phaleria macrocarpaisshade plant,nativeto Papua-Indonesia. This is one of themost valuable herbal plants in Indonesia and widely grown in home gardens as well as in industrialareas.Organic matter incorporated into the media can increase nutrient availability, medium moisture,plant growth regulator, and improve soil structure to support root growth. In addition, light intensity isanother factor determined the optimum growth especially on shade plants. The research was aimed tofind the most appropriate dose and shade intensity to support early growth stage of Phaleriamacrocarpa.CompletelyRandomized Design was applied in Split Plot arrangement with threereplications. The shade intensity consisted of 0, 25, 50, or 75% while the dose of vermicompostconsisted of 0, 300, 600, or 900 g polybag-1. Research showed thatno interaction was revealed betweenshade intensity and dose of vermicompost on plant height, plant fresh weight and degree of leaf greeness.Root length and root dry weight responded linierly under 25, 50, and 75% shadesThere was no responseon plant growth with the increase ofdose of vermicompost when plants were grown without shading.The highest growth as shown on leaf number, leaf area, stem diameter, and root growth was under 50%shading and application 900 g polybag-1 of vermicompost. This research thus supports the previousreport that P. macrocarpa is less tolerance to full sunlight during its early growth.

Abstract

Poverty is still an insistent problem which when confronted by humanity requires a systemic, comprehensive and synchronized approach to alleviate it.  The concentration of urban and rural poverty in developing countries underpins the importance of agriculture as a poverty reduction strategy since most of the poor people depend on agriculture.  Thus, improving agricultural productivity, competitiveness and sustainability may reduce poverty.   This study was intended to (1) find out if sustainable agriculture, i.e., horticultural organic farming practices, could contribute to poverty reduction, (2) identify restrictive factors affecting horticulture organic farming development, and (3) formulate alternative policy intervention for poverty alleviation based on development of organic farming.   The respondents were selected using purposive sampling method, comprising of 22 self-claimed horticultural organic farmers and 22 horticultural conventional farmers.  The data were gathered through a structured-questionnaire and in-depth interview.   Descriptive statistics, prospective analyses and analytical hierarchy process were used to analyze the data.  The results showed that organic farming practices have potential to increase income of the horticultural farmers.  Factors that constrained the development of horticultural organic farming were limited knowledge of organic practices, access to market, financial and risk management services or support.  Alternative policy interventions, such as developing a linkage between producers and consumers, strengthening research and development on organic farming, enhancing dissemination knowledge of organic farming practices, and providing access to financial and agriculture management, are proposed.

Abstract

The growth of melon plant requires soil rich in organic matter, well drainage, and soil pH  6.0 – 7.0. The adverse conditions are found on mostly red-yellow podsolic of Ultisol. The objective of this research was to evaluate the application of goat manure and dolomite on growth and yield of melon. The research was held from June until September 2015 in Kandang Limun, Bengkulu City.  Completely Randomized Design was arranged involving goat manure doses consisted of 0 kg polybag-1, 3 kg polybag-1, and 6 kg polybag-1. Another factor was the dose of dolomite consisted of 0 g polybag-1 (0 tons ha-1), 100 g polybag-1 (2 tons ha-1) and 200 g polybag-1 (4 tons ha-1). Treatments were replicated three times, each experimental unit consisted of 4 polybags of plants. The result of this research revealed no interaction between goat manure and dolomite in affecting the vegetative growth of plants. The interaction between goat manure and dolomite was found affecting  fruit weight, fruit diameter and the thickness of edible fruit part. The highest values for fruit weight, fruit diameter, and edible fruit thickness were achieved on 3 kg polybag-1 goat manure  and 200 g polybag-1 dolomite treatment, which were 725.25 g, 17.14 cm, and  2.99 cm respectively. Goat manure dose of 6 kg polybag-1 increased stem diameter (5.5 mm) and fruit sweetness (8.09 0Brix) compared to treatment without manure which was 5.43 mm and 7.31 0Brix.
