International Journal of Oil Palm (IJOP) is an online and print mode, a peer-reviewed research journal published by Indonesian Oil Palm Society (Masyarakat PerkelapaSawitan Indonesia, MAKSI), it provides a global publication platform for researcher, scholars, academicians, professionals and students engaged in research in oil palm industries. The main aim of IJOP is to become the world’s leading journal in oil palm that is preferred and trusted by the community through publishing authentic, peer-reviewed and scientifically developed research articles of international caliber. The journal is published three times in a year, 6-10 papers per publication, and the language of the journal is English. JOURNAL SCOPE IJOP publishes research papers in the felds of soil and crop fertilizer application, seedling preparation, cover crop management, leaf pruning, weed control, control of pest and diseases, insect pollinators management, water management, intercropping, cattle oil palm integration, environmental studies, harvesting technology, IT remote sensing GPS application, mechanization, sustainability standards, policy studies, social and economic studies, smallholders empowerment, palm oil mill improvement, biomass utilization, carbon footprint, water footprint, market studies, refinery, food and nutrition technology (oleofood, food safety, pharmaceutical, and nutraceutical) and also management of soil preparation, inorganic and organic safety, oleochemicals, downstream industry development, supply chain, and market studies. The published articles can be in the form of research articles, review paper or short communications which have not been published previously in other journals (except in the form of an abstract or academic thesis/dissertation or presented in seminar/conference).

Abstract

 In 2020 Indonesian smallholder farmers produced around 35 % of the total palm oil production, the most traded vegetable oil. Smallholders play an essential role in developing country economies – most strikingly due to their success at reducing poverty and improving social benefits. The cultivation of palm oil has proven benefits for the smallholders themselves and the local community. However, oil palm smallholders are at risk of being cut out of global supply chains by European union (EU) regulations. The EU’s discrimination against palm oil smallholders is wide-ranging, including the EU Renewable Energy Directive II and the forthcoming Due Diligence Regulation imposing restrictions designed to undermine Indonesian palm oil in the global marketplace. This paper elaborates on how palm oil smallholders contribute to desirable economic and social goals and how the approach of the EU is deliberately undermining those goals.

Abstract

Leaf spot is the primary disease on oil palm nurseries. The symptom of the disease is leaf spots are round to oval in shape and vary in color from yellow to brown to black. The initial size may be as small as a pin point. Some leaf spots initially appear as lesions. During disease development, leaf spots will have a contrasting colored edge or halo - e.g., brown spot with a yellow halo, tan center with brown edge or gray center with black edge and a yellow halo. As the leaf spots expand in size, the shape and coloration may change. As the disease progresses, leaf spots often coalesce (merge together) to form large areas of blighted tissue. If the disease continues to develop, leaflets or the entire leaf may die prematurely. The disease also causes stunted and even plant death. Disease control methods that rely primarily on biological agents and do not include fertilizers are less effective in the field. Therefore, the development of organic fertilizer formulations and the use of biocontrol agents are expected to assist oil palm nurseries in suppressing leaf spot disease. The purpose of this study is to investigate the effect of organic fertilizer and biocontrol agents on leaf spot disease. The results showed that the treatment of Organic Fertilizer and biocontrol agents was able to reduce 47.19% leaf spot disease after five weeks of application.

Abstract

 A long-term evaluation on fourteen D x P progenies of introgressed MPOB-Nigeria dura x AVROS pisifera were laid down in a randomized complete block design in two replicates with 371 palms in 2002. The aim was to evaluate the performance of fresh fruit bunch yield, bunch quality and vegetative traits among progenies. Analysis of variance revealed highly significant difference for all traits, indicating the existence of substantial variability within these population. In all cases, the phenotypic coefficient of variance was higher than the genotypic coefficients. Broad-sense heritability values estimated ranged from 8.85% to 100% for all the traits studied. The fresh fruit bunch also was found to be positively and highly correlated with bunch number, average bunch weight, oil yield ratio and kernel yield ratio. PK 3248 and PK 3166 were preferred as potential parental lines in breeding programmes and to be included in introgression with advanced breeding populations such as Deli dura.
