Abstract

The oil palm gives the highest yields per hectare of all oil crops at present. The high and increasing yields of the oil palm have led to a rapidly expanding world industry, now based in the tropical areas of Asia, Africa and America. The switch to the D x P or T hybrid planting material can increase productivity per unit area. However controlled pollination of oil palms is difficult and prone to various sources of error. Illegitimacy is a silent factor that has a negative impact on controlled crossing in the oil palm. Illegitimacy can happen in any stage of the controlled crosses in the oil palm, from the initial stage of selecting and labeling parents, to the initial stage in field trial. The use of molecular markers improves the integrity of breeding programs in perennial crops such as oil palm. In plant breeding programmes, it is important to know the parentage of families and individuals for a variety of reasons. SSR analysis can be used for correct parentage assignment in progeny trials of oil palm. Paternity analysis of 83 half sibs progenies from 5 female parents and one male parent with 16 SSR markers detected all individual that clearly belong to the family they were assigned.

Abstract

The main problem of sandy soils is low water holding capacity, resulting an occurance of water deficit. To overcome the problem, application of empty fruit bunch (EFB) is important. EFB application increases growth and development of fruit set and productivity, which causes an increase of palm oil absorbing ability to nutrients. Therefore, increasing potential effectivity of fertilizer in sandy soil is needed. Applying of EFB 79 to 268 kg.plant-1 .year-1 combine with inorganic fertilizer 2.8 to 6.0 kg.plant-1 .year-1 increased productivity simultaneously in years. Results showed that fertilizer application was more effective when applied under the heap of EFB, particularly in sandy soils.

Abstract

Embryogenic callus produced from somatic cells has a significant role in clonal propagation and oil palm breeding (assembly of superior varieties) through tissue culture techniques. Induction and development of embryogenic callus were determined by media composition, vitamins, amino acids, and growth regulators (hormones). This study aimed to determine the role of natural and synthetic hormone which supplemented in MS medium to induce embryogenic callus of oil palm. The research was conducted in laboratory of plant tissue culture, Stiper Agriculture Institute, Yogyakarta from February to May 2019. The explants were inoculated in solid MS medium with three treatments, namely MS medium (Murashige and Skoog), MS + synthetic hormone (2,4-Diclorophenoxyacetate), and MS + natural hormone (young coconut water). The results showed synthetic hormone (2,4-Diclorophenoxyacetate) which supplemented in MS medium can induce embryogenic callus of oil palm explants. However, natural hormone (coconut water) has not been able to induce embryogenic callus. Keywords: Callus induction, oil palm, 2,4-D, coconut water

Abstract

The aimed of this study was to determine the growth of oil palm seedlings at pre nursery in the nutrition modification and various types of media on hydroponic systems. The research was conducted at the education and research garden of the Stiper Agricultural Institute Yogyakarta, Maguwoharjo Village, Depok District, Sleman Regency, Yogyakarta Special Region in March to June 2016. The study used a split plot design. Main plot is a modification of nutrition consisting of three levels, namely nutrition A (15 g gandasil, 15 g hyponex, 0.78 g ZA, 7.5 g dolomite), nutrition B (15 g gandasil, 15 g hyponex, 1.17 g ZA, 11.25 g dolomite), and nutrition C (15 g gandasil, 15 g hyponex, 1.56 g ZA, 15 g dolomite). While the sub plot is a planting medium consisting of three types, namely rockwool, husk charcoal, and cocopeat. Observation data were analyzed by variance. To find out the significan difference between treatments is done by Duncan Multiple Range Test (DMRT) at a 5% significan level. The results of the analysis showed that nutrient modification had an effect on the number of leaves and leaf area, nutrients B and C were better than nutrition A, however, nutrition A, nutrition B, and nutrition C had the same effect on the growth of pre-nursery of oil palm with hydroponic systems. Various types of planting media influence the growth of pre-nursery oil palm seedlings, best on rockwool media. Keyword : oil palm, hydroponic, nutrition modification, planting media.
