Subiksa et al, 2018. Comparison Effect of Several Phosphate Contain Fertilizers to Nutrient Loss Trough Leaching on Peat Soil . JLSO 7(1):1-13. Peat soil have specific nutrient adsorption characteristics which are affected by soil pH dependent charge. Therefore, nutrient management on such soil should be done using different approach compared to mineral soil. Research on the comparison effects of several types of phosphate containing fertilizers to nutrient loss through leaching on peat soil has been carried out in greenhouse using coulom experiments. The objectives of this study was to evaluate the rate of primary macro nutrient loss and look for fertilization technology which can reduced leaching rate. The study used a randomized block design of 14 treatments with 3 replications. The treatments were complete control treatment, partial control and 4 types of P contain fertilizer, namely SP-36, NPK compound, Chrismast Island Phosphate Rock (CIRP), and Pugam each of them with 3 levels dose. The peat soil used was ombrogenous peat with hemic maturity level taken from OKI Regency, South Sumatra. Watering is done every 2 days with 350 ml ion-free water/pot. The results showed that N and K nutrients leaching, mostly due to aplication rate of those nutrient, whereas type of fertilizer was not revealed significantly different. Meanwhile, P concentration in leachate water was significantly different among treatments. Leaching of P in the control treatment was very low because of P content of peat soil was low. The highest loss of P trough leaching rate is shown by the NPK treatment because NPK compound is belong to fast nutrient release fertilizer. CIRP and Pugam treatments showed low P loss trough leaching rates due to the slow release of P on CIRP and Pugam. The low leaching rates of CIRP and Pugam are also because of high content of Al and Fe as polyvalent cation that can promote new soil positive charges as site adsorption of P. It can be concluded that fertilization with a slow release type of phosphate fertilizer and contain sesquioxide as source of polyvalent cations such as CIRP and Pugam can reduced the rate of phosphate loss trough leaching.

Abstract

Pratama et al, 2018. Oil Palm Breeding Program Strategy for Suboptimal Area in PT Binasawit Makmur  . JLSO 7(1):26-36. Suboptimal areas have great potential to be used an alternative land for cultivation of oil palm.We needed superior oil palm material to be able to grow well on that land. PT. Binasawit Makmur (BSM) through the Breeding Unit has developed a strategy regarding the assembly of superior material oil palm drought resistant. Therefore, this research aimed to develop  a strategy regarding breeding program in suboptimal lands of PT Binasawit Makmur.  The strategies used were  introducing, evaluating, and selecting genetic material based on productivity components (total and weight of fresh fruit bunches/ha, extraction rate) and high increment.  In addition, the efforts have been made to obtain drought tolerant material are conducting a progeny trial (DXP Trial) on mature palm to obtain drought tolerant in the dried season. Based on the results of the progeny trial, both of parents were traced to a crossing program. Currently, the seeds of the crossing have been obtained to confirm the results of the research on the nursery scale. In the nursery trial, research will be conducted to measure the proline content, stomata and chlorophyll content. Selection in the mature palm DXP progeny trial was followed by application a molecular tool such as SSR and SNP. Through this approach, a superior genetic material in terms of productivity and also drought tolerance can be developed and therefore can be used for recombination and release of new varieties.
