Abstract

The production of sugarcane in 2018 decreased due to the change in the cultivation method from lowland to upland. This research aimed to study the responses of growth and yield of two sugarcane varieties to the application of filter cake compost and inorganic fertilizer in upland sugarcane cultivation. This experiment was arranged in a split-split plot design consisting of three-factors, which were sugarcane varieties, the levels of filter cake compost, and the rates of inorganic fertilizer, assigned to the main plot, sub-plot, and sub-sub plots, respectively. The two sugarcane varieties were PS 881 and PS 862. The three levels of filter cake compost were 0, 5, 10 tons ha-1, and the four rates of inorganic fertilizers (percent of recommended dosage) were 25%, 50%, 75%, and 100%. The results showed that the growth and yield of PS 862 was better than that of PS 881, shown in the plant height, stem diameter, number of stems, and the length of internodes. The use of filter cake compost at a dose of 5 tons ha-1 was more efficient, and it could provide an efficiency of 0.097 tons per kg of cane at a dose of 76.76% inorganic fertilizer. Yet, it cannot reduce the use of inorganic fertilizer in producing sugarcane yield.

Abstract

Oil palm empty fruit bunches are materials used as organic fertilizers that can be applied to oil palm plantations, thereby reducing the use of inorganic fertilizers. Indigofera zollingeriana is an appropriate alternative as an interplant because of its high branch and leaf development. Functions as a ground cover and a supplier of carbon stocks naturally plays a role in water and soil conservation. This study aims to determine the effect of oil palm empty fruit bunches and I. zollingeriana on land improvement to support oil palm growth and production. Variables observed included changes in soil water content, soil microorganism activity, and carbon stock. The results showed that the soil planted with I. zollingeriana and given the empty fruit bunches of oil palm had a higher soil moisture content. The highest soil carbon stock, oil palm carbon stock, and vegetation carbon stock were 81.6 t ha-1, 36.60 t ha-1, and 1.89 t ha-1, respectively. The population and activity of microorganisms varies. The highest total microorganisms were treated with I. zollingeriana and oil palm EFB 105 (10⁵CFU g-1), while the lowest was 60 (10⁵CFU g-1). Planting I. zollingeriana and providing oil palm empty fruit bunches increased groundwater reserves by 36.71%.
