The utilization of Dystrudepts as oil palm planting area has several problems such as high sand content, very low klei, low water holding ability, C-organic, KTK and interchangeable base levels (Ca, Mg, K, Na). Efforts to overcome these obstacles are with fertilizers that have slow release properties such as KCaMgS compound fertilizers combined with soluble fertilizers such as KCl. This researc…
Efforts to control pests in plant cultivation are recommended to use vegetable pesticides because they are not harmful to people or the environment. Gadung tubers (Dioscorea hispida) have potential as a vegetable pesticide. This research aims to obtain a concentration of gadung tuber extract that is effective in controlling corn armyworm pests. Observation parameters consist of initial time of …
Corn has a strategic role in the national economy as food, feed and industrial raw materials. Corn productivity in Riau decreases every year, one of which is caused by attacks plant pests, Spodoptera frugiperda J. E. Smith. This pest attacks the growing point of the plant which is marked by larvae scratches. Lime leaf (Citrus aurantifolia Swingle) a plant that has potential as a botanical insec…
Sycanus spp. is a common predator in oil palm plantations. These predatory insects have a variety of prey, and the level of attack from Setothosea asigna can decrease production by up to 40%.

Maize (Zea mays L.) is an important crop after rice and wheat. Maize production in Riau decreased by 16.562 ton in 2021 and 10.696 ton in 2022 caused by Spodoptera frugiperda J.E. Smith. S. frugiperda must be controlled so as not to reach the economic threshold, but many still use synthetic pesticides that cause resistance, resurgance, and explosions of secondary pests. An alternative is use a …
The productivity of oil palm plantations in Riau Province in 2021 in terms of oil palm plantations produced by smallholder plantations is still low compared to large state and private plantations. The low productivity of oil palm between smallholder plantations compared to large state and private plantations is due to poor management practices, one of which is frond management. Management of oi…
