ABSTRACT Shallot is one of the horticultural commodities. Good cultivation of shallots is possible by applying chicken manure and NPK. Sufficient nutrient availability affects shallot growth and production. The purpose of this study was to determine the interactions between chicken manure and NPK factors and to determine the dose combination of the two fertilizers that resulted in the best gro…
ABSTRACT Forest betel (Piper aduncum L.) is a plant of the Piperaceae family whose leaves and fruit have potential as a vegetable insecticide. P. aduncum contains the active compound piperamide which is entered as a contact poison and works as a neurotoxin by interfering with nerve impulses in nerve axons. This study aims to obtain an effective concentration of betel leaf extract (Piper aduncum…
ABSTRACT The increase in population is always accompanied by an increase in land demand, on the other hand there has been a reduction in productive land due to industrial and housing needs, agriculture, and the plantation sector. The utilization of peatland for oil palm plantations in Sumatra in 2010 reached an area of 1.4 million ha. Making drainage and applying ameliorants and fertilizers wi…
ABSTRACT Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's prime crops. The Riau Province Plantation Office (2013) noted that in 2013 the area of oil palm plantations on peatland had reached around 1.2 million hectares. Of the total peatland area of oil palm plantations in Riau Province, there are different peat depths. The depth of peat determines the level of peatland production, becau…
ABSTRACT Upland rice plants (Oryza sativa L.) is a very important commodity in Indonesia because it is the main source of carbohydrates for the community. One of the main problems of Upland Rice Plant cultivation is the attack of the weevil (Leptocorisa acuta). L. acuta pest control is carried out by farmers using synthetic insecticides. This can cause resistance, recurrence, emergence of seco…
ABSTRACT Corn is one of the main food crops, apart from wheat and rice. One of the pests that can reduce productivity is the corncob borer Helicoverpa armigera Hubner. An alternative control is using vegetable insecticides which are selective for insects and relatively safe for the environment, namely from the Bintaro plant (Cerbera manghas L.). This study aims to obtain an effective treatment…
ABSTRACT The increase in the area of plantation crops such as oil palm and rubber is inversely proportional to the availability of land for plantation areas, resulting in the expansion of land on acidic mineral soils. This soil has a variety of problems with its physical, biological, and chemical properties. These problems then affects plants and earthworms. While the presence of earthworms is…
ABSTRACT Shallot is one of the horticultural commodities that has very good prospects. The low productivity of shallots is due to soil degradation, poor land management, cultivation techniques and the use of fertilizers that are not appropriate. This study aims to determine the interaction of tofu liquid waste and NPK Grower, and to get the right dose for the growth and production of shallot p…
ABSTRACT This study was carried out experimentally using a complete randomized design. The treatment is a combination of rubber leaf litter compost with NPK fertilizer consisting of 7 treatments, namely P1: NPK fertilizer 5 g per plant, P2: (rubber leaf litter compost 100 + NPK 2,5 g) per plant, P3: (rubber leaf litter compost 200 + NPK 2,5 g) per plant, P4: (rubber leaf litter compost 300 + NP…
ABSTRACT The production of sweet corn is influenced by the level of soil fertility. One alternative that can be done to increase soil fertility is by improving cultivation techniques through a fertilization system with the application of solid compost and NPK fertilizer. This study aims to identify the effect of the interaction of solid compost and NPK fertilizer, a single factor of solid comp…
ABSTRACT Aloe vera is a horticultural plant that has many benefits, such as cosmetic and medicinal raw materials. The growth of aloe vera is influenced by good cultivation efforts such as the use of planting media and provision of sufficient nutrients. Enough nutrients will affect the growth of the plant. The aim of this study was the main effects of empty fruit bunch ash and silver black mulc…
ABSTRACT Peanut (Arachis hypogaea L.) is a leguminosa plant that is quite important in Indonesia. Riau’s peanuts production in 2018 was 867 tons and in 2021 peanut production dropped drastically to 557 tons.
