ABSTRACT Oil palm is one of the most abundant plantation crops in Indonesia and is one of the most important plantation commodities in the country's economy. This study aims to see the influence of the interaction between humic acid and sludge compost, the single factor of humic acid and sludge compost, and to obtain the best combination of humic acid and sludge compost on the growth of oil pa…
ABSTRACT Oil palm is the largest oil-producing crop in Indonesia. Increasing sustainable oil palm production is done by rejuvenating old and damaged plants. In rejuvenation, the quality of seedlings is considered such as the availability of nutrients in the media. The purpose of this study is to determine the interaction of various types of biofertilizers with NPKMg fertilizers, the single…
ABSTRACT Red chili (Capsicum annuum L.) is one of the horticultural commodities that is widely cultivated commercially because it has high economic value. One effort to increase red chili production is to increase the availability of nutrients in the soil by combining biofertilizers with NPK fertilizers. Providing a combination of inorganic and organic fertilizers has a good impact on plants. …
ABSTRACT Oil palm (Elaeis guineensis Jacq.) is a leading commodity in Riau Province. A total of 129,274 hectares of old and damaged oil palm land need rejuvenation which requires quality seedlings. Ultisol planting media, which is commonly used, has low fertility constraints. This study aims to test the influence of humic acid and N, P, K fertilizers and determine the best dose for the growth …
ABSTRACT The low production of okra in Riau is due to low soil fertility, especially on marginal land. This study aims to determine the interaction effect of moringa leaves liquid organic fertilizer and various planting distances, single factor of moringa leaves and planting distance, and get the best concentration of moringa leaves liquid organic fertilizer and planting distances. The researc…
ABSTRACT Onion plants (Allium ascalonicum L.) are plants originating from Asia that have a high selling value. Efforts can be made to increase shallot productivity and increase soil fertility by applying biological fertilizers. The use of biological fertilizers is not sufficient in meeting the needs of nutrients needed by shallots optimally, so it needs to be combined with NPK fertilizers.…
ABSTRACT Oil palm (Elaeis guineensis Jacq.) is a plantation crop that is a leading commodity in Indonesia, especially in Riau Province. Riau Province has sandy soils (Dystrudepts) that are often used for oil palm plantations. This soil has a very fast percolation and high leaching risk, so it requires the selection of slow-release fertilizers namely Polyhalite and combined with KCl. The purpos…
ABSTRACT Sweet corn (Zea mays saccharata Sturt.) can be cultivated in acid soils with low nutrient availability. A combination of biofertilizer and NPK is required as biofertilizer alone is insufficient. To maintain microbial effectiveness, this study used Mucuna bracteata as a storage medium for biofertilizers.This research was conducted experimentally using a Completely Randomized Design (CR…
ABSTRACT The decline in maize production in Riau province is caused by the attack of plant disrupting organisms, namely armyworms (Spodoptera frugiperda J. E. Smith). S. frugiperda attacks meize plants in the vegetative phase up to the generative phase. The use of synthetic insecticides can cause negative effects. The solution to reduce the use of synthetic insecticides is to find alternatives…
ABSTRACT Rice plant (Oryza sativa L.) is a rice-producing plant and the main food commodity for the Indonesian population. intensification is one of the efforts to increase agricultural yields by fertilizing using both inorganic and organic fertilizers.
