The aim of this research was to obtain the best dosage composition of rice husk zeolite (ZSP), banana hump LOF, N and P fertilizer to increase the growth and …
The aim of this research is to determine the combination of vermicomposting with NPK fertilizer and to obtain the right dose to improve the growth of oil palm (Elaeis guineensis Jacq.) seedlings in the main seedling phase in Inceptisol soil. This research was carried out at the experimental garden of the Faculty of Agriculture, Riau University, Bina Widya campus km 12.5, Pekanbaru. This researc…
The decrease in corn crop yields in Riau Province was possibly caused by several factors, one of which was the infestation of plant pests such as the corn cob borer (Helicoverpa armigera Hubner). The primary choice for farmers to control H. armigera was using synthetic insecticides, but this could lead to various negative impacts. A solution to reduce the use of synthetic insecticides was the …
Rice (Oryza sativa L.) is an important food crop commodity in Indonesia because rice is the staple food for about 95% of the Indonesian population. This means that an increase in population is followed by an increase in the need for rice. One of the efforts that can be done through upland rice cultivation on Ultisol land but Ultisol soil has limiting factors both physically and chemically. Tech…
The development of aren palm plants is highly dependent on the seeds used, which come exclusively from seeds. One problem in the provision of aren palm seeds is seed dormancy. This issue can be addressed by soaking the seeds in HCl solution. This study aims to determine the effect of soaking aren palm seeds in various concentrations of HCl solution and identify the optimal concentration of HCl …
Cultivating shallots in an environmentally friendly manner can be done with the application of biofertilizers so it is hoped that this can reduce the use of inorganic fertilizers. The effectiveness of bacteria in biofertilizer can be optimized by adding Mucuna bracteata. This research aims to find the best combination of sludge oil palm and biofertilizer added to M. bracteata to increase the gr…
This study was conducted using a completely randomized design (CRD) factorial consisting of two factors. The first factor is NPK fertilizer consists of three levels P1 : 33 g, P2 : 40 g, P3 : 47 g per plant. The second factor is mycorrhiza biofertilizer consists of three levels M0 : control, M1 : 20 g, M2: 40 g per plant. The parameters observed were the increase in plant height, the increase i…
Restrictions on soil dystrudepts are related to the low content of fertile elements and affect soil fertility for plant growth and production. The addition of Mineral Polyhalite is expected to increase the supply of harvest for plants when combined with KCl. In Petapahan Village, Tapung District, Kampar District, Riau Province, a people's palm coconut farm with Dystrudepts was the site of the r…
Increasing the production of chili plants in Indonesia continues to be developed, one of which is by using inorganic fertilizer. However, the excessive use of inorganic fertilizers by farmers in Riau Province is quite worrying about the decline in soil quality. Based on this, this research aims to obtain the best combination of giving doses sludge compost and biological fertilizer enriched with…
Banana peels not be used optimally, so they need to be used as fertilizer by composting. Compost is one of the most natural fertilizers that is widely used for agriculture. Compost fertilizer or often called compost has become an alternative that has been developed recently considering that soil conditions are starting to deteriorate.This research was carried out at the Soil Science Laboratory,…
This study set out to ascertain the factors that influence the interaction between Oil Palm Empty Bunches (OPEB) compost and nitrogen fertilizer, as well as the optimal combination dose for enhancing the development and yield of upland rice plants (Oryza sativa L.). The study was carried out at the Faculty of Agriculture, Riau University. This study was conducted from May to September 2023. Thi…
The development of paludiculture plants such as sago as a vegetative restoration can maintain the natural properties of tidal land that is damaged when drained. This study aims to determine the characteristics and suitability of tidal land for sago development. The research method used is a soil survey.
