The low productivity of soybeans in Indonesia, especially in Riau Province, is due to suboptimal cultivation techniques and a decrease in nutrient levels in the soil. Applying balanced fertilization is one of the appropriate cultivation techniques for increasing the nutrient content of the soil and providing nutrients for soybean plants. The aim of this research was to determine the effect of t…
Rice (Oryza sativa L.) is a staple food crop that produces rice as the staple food for most of the Indonesian population. The average productivity of upland rice in Indonesia is still relatively low, but it has the potential to be cultivated on marginal dry land (Ultisol) which has various limiting factors, both chemical and physical. Improvement of these limiting factors can be done by adminis…
The need for sweet corn increases along with the increase in population. Increasing corn production can be done by using cow biourine and phosphorus fertilizer. This research aims to determine the interaction and combination of giving cow biourine with phosphorus fertilizer on the growth and yield of sweet corn plants. This research used a completely randomized design (CRD) consisting of two fa…
This research used a factorial completely randomized design (CRD) consisting of two factors. The first factor is Empty Fruit Bunch (EFB) compost with three levels, namely T0= no EFB compost, T1= 10 t.ha-1 EFB compost, T2= 15 t.ha-1 EFB compost. The second factor is the provision of KCl fertilizer with three levels, namely, K0= without KCl fertilizer, K1= 100 kg.ha-1 , K2= 150 kg.ha-1 . The pa…
Spodoptera litura F. one of pest soybean plants. Control using local entomopathogenic fungi Cordyceps militaris is an effort to control S. litura using environmentally friendly materials so as to reduce synthetic chemical pesticides. C. militaris has a cordycepin toxin that generally attacks larvae and pupae of the order Lepidoptera. The research was aimed to obtain the concentration of local …
This study aims to determine the effect of the interaction of Kinetin and NAA on the growth of epicotyls of kasturi orange (Citrus microcarpa), and to obtain a combination of Kinetin and NAA, as well as the concentration of Kinetin or NAA that supports the growth of kasturi orange explants. This research was conducted at the Biotechnology Laboratory, Faculty of Agriculture, Riau University, Pek…
The fall armyworm (Spodoptera frugiperda J.E. Smith) is a major pest of maize crops. Biological control using local Cordyceps militaris L. Fries can control S. frugiperda. C. militaris has cordycepin toxin which generally attacks larvae and pupaeofthe order Lepidoptera. Thestudyaimed to obtain the concentration of local entomopathogenic fungi C. militaris as a bioinsecticide against the mortali…
Vermicompost (worm castings) is a fertilizer that plays a role in increasing soil fertility and providing nutrients for plant growth. NPK fertilizer contains macro nutrients that plants need in their growth process. This research was carried out at the Technological Islamic Boarding School Land, Kulim, Tenayan Raya District, Pekanbaru, Riau and was carried out for 5 months. Research Method This…
Purple eggplant (Solanum melongena L.) is a seasonal plant that belongs to the Solanaceae family. Every 100 g of fresh eggplant contains water, energy, carbohydrate protein, fat, calcium, phosphorus, sodium, potassium and vitaminC. The market potential of eggplant can be seen from the price that is affordable by the community so that it opens up greater opportunities for farmers. This research …
Efforts can be made to increase rice production by developing upland rice cultivation and increasing its productivity, because upland rice can be cultivated on marginal dry land such as Ultisol. The technology that can be applied to increase this is the provision of a composition of rice husk zeolite, fish liquid organic fertilizer (LOF), N and P fertilizer. The aim of the research is to obtain…
Cultivating upland rice on dry land (Ultisol) is one way to increase rice production in Indonesia.
