The purpose of this study was to determine genotypic performance of M2 generation of mung beans resulting from gamma ray radiation compared to parents. Mung bean seeds from Kampar as M0 population and M2 generation from gamma ray radiation, were planted in the experimental station of the Faculty of Agriculture, University of Riau by using completely randomized design. The study was conducted by…
Mung beans are legumes that known and cultivated in Indonesia. This plant is an important commodity. Utilization of oil palm processing plant sludge is still not optimal, therefore sludge can be utilized as an alternative supply of nutrients for the development of green bean plants. PKS sludge is the waste from the byproduct of the processing of fresh fruit bunches (FFB) in the form of solid ob…
Sitophilus zeamais M. is a storage pest that attacks corn kernels in the storage. Pest control strategies in storage which are often carried out are chemicals, namely insecticides in the form of fumigants. One of them is using plant-based insecticides. Babadotan is a plant that can be used as a botanical insecticide. The aim of this research was to obtain an effective dose of babadotan flour to…
Oil palm is an important plantation of agriculture. Oryctes rhinoceros is a main pest that attack on oil palm from pra nursery to production. Alternative control that can be develoved is using plants as natural insecticidae. Paitan (Tithonia diversifolia) is one of plants that used as natural insecticide. The research aimed at determining consentration of paitan (Tithonia diversifolia (Hemsley)…

This study aimed to determine the main effect of the application of oil palm shell ash (OPSA), Rhizobium sp., interactions in peat soils on the formation of root nodules and growth of acacia seedling and determine the best combination of treatments that resulted the best growth of acacia seedling in peat soils. This research was conducted using CRD method 4x2 with 3 replications. The first fact…
Propagation of cuttings using plant branches can be grown in to new plants. The advantage of propagation by cutting is that the new plant produced have the same properties as the parent. The research aims to determine the effect of interaction of Rootone-F and the cutting plant material for the growth of lime cutting and to get the best concentration of Rootone-F and the plant material for cutt…
Shallot productivity can be increased by taking into account the right fertilizer factor and the potential of the seeds used. The study of potassium and manure dosages and seed size were carried out to get the best treatment in increasing growth and yield. The study was conducted in the Experimental Garden of the Faculty of Agriculture, University of Riau, from February to April 2019, using a d…
Productivity of shallots can be increased through the use of seeds derived from seeds. However, seed growth in the field requires effective growth requirements and avoids full sun exposure. For this reason, it is necessary to study the shade time and determine the planting distance that can support the growth of seeds in the hope of obtaining the best shade time and planting distance to obtain …
Acacia crassicarpa is one of the industrial tree plantations that planted in Riau Province. Ganoderma sp. causes root rot disease is the main disease on acacia plantations. One of the control strategies for this problem is using biological control agent such as endophytic bacteria. The research aims to determine the antagonistic activity and get the best isolate of endophytic bacteria as bi…
