ABSTRACT Soybean (Glycine max L.) is one of the important food commodities in Indonesia. Soybean demand continues to increase every year. Riau soybean production in 2019 was 583.5 tons and in 2021 soybean production decreased dramatically to 390.48 tons. The decline in soybean production is due to land conversion and low soil fertility. The low level of fertility in the soil can be overcome by…
ABSTRACT The productivity of upland rice on sub-optimal land such as podzolic is low and can be increased through the application of rice husk zeolite and K fertilizer. This study aims to study the combination of rice husk zeolite and K fertilizer and the effect of each of them to the growth and yield of upland rice (Oryza sativa L.) on podzolic media (Ultisol). This research was conducted exp…
ABSTRACT The productivity of upland rice is relatively low, generally planted on sub-optimal. Productivity can be increased through technological innovation by adding rice husk zeolite and P fertilizer. This research aims to determine the combination of giving rice husk zeolite and P fertilizer and their respective effects on the growth and yield of upland rice. The research was conducted at t…
ABSTRACT The purpose of this study was to increase the production of eggplant (Solanum melongena L.) with the application of oil palm ash and TSP fertilizer. The research was conducted in the experimental garden of the Faculty of Agriculture, Riau University. This research was conducted during four months from February to May 2022. This research was conducted experimentally in the form of a 4 …
ABSTRACT Mung beans (Vigna radiata L.) is the most important legume crops after soybeans and peanuts so that the needs for mung beans will increases. Efforts that can be made to increase production on marginal land include optimizing fertilization. This study aims to determine the effect of giving goat manure and getting the best dose in increasing the growth and production of mung bean pl…
ABSTRACT Cocoa is an important plantation crop for the national economy and a source of foreign exchange. The problem faced in large-scale cocoa nurseries is the limited top soil as a planting medium in polybags, One of them is Ultisol. Ultisols are widespread in Indonesia and are classified as marginal, requiring efforts to improve soil fertility. The purpose of this study was to investigate …
ABSTRACT Chili productivity in Riau is still low due to several factors, namely the condition of the land where most peatlands have low soil fertility and pH. Not all plants are able to grow and develop properly. Through plant breeding activities, a selection is made that is able to overcome these problems. The aim of the researchwas to estimate the genetic parameters of the quantitative chara…
ABSTRACT The aim of the research was to obtain the best combined dosage of NPK fertilizer and organic fertilizer for the growth and production of shallot (Allium ascalonicum L.) so as to reduce the use of inorganic fertilizers. The study used a non-factorial Completely Randomized Design (CRD). The treatments used were: 100% NPK + petroganic fertilizer; 100% NPK fertilizer + solid compost; …
ABSTRACT Shallot is one of the vegetable commodities that has long been intensively cultivated by farmers. Onion production in Riau Province has decreased by 263 t from 507 t. The cause of low production is the condition of agricultural land which is marginal land. This study was conducted to determine the interaction of the combination of cabbage waste compost and cow blood meal, the trea…
ABSTRACT Chili plants have high economic value. Increasing chili production in Riau can be done using peatlands, but peatlands can cause less than optimal plant growth. Efforts to improve chili production can be performed through plant breeding efforts. Selection is an important step in a plant breeding program. Selection is divided into two based on the character of the purpose of the selecti…
ABSTRACT Chili is a plant that has great prospects in agriculture. Chilies have the potential to be planted on peatlands. One of challenges is that there are few plant kinds that are adapted to peatlands. Plant breeding initiatives are used to find superior cultivars that are tolerant of peatlands. Selection can be done through genetic parameters, such as diversity and heritability components.…
ABSTRACT Corn (Zea mays saccharata Sturt.) is the second staple food in Indonesia after rice, because it has almost the same carbohydrate, protein and calorie content as rice. Pests that attack corn is the corn earworm (Helicoverpa armigera Hubner). Corn crop losses due to H. armigera attack in Indonesia reached 40% so that pests need to be controlled. The control of H. armigera Hubner can be …
ABSTRACT Oil palm (Elaeis guineensis. Jacq) is a leading plantation commodity in Indonesia. The main problem in palm oil cultivation is the attack of the nettle caterpillar (Setora nitens. Walker). S. nitens attack can of producing plants and can reduce production by about 69%. The use of entomopathogenic bacteria Streptomyces sp. can be alternative to controlling nettle caterpillar S. nitens …
ABSTRACT The entomopathogenic fungus Beauveria sp. is a fungus that can cause disease in insects and soil born because it naturally occurs in the soil. Beauveria sp. has a beauvericin toxin which interferes with the function of the hemolymph and nucleus of the host insect cell. This study aims to obtain the effective concentration of local isolate Beauveria sp. in controlling cacao pod-sucking…
ABSTRACT Oil palm is the main plantation crop in Riau Province. Oil palm cultivation is inseparable from nettle caterpillar pest attacks. Pest control generally uses synthetic insecticides so that alternative controls are needed using natural enemies such as the predator Eocanthecona furcellata. The use of predators requires a large number, so it needs breeding efforts but is constrained by th…
ABSTRACT Rhinoceros beetle (Oryctes rhinoceros) is the main pest attacking oil palm plantations in Indonesia. The aim of the study was to obtain the growth of O. rhinoceros larvae on various types of compost made from several organic materials. The study was carried out experimentally using a completely randomized design with 8 treatments and 4 replications. Treatments in the study were Palm O…
ABSTRACT Mung bean (Vigna radiata L.) is a food that is widely consumed by Indonesian people. Mung bean production in Riau Province is decreasing every year, this can be seen from the data from the Riau Province Food Security Service. The decline in mung bean production in Riau Province was partly due to land conversion so that sub-optimal land has the potential to be used as mung bean cultiva…
