ABSTRACT Okra is currently gaining popularity among the public. Okra plants are not yet widely cultivated in Riau Province, which results in low okra production. Consequently, okra cultivation has good potential due to increasing market demand. This research aims to determine the interaction effect of Bokashi fertilizer and NPK fertilizer application, as well as the main factors of each treatm…
ABSTRACT Soybeans (Glycine max L. Merrill) are one of the most important food crops, rich in plant-based protein. However, domestic production does not yet meet national demand, due to various factors such as land conversion and low soil fertility. One approach is to incorporate organic materials like biochar, which is the pyrolysis product of agricultural waste such as rice husks, containing …
ABSTRACT The study aims to compare the diversity of soil macrofauna and mesofauna on various land covers on the University of Riau campus. The research location consists of 5 types of land cover including the Arboretum of Riau University, grass land cover, oil palm land cover A (Marihat), experimental garden of the Faculty of Agriculture, Riau University, and oil palm land cover B (Lonsum). Ma…
ABSTRACT Mangosteen plant (Garcinia mangostana L.) is one of fruticulture plants in horticultural plant groups which is mostly rare infected by plant diseases. The data on disease incidence and intensity have been rarely reported so far. This is assumed that the plant has natural resitance systems derived from secondary metabolites compounds such as triterpene, mangostine, tanein, resin, antos…
ABSTRACT The aim of this research is to select and obtain isolates of rhizosphere fungi from mangosteen plants which have high antagonism activity against Phytophthora palmivora, the cause of stem base rot disease of siamese citrus plant and to identify to the genus level. The study was conducted at the Laboratory of Plant Disease, Faculty of Agriculture, University of Riau, Pekanbaru. The res…
ABSTRACT Soybean (Glycine max L.) is the main food crop after rice and corn. One of the problems faced in soybean cultivation is the attack of armyworms (Spodoptera litura). Yield losses due to pest attacks can reach 80% or even crop failure if not controlled. Papaya leaf (Carica papaya L.) botanical pesticide can be a safe alternative for controlling S. litura. This study aims to obtain an ef…
ABSTRACT The development of upland rice in Indonesia is very important as a solution for food security, especially in areas that do not have adequate access to irrigation water. Upland rice is a rice variety planted on dry land, with major challenges such as limited soil nutrient content and low productivity. Efforts that can be made to cultivate upland rice on dry land are by using organic ma…
ABSTRACT Corn (Zea mays L.) in cultivation has obstacles, namely pest attacks in the field. The main pest that often attacks corn plants is Spodoptera frugiperda J.E. Smith. Soursop plants (Annona squamosa L.) can be used as botanical pesticides to control Spodoptera frugiperda. The study aims to obtain an effective concentration of organic extract of Annona squamosa leaf flour against the mor…
ABSTRACT This study aims to determine the best chlorox sterilization in the cultivation of Dendrobium sp. orchids in vitro. lorox with a concentration of 3% and 5% is the best concentration for the growth of Dendrobium sp. orchid plantlets with a survival rate of 50%.Dendrobium sp orchid subculture should use chlorox with a concentration of 3%, this aims to prevent damage to plant tissue, in a…
ABSTRACT The purpose of study is to know the effect of Trichocompost and NPK fertilizer interaction, the main effect of Trichocompost factor and the main effect of NPK fertilizer factor, as well as to find the best combination of Trichocompost and NPK fertilizer treatments on the growth and production of soybean plants. Studies using factorial trials 4 x 4 by 3 replication, with two factors of…
ABSTRACT This study aims to determine the effect of the best concentration of the combination of BAP with tomato extract on the growth of epicotyl explants of Citrus nobilis Lour. and to support the growth of Citrus nobilis Lour. plantlets from Kampar in vitro.

ABSTRACT This study aims to characterize peat maturity based on the typology of peat domes in Dayun Village, Siak Regency. The peatlands in this area exhibit distinct dome typologies, namely the dome peak, back, and foot, which significantly influence the physical and chemical properties of the soil, including ash content, C-organic content, C/N ratio, and fiber content. The study was conducted…
ABSTRACT Corn is the third most important food crop after rice and wheat in Indonesia. The decrease in corn production in Riau Province is caused by several factors, one of which is the presence of weeds.
