ABSTRACK The need for corn in Indonesia continues to increase and efforts are needed to increase corn production, one of which is by extensification. With extensification, untapped lands such as marginal lands Dystrudepts began to be used. Dystrudepts is infertile soil, the solution to the problem with Dystrudepts is chalk. However, Riau does not have a limestone deposit. Another alternati…

ABSTRACT Palm oil is one of the plantation commodities that has an important role in the economy in Indonesia. One of the causes of the decline in oil palm production in Raiu Province is stem rot disease (BPB) caused by the pathogen Ganoderma spp. This study aims to examine the morphological and physiological diversity of Ganoderma spp. from smallholder oil palm plantations in Kampar Regen…
ABSTRACT Rainwater harvesting is a technique of using water in aquaponic agriculture. Aquaponics is an agricultur that raises plants and fish in the same container. Lettuce is a leafy vegetable plant that has high economic value. However, lettuce cultivation has not developed due to limiting factors such as the availability of water and growing media. Peat is soil that has low fertility fo…
ABSTRACT This study aims to determine the appearance of the agronomic characters of 16 tomato genotypes and the kinship based on the similarity between the tomato genotypes tested in the lowlands. The research was carried out for 6 months at the Experimental Garden and Plant Breeding Laboratory, Faculty of Agriculture, Riau University, Pekanbaru. The study used a randomized block design co…
ABSTRACT Productivity of chili (Capsicum annuum) in Riau is still low due to the condition of the land which is mostly peatland. Producing superior varieties of peatland tolerant chilies through plant breeding requires specific selection criteria. The purpose of this research was to obtain information about the close relationship between quantitative characters and yield characters and the…
ABSTRACT Chilli is one of the important horticultural crops. Productivity of chilli in Riau has not been maximized because most of the land is peatlands, so it is necessary to assemble an adaptive chilli variety on peatlands. So, the purpose of this research was to obtain information about the qualitative and quantitative characters of the genetic diversity of 20 chili genotypes and to ana…
ABSTRACT Acacia is generally propagated by cuttings, shoots for genetic preservation and production of large numbers of seedlings. The problem with planting acacia is when seeding cuttings. The critical period for cutting cuttings is when the cuttings have not yet taken root, while the formation of shoots requires active growth of the roots, so that during this period the number of cutting…
ABSTRACT The quality of oil palm seeds produced is influenced by the planting media used. One of the alternative media that can be used for oil palm nursery media is Ultisol subsoil. Subsoil soil has a lower fertility rate than topsoil. Therefore, OPEFB and NPK compost were added which were expected to increase the fertility of Ultisol subsoil. This study aims to determine the effect of th…
ABSTRACT This research aims to test and obtain isolates and a consortium of rhizosphere fungi from chili plants to control onion seed-borne pathogenic fungi of onion plant.
