ABSTRACT Palm oil is the largest vegetable oil-producing plantation crop in the world. Riau Province is one of the centers of palm oil production in Indonesia. One of the causes of the decline in palm oil production is stem rot disease caused by the pathogenic fungus Ganoderma spp. The aims of this study were to determine the effect of inoculation of Ganoderma spp. isolates from palm oil p…
ABSTRACT The rhizosphere is a habitat for various kinds of soil microorganisms, both beneficial and parasitic. The availability of nutrients released by root exudates is an important reason for the presence of these microorganisms, besides the rhizosphere is also an entry point for soil pathogens. This study aims to obtain, select and test the rhizosphere bacteria which have the antagonist…
ABSTRACT Plant roots are one of the factors that determine the growth, development, and yield of soybean plants. This is because roots are the first organ to respond to soil conditions. This study aims to determine genetic variation, heritability values, and correlations between characters on the rhizobox scale and field scale of several soybean genotypes. This research was conducted at Po…
