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…
