The purpose of study is to know the effect of interaction of phosphorus fertilizer and synthetic zeolite and the main influence of phosphorus fertilizer and the main influence of synthetic zeolite on the growth and yield of upland rice in Ultisol. The research was carried out experimentally in factorial form, using a completely randomized design ( CRD ) . The first factor is phosphorus fertiliz…
Tomato production in Riau has been declining because the varieties of tomatoes planted have not been able to adapt well in the lowland. The aim of this research is to find out the value of correlation, the direct and indirect influence between the character of the resulting components on the genotype of tomatoes. The research used a randomized block design (RBD) with eight genotypes consisting …
This study aims to determine the inheritance system of various agronomic characters and yield components of soybean plant populations, so that it can be determined which characters are well used to conduct indirect selection on various yield components in a soybean population. This study used a randomized block design (RBD) with treatment is a variety consisting of 13 varieties of soybeans and …
The low production of tomato plants in Riau is partly due to the fact that tomatoes have not been able to adapt to the lowlands. Planting superior tomato varieties that are lowland tolerant is needed to increase tomato production. The purpose of this study was to determine the diversity component, heritability value, genetic correlation and selection response of yield characters of eight tomato…
The decrease in tomato production that occurred in Riau Province was caused by several factors, including the cultivated tomato varieties that have not been able to adapt well, especially in the lowlands. It is needed to conduct research related to tomato cultivation, by assembling superior tomato varieties in the lowlands. The purpose of this study was to determine the genetic correlation to d…

Kelubi is a fruit that has sour taste and cannot be consumed fresh. One alternative to increase adding economic value of kelubi fruit is through process it into a powdered drink. This study aimed to obtain the best concentration of maltodextrin to the characteristics of kelubi powder drink. The research was conducted experimentally using a completely randomized design with four treatments an…
Shallot (Allium ascolonicum L.) is one of the important crops for the indonesian people. The low productivity of shallots in Riau is caused by various factors, one of which is caused by disease. One of the diseases in shallots is moler disease caused by the fungus Fusarium oxysporum Schlecht. The common control for F. oxysporum is by using chemical fungicides. …
