Abstract

Germination  problems in the commerce in general are the seeds will experience a period save on condition of sub optium.The seeds that have high viability and vigor which is expected to be passed on to seed derivatives that are genetically seed quality can be maintained. The study aims to determine the diversity of physiological seed quality of 20 genotypes of papaya collection Tropical Fruit Research Institute. Research conducted at the KP Sumani Balitbu Tropika 2015. Materials: 20 genotype papaya seeds. Research using a randomized block design with three replications treatment of 20 genotypes of papaya. Results of the study showed germination of 20 genotypes of papaya tested ranged from 33-93%, vigor index among 11-81%, the maximum growth potential of among 16-100%, and the plant fresh weight ranges from 0.5 - 15 g. Genetic diversity germination, the seeds of papaya is very high. Characters germination, vigor index and wet weights, the character is inherited as too high the heritability

Abstract

One of indicator of soil fertility is the population level of microbial in the soil. This research aims to determine the number of bacterial populations in the soil on yhe Larangan Adat Rumbi Forest with different levels of depth. This research has been carried out on January-February 2015 in the Laboratory of Pathology, Entomology and Microbiology, Faculty of Agriculture and Animal Sciences of State Islamic University of Sultan Syarif Kasim Riau. The method that was used namely observation method by taking soil samples on the Larangan Adat Rumbio Forest then calculated the number of colonies of bacteria and analyze the morphology of the bacteria that was obtained macroscopically and microscopically. Parameters measured were pH of soil, the population of bacteria, bacterial morphology, gram stain, and bacterial cell shape based on soil depth of 0-10 cm, 11-20 cm, 21-30 cm. Observations carried out two stages macroscopic and microscopic observation. The results showed the soil pH on the Larangan Adat Rumbio Forest was 4,11. Total population of bacteria at depth of 0-10 cm namely 3,0 x 109 CFU, then at a depth of 11-20 cm namely of 2,2 x 109 CFU and at depth of 21-30 cm namely 1,6 x 108 CFU. The Results of purification of culture was obtained six isolat two coccus and four bacil consisting of five gram negative bacteria and one gram positive. Need to do further research on bacteria identification to genus or species level.

Abstract

The aim of research to determine the effect of compost main pod husks and dolomite as well as their interaction on the growth of cocoa seedlings in media ultisol. Research conducted at the Experimental Farm, Faculty of Agriculture, University of Riau from November 2015 until February 2016. Research in the form of factorial experiment using completely randomized design (CRD). The first factor pod husks compost comprises four levels (0, 75, 100 and 125 g / polybag) and the second factor dolomite consists of three levels (0, 10, and 20 g / polybag), each combination treatment was repeated 3 times. Parameters measured were plant height, leaf number, stem diameter, and leaf area. Each parameter the observed data were statistically analyzed using analysis of variance and test of Duncan's New Multiple Range Test (DNMRT) at 5% level. The results showed the effect of compost pod husks dose of 125 g / polybag significantly increased plant height, stem diameter, number of leaves and leaf area while dolomite dose of 20 g / polybag no real effect except leaf area compared with no treatment. Interaction pod husks compost dose of 100 g / polybag and dolomite dose of 20 g / polybag increase stem diameter, number of leaves and leaf area significantly compared without compost pod husks and dolomite but less tangible than other combinations.

Abstract

The Land between row of immature rubber period has a potential to produce sweet sorghum. This sorghum is one of high value commodities for food and energy security due to its wide adaptation. The objective of this research were to study the effect of rubber+sorghum intercropping system on the growth of immature rubber trees and to study some agronomic parameters of sorghum and production of sweet sorghum as rubber intercrops. The experiment was conducted at the Sembawa Research Station from June to October 2013. The experiment was carried out as a single factori using Randomized Block Design with three replications. The treatment were 3 varieties of sorghum i.e: Pahat, Kawali and Mandau. Observation of rubber trees was conducted using simple random sampling method, comparing the rubber trees growth of sorghum intercropping system with the rubber trees growth of monoculture system. The results showed that sorghum had a positive effect on the growth of rubber tree IRR 118. Furthermore, fresh stem weight (37.11 t/ha), juice yield (1.80 t/ha), and grains yield (2.69 t/ha) of sweet sorghum Kawali higher than that of the varieties tested. The Kawali has a high potential to produce a biofuel because it had a highest fresh stem weight and juice content.

Abstract

ABSTRACTThis research had been conducted from December to March 2015 at Horticultural Seed Center, Marpoyan, Pekanbaru. The study aimed to determine the effect of the type of rootstock and the storage period of buds as well as the interaction between both of them towards  its growth. This study was conducted experimentally by using completely randomized factorial design (CRFD) consisting of two factors and seven replications. The first factor was type of rootstock (B1: Japanese Citroen, B2: Rough Lemon) and the second factor was storage period of buds (M0: directly grafted, M1: 1-day storage period, M2: 2-day storage period, M3: 3-day storage period). Parameters measured were growth percentage of buds, bud burst time, length of buds, number of leaves and diameter of buds. The results showed that the Rough Lemon rootstock had a significant effect on the number of leaves, length of buds, bud burst time, diameter of buds and equally effect on the growth percentage of buds. Storage period of the buds did not significantly affect the growth of the grafted Siam Madu citrus seedlings.. The interaction between the type of rootstock and the storage period of buds only occurred in the bud burst time only.

Abstract

Tea Shoot roller (Cydia leucostoma Meyrick) is one potential pests that attack tea shoot, mainly on the new tea shoot after prunning, it caused plant growth becomes stunted. One of control that can be done is by application of insecticides. To determine the effectiveness of insecticide Acetamiprid, the trial has been conducted at Block A7, Gambung field trial, Kabupaten Bandung, during ± 3 months, from October up to December 2016. The trial was designed in Randomized Complete Block Design (RCBD) with five treatments and four replications. The treatment tested covered insecticide Asetamiprid 30% at 1; 0.75; 0.50; 0.25 l/ha and control. The insecticide was sprayed six times using knapsack sprayer one day after plucking, with one week interval. Tea shoot roller attack intensity was observed weekly at the time of plucking. Shoot production, phytotoxicity, as well as rainfall were also observed as a supporting data. The results showed that after three times of spraying, insecticide Asetamiprid 30% at all formulation doses tested could effectively suppress the attack intensity of tea shoot roller. The last observation result, after six times spraying, revealed that the average efficacy level relatively high, i.e. 73,24%. Therefore, for controlling tea shoot roller on tea it could be recommended the use of insecticide Asetamiprid 30%.
