Abstract

Seed Quality Testing Several Types of Horticultural Crops Circulating in Bali This study aims to determine the physical quality, viability, and vigor seeds of several types of horticultural crops those circulating in Bali. This research was conducted at Breeding and Seed Technology Laboratory and Plant Disease Laboratory of Udayana University Faculty of Agriculture, which lasted from February to April 2015. The method used is seed testing method with duplo system and using T-Test with three replications. The types of seeds that are tested for their quality consist of seven species: mustard, long bean, eggplant, ercis, cucumber, cayenne, and cabbage. The variables observed were physical quality (moisture content), viability (seed germination), and vigor (synapticity of seed growth). The results showed that the seeds of some horticultural crops circulating in the market in Bali have a pretty good quality. This can be seen from the physical quality test of seeds in the form of moisture content, almost all seeds have a relatively safe water content for storage. The result of seed quality test of percentage of seed germination gain between 90.33% - 97.33% in laboratory test is very good because it is above the standard germination value. The result of the simultaneous vigor test grew up to 59.00% - 69.00% is a good enough vigor value because it is at a level above 50%.

Abstract

ABSTRACT Population Abundance and Rice Stem Borer Attack on Rice in Tabanan Regency Tabanan Regency is rice production center in Bali Province. In terms of rice production in 2009 Tabanan Regency can produce 242.000 tons of grain per year, still rice production in the field has many obstacles, one of which is the rice stem borer can attack plants in the vegetative phase and the generative phase. It is necessary for the proper control measures, through an ecological approach and monitoring system to control rice stem borer in the field. The pattern of population growth which include diversity and population dynamics of the rice stem borer in the field, it is helpful for decision-making in determining control strategies appropriate to the circumstances on the ground pests. Found four species of rice stem winches in Tabanan Regency. The fourth species is Scirpophaga incertulas Walker, Sesamia inferens Walker, Chilo suppressalis Walker, and Chilo polychrysus Meyrick. S. incertulas is the dominant species found at each altitude. Rice stem borer species diversity is low <1.5, The value of the index of similarity between the study site reached a value of 86 % and 100 % . The structure of the rice stem borer populations between egg , larva , pupa and imago fluctuate every stage of plant development and reached its peak at the age of  rice 2 Weeks after planting egg stage , 4 Weeks after planting on larval and imago , 5 Weeks after planting at the pupa stage. The highest population abundance indicated S. incertulas at an altitude <250 (0-250) masl (meters above sea level), with the highest attack percentage at a height <250 (0-250) masl.   Keywords: Rice stem borer, species diversity, abundance, percentage.

Abstract

The Influence of Fipronil 50 g/l Against Population Abundance and Parasitization Level of Egg Parasitoid of Yellow Rice Stem Borer in Tabanan District Yellow rice stem borer, Scirpophaga incertulas Walker (Lepidoptera: Pyralidae), is one of the important pests of rice plants in Indonesia. Efforts to control those pests are using a lot of synthetic insecticide in the field, meanwhile egg parasitoid is considered to have an important role in the control those pests in nature. The aim of this research is to know the influence of insecticide with active ingredient Fipronil 50 g/l to population abundance and parasitization level of egg parasitoid of yellow rice stem borer. The research was arranged by using randomized block desing with six treatments and four replicates. The results showed that T. Schoenobii parasitoid is the most dominant parasitoid among other types of parasitoids and its diversity is low that is <1,5. Pesticide with active ingredient Fipronil 50 g/l has significant effect on population abundance and parasitization level egg parasitoid of yellow rice stem borer. The highest population abundance was on control and lowest in treatment dose 1.50 cc/l. The highest parasitoid parasitization rate in Tabanan is (19.70%). The parasitization rate was decrease with the increase of tested insecticide dose, so the lowest number was at 1.50 cc/l treatment with percentage (8.62%).
