Abstract

The species of egg parasitoid in rice bug is necessary to know to be used as biological agent in the field. The research aimed to determine spesies of parasitoid, diversity index, parasitization level and parasitoid mortality which found in rice bug eggs in rice fields in West Sumatra. Purposive random sampling was used in this research for determining the sampling locations. Collecting eggs sampling was conducted for 1 km along transect line in sampling location. The collected eggs of 12 sampling locations then observed and identified in Laboratory of Insect Bioecology, Faculty of Agriculture, Andalas University. The result showed that the kind of egg parasitoid found in the field were Hadronotus leptocorisae and Ooencyrtus malayensis with each parasitization level were 22.3 ± 11.1 % and 4.2 ± 5.3 %, each the mortality were 57.8 ± 26.4% and 30.6 ± 37%, the diversity of egg parasitoid was low with the index 0.3858 Based on Shannon-Wienner.

Abstract

Jorong Ganting Taram farmers cultivating rice using conventional systems, production is still low, namely ± 4.5 tons h-1 . The Ganting Malay Farmers Group is a pioneer to change the SRI method of rice cultivation with cow urine POC technology with EM4 activator and indigenous microbes. The purpose of implementing this community service is to increase rice production at a lower cost so as to increase yields and farmers' opinions. Activities are carried out in three ways: a) Socialization and Counseling, b). Training to make cow urine POC, c) SRI method rice demonstration plot with cow urine POC. The results of the socialization and extension of rice using the SRI and POC methods of cow urine with EM4 activator and indigenous microbes gave good value to the understanding of the material and the ability to implement. The training on making cow urine POC and applied to the rice demonstration plot using the SRI method increased the growth and yield of rice compared to the conventional system. Conclusion: SRI method of rice cultivation with cow urine POC technology increases rice yields and farmers' income.

Abstract

Differences in location and rhizosphere cause differences in species diversity and population of Arbuscular Mycorrhizal Fungi (AMF). In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. This study aims to determine the presence and number of spores as well as to determine the morphological characteristics of AMF originating from the rhizosphere of several horticultural crops in the agricultural land of Payakumbuh State Agricultural Polytechnic. The method used in this research is descriptive exploratory method by means of purposive sampling for soil sampling. While the stages of this research include: taking and collecting data in the field, determining the point of location for soil sampling, taking soil samples, analyzing soil properties in the laboratory, isolating AMF spores and identifying AMF spores morphologically. The conclusions of this study are 1) The population of AMF spores in horticultural land is high. The highest spore population was found in soil samples of the root area of shallot plants (556 spores per 10 g of soil), while the lowest number of spores was in soil samples of eggplant root areas (271 spores per 10 g of soil), 2) AMF exploration in several horticultural crops in the agricultural land of the Payakumbuh State Agricultural Polytechnic, based on morphological identification (shape, color and size), the AMF found consisted of three genera, namely Glomus sp, Gigaspora sp, and Scutelospora sp.
