PRODUCTIVITY OF FOUR RICE VARIETIES AND PEST DISEASES WITH THE APPLICATION OF ENVIRONMENT FRIENDLY AGRICULTURE TECHNOLOGY IN JAKEN, PATI, CENTRAL JAVA

Abstract

Pest and disease attacks are factors that affect the production and productivity of rice plants. The approach of environment friendly agriculture technology is expected to be able to overcome the problems of pests and diseases and increase the production and productivity of rice plants. This study aims to determine the productivity of four rice varieties and the intensity of pest and disease attacks on the application of environment friendly agriculture technology. This research was conducted in Jaken, Pati district, Central Java, from November 2019 – March 2020. This study used a purposive sampling method with a Randomized Group Design (RGD). Rice variety is the single factor in this study. The rice varieties used consisted of Inpari 32, Cigeulis, Inpari 43 and M400. The components of environment friendly agriculture technology used are the use of biochar-compost (biocompost), charcoal-coated urea or biochar, and the use of biopesticides as pest control. Observations were made on growth, productivity and intensity of pest and disease attacks. The results showed that the varieties produced high productivity were Inpari 43 (4.91 t ha-1) and Inpari 32 (5.83 t ha-1). The high pest attack was the yellow rice stem borer (89.47%) on the M400 variety and the brown planthopper (7.69%) on the Cigeulis variety. The intensity of blast disease and bacterial leaf blight were highest at 14.97% and 5.99%, respectively, in the M400 variety.
