APPLICATION OF SEVERAL TYPES OF REFUGIA AND INTERCROPPING PATTERNS OF TOPO ONIONS, CHILI AND TOMATOES ON SUBOPTIMAL DRY LAND

Abstract

Global warming can have an impact on the environment and plants. Prolonged global warming can increase drought, one of which is a lack of water, both in land and plants. Plants that experience drought can increase pest and disease attacks. For this reason, it is necessary to carry out research on the application of several types of refugia and intercroping patterns for topo onions, chilies and tomatoes on suboptimal dry land. The aim of this research is to find out how much influence the types of refugia have on top onion, chili and tomato plants in dry land. To determine the effect of the intercropping system on topo onions, chilies and tomatoes in dry land. The research was carried out in West Halmahera Regency, North Maluku Province. The design used was a split plot design with three replications. The first factor, as the main plot, is the refugea consisting of R1: Aster Flowers and R2: Gemitir Flowers (chicken taek). The second factor is a subplot consisting of I1: Topo onions, I2: Chilies and I3: Tomatoes. The morphological variables observed were plant height, stem diameter, number of leaves, number of fruit, fruit diameter and fruit weight. Data were analyzed using SAS, if there was a significant effect, it was continued using the Duncan test at the 5% level. The results of the research showed that the use of refugia plants, both R1 and R2, significantly affected plant height, stem diameter, number of leaves, number of fruit, fruit diameter and fruit weight compared to plants that did not use refugea treatment. Plants using the intercropping system provided by refugea plants can increase crop production and reduce pest attacks. This shows that dry land can be used as competent agricultural land.
