Abstract

Brown rice is recognized as a food commodity with high nutritional value and considerable health benefits for humans. However, its cultivation remains relatively limited in popularity and is often associated with low productivity, particularly when grown on marginal lands such as coastal areas affected by high salinity. This study aimed to evaluate the adaptive responses in growth and yield performance of several local brown rice genotypes under salinity stress conditions in the coastal region of Pantai Cermin, Serdang Bedagai Regency, North Sumatra. The research was conducted using a non-factorial Randomized Block Design (RBD) involving eight local brown rice genotypes: Beras Merah, Sidrap Merah, Kelik-3, Mesuji, Sijior, Sipenget, Meulaboh, and Si Tappe. The observed parameters included plant height, number of leaves, number of tillers, number of productive tillers, root fresh weight, root length, grain weight, and panicle length. The results indicated that varietal treatments had a statistically significant effect on all observed parameters, except for the number of leaves. The Sijior genotype exhibited the greatest plant height (58.22 cm), while the Meulaboh genotype recorded the highest values for the number of tillers (29.3), number of productive tillers (28.0), and root length (20.7 cm). The Kelik-3 genotype demonstrated the highest root fresh weight (173.3 g), whereas the Si Tappe genotype showed superior performance in grain weight (62.0 g) and panicle length (31.7 cm).Overall, comprehensive analysis of the data suggests that the Si Tappe, Beras Merah, Kelik-3, and Meulaboh genotypes exhibited the most favorable adaptive responses and demonstrated a high degree of tolerance to salinity stress. The robust root development observed in the Meulaboh and Kelik-3 genotypes supports their adaptability to saline environments, while the extended panicle length in Si Tappe positively contributed to enhanced grain weight.

Abstract

Refugia plants are able to control pest insects in cultivation plants, the benefits of refugia plants can become microhabibtat natural enemies. This research was conducted to see the diversity of natural enemy insects in the planting of shallots (allium cepa) by utilizing various flowering plants as edge plants. This research was conducted in the Teuku Umar University Experimental Garden. The research began in October-December 2023. This study used a non-factorial plot split plot design method with 5 levels and 4 treatments, namely: T0 = without refugia plants, T1 = Zinnia Elegans, T2 = Marigold Plants, T3 = Cosmos Plant, T4 = Zinnia elegans + marigold + cosmos. The results showed that insect identification there were 7 types of orders and 20 species of insect species. The result of the natural enemy diversity index value with the calculation of H 'data in all treatments is moderate. The results of the independence index of the type with the highest value are in the combination treatment reaching the E'1 value, which means according to E => 0.6 the level of compliance of the type is classified as high. In the yield of shallots for the highest lime weight, there is a combination of 1.890 kg.Keywords: Refugia, natural enemies, diversity, types of evenness
