Abstract

It is important to characterize the traits of local cultivars both morphologically, physiologically, and genetically. Characterization is a process aimed at identifying important traits economically valuable and beneficial for agriculture or determining the relevant characteristics  varieties. The objective of this study was to determine the diversity of several local upland rice cultivars from East Aceh and identifying the morphological characteristics of these cultivars. The research was conducted over 4 months, from October to February 2023, at the experimental field of the Faculty of Agriculture, Samudra University, Langsa City, Aceh, with an elevation of approximately 10 meters above sea level and a soil pH of 5.9. The study used data from both qualitative and quantitative traits, which were tabulated and then analyzed for kinship relationships using IBM SPSS software with hierarchical clustering analysis using Euclidean distance. The results indicated that the testing of several local upland rice cultivars from East Aceh, based on morphological characterization, showed differences in the number of tillers, flower characteristics, panicles, and leaf traits. However, there were no differences plant height, number of productive tillers, leaf blade color, and 1000-grain weight when observing grain weight. Differences in growth and production characteristics were due to interactions between genetic and environmental factors, leading to variability in traits among the tested cultivars. Based on the morphological characteristics of the 10 local upland rice cultivars from East Aceh, the Ramos Gunung and Sibontot cultivars were found to be among the most promising for development due to their highest production yields compared to other cultivars.

Abstract

The surrounding plain of Lake Toba is well known as a shallot producing area in North Sumatra Province. Samosir variety is the mainstay variety of shallot farmers in this area. One of the efforts to increase the productivity of shallot variety Samosir is the application of fertilizer. The amount of N, P and K nutrients given to the Samosir variety shallot plants must be appropriate. This study aims to obtain the optimum dose of N, P and K fertilizers in the cultivation of shallot varieties Samosir planted in the rainy season in the plains around Lake Toba. This study consisted of 3 parallel experiments to determine the optimum N, P, K fertilization with a non-factorial randomized group design (RAK). P2O5 and K2O fertilizers were applied 100% in the N rate experiment, N and K2O fertilizers were applied 100% in the P rate experiment, and N and P2O5 fertilizers were applied 100% in the K rate experiment. Each experiment consisted of 5 levels, namely 0, 50, 100, 150, and 200% of the reference dose and each treatment was repeated 3 times so that there were 45 experimental plots. Parameters were: fresh weight of tubers and crowns at the end of the vegetative period, crown weight and wind-dried harvest tubers. The results obtained the optimum dose of N and P fertilizer recommendations are 154.22 kg N ha-1 and 126.62 kg P2O5 ha-1. For K fertilization does not give a quadratic response pattern so there is no optimum dose.
