Yield Results Evaluation of Local Coffee Clones Tanggamus – Lampung

Abstract

Superior varieties are one of the components that play an important role in increasing agricultural products. One of the efforts to increase the production of coffee plants, among others, is introducing several local coffee clones that can be used as options in the development of coffee cultivation. This study aimed to evaluate the yield of local coffee growing in Tanggamus Regency, Lampung compared to national superior varieties. The research was carried out at the farmer's coffee plantation, Way Harong Village, Air Naningan District, Tanggamus-Lampung -Indonesia, from January 2018 to October 2019. The method used was a demonstration plot with a randomized block design with four replications. The six local coffee clones evaluated were: Kuning, Kasio, Hijau, Komari, Randu Alas, and Sailing coffee compared to the national superior variety coffee, SA 237. The evaluation of local coffee yield was aimed at the character of the number of production branches per plant, number of coffee cherries per productive branch, number of coffee cherries per coffee bunch, weight per dry bean, and yield of dry beans per plant. Evaluation in the second year (2019) was done after the plants received technological improvements with fertilization. The results which were analyzed using the analysis of variance (ANOVA) with the mean BNT test at the 5% level showed that among the six local coffee clones studied had very significantly different characteristics. The local clone Komari had the highest yield close to the national superior coffee yield, SA 237, while Sailing had the lowest yield.
