Abstract

Coffee is one of the important plantation commodities that plays a significant role in the Indonesian economy. Gold Robusta coffee is a potential genotype currently being developed in Jember, particularly by the University of Jember, as an alternative to the common practice of using seedling cuttings with unidentified genetic origins. This study aimed to determine the optimal nitrogen (urea) dosage containing 46% N and its growth response on immature (TBM) Gold Robusta coffee plants. The research was conducted at the Experimental Field in Darsono Village, Arjasa District, Jember Regency, from May to December 2024. The experimental design used a Completely Randomized Design (CRD) with a single factor, consisting of three levels of urea fertilizer doses, namely 15 g, 30 g, and 45 g/plant, each replicated nine times. Observed variables included plant height, number of leaves, stem diameter, number and length of productive branches, leaf area, and chlorophyll content. Data were analyzed using ANOVA, and significant differences were further tested with Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that urea application significantly affected the growth of immature Gold Robusta coffee. A dose of 45 g/plant produced the best growth performance with an average plant height of 112.78 cm, 21.44 leaves, leaf area of 163.56 cm², and productive branch length of 47 cm. Therefore, urea application at 45 g/plant can be recommended as a fertilizer guideline during the immature phase of Gold Robusta coffee.

Abstract

The increasing demand for sugar is not accompanied by increased productivity of sugarcane, the primary raw material for making sugar. Utilizing dry land is one strategy to increase sugarcane productivity. Poor soil fertility caused by limited water and nutrients can affect the growth and productivity of sugarcane. It can be solved by using inorganic fertilizers combined with biological fertilizers such as Arbuscular Mycorrhiza in the planting media. One effort to increase the productivity of sugar cane plants is to improve the quality of sugarcane seedlings. The speed of growth at the beginning of the seeding period is determined by soil fertility and the variety of sugarcane plants used. This research was conducted from September to December 2023 at the Patrang Greenhouse, Jember Regency. This experiment was conducted using Factorial Completely Randomized Factorial Design (CRD) 2 factors with five replications. Factor 1 is the administration of mycorrhizal doses consisting of 4 levels, namely: Aₒ (0 grams), A₁ (5 grams), A₂ (10 grams), A₃ (15 grams). Factor 2 is the variety consisting of 2 types, namely, as follows: V₁ (Bulawang variety) and V₂ (PS 862 variety). The interaction of mycorrhizal dose treatment and the sugarcane variety significantly affected the plant's variable fresh weight. The combination treatment with a mycorrhizal dose of 15 grams applied to the PS 862 (A3V2) sugarcane variety gave the best results.
