Abstract

Coffee is one of the productive agro-industries in Indonesia, so care needs to be taken to use varieties and doses of fertilizers based on plant needs and environmental conditions. This study aimed to determine the clone, dose of urea, and the interaction between the clone and the dose for Robusta coffee plants in the mother planting stock farm. This study used a split-plot design with coffee clones as the main plot and doses of urea fertilizer as subplots. The study showed no significant difference between clones in the growth of robusta coffee plants, where clone BP 534 was the best clone for plant growth. In addition, based on the study's results, the best interaction was obtained where the best interaction for increasing the number of leaves was between clone BP 936 and a dose of 15 g.plant-1. The interaction between clones and the best dose for increasing the height and number of branches was between clone BP 936 and dose 20 g.plant-1, and the interaction between clones and the best dose for plant stem diameter was between clone BP 358 and a dose of 20 g.plant-1.

Abstract

Coffee seeds are an important planting material in coffee cultivation. Coffee germination is a complex process. One of the efforts to germinate coffee seeds is by soaking the seeds in water. The purpose of this study was to determine the effect of the length of time soaking seeds in water on the germination of coffee seeds, knowing the effect of the length of time soaking in rice washing water on the germination of coffee seeds, and knowing the interaction between soaking with water and soaking with rice washing water on coffee seed germination. This study used a factorial randomized block design (RBD) with two factors, and was repeated three times. The results showed that water immersion had no effect on coffee seed germination, rice water immersion for 6 hours had an effect on plant height at planting age of 4 WAP and 11 WAP, and there was an interaction between water immersion time and rice water immersion time at 12 WAP planting age. The best combination is 12 hours of water immersion + 12 hours of rice washing water on wet weight of shoot and dry weight of shoot.
