Abstract

Background: Robusta (Coffea canephora) is one type of coffee widely cultivated in Indonesia and is one of the leading commodities. Coffee seeds include seeds that have a long dormancy period that inhibits the germination process. Breaking dormancy can be done by several methods, one of which is soaking in natural growth regulators. Soaking treatment with natural growth regulators can be combined with soaking time treatment to break dormancy. This study aimed to determine the combination of natural growth regulator treatment and the right soaking time for Robusta coffee seed germination. Methods: This research is a 3-repeat Complete Factorial Randomized Design Experiment with the first factor of natural growth regulators type, which consists of 4 levels, namely: Z0 = control; Z1 = coconut water; Z2 = onion extract and Z3 = bamboo shoots, and the second factor is the length of soaking which consists of 3 levels, namely P1 = 12 hours; P2 = 24 hours and P3 = 36 hours. Results: Natural growth regulators' treatment of shallot extract with 24 hours of soaking time gave the best results on all parameters. Conclusions: Using natural growth regulators from coconut water, shallots, and bamboo shoots with several soaking times affects all parameters observed, both in single and combined administration.

Abstract

Background: The purple eggplant is a vegetable commodity that highly favored by many people due to it is delicious taste and benefical nutrition content for health. The demand of purple eggplants increased significantly every year, but it is often not matched by an increase in production caused by poor cultivation. The increased production can be achieved through several efforts, one of which is fertilization with organic materials. This research aims to determine the optimal combination and concentration of each treatment for the application of liquid organic fertilizer (LOF) and biological fertilizer which can provides the best influence on plant growth and yield of purple eggplant. Methods: This research used a completely randomized design (CRD) consisting of 2 factors. The first factor was the concentration of liquid organic fertilizer (N) divided into 3 levels, consists of 0 ml/l (N0), 4 ml/l (N1), and 8 ml/l (N2). The second factor was the concentration of bio-fertilizer (P) divided into 4 levels, consists of 0 ml/l (P0), 10 ml/l (P1), 20 ml/l (P2) and 30 ml/l (P3). Results: The result indicated that the concentration of 8 ml/l LOF and 30 ml/l bio-fertilizer was able to increase the number of leaves, total flowers per plant, total fruits per plant, and total fruits fresh weight per plant. Conclusions: This Research can be concluded that the concentration of 8 ml/l LOF and 30 ml/l bio-fertilizer gave the best effect on purple eggplants.
