“…Liquid organic fertilizer has some benefits, among them being able to reduce the chemical fertilizers using [16]. Liquid organic fertilizer can increase the growth and yields of tomato [17,18], mustard [19,20] leek [21], soybean [22], and sweetcorn [23]. Giving liquid organic fertilizer from the raw materials of kirinyu and manure of rabbits can produce the growth and yields of cabbage high [24].…”

Shallots are a vegetable commodity that is considered used as a spice in cooking, so the need of the consumer is high. To supply this high consumption is needed increased productivity. Productivity can be increased by using varieties suitable for the growing environment, quality seeds, and proper fertilization. One of the uses of quality seeds is from seeds, but to obtain high production from seeds, appropriate fertilization is necessary. The goal of the study is to establish the liquid organic fertilizers type and the shallot variety from true shallot seed (TSS) can increase yield in the highlands. This research was conducted in IP2TP Berastagi, with a height of 1340 m asl and andisol. This study was conducted from May to September 2018. The Randomized Block Design factorial was used as a research design with 3 replications. The first factor is liquid organic fertilizer (LOF): Without LOF, Rabbit manure LOF, Fish fertilizer LOF, and Fish LOF. The second factor is shallot varieties from seed: Bima, Trisula, and Tuktuk. The results showed that the growth of shallots had no effect in giving liquid organic fertilizer to the seeds. The Trisula shallot variety can adapt to grow and produce well in highlands, while the Tuk-tuk variety is only adapted for growth and the Bima variety is less adaptive for growth and yield. The Trisula shallot variety with rabbit manure liquid organic fertilizer was able to give the best results compared to other treatment combinations (increased the yield by 13.70 – 65.10%.). The Trisula variety can be recommended for planting in highlands by utilizing LOF of rabbit manure.

Forest clove (Syzygium obtusifolium L.) has not been widely known for its properties and characteristics. To recognize them properly, deeply, and thoroughly, efforts are required to characterize the morphological characteristics of the main organs. The research aims to reveal the morphological characteristics of the main organ (cormus) of the forest clove plant, which include roots, stems, and leaves. The research was conducted on the island of Ambon, Maluku, Eastern Indonesia, for five months from May-September 2020. This research is survey research, data collection using a questionnaire arranged according to IPGRI criteria. The list of questions was filled indirectly to the field. The results showed that the root system of the forest clove plant was a taproot consisting of primary roots followed by lateral roots (primary root branches), secondary, tertiary, and quartet-like roots which were then overgrown with root hairs. Lateral root branches are large, and in subsequent root branches, the size is smaller but in increasing numbers. The trunk is round, with a diameter ranging from 12.5-25.5 cm, the surface of the trunk is rough brown and grayish, accompanied by black spots. The branching pattern is intensive with the main branching angles included in the medium category, meaning that the angles formed with the main rods range from 45-90o. The leaves of the forest clove plant are oblong with a length ranging from 15-25.5 cm and a width of 5.5-9.5 cm. The correction factor to determine leaf area is 0.65, therefore the leaf area ranges from 53.63 to 157.46 cm2. The shape of the base of the leaf is tapered, the angle of the petiole is sharp (<45o). The nature of the tips of the leaves is rather hard, the texture of the leaves is strong, the edges are flat, and the color of the leaves is dark green (green 139 A).
