Hanafiah DS, Sanggita S, Lubis K. 2018. The phenotypic appearance of Japanese persimmon (Diospyros kaki L.f.) in Karo District, North Sumatra, Indonesia. Biodiversitas 19: 509-514. The farmers in Karo District began to be less interested in cultivating kesemek or Japanese persimmon (Diospyros kaki L.f.). Due to the price of this commodity has dropped in the market, the farmers cut down the tree and cultivate more favorable horticultural crops, such as vegetable and citrus cultivation. It is necessary to conduct a study to obtained sufficient information to determine the necessary steps in order to preserve Japanese persimmon plants in Karo District. One first steps was to get information of accession characteristic of Japanese persimmon in Karo District. This research aimed to identify relationships of morphological characteristics among individuals of Japanese persimmon plants. The research was conducted from May until July 2017 at Berastagi, Merdeka, Kabanjahe, and Dolat Rayat sub-districts of Karo District, North Sumatra, Indonesia. The survey method using Japanese persimmon descriptor of Diospyros kaki L.f. by the International Union for the Protection of New Varieties (UPOV) with the purposive method for location determination and technique sampling. Thirty-six accessions of Japanese persimmon plants were studied. Based on clustering method of the morphological characteristic, 4 clusters are formed. This difference was canopy form, leaf shape and fruit morphological. Accession 34 from Dolat Rayat Distict has different fruit characters with other accessions.
The combination of Biotara bio fertilizer and dolomite is known to improve the potential acid sulphate soil fertility. This research has been carried out to examine the effect of Biotara as bio fertilizer, chicken manure, and dolomite on several soil chemical properties and soybean growth in potential acid sulphate soil from May 2018 to January 2019 at greenhouse of Agricultural Faculty, Universitas Sumatera Utara Medan. This research has been carried out using factorial randomized block design with 2 (two) factors and 3 (three) replications and analysed using ANOVA. The first factor is biofertilizer consist such as P0 (without biofertilizer), P1 (50 kg/Ha), P2 (50 kg/Ha with 1 ton/Ha of chicken manure). The second factor is the consist of dolomite, such as K0 (without dolomite), K1 (2 ton/Ha), and K2 (4 ton/Ha). The results showed that the combination of biofertilizer (50 kg/Ha) with chicken manure (1 ton/Ha) can increase pH, organic carbon, total-N, and available phosphate, height and dry weight of crop, N and P uptake of soybean. Interaction between biofertilizer (50 kg/Ha), chicken manure (1 ton/Ha) and dolomite (4 ton/Ha) showed the best yield on total-N and available phosphate, height, and dry weight, N and P uptake of soybean.
