The aim of the research was to identify the effect of GA3 concentration and soaking period on the seed yield of shallot. Research was conducted at Hatoguan Village, Palipi Subdistrict, Samosir from February up to July 2014, carried out by using randomizes block design with two factors, replicated three times. The first factor was GA3 concentrations (50 ppm; 100 ppm; 150 ppm; 200 ppm; and 250 ppm) and the second was soaking period (30; 60; and 90 minutes). Parameters observed were the number of plant producing flowers per plot, the number of umbel per plot, seed weight per umbel, and seed weight per plot. The results showed that among all parameters observed, only the number of plants producing flowers per plot and seed weight per umbel were affected by GA3 concentration. The highest number of plants producing flowers and seed weight per umbel were produced by G4 (200 ppm GA3) i.e 10,780 plants (43,12 %) and 0,202 g respectively. Meanwhile, only seed weight per umbel was significantly affected by soaking period. The correlation between soaking period and seed weight per unbel showed positive linear regression.Key word: GA3 consentration, soaking period, shallot

The purpose of the research was to determine the influence of coconut water concentration and duration storage of rootstock to the percentage of budding success and cassava’s (mukibat) growth. The research was conducted at the screen house of Agriculture Faculty USU (± 32m asl) in March-June 2017 using Factorial Randomized Block Design (RAK) repeated 3 (three) times. The first factor was the coconut water concentration with 4 (four) levels ie without coconut water, 25% coconut water, 50% coconut water and 75% coconut water and second factor of storage duration of rootstock with 3 (three) treatment levels: 1 (one) week storage, 2 (two) weeks storage, and 3 (three) weeks storage. Parameter observed were percentage of budding success, spinning rate, shoot height, shoot diameter, number of leaves, number of tubers, root wet weight, and root dry weight. The results showed that the coconut water concentration had a significant effect on the success rate of budding, root wet weight, and root dry weight. Where the best coconut water concentration is at 50% coconut water treatment. The longer duration storage of rootstock gives fewer percentage of budding success. The best storage time for rootstock was 1 (one) week storage. The interaction of coconut water concentration and storage duration of rootstock had significant effect on the number of leaves.
