Publisher : Universitas Sumatera Utara

This research was conducted to obtain dose of municipal waste compost and P fertilizer which can improve the growth and production of the soybean. The research was conducted at experimental field of Agricultural Faculty of Sumatera Utara University, Medan which about ± 25 metres above sea level, begun from April to July 2015 using factorial randomized block design with two factors, i.e: doses of municipal waste compost (0 g/plant, 15 g/plant, 30 g/plant, and 45 g/plant) and doses of P fertilizer (0 g/plant, 1.5, and 3 g/plant). Parameters observed were plant height, stem diameter, number of books per plant, number of pods per plant, number of pods per plant lists, number of seeds per plant, seeds per plant weight, weight 100 seeds, and production of seeds per plots. The results showed that application of municipal waste compost significantly affected stem diameter at 2, 4, 5 weeks after planting,production of seeds per plots. Application of P fertilizer significantly affected number of pods per plant lists, number of seeds per plant, and seeds per plant weight. Interaction between aplication of municipal waste compost and P fertilizer not significantly affected on all parameters of observation.

ABSTRACT This research has been conducted to obtain dose of NPKMg and the kind of mulchs which can improve the growth and production of the shallot. This research had been conducted at Simalingkar B Medan in June-September 2015 using factorial randomized block design with two factors, dose of NPKMg (no NPKMg, 2, 4. 6, and 8 g/shallot) and the kind of mulch (no mulch, black silver mulch, and straw of rice mulch). Parameter observed were plant length, number of leaves per clump, number of tillers per clump, diameter of the bulbs per sample, wet bulb weight per sample, dry bulb weight per sample, wet bulb weight per plot, and dry bulb weight per plot. The results showed that aplication of NPKMg manure significantly affected parameter plant length 6-7 MST, not significantly affected other parameters. Aplication of the kind of mulch significantly affected plant length 2-8 MST, number of leaves per clump 2-3 MST, number of tillers per clump 3 MST, wet bulb weight per plot, and dry bulb weight per plot yet not significantly affected other parameters. Interaction between aplication of NPKMg and the kind of mulch not significantly affected on all parameters of observation.

The objectives of this research was to study the growth of green deli water apple (Syzygium samarangense (Blume) Merr. & Perry on difference plant materials and IBA concentrations. This research was conducted at experimental field of Agriculture Faculty, University of North Sumatera, Medan on August until October 2015, using randomized block design with two factors, i.e cutting plant materials (branches with shoot and branches without shoot) and IBA concentration (0; 50; 100; and 150 ppm) with 3 replications. The result showed that the growth of green deli water apple with branches without shoot better than branches with shoot, the application of 100 ppm IBA concentration has given better effect than the other treatments for growth of green deli water apple and the best combination for growth of green deli water apple was branches without shoot and 100 ppm IBA concentration.

The aim of this research was to study the effects of growth regulators BAP concentration on the number of leaves, shoots, and roots by using in vitro method. The research was conducted at the Tissue Culture Laboratory, Department of Agriculture, Banggai District in August - October 2015, This study used a Randomized Complete Design with one factor and six level of treatments i.e, BAP (M1 = 0.1 ppm; M2 = 1.0 ppm; M3 = 0.2 ppm; M4 = 2.0 ppm; M5 = 0.3 ppm; M6 = 3.0 ppm). The results showed that BAP at various concentrations was significantly influenced on the number of leaves at 4-10 weeks after planting, and have no significant effect on the number of shoots and roots.
