Abstract


Peanut is one of the source of protein for human foods. Production of peanuts
can be increase by land cultivation and giving vermicompost. This research aimed to
evaluate the effect of land cultivation and giving vermicompost for growth and
production of peanuts. The study was conducted in Tanjung Sari, Kecamatan Medan
Selayang. This research used split plot design, with two factors. First factor is land
cultivation with 4 levels (traditional tillage with two stage of cultivation, traditional
tillage with one stage of cultivation, minimum tillage, and no-tillage).The second
factor is the ratio of vermicompost and chemical fertilizers, whith 5 levels
(chemical 100%,vermicompost 100%, vermicompost 75% + chemical fertilizer
25%, vermicompost 50% + chemical fertilizer 50%, and vermicompost 25% +
chemical fertilizer 75%. The result showed that land cultivation significantly
affected the parameters the number of ginofor 2 and 3 month after planting
(MAP), the number of filled pod, 100 seed weigth, production per sample and
production per plot. The ratio of vermicompost and chemical fertilizers
significantly affected the parameters of the number of branch 1 and 2 MAP. The
interaction between land cultivation and the ratio of vermicompost and chemical
fertilizers did not significantly affected for all parameters.
Keywords : land cultivation, vermicompost, peanuts.
