Pengaruh Pengelolahan Tanah Dan Konsentrasi Roundup Dalam Menekan Pertumbuhan Rhizome Tanaman Teki (Eleocharis dulcis) Effect Soil Tillage And Round Up’s Concentration to Press Down the Growth of Teki’s Rhizome (Eleocharis dulcis)

Abstract

The experiment was carried out to determinated the effect of soil tillage and Roundup’s herbicide concentration to press down the growth of “teki’s rhizome”. This research was conducted from Agustus up to October 1996. This research applied Complitely Randomized Design with two factors comprising three repetitions. Faktor I was the duration of submersion, comprising with raised bed and without raised bed; and factor II was concentration of Roundup’s herbicide, comprising 0.6, 0.9, 1.2, and 1.5 I per 300 I. For the differential test of treatment, it was apllied Duncan test 5%. The main parameters that observed were: mounth, dry weight, mount of tuber, and tuber dry weight of rizhome. Even though, the complementary parameters were relatively growth rate, net assimilation rate, leaf weight ratio, root weight ratio, and tuber weight ratio. The soil tillage and Roundup herbicide concentration influenced to all parameter observation significantly
