Pengaruh Hidrogen Sianamida terhadap Pertumbuhan dan Produksi Tanaman Teh (Camellia sinensis (L.) O. Kuntze) setelah Pemangkasan

Abstract

The experiment was aimed to study the effect of hydrogen cynamide on tea growth andproduction after pruning. The experiment was conducted at Goalpara Tea Plantation (1 100 m above sea 1evels)from September 1994 to March 1995. Clone TRI 2025 planted in 1976 with 29 months pruning cycle was pruned a week before application of' hydrogen cynamide. Randomized Complete Block Design was used in this experiment with four treatmeants and.four replications. Treatments consist of hydrogen cynamide O.QO % (control), 0.50 %, 1.25 % and 2.50 %. An experiment unit consists of 20 tea plants. The results showed that treatments of hydrogen cynamide was not signiJicant1y increase the number of' shoots and weight of "tipping" (shoot tipped on $rst plucking). The production was not significantly increased by the treatments. However, hydrogen cynamide at 0.50 % could increase 11.5 % fresh weigh! (equivulent of 9.9 % dry weight).
