TEKNIK MULSA VERTIKAL PADA BUDIDAYA TEBU (Saccharum officinarum.L) RATOON SATU
Abstract: Sugarcane (Saccharum
officinarum.L) is the main material in sugar industry. An effort to improve the
quality of dry land for sugarcane cultivation is important. One of the effort
than can be done is the additional of organic metter to the soil. The objective
of this research was to determine the effect of vertical mulching techniques
for soil organic matter content and soil chemistry fertility and its
relationship with the vegetative growth of the ratoon sugarcane. This research
was conducted at Agricultural High School Practice (STPP) Medan-Binjai KM.10
districts Sunggal Deli Serdang, North Sumatra, from May -December 2013. This
study was conducted using a randomized block design non factorial with four
treatments, were: horizontal mulch (M1), vertical mulch (M2), vertical mulch
with Trichoderma sp. (M3), Vertical mulch mixed with cow manure (M4). The
result from the research showed, that vertical mulch mixture with manure can
increase the level of C-organic, N-content, and the lower of Ratio C/ N .
Vertical mulching treatment mix with manure, increasing the shoot length of
sugarcane 21.9%, the number of plants per clump 6.8%, the number of plants per
meter 50%, wet weight 68.28% and dry weight 41.9%, compared with horizontal
mulch.
