Abstract
Effect of weed control on yield of Ubi Alabioat medium deep swampland in South
Kalimantan. The aim of the experiment wa's to study the effect of weed control methods
on yield of ubi Alabio (Dioscorea alata L), conducted at Babirik, Hulu Sungai Selatan on
the dry season 1994. The treatments consisted of nine weed control methods i,e; (a)
weeding 1x at 30 days after planted, (b) weeding 2x at 30 and 60 days after planted, (c)
mulch 2 tlha, (d) herbicide Piperophos 2,4-0 IPE, (e) herbicide Metolachlor, (f) herbicide
Piperophos 2,4-0 IPE + weeding 1x at 30 days after planted, (g) herbicide Piperophos
2,4-0 IPE + mulch 2 tlha, (h) herbicide Metolachlor+weeding 1x at30 days after planted,
and U) herbicide Metolachlor + mulch 2,5 tlha + weeding 1x at 30 days after planted,
The experiment arranged in RCBO with three replications. The results of the experiment
showed that weed control methods, was not significantly effect tuber yield, but
signicifant to percentage weed cloths grade and weed dry weight. The highest yield
obtained by treatment of herbicide Piperophos 2,4-0 IPE + mulch 2 tlha at 3,93 kg/stick
and the lowest yield by the treatment weeding 1x at 30 days after planted at 2,77 kg/stick,
The highest weed dry weight by the treatment controled of mulch 2 tlha at 16,42 g/0,5
m2, and the lowest weed dry weight by the treatment controled of herbicide Metolachlor
+ mulch 2,5 tlha + weeding 1x at 30 days after planted at 7,52 g/0,5 m2,
