Pemberian Mulsa Alang-Alang (Imperata Cylindrica) untuk menekan gulma pada Pertumbuhan dan Hasil Tanaman Kedelai (Glycine max L. Merill)

Abstract

One of the much-needed agricultural commodities in Indonesia is soybeans after maize and rice, both as a human
food, animal feed and industrial raw materials. However, in the development of soybean plants some issues related to
agro-ecosystem for planting must be overcome, one of which is not optimal weed management. Competition between
crops and weeds can be overcome one of which is to provide soil cover (mulch) that can suppress the growth of weeds.
The purpose of this research is to test the effectiveness of multiple doses of organic mulch reeds to its ability to suppress
weed growth and yield of soybean plants. Under these conditions, the specific target of this research is to get a dose of
organic mulch reeds effective in suppressing weeds in soybean. In addition, to obtain soybean plants were healthy and
free of synthetic herbicides towards organic farming. The results of this study are expected to provide information to
farmers in the use of organic waste can be used as a ground cover or mulch to suppress weeds in soybean plants. Under
these conditions, the specific target of this research is to get a dose of organic mulch reeds effective in suppressing weeds
in soybean. In addition, to obtain soybean plants were healthy and free of synthetic herbicides towards organic farming.
The results of this study are expected to provide information to farmers in the use of organic waste can be used as a
ground cover or mulch to suppress weeds in soybean plants. In this experiment to test the effectiveness of various doses
of Reed mulch to suppress weed growth. Besides, community coefficient test, analysis of vegetation (SDR value of early,

middle and SDR SDR end), weight broadleaf weeds, narrow leaves and type of puzzle-tekian. Plant growth (plant
height, shoot dry weight, number of pods containing, weight of 100 seeds, and soybean crops). The experiment was
conducted by using a randomized block design. Through this study it was found that the dose of mulch reeds that can be
applied as a soil cover (mulch) on soybean planting is at a dosage of 15 tons ha -1 (D3) and 20 tons ha -1 (D4).
