Abstract

One of the much-needed agricultural commodities in Indonesia is soybeans after maize and rice, both as a humanfood, animal feed and industrial raw materials. However, in the development of soybean plants some issues related toagro-ecosystem for planting must be overcome, one of which is not optimal weed management. Competition betweencrops 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 suppressweed growth and yield of soybean plants. Under these conditions, the specific target of this research is to get a dose oforganic mulch reeds effective in suppressing weeds in soybean. In addition, to obtain soybean plants were healthy andfree of synthetic herbicides towards organic farming. The results of this study are expected to provide information tofarmers in the use of organic waste can be used as a ground cover or mulch to suppress weeds in soybean plants. Underthese conditions, the specific target of this research is to get a dose of organic mulch reeds effective in suppressing weedsin 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 aground cover or mulch to suppress weeds in soybean plants.

Abstract

One way to improve the productivity of soybean grown as an intercropping plant in the standing area is to develop soybean varieties that are tolerant to shade. This experiment aimed to discover the physiological characteristics in soybean varieties that are tolerant to shade.The results showed that the significant physiological characteristics that determine the level of the soybean tolerance to shade are nitrogen and protein contents.The increasing of nitrogen and protein contents was higher in the tolerant varieties than those of sensitive varieties. Shade treatments affected seed weight. The soybean yield on the 50% shade decreased by 23.11% in the tolerant varieties, and about 27.63% decreased in the sensitive varieties. The yield decrease was lower in tolerant varieties compared to the sensitive varieties. This result was supported by the lower reduction in empty pods.Mechanism of tolerance to shade on soybean plant is characterized by the increase of nitrogen and protein contents. In addition, higher yields on tolerant varieties supported by high pods contain and low empty pods.Key words: Soybean, nitrogen and protein contents.
