Abstract

This research aims to study the effect of shade on morphophysiology character and results of soybean Petek andJayawijaya varieties. The study was conducted at the experimental site of Faculty of Agriculture, University of Jambi.Materials and tools used are paranet 50%, soybean seed Petek variety (shade tolerant) and Jayawijaya variety (shadesensitive), manure, NPK fertilizer, fungicide and insecticide. Equipment used includes field equipment, clear nail polish,microscope camera, analytical scales, tweezers and others. This study used a split plot design consisting 2 factors. Thefirst factor is the shade as the main plot (N) which consists of two levels, namely the auspices of 0 % (no shade) and 50% of shade. The second factor (subplot) is soybean varieties are Petek variety and Jayawijaya variety. The resultsshowed that the Petek showed consistency as shade-tolerant variety in shade 50% to show the state of the leaves arethinner, wider leaves, a decrease in stomatal density is lower and higher chlorophyll content compared with Jayawijayavariety (shade sensitive). There is no interaction between treatment shade and variety.

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. In this experiment to test the effectiveness of various dosesof 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 (plantheight, shoot dry weight, number of pods containing, weight of 100 seeds, and soybean crops). The experiment wasconducted by using a randomized block design. Through this study it was found that the dose of mulch reeds that can beapplied as a soil cover (mulch) on soybean planting is at a dosage of 15 tons ha -1 (D3) and 20 tons ha -1 (D4).
