Pengaruh Pemberian Pupuk Kandang Sapi dan Cacing Tanah terhadap Pertumbuhan dan Hasil Tanaman Kedelai (Glycine max (L.) Merril)

Abstract

Soybean (Glycine max (L.) Merril) is one type of food that have a high  nutrition, so many are consumed by the people. The needs of soybean in Indonesia each year has increased, while production of soybean in Indonesia is not enought to cover the needs of soybean in Indonesia. The study aim to know the influence of cow manure and earthworms as well as getting the best dose against and crop yield of soybean. This study was carried out the greenhouse of Unit Pelayanan Teknis (UPT), Faculty of Agriculture University of Riau. This study used a random complete design 2 factor and 3 replicates. The first factor is 4 dose of cow manure and the second factor is 2 level of earthworms. Result showed the cow manure 80 g/plant and earthworm 5 tail/plants shows better results among other treatment combination in increasing the ratio of headers and roots, dry weight of the plant, number of primary  branches, number of pods perplant and the weight of the seed per plant. Cow manure 80 g/plant best in increasing the shoot and root ratio, diameter of stem, number of primary  branches, number of pods per plant and the weight of the seed per plant. The weight of 100 seeds showed better on cow manure 40 g/plant and on a combination of cow manure 40 g/plant and earthworm 5 tail/plant. Use of earthworms did not improve growth and yield of soybean.
