Abstract

Mining may directly affect the surrounding environment if the tailings produced were not processed properly. Tailings from gold mining activities caused critical land condition both physically and chemically. The damage of environment caused by mining activities need to rehabilitated. Rehabilitation can be done through revegetation of pioneer plants, addition of organic matter, and potential microbiological applications. This research was conducted to determine the potential of organic matter and Azotobacte inoculant for gold mine tailing rehabilitation on soil total N, N uptake, and growth of peanut. Experiment was carried out at Biology Laboratory, Soil Fertility and Plant Nutrition Laboratory Department of Soil Science and Land Resources and Greenhouse of Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. The experimental design was Split Plot consisted of three replications. Main plot is dosages of organic matter consisted of 1,5%, 3% and 4,5% dosages, sub plot was the species of Azotobacter and consisted of control, indigenous Azotobacter sp., Azotobacter chroococcum, indigenous Azotobacter sp. and Azotobacter chroococcum constria. The result showed there was no interaction between Azotobacter sp. inoculant and organic matter toward total N, N uptake, and growth of peanut on tailing. Organic matter of 1,5% and 3% significantly increased total N of soil.Keywords: Azotobacter, nitrogen, peanut, tailing

Abstract

This study was aimed at determining the increasing of growth and production of soybean crops by giving Azotobacter sp. and additive materials such as coconut water, molasses, and bran. This research was conducted on Januari 2018 to April 2018 at Ciparanje Experimental Field Faculty of Agriculture. Universitas Padjadjaran, Jatinangor, Sumedang, West Java Province, on ± 774 meters above sea level (asl) using single factor randomized block design with 10 treatments; Azotobacter sp. and additive materials combination such as coconut water, molasses, and bran in three repetitions. The observations on the parameters observed in the final vegetative phase were on plant height, chlorophyll content, and population of Azotobacter sp. using Total Plate Count (TPC) method.The results show that the application of combination additives materials and Azotobacter sp. effect on populations Azotobacter sp., chlorophyll content, plant height and number of soybean pods (Glycine max L.). Application of coconut water independently, water added with Azotobacter sp., and combination of additive with Azotobacter sp. can give the best effect to the content of chlorophyll, plant height, and soybean crops components (Glycine max. L.).PENGARUH KOMBINASI BAHAN ADITIF DAN Azotobacter sp. TERHADAP PERTUMBUHAN Glycine max. L.Penelitian ini bertujuan untuk mengetahui pertumbuhan dan produksi tanaman kedelai dengan memberikan Azotobacter sp. dan aditif air kelapa, molase, serta dedak. Penelitian ini dilaksanakan pada Januari 2018-April 2018 di Kebun Percobaan Ciparanje Fakultas Pertanian Universitas Padjadjaran, Jawa Barat pada ± 774 meter di atas permukaan laut (dpl). Penelitian ini menggunakan rancangan acak kelompok dengan 10 perlakuan pemberian Azotobacter sp. dan aditif air kelapa, molase, serta dedak dengan tiga ulangan. Pengamatan terhadap parameter yang diamati pada fase vegetatif akhir yaitu tinggi tanaman, kandungan klorofil, dan populasi Azotobacter sp. dengan metode Total Plate Count (TPC). Hasil penelitian menunjukkan aplikasi kombinasi bahan aditif dan penambahan pupuk hayati Azotobacter sp. berpengaruh terhadap populasi Azotobacter sp., kadar klorofil, tinggi tanaman dan jumlah polong tanaman kedelai (Glycine max L.). Aplikasi air kelapa secara mandiri, air kelapa yang ditambahkan dengan Azotobacter sp., dan kombinasi bahan aditif dengan Azotobacter sp. dapat memberikan pengaruh terbaik terhadap kandungan klorofil, tinggi tanaman, dan komponen hasil tanaman kedelai (Glycine max. L.).
