Application of Organic Fertilizer Cow Dung and Biofertilizer in Shallots (Allium Acalonicum L.) in Lowland

Abstract

Lowland has the potential to be developed to plant shallots, given the importance of shallots in meeting the growing needs of the Indonesian people and supported by a high market share, therefore to increase the productivity of shallots in Lowland it is necessary to apply organic cow dung and biofertilizer. The purpose of this study was to determine the best organic cow dung and biofertilizer in increasing the productivity of shallots on land or in lowland. This research was conducted in Seri Tanjung Village, Tanjung Batu District, Ogan Ilir Regency, South Sumatra Province. The layout of the experiment was in polybags using a factorial randomized block design with 8 treatment combinations which were repeated 4 times. Factor 1 is organic cow dung fertilizer, namely 0, 7.5, 15, 22.5 tons/ha. Factor 2 is biofertilizer, namely without and biofertilizer. The highest production (dry weight of plant tubers) was achieved in the application of organic cow dung fertilizer of 15 tons/ha with bio fertilizers, which was 53.56 g/plant.

“…In addition to their high nutrient content, these solid organic fertilizers also have advantages in improving the chemical, physical, and biological properties of the soil [12], [13]According to the American Plant Food Control Officials (AAPFCO), organic fertilizer is defined as a material containing carbon and one or more essential nutrients besides hydrogen and oxygen necessary for plant growth [14], [15]Meanwhile, according to the USDA National Organic Program, organic fertilizers are all fertilizers that do not contain prohibited substances and are derived from natural materials such as plants or animals, and sewage sludge, excluding non-organic materials. According to the USEPA, organic fertilizer is manure or compost applied to plants as a source of nutrients [16], [17]Organic fertilizer is derived from dead plants, animal manure, and/or other organic waste that has undergone engineering processes, either in solid or liquid form, which can be enriched with mineral substances and/or beneficial microbes to enhance soil nutrient content and organic matter, as well as improve the physical, chemical, and biological properties of the soil (Minister of Agriculture Regulation No. 70/Permentan/SR.140/10/2011).Organic carbon (C-organic) is the main component of organic matter.…”
