Utilization azolla liquid organic fertilizer with goat manure to enhance organic okra (Abelmoschus esculentus L. Moench) production

Abstract

Azolla is found abundantly in rice fields in Indonesia, therefor potentially as a source of biological nitrogen derived from natural biological bodies that are renewable. The use of a combination liquid fertilizer from fermented azolla with goat manure which is used as a source of nutrients and to improve soil quality as an effort in developing and implementing sustainable agriculture in cultivation of okra plants, needs to be studied. Okra is a vegetable that has many benefits for health which can be consumed in fresh or processed form. This research was carried out on Faculty of Agriculture, Universitas Sumatera Utara, Medan, from August to December 2022, using a randomsized block design with two factors, the first factor is azolla liquid organic fertilizer (75, 150, 225, and 300 ml/polybag) and the second factor is goat manure (0, 100, and 200 g/polybag). The application of 200 g/polybag goat manure with150 ml/polybag azolla liquid organic fertilizer or 100 g/polybag goat manure application with 300 ml / polybag azolla liquid organic fertilizer in okra plants can substitute the use of inorganic fertilizer for increased yield and environmental preservation.
