The Foliar Spray Application of Selected Organic Fertilizers and Their Effects on Selected Plants

Abstract

Fertilizers are any organic or inorganic natural or synthetic materials [other than liming materials], which is applied to a soil to provide one or more plant nutrients necessary for plant growth. One of the most extreme conditions that have a detrimental impact on the climate is sandy soil. The use of different organic amendments is a tool for developing sustainable development that is both economically and environmentally viable. The aim of this study is to see how milk tea waste extract, banana peel extract and coconut peat extract affect the growth of coriander and spinach plants when applied as a foliar spray. Different pots for various organic fertilizers were used. In this study we discussed how they affected plant growth and how they improved the biochemical properties of sandy soil. The different concentration (2g, 4g, 6g) of banana peel powder, milk tea waste powder and coconut peat were used in this study. The result showed that the highest plant height, root height, number of leaves and shoot height was found in 4g milk tea waste powder in both plants spinach and coriander compared to other fertilizers and control plant. This observation is suggested that the use of milk tea waste is feasible amendment strategy for improving the growth and soil fertility quality of sediments.
