Improving Soil Fertilizer Through Application of Organic Fertilizer Humid Acid and Mikoriza in Supporting Growth and Production of Chilli Plants In Sand Land

Abstract

Availability of agricultural land has decreased, especially fertile rice fields and potential with technical irrigation caused by the use of land into non-agricultural land. Therefore, it is necessary to expand the area of agriculture by utilizing marginal land such as sand land. The purpose of this study is to get the best treatment combination of organic fertilizer, humic acid and mycorrhiza to support the growth and production of chili on sand land. This research activity was carried out in May to November 2018 in the greenhouse, Plant laboratory of the State Polytechnic of Jember, East Java at an altitude of 90 m above sea level. The research design used in this study was a non factorial complete randomized block design with twelve treatment combinations of doses from organic fertilizer, humic acid and mycorrhizae with three replications. Data from observations were analyzed by variance analysis with SAS version 9.0 software. If there is a real effect from treatment, the results are further tested using Duncan multiple range test at the level of 5%. The experimental results show that application of combination of organic fertilizer + humic acid + mycorrhizae can increase plant growth at 14 days to 35 days after planting. The best growth results of the best plants were found in organic fertilizer at a dose of 20 tons / ha + humic acid with a concentration of 200 ppm + mycorrhizae with a dose of 30 g/plant.
