Abstract

Broccoli (Brassica oleraceae) is one of the prospective agricultural products to be developed in Indonesia because it is a source of vitamin A, B complex, C, ascorbic acid, thiamin, riboflavin, calcium, iron and minerals essential for the fulfillment of human nutrition and contains sulforaphane which can prevent cancer, besides it helps digestion, neutralizes acid and does not contain cholesterol. The amount of vitamin content found in broccoli makes the demand for broccoli on the market has increased by 15-20% per year. However, the high demand is not balanced with adequate quality and quantity of production. One of the causes of decreasing the quality and quantity of broccoli production is the use of inorganic fertilizers continuously. Provision of inorganic fertilizers or chemical fertilizers for a long time can cause soil damage in physics, biology, and chemistry. Plant organic waste is the raw material for the fermentation process for soil microbes which is useful for increasing the quantity and quality of crop production and maintaining environmental sustainability. Organic waste that has undergone a fermentation process can be used by plants as liquid organic fertilizer and at the same time can be used by plants as a stimulant to grow. The aim of the study was to examine the relationship between the dose and concentration of fruit organic waste extract to growth and yield of broccoli. The study was carried out on the integrated land of the Faculty of Agriculture-Animal Husbandry of the University of Muhammadiyah Malang from February to May 2018. It is a factorial experiment arranged in a Randomized Block Design and repeated 4 times. The first factor is the concentration of fruit organic waste extract, namely K1: 50 cc /l ; K2: 100 cc /l; K3: 150 cc /l, the second factor is the dosage of fruit organic waste extract, namely: D1: 50 ml /plant; D2: 100 ml /plant. The parameters of observation included plant height, number of leaves, stem diameter, flower diameter, flower weight, wet weight, dry weight. Data were analyzed using Fishers test, then tested using BNJ test 5%. The results showed no interaction between the concentration and dosage of fruit organic waste extract on the growth and production of broccoli plants. There is a positive correlation between each observed variable. The best concentration of fruit organic waste extract is 100 cc/l. The best dose of fruit organic waste extract is 50 ml /plant
