Pengaruh Aplikasi Compost Tea Berbahan Dasar Kipahit (Tithonia Diversifolia) Terhadap Pertumbuhan dan Hasil Tanaman Pakcoy (Brassica Rapa L.)

Abstract

Pakcoy is a leaf vegetable that needs fertilizer with a high N content. A fertilizer that can be used to meet the needs of plant nutrients, especially nitrogen, is compost tea fertilizer made from Tithonia diversifolia. This study aims to determine the increase in pakcoy productivity by applying Tithonia diversivolia compost tea fertilizer. This research was conducted in Randuagung Village, Sumber Jambe District, Jember Regency September 20, 2022 - December 26, 2022. Complete Randomized Block Design factorial two factors with three replications. The first factor is three levels of compost tea fertilizer formula based on the ratio of compost: water, namely J1 (1:1), J2 (1:5) and J3 (1:10). The second factor is four levels of compost tea concentration, namely N0 (control), N1 (100 ml), N2 (200 ml) and N3 (300 ml). The results showed an interaction effect of the combination of compost tea formula treatment and concentration on the growth and yield of pakcoy plants. The interaction effect plant height, chlorophyll content, root volume, plant fresh weight and leaf moisture content. The effect of a single factor on the variable number of leaves, leaf area, and dry weight of plants that are influenced by both factors. The best treatment combination that increases the growth and yield of pakcoy plants is the compost tea formula with a ratio of 1 kg of compost: 1 liter of water and a concentration of 100 ml / plant.
