Microgreen Quality of Broccoli Plants (Brassica oleracea L.) and Correlation between Parameters

Abstract

Micro greens are vegetables harvested at a very early age, harvesting is done when cotyledon leaves and a pair of new leaves appear. Plant growth phases include germination, micro greens, baby greens, and mature in greens. This research aimed to determine the quality of microgreens broccoli (Brassica oleracea L.) that are water content, total chlorophyll, and dietary fiber due to the influence of planting media and coconut water nutrition. Broccoli microgreens are planted at the Green House of the Faculty of Agriculture, UPN "Veteran" East Java in November-December 2018. Analysis of water content using drying method(thermogravimetri), chlorophyll analysis using spectrophotometry method, and analysis of fiber content with Enzymatic-Gravimetric method. The data were analyzed using Completely Randomized Design (CRD) with the post hoc test LSD 5% and HSD 5% and correlation regression between parameters. The results of the study showed an increase in the quality of parameters and there was a close correlation between parameters. Correlation value of water content and total chlorophyll (r = 0.81) with a regression equation y = 1.907 ×-143.2, water content and fiber content (r = 0.84) with regression equation y = 2.628 ×-235.3 and total chlorophyll and fiber content (r = 0.88) with the regression equation y = 1.178 ×-32.05.
