Nutrient Release Pattern and Greenhouse-Grown Swiss Chard Response to Biochar Inoculated with Vermicast

Figure 4

Plant height (PH), stem diameter (SD), leaf area (LA), and total edible leaf fresh weight (LFW) of Swiss chard (Beta vulgaris subsp. vulgaris) cv. Rhubarb chard as affected by biochar alone (Bioc), deionized water-inoculated biochar (DWB), solid vermicast-inoculated biochar (SVB), vermicast tea-inoculated biochar (VTB), and Promix-BX alone (Pro-BX). Lowercase and uppercase alphabetical letters represent mean separation by the least significant difference (α = 0.05) at the first (1) and the second (2) harvests, respectively. Vertical lines on bars represent standard error of the means.
