Growth Effect of the Different Ratios of Wood Vinegar on Brassica juncea

Abstract

Four (4) different ratios of wood vinegar namely; 1:5; 1:10; 1:20 and 1:30 mL WV to water ratio extracted from coconut shell was tested to determine their growth effect on Brassica juncea or mustard plant or locally known as mustasa. Parameters measured were leaf number, plant height, plant leaf width. Using randomized complete block design, experimental tests were conducted using Brassica juncea as test plants. The samples of 10 days old were allowed to flourish in a potted plant with day to day application of the wood vinegar solutions together with the negative control for a total of 30 days. Results revealed that the wood vinegar ratios applied have no significant effect on the growth of the mustard plant in terms of its leaf number, plant height and leaf width. This indicates that coconut shell wood vinegar at 1:5, 1:10, 1:20 and 1:30 are not applicable ratios for plant production, as that an increased wood vinegar application increases plant production and growth.
