USE OF SALT INDUSTRIES BYPRODUCT AS AN ALTERNATIVE LIQUID FERTILIZER IN FLOATING HYDROPONIC LETTUCE IN BANGLADESH
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
Salt industries byproduct is a less expensive fertilizer source. But without testing its effect on growth and yield, it may not be suitable as fertilizer. Therefore, a laboratory trial was conducted to evaluate vegetative growth, physiological growth traits and yield of lettuce cv. ‘Lolorossa’ by application of three salt industries byproduct concentrations at 0 (T1), 0.5mL.L-1 (T2) and 0.75 mL. L-1(T3) into ¾ strength Rahman and Inden (2012) nutrient solution. Plant height, number of leaf, leaf length, fresh weight, and physiological growth traits, viz., leaf area (LA), leaf mass ratio (LMR), leaf area ratio (LAR), root weight ratio (RWR),net assimilation rate (NAR) and relative growth rate (RGR) were observed. Results revealed that the maximum number of leaf, leaf breadth and fresh weight were found in salt industries byproduct at 0.5 mL•L-1 compared to the control. But the vegetative growth was negatively affected by the application of salt industries byproduct at 0.75mL•L-1. Physiological growth straits were negatively affected with increasing rates of salt industries byproduct. It was further found that RGR, NAR, and their related components improved when 0.5 mL•L-1 salt industries byproduct was applied compared to the control in lettuce. It may be concluded that salt industries byproduct can be used as liquid fertilizer source in hydroponic lettuce culture.
