Mitigation of Salinity Combined with Vermicompost on Growth, Antioxidant Enzymes and Macro Nutritional Changes in Solanum melongena L.

Abstract

Background: The main abiotic stress affecting crop production and productivity is due to the salinity stress, which has a very serious adverse effectiveness on plant development and production. At higher concentrations, salt stress provokes the accumulation of reactive oxygen species ROS, which are toxic to cells. Methods: The goal of the current study was to determine how different sodium chloride (NaCl) concentrations affected Solanum melongena growth, antioxidant enzymes and macronutrients through the use of vermicompost. Vermicompost (VC) (%) (0, 10, 25, 50, 10 mM+5%, 25 mM+10%, 50 mM+25% and 100% VC) was used in the germination investigation and the data were evaluated 30- and 60-days following germination. Result: In 50 mM of NaCl plus 25% VC, the greatest increases in the length of the shoot, length of roots, both dry and fresh weight and leaf area were noted. On both days, the maximum enzyme activity was observed at 50 mM NaCl + 25% VC. The use of vermicompost in NaCl stress enhanced the nutritional contents up to 50 mM + 25% VC, while the accumulation of macronutrient content increased at an extreme level of 100% VC.
