Abstract

A study was carried out to determine the carbohydrate content of Spinach (Spinacia oleracea L.) which treated with only micronutrients (1ppm) stock solution and with different concentrations of humic acid. The experiment was done in four replications. Experimental treatment included seven micronutrients stock solution (1 ppm) which included CaCl2, CuSO4, MgSO4, MnSO4, ZnSO4, H3BO3 and FeSO4. Foliar application was done with micronutrients stock (1 ppm) only, micronutrients stock with different concentrations of HA (100, 1000, 10000 ppm). Soluble carbohydrate was determined by Anthrone method Spectrophotometry at wavelength of 750 nm. It was found that Spinach leaves treated with 1 ppm micronutrients stock mixed in 1000 ppm HA showed the highest percentage of carbohydrate followed by 1 ppm micronutrients stock mixed in 10000 ppm HA while control had the least. The findings of the investigation revealed that varying levels of carbohydrate content in the Spinach with different treatments analyzed which have direct comportment on their nutritional status.
