TYPES OF NUTRIENTS AND INFLUENCES ON THE PRODUCTIVITY OF WATER SPINACH IN HYDROPONICS

Abstract

Nowadays, hydroponic models have been widely applied in Vietnamese cultivation. Hydroponics is a very modern method that promises to make a lot of valuable contributions to the agriculture of Vietnam. The project of this modern method was conducted in October – December 2018, aimed to acknowledge the influences of different nutrient hydroponic solutions on the survival and the growth of water spinach (Ipomoea aquatic) planted by the hydroponic method. The experimental models are commenced with 3 formulas and 3 repeating times for the data of water (including pH and TDS) as well as the nutrient solutions in order to determine effects on the efficiency of cultivated vegetables (specifically on the speed of breeding leaf, growing root, and the harvesting productivity). Through the analysis below, it is possible to comprehend that the third nutrient formula is the most effective one in height growth, productivity, and the speed of breeding leaf.
