Soilless Vegetable Cultivation: A State-Level Scientific and Technological Project
The soilless vegetable cultivation project, designated as KC.07.20, is led by Associate Professor Dr. Ho Huu An along with colleagues from the Vegetable and Fruit Department at Hanoi University of Agriculture. This project focuses on scientific and technological advancements in safe vegetable production.
After five years of research investment and utilizing appropriate technological equipment, the project has successfully produced high-yield, high-quality vegetables that meet all four safety food standards. The levels of nitrates in the vegetables remain below the allowable limits, and harmful microorganisms are absent.
The net house system is constructed on sturdy steel frames, covered with insect-proof nets, shielding the crops from adverse weather conditions that could affect their growth. This technological model is implemented at every stage from seed sowing to planting, using substrates and over ten micronutrient elements as liquid fertilizer delivered in a drip irrigation system.
The advantages of this technology include maximizing the yield potential and quality of the crops while limiting pests and diseases. It allows for flexible seasonal cultivation, particularly for off-season vegetables, thereby reducing risks. Additionally, it enables the utilization of non-arable land to produce high-quality yield products.
At Techmart Vietnam 2005, the project authors signed numerous technology transfer contracts with individuals and organizations, with a total value exceeding 10 billion VND.
