Protective Cultivation System (PCS) is a way of protecting crops from harsh external conditions, pests, and diseases. Greenhouses, tunnels, or shade nets create an enclosed space where factors like temperature, humidity, and light are monitored and controlled. This conserves water, reduces pesticide use, and allows cultivation of crops year-round. PCS also increases yields and quality of crops, and profits for farmers. It’s used worldwide and is sustainable, and produces high-quality fruits, vegetables, and flowers. PCS is an efficient method of producing food on a large scale, ensuring yield stability, and enhancing shelf life of crops.
