In both some of the atmospheric parameters are controlled for better crop growth.
Grenhouse cultivation is protected cultivation. In temperate climates greenhouse cultivation is essential when temperatures are below freezing.
Greenhouses are among the protected cultivation with higher in use of technology and level of control or protection as compared with simple shades and plastic tunnels.
Thanks Dr Sarda K, Dr M K Meric and Dereje Ashebir B for answering the question. Greenhouse is also a protected cultivation..
green house may be partially or fully control structure but I think protected cultivation is fully control structure i.e light, RH, cooling and heating system should be there.
Greenhouse cultivation is a technique of protected cultivation but not necessary vice versa because any method of protecting the plants from external environment is considered protected cultivation such as low tunnels.

Greenhouse cultivation and protected cultivation are both methods used to create controlled environments for plant growth, but they differ in their scale, construction, and level of environmental control.
1. Greenhouse Cultivation:
- Greenhouse cultivation typically involves the use of permanent or semi-permanent structures made of glass, plastic, or other transparent materials.
- Greenhouses are designed to capture solar radiation to create a warm and humid environment suitable for plant growth.
- These structures often have a framework made of metal or wood, with walls and roofs constructed of glass or plastic panels.
- Greenhouses are equipped with environmental control systems such as heating, cooling, ventilation, and irrigation to maintain optimal growing conditions throughout the year.
- They are commonly used for growing a wide range of crops, including vegetables, fruits, flowers, and herbs, on a commercial scale.
- Greenhouse cultivation allows for year-round production, protection from adverse weather conditions, and precise management of light, temperature, humidity, and pests.
2. Protected Cultivation:
- Protected cultivation refers to a broader category of techniques used to shield plants from external environmental factors, such as wind, rain, temperature fluctuations, and pests.
- Unlike greenhouses, protected cultivation can include a variety of structures and methods, ranging from simple low tunnels and high tunnels to shade houses, row covers, and cloches.
- These structures may be temporary or semi-permanent and can be constructed using materials such as plastic film, shade cloth, or row cover fabric.
- Protected cultivation systems are often more cost-effective and flexible than traditional greenhouses, making them suitable for small-scale or seasonal production.
- While they may provide some level of environmental control, such as temperature moderation and pest exclusion, protected cultivation systems typically offer less precise control compared to greenhouses.
- Protected cultivation methods are commonly used in agriculture and horticulture to extend the growing season, improve crop quality, and increase yields in regions with challenging climatic conditions.
In summary, greenhouse cultivation involves the use of permanent or semi-permanent structures with advanced environmental control systems for year-round production of a wide range of crops on a commercial scale. Protected cultivation encompasses a broader range of techniques and structures aimed at shielding plants from environmental factors, with varying levels of control and scalability.
