Principles of Protected Cultivation


The Protected Cultivation Structure is a structure covered with a transparent material for the purpose of admitting natural light for plant growth. Greenhouse cultivation achieves higher production of vegetables and other horticultural crops. Besides increasing production, it also improves quality of the produces and ensures round the year availability


The Protected Cultivation technology is more suited to vegetables crops (such as tomato, capsicum, chilies etc.), flowers (like rose, gerbera, carnation etc) and nursery for all vegetable crops, because of their small life-span. Greenhouse protects the crops from wind, rain, radiation, precipitation etc. It creates a microclimate surrounding the crop that helps the crop for maximum growth in terms of production and quality. Greenhouse also provides higher concentrations of CO2 to increase the production to its maximum level.


 By controlling environmental parameters (i.e. Temperature (0c), Relative humidity (%) and Light Intensity (lux)) and conserving of Carbon (CO2) inside the structure, following benefits may be obtained:


An efficient utilization of water, fertilizers and electricity.

Reduction in plant protection cost.

Crop(s) can be grown under adverse weather conditions

Higher average crop yield (30-40%) compared to open field cultivation

Improvement in  the quality of produce.

Increase in farmer’s income
