    The productivity and quality of any produce is affected by genetic material, agronomical management and environment management. It is possible to cultivate any crops in any region of the world, provided that the polyhouse is properly designed and equipped to control the climatic parameters. The crop cultivated in the protected structure affects its economic viability. There is greenhouse effect in polyhouse with plastic film due to two different effects i.e. (i) a confinement effect, resulting from the decrease in the air exchanges with the outside environment; and (ii) an effect caused by the existence of a cover characterized by its low transparency to far infrared radiation (emitted by the crop, the soil and the inner greenhouse elements), but its high transparency to sunlight. Due to GH effect, the temperature inside the polyhouse is always more than the open field environment.
    The polyhouse works effectively during winter & rainy season but major challenges occur during summer season due to high temperature & light intensity. Though technologies are available to reduce the temperature inside the polyhouse during summer season but major challenges are fixed and operating cost.
    The major protection needed for cultivation are temperature [soil (minimum & maximum), air (minimum & maximum)], relative humidity, light (intensity & spectrum), carbon dioxide, wind speed, insect & pest management, rainfall, hill storm, snow, irrigation, weed management etc. The protection needed during cultivation depends upon the season of cultivation. Depending upon the requirement one or more parameter can be controlled or modified. It is also very important to understand the activities need to be conducted under protected system i.e. cultivation or nursery raising or drying etc.
    The other vital point need to be considered are activities month i.e. January, February, March, April, May, June, July, August, September, October, November, December. It may be that protected system need only for two months or may be five months or whole year. For example if someone wants to grow the vegetable nursery during peak winter season to protect from low temperature (soil & air), he may require protection only during December & January.
    The protection system that can be utilized are of two types i.e. category I (Medium cost natural ventilated polyhouse, Low cost multi-purpose polyhouse, Low cost detachable roof polyhouse, Low cost temporary shade net house, Rain shelter, Rain shelter & shade net structure, Protected structure with peripheral insect proof net, Plastic mulching, Drip/sprinkler irrigation etc.) and category II [Plastic low tunnel with different cladding materials (plastic film, shade net materials, insect net proof, crop cover etc.)]
    The enterprises or activities that can required protected system are cultivation [Conventional crops (tomato, capsicum, cucumber etc.), coriander leaf, spinach, cabbage, cauliflower etc.], Nursery raising (vegetables, fruits, flower), Drying etc.
    So, depending upon the enterprise or activities and utilization month, the proper protected system can be selected. The profitability and sustainability of enterprise or activities are very vital issue while selecting the protected system.

    Lot of pains were taken by you to explain the individual farmer requirements at a low cost and with multiple facilities in all the seasons. Hats off to you sir. Around 4 to 5 years back I laid a terrace garden on my car Garrage of 12X18 feet size covering all the sides with shade net of 50 %. Ofcourse I made small openings on North and South sides for ventilation and polination purpose. Inspite of that I faced inside heat problem. Then I shifted to open system on all side and covered only top with 50% shade net on Top. This gave me good results. I am doing this only for summer period March to June 2nd week in our area in Andhra Pradesh. Thank you for video.
