Question

Net house farming is also called as-
A. Greenhouse farming
B. Polyhouse farming
C. Polytunnel farming
D. Precision farming

Answer 1

Hint: Net houses are naturally ventilated climate-controlled houses made up of any woven material or agro nets that have a variety of applications like growing vegetables and fruits for the export market, floriculture, etc. This house frame provides support for cladding material, an appropriate microclimate conducive to the plant growth, and is designed to protect against wind, rain and crop load.

Complete Answer:
Let us analyze the correct answer,
- Option A: The farm practice of growing crops within sheltered structures covered by a transparent, or partially transparent material is called greenhouse Farming. The main purpose is to provide favorable growing conditions and protect crops from unfavorable conditions. Net houses are also included in these shelter houses and thus this is the correct option.
- Option B: The farm practice of growing crops in sheltered houses that are raised by a structure with bamboo or steel pipes, covered with polythene plastic or glasses is called polyhouse farming. Net houses are not included here and thus this is an incorrect option.
- Option C: In polytunnel farming, small polytunnels made from steel and covered in polyethylene are used. These are semi-circular, square, or elongated in shape. Therefore, this is an incorrect option.
- Option D: The farming management concept based on observing, measuring, and responding to inter and intra-field variability in crops is called precision farming. It involves measures of small-scale soil cultivation, sowing, fertilization, application of pesticides, and other operations. Therefore, it is an incorrect option.

Thus, the correct option is A. Greenhouse Farming.

Note: These houses are easy to install and give more productivity even in adverse weather conditions and help crops to grow longer. The degree of sophistication also varies in net houses from simple to highly sophisticated and computerized with fully automated drip and foggers systems.
