Hi Deepak
Green Houses are built of a G.I. structure wherein crops are grown under a favorable artificially controlled environment and other conditions viz. temperature, humidity, light intensity, photo period, ventilation, soil media, disease control, irrigation, Fertigation and other agronomical practices throughout the season irrespective of the natural conditions outside.
Benefits of greenhouse farming
Yield increases by 5 - 15 times or even more.
Reduction in labour cost
Less fertilizer requirement, thus reduction in fertilizer cost.
Low water requirement thus saving in water.
Less chances of disease attack, thus reduction in disease control cost.
Higher Efficiency of Water & Fertilizer Use.
Cultivation in problematic topography.
Cultivation in problematic soil conditions.
Cultivation in problematic climate conditions.
Requires less area to get high yield and benefits.
Easy to operate, maintain & control.
Based on the cost of construction involved, there are 3 types of greenhouses.
1. low cost --Rs175-Rs 250 per sq m
2. Medium cost--Rs.525 to Rs 750 per sq m
3. High cost-- 2000-2500Rs per sq meter
