  1. Greenhouse Protected Agriculture for High Value Crops

  2. Introduction • What is a Green House ? • A Green House is a structure covered with a transparent material in which various crops are grown under a system of farming know as Protected Cultivation • The Structure is also referred as Glass House / Poly House, depending upon the Cladding material used. • Under Green House Technology favorable Micro Climatic conditions are created suiting to the crops raised. • Green House Protect the Plants from adverse climatic conditions such as wind , low temperature, rainfall, excessive radiation, extreme temperature and pests. • Green House Technology facilitates off –season production of crops to realize higher returns.

  3. Advantages of Greenhouses : • Ensures multi-fold increase in crop output compared to open cultivation • Facilitates year round production of selected crops. • Mitigates impact of adverse climatic conditions in respect of certain type of Green House • Facilitates substantial control of pest & diseases . • Facilitates optimum utilization of all inputs. • Facilitates raising of off-season production of crops. • Aids in Nursery Propagation, Hardening of Plants • Facilitates High-Tech Cultivation Practices like Hydroponic , Aero-ponics and Nutrient Film Techniques.

  4. Greenhouse type based on shape: • Lean type greenhouse. • Even span type greenhouse. • Uneven span type greenhouse. • Ridge and furrow type. • Saw tooth type. • Quonset greenhouse. • Interlocking ridges and furrow type Quonset greenhouse. • Ground to ground greenhouse. Lean to type Even span type Others

  5. 1). Green house type based on Utility • Greenhouses for active heating. • Greenhouses for active cooling. 2). Green house type based on construction • Wooden framed structure. • Pipe framed structure. • Truss framed structure. 3). Green house type based on covering material • Glass glazing. • Fibre glass reinforced plastic (FRP) glazing • i. Plain sheet • ii. Corrugated sheet. • Plastic film • i. UV stabilized LDPE film. • ii. Silpaulin type sheet.

  6. a) Low cost or low tech Greenhouse • Low cost greenhouse is a simple structure constructed with locally available materials such as bamboo, timber etc. • The ultra violet ( UV) film is used as cladding to cover the roof and sides. • Increasing or decreasing the temperature and humidity mostly by opening side walls. • Suitable for cold climatic zone. • Suitable for high value vegetable crops during off- Season. Low cost green house with Casuarina poles

  7. Tomato cultivation in Low tech Greenhouse – In side view Out side view – Low tech Green house

  8. b) Medium-tech Greenhouse ( Semi- Automated) Less expensive compared to High- tech GH. Control possible manually/ Semi- automated. GI material can be used for frame work. Exhaust fans, thermo- stat to control temp. Cooling pads/ mist system to control humidity. Sun light control by regulating shade nets. Need more attention in operations. Suitable for Dry & composite climate zones Medium -tech Greenhouse

  9. C.) High- tech Greenhouse ( Fully Automated) Fully automated controls. Less attention in operations. Uses computer software for controls. More initial cost. More suitable to high end applications . ( Floriculture, Hydroponics/ Aeroponics) Requires assured availability of power. Hi-tech green house

  10. d). Shade net Greenhouses Suitable for commercial nurseries / vegetable crops during hot weather . It provides protection from excessive sunlight, heat, cold,  wind, frost, and hailstorm. It also offers protection from insects, birds etc. Low Cost of construction Shade net Greenhouse

  11. Components of typical Greenhouse

  15. Construction Cost

  16. Project Study – Cut Roses • Cut Roses Cultivation in 1 ha under Greenhouse Conditions. • Benefit/ Cost Analysis. Source: NABARD, Model Bankable projects, (www.nabard.org)

  17. Project Components • Fixed cost –Permanent items like Civil structure, equipment, planting material • Recurring cost –Cultivation expenses, post- harvest expenses, over heads, Logistics • Projected yield & Income • Estimate the total production expected in different years and the realization expected through sales. • Benefit/ Cost Analysis • Margin money • 25% of the total cost that has to be invested by the entrepreneur. • Repayment • Principal and interest are to be repayable in seven years with a moratorium for the first year on interest and for 2 years on principal.

  27. APSHM(AP- State Horticulture Mission)www.apshm.ap.nic.in Pattern of Assistance * Only 50% to 75% shade net is to be used. Maximum ceiling :- 1000 sq. mtrs per beneficiary under shade net house & Green House.

  28. Crop Suitability • Low Cost Greenhouse/ Shade net: • Nurseries of high value vegetables – Tomato, Chillie etc • Nurseries of high value fruits- Papaya, Strawberries etc • Ornamental nurseries • Vermiculture

  29. Crop Suitability • Medium Cost Greenhouse: • Seed industry – Seed purification, Screening tests. • Vegetable cultivation – Value crops like Melons, Capsicum, Beans, Cucumbers, Tomato • Export Floriculture- Rose, Carnations, Gladiolus • Tissue culture- Hardening of Banana, Straw berry

  30. Crop Suitability • High cost Greenhouse: • Hydroponic / Aeroponic cultivation ( Soilless) • Orchid cultivation • Tissue culture • Mushroom culture – ( Button mushroom) • High value vegetables: Tomato, Peas

  31. Benefits / Risks Risks High initial investments More need for skilled man power Suitable for limited crops High maintenance cost. Difficult to maintain optimum growing conditions Fertilizer deficiencies/ excess Release of toxic gases Power failures Susceptibility to certain pests( Mites) and fungal diseases. Tall growing tendency of the plants Difficulty in inter cultivation and land preparation Damages due to high wind gales/ Fire/ Other calamities Benefits Risks • Off- Season cultivation • Enhanced productivity / Quality • Efficient use of inputs • Effective control of pests and Diseases • Implementation of tissue culture techniques • Commercial nurseries of high value crops • Hydroponic/ Aeroponic cultivation of crops
