Protected Cultivation of Horticultural Crops (Paper Code: 17010719)

Introduction, history, definition, world scenario, greenhouse effect, uses of greenhouse, status and scope of greenhouse technology in India, choice of crops for cultivation under greenhouse, problems/constraints of greenhouse cultivation and future strategies; planning and designing for greenhouses: site selection, greenhouse orientation, plant, layout, greenhouse utilities– water, electricity, etc.; types of greenhouse: classification based on the shape, material, utility and covering material; considerations for greenhouse establishment; design load calculations;

materials for construction of greenhouse: fabrication of frame, covering/cladding of frame and environmental control system.

Management of greenhouse: temperature, light, relative humidity, ventilation, carbon dioxide, irrigation, nutrition, pests and diseases; methods of greenhouse cooling and ventilation – natural and forced ventilation; roof shading, lathe shades and evaporative cooling with fan and pad system, high/low pressure misting and fog cooling system, maintenance of greenhouse equipments, heating, heat distribution and conservation practices; carbon dioxide solid and carbon dioxide; light control in greenhouse– shading and selection of light source.

Growing media: soil culture, type of soil required, drainage, flooding and leaching, soil pasteurization, organic matter, pH control, pre-crop (base) fertilizer application and cultivation in peat moss and mixtures, rock wool and other inert media, nutrient film technique (NFT)/hydroponics.

Detailed production technology of vegetables: tomato, capsicum, lettuce and cucumber; cut flowers: rose, chrysanthemum, carnation, gerbera and anthurium; major diseases and insect pests and their management in greenhouse crops; marketing of greenhouse crops.
