Design of Micro Climatic Environmental Conditions Inside Greenhouses For Cultivation of Tulip Flowers

Abstract


Tulip is one of the nature’s beautiful creation and represents the largest ornamental crop worldwide. It ranks first among ornamental crop for its brilliant colour and exquisite flowers. Tulips are excellent for cut flowers ,beds, pots and are grown in open as well under protected conditions(greenhouse).Holland is the largest producer of tulip flowers and bulbs and has become the back bone of flower industry in Netherlands.Recently it is gaining popularity among the flower growers in Kashmir valley because of increasing demand of its cut flowers and bulbs. Its cultivation is a lucrative business and flowers are sold at 50 to 75 INR per flower both in national and international market.

Keeping demand in view there is a need to produce tulips round the year. In Kashmir valley tulips are grown only in limited period i.e, from February to May, as the environmental conditions are best suited for tulips growth during these months. Presently there is no such controlled condition system for tulips in India except countries like Holland, China, New Zealand. In green house not only the temperature but also velocity, humidity and mass flow as well can be controlled. This system can be utilized in such a way that the tulip flowers can be produced throughout the year. The demand for tulip flowers varies throughout the year and the flowers can be supplied to the market throughout the year with the help of this system. This paper presents the design of micro climatic environmental conditions inside greenhouses for cultivation of tulip flowers.
