Thus an entire plant can be produced from a single leaf. The rooted petiole of a leaf can be used as a root stock in the production of grafts. The technique works primarily in dicotyledonous species. The same technique can also be used in sugarcane. A business based on these items has a potential annual market of Rs.
Rainwater serves as source of distilled water.
A laboratory producing just a few hundred plantlets per week costs less than Rs.5 hundred thousand to set up. The ex vitro plantlets are used only as mother plants, which are multiplied in a nursery under exclusion of pests and diseases, and the second or third generation is sold to farmers. The cost per plant can be reduced drastically in this way. Using three times the recommended dose of fertilizers, along with the necessary micronutrients, we get three times the yield in most crop species. Capital cost of the system is Rs.50 per sq.m and the annual running cost is Rs.5 per sq.m.
