  18. 18.  Under the Tegra technology, paddy seedlings are grown in a special media comprising straw, soil, nutrients, chemicals and other such things in a tray.  The seedlings are developed in a nursery and then replanted after 15 days with a special transplant machinery. Syngenta offers the technology at Rs 75 a tray and an acre requires 70 trays  There are reportedly seven centers in Tamil Nadu for providing transplanting services  Now cost of crop care concept works out to Rs 6000/ac  The transplanter service provider will get Rs 20/tray Video

In addition there was no rat problem” Area covered: 100 acres of (100 farmers) SRI in pillekothur, Pathakotta, Podur, Gangapuram, Gobachandram, Kamandoddi and Kaverinagar. Each machine covered 2.5 ac per day and farmers were charged Rs.1500/ac.

  37. 37. Hurdles faced in the farmers’ field Sieved soil was used in many locations to avoid small stones if not hinders planting Incidence of sucking pest in the nurseries probably due to enriched rooting media Experienced drivers only could achieve square planting in the entire field Main field preparation to the needed condition was a problem and convincing the farmer to dry the field was a major hurdle Being canal irrigated area, water management during initial period was so cumbersome Matching sowing of nursery and main field preparation was also tough; so as to plant at appropriate age of seedlings
