Abstract: About 500 nurseries have come up around Bangalore and Kolar for vegetable crops. These nurseries raise the seedlings in portrays under shade net house. Each vegetable nursery is producing about 30,000 to 3,00,000 seedlings per day. These nurseries have become popular due to high price of seed Rs.10 to 60 thousand per kg and lower germination 60 to 90% . The farmers are purchasing healthy seedlings at Rs.0.25 to 2.00 per seedling for hybrid and F1 varieties of various crops. The seedlings are raised in portrays (98 cell) and 3 to 4 laborers are required to manually fill, dibble and seed/sow about 300 protrays in a day. Nurseries for ornamental plants exist in all the major cities and nurseries for fruit crops are available in all the fruit growing belts. The ornamental plants are generally raised in pots and fruit nursery plants/ grafts are raised in polythene bags. The machinery for media sieving, mixing, portray filling, dibbling and seeding for vegetable nurseries have been developed. The media siever sieves 1 tonne/hr of the sand, vermicompost and farmyard manure. It is operated with 1 hp electric motor and can be operated manually also. The media mixer has a capacity of 0.5 tonne/hr and is operated by 2 hp electric motor. The various constituents of media e.g. sand, FYM and vermicompost etc. can be mixed in required ratio. The dibble board dibbles 100 portrays per hour and rotary dibbler 300 portrays /hr.The vacuum seeder sows 200 portrays/hr and is operated by 1 hp vacuum pump or compressor. The automatic media mixer, portray filler, dibbler, seeder with watering attachment sows about 400 protrays/hr and needs 4 electric motors of 1.5 hp and a vacuum pump or compressor of 1 hp. The trolleys for seeded trays and seedling portrays has also been developed. The seedling depopper has a capacity of 50 protrays per hour. The rain protection structures for nursery beds has also been developed. The bag filler for fruit and ornamental nurseries has been developed and has a capacity of 700 bags per hour. The commercially available pouch form and fill machine can be modified and used to make the plastic bags and filling these with media. Upto 1000 bags can be filled in one hour. The size of the bag/pouch can be varied. The bags/ pouches are made from continuous LDPE film. The media sand, vermicompost, FYM can be sterilized using a baby boiler. The pot fillers, transplanter for transplanting the seedlings to bigger pots and automatic grafting machine for ornamental and fruit crop nurseries are yet to be developed. The portray destacker and washers also need development
