The nursery means a place where young plants or seedlings are grown for sale or for planting elsewhere.
Planting healthy seedlings in the main field leads to better harvests and good yields.
Some of the vegetable crops like tomato, brinjal, chili, cabbage, cauliflower, gourds, and flower crops like marigold seeds are raised in the nursery under 50% shade net to achieve maximum germination count and healthy plant establishment and then transplanted to the main field.
For vegetable seedlings production, the shade net structure was established in 0.25 acres at KVK, Tuniki.
Objectives
Supply of quality planting materials to the farmers
To enhance the crop yield and income of the farmer
Importance of vegetable nursery
Less loss of expensive seeds
Proper seed germination, uniform growth, least seedling mortality
Least pest and disease incidence
The root portion will not get damaged while uprooting seedlings from portrays.
The survival rate of seedlings is high after transplanting in the main field.
Procedure for raising of vegetable seedlings
Media preparation:
Soilless media like coco peat and vermicompost mixing with the ratio of 2:1 and enriched with biofertilizers like azotobacter, PSB & Zn solubulizing bacteria and Bio fungicides like Trichoderma viridi or pseudomonas flourscens at 15 to 20 days before filling in portrays.
To enrich the media, take 1 kg or lit of each bio fertilizer and bio fungicide for every 100 kg of media and mix well.
Everyday rotate the media once and sprinkle with jaggery water to maintain optimum moisture and also cover with gunny bags or leaves. It is better to prepare media under 50% shade net.
Filling of media in portrays
All the cells of portrays should fill with the enriched media in uniform and properly.
Seed Sowing
Each portrays having 98 cells and each cell depth is 3 to 4 cm. single seed should be placed at 2 cm depth in every individual cell and covered with media properly.
Germination
Seedlings should be irrigated regularly for better growth and development of the seedlings. Rose can or flush boom can be used to irrigate the seedlings. Excess irrigation is also dangerous for the growing seedlings as there might be chances of developing collar rot, root rot, and foliar diseases.
Nutrient management is important to raise healthy seedlings apart from the nutrients present in the coco peat or growing media. The nutrition is supplied through foliar application of panchaghavya@ 10 ml per lit and Fish amino acid @ 10 ml per lit alternate with 3 to 4 days intervals and also drench with jeevamrutham & waste decomposer (1:4 ratio) once in a week.

Pest and Disease Management
Drench with Trichoderma viridi @ 5ml per lit for management of soil-born diseases.
Spray fermented butter milk @50ml per lit and pseudomonas flourscens @5ml per lit for management of foliar diseases.
Spray neem oil 25ml per lit for the management of sucking pests and leaf-eating caterpillar infestation.
Transplanting
25 to 30 days old seedlings are ready for transplanting in main field.
