Nursery management

 
•  Select well filled high density seed of variety suitable to the location/season by
    treating in salt water solution of specific gravity 1.08 (20 lt per 5 kg seed) prepared by
    dissolving 80 g common salt in one litre of water.
•  Plough the nursery area (1000 m2 per ha. of main field) at optimum moisture to get  
    fine tilth and prepare raised seed beds of 1.0 to 1.5 m width and convenient length
    with provision for 30 cm wide irrigation/drainage channels in between.
•  In case of wet nurseries puddle the ploughed land twice to get a soft puddle, level
    and prepare seed beds of convenient size with provision for irrigation/ drainage
    facility.
•  In all the types of nurseries incorporate one tonne compost/FYM per 1000 m2 bed
    during last ploughing/puddling
•  Apply DAP @ 108 kg ha-1 to supply 20 and 50 kg ha-1 of nitrogen and phosphorus
    before sowing the seeds and incorporate. Apply muriate of potash (MOP)@ 85 kg ha-1
    to supply 50 kg ha-1 potassium.
•  In locations of low temperature regimes (15-25 oC) apply double the dose of
    phosphorus in two or three dressings.
•  For dry nurseries spray 0.5% solution of ferrous ammonium sulfate twice at weekly
    interval to prevent iron deficiency. Intermitant flooding of dry nurseries also prevents
    occurance of iron deficiency.
•  Top dress nitrogen as urea to supply 25 kg N/ha at 2-3 leaf stage.
•  Broadcast seed of location specific, high yielding and chosen variety @ 30-40 kg/ha in
    dry nursery or sprouted seed in wet or dapog nursery.

Fertilizer Management in Modified Mat Nursery

1. Five days after sowing of seed on modified mat nursery, remove the cover and flood the nursery. Maintain 1 centimetre water level around the mats.

2. Then, drain the water 2 days before removing the seedling mats for transplanting. If seedlings show yellowing after 7 days, it means that they lack Nitrogen.

3. It can be solved by sprinkling the seedlings with 0.5% urea solution. Simply dissolve 1.5 kgs of Urea in 300 litres of water and sprinkle over 100 m2.

Sowing of Seeds in Modified Mat Nursery

1. Sow the pre-germinated seeds uniformly on prepared seed of modified mat nursery. Sprinkle soil and pat gently to embed them at about 2-3 centimetres into the soil, and then sprinkle water immediately. 2. Remove the wooden frame and repeat laying the soil mixture and sowing seeds until you have finished the whole nursery area. 3. If wooden frames are not used, banana stalks can be used instead. Simply create a fence around the nursery using banana stalks pegged with wooden sticks, pour the soil mixture inside, and level before sowing. 4. Cover the nursery with banana leaves or plastic sheeting at the end.

Nursery Bed Preparation for Modified Mat Nursery

1. Modified mat nursery needs 4 cubic meters of soil mix for every 100 m2 of nursery area.

2. Mix 7 parts soil with 2 parts rotten and well-decomposed chicken manure, and 1 part fresh or charred rice hull.

Preparing the nursery area

3. Prepare a 100 m2 nursery area to plant one hectare. Select a levelled area in backyard or in the main field.

4. Level seedbed and spread banana leaves or plastic sheeting on top to prevent the roots of the seedlings from penetrating into the soil.

5. Lay the soil mixture. It can be done this with or without using a wooden frame. For those using a wooden frame, place the frame on top of the banana leaves.

6. The frame should be half a meter long, 0.3 meter wide and 4 centimetres deep, divided into equal segments. Then, fill the frame to the top with the soil mixture prepared.

Seed Rate of Modified Mat Nursery

1. In modified mat nursery 12 to 25 kgs of good quality seeds are required with a minimum germination rate of 80%.
2. It is important to use good seeds because they result in use of lower seed rate, more uniform germination, less replanting, fewer weeds, healthy seedlings, and 5–20% higher yields.

Modified Mat Nursery

 

1. Modified mat nursery technology establishes seedlings in a layer of soil mix, arranged on a firm surface. 2. It uses less land and requires fewer seeds and inputs, such as fertilizer and water, reducing nursery costs by up to 50%. 3. After 15-20 days, the seedlings reach the four leaf stage, which favours quick establishment in the field and rapid growth and are ready for transplanting. 4. Modified mat nursery technology is much quicker than the 25-35 days required for traditional wet-bed nurseries.

Fertilizer Management and Transplanting of Dapog Nursery

1. For every 100 m2 area of the seedbed, about 0.5-1.0 kg of Nitrogen, 0.5 kg of Phosphorous and 0.5 kg of Potash fertilizers should be applied.

2. In addition to chemical fertilizers, FYM might be applied at 250 kg/100 m2 before seed bed preparation.

Watering in Dapog Nursery

1. The germination seeds should be sprinkled with water by using a rose can and pressed down lightly by hand or with a wooden flat board twice a day for 3 to 6 days.

2. This operation keeps the roots of the seedlings is contact with water retained on the surface and prevents their drying.

Nursery Bed Preparation for Dapog Nursery

1. Nursery beds are prepared on a concrete floor or a raised soil bed covered with polyethylene sheets.

2. 25 to 35 sq. m. of area is enough to raise seedlings.
