Method of growing healthy and weed free saplings
A new method for obtaining healthy and weed-free new saplings, in which old sacks were used, was found to be less labor intensive, solve the weed problem and cost less than the new seedlings prepared by the existing method. The newly obtained saplings obtained by this method can be easily converted into S. R. In which 12-14 days old seedlings are used and existing seedlings are found suitable for planting in which 20-25 days old seedlings are used.Field and bed preparation for new plant:
- After harvesting wheat in the month of May, after irrigating the land, in the standing water in the field. Kg. The molded seeds are dispersed at the rate of . After 50-60 days, ploughed plants are mixed in the form of green manure by stirring the soil.
- One month before the planting of paddy, the field is prepared for the new saplings.
- After the goat comes to the nursery area, plow it 3 to 4 times with a plow and apply a pad.
- For better tillage and level surface, apply pad after cultivator.
- Where the plow does not reach the corners, grind the soil of those corners of the field with a shovel.
- This green manure improves nutrient availability and soil fertility. The green manure is left in the soil after plowing 3-4 times in order to decompose properly.
Nursery bed preparation
- For planting one hectare of field, 250 square meters nursery area is sufficient. Nursery area Total area for sowing seeds.
- 500 square meters with drains
- 250 square meters without drains
- Number of beds 20
- Bed Length Width 20m X 0.6m
- The distance between two beds is 60 cm for irrigation
- Size of Jute Sack 0.6m X 2m
- Number of pieces of jute sack in a bed 10
- Seed quantity 600 g per bed (at the rate of 12.5 kg seed per hectare)
Manure per bed
- Total manure of cow dung 8 kg per bed
- On top of 3 kg jute sack pieces
- Under 5 kg jute sack pieces
- NPK 200 g per bed Zinc 25 g per bed
- Per he. For the cultivation of the field, soak 12.5 kg of paddy seeds in a solution of 20 liters of water for 12 hours.
- Remove the extra water from the seeds and keep them in moist jute bags for germination. The moisture level in the bag should be maintained.
Sowing and subsequent care
- Prepare nursery beds 0.6 m wide and 20 m long and 4-5 inches high
- Spread 5 kg of rotted manure on nursery beds at the rate of 5 kg zinc, 25 gm and NPK 200 gm per bed. Soak the pieces of jute sacks in water for 4 to 5 hours.
- Spread the soaked jute pieces on the nursery beds.
- Spread the germinated paddy seeds evenly on the pieces of jute sacks
- Cover these seeds thinly with ground dung manure.
- Take special care to prevent the damage caused by birds until the new saplings become green. The new plant will easily get its food from the dung manure that is poured below it while pushing its roots through the jute sacks.
- The outbreak of weeds on the nursery of paddy sown on jute bags is negligible. Because it is not possible for weeds to cross the jute bags.
- By this method the new saplings are ready for planting at the age of 15 days.
Following are the advantages of growing new saplings by this method.
- Jute bags act as a hindrance to weeds and do not allow them to germinate. It is noteworthy that this is a major problem of traditional nurseries where it is difficult to distinguish rice and weed plants during early stages.
- The roots penetrate through the wet jute bags and continuously take up the nutrients present at the bottom of the bags. The air also enters better from all around the jute bags, due to which the plant grows at a faster rate. The uprooting time is also reduced by half as compared to conventional nursery, which requires less labor.
- In this method, the soil does not stick to the roots of the plants, so it is easy to separate each plant, which is very important from the point of view of seed production.
- Jute bags allow easy and careful uprooting of the plant without causing any mechanical damage to it and its roots and thus reducing the risk of outbreak of bacony disease.
- Genetic purity is of paramount importance in raising nursery for seed crop. The problem of voluntarily growing plants can be successfully solved by this method as the layer of jute sacks does not allow the germination of seeds and the voluntarily growing plants can be removed very easily by hand.
For the treatment of termites, apply Chlorpyrophos at the rate of 3.25 liters/ha on first and second irrigation.
