During July 2023, normal to above normal rainfall is most likely over some areas of North East India and below normal rainfall is most likely over many areas of North East India. Normal to above normal maximum temperatures are likely.
Plant Breeding & Genetics –Harendra Verma
1. Variety suitable for our region -
Medium duration variety of rice - RC Maniphou-7, Pusa Sughand-5 (Aromatic).
Maize - RCM-76 a composite variety
Sesame – Amrit and Prachi
2. Arrange quality seeds of variety suitable for our region for crops viz rice, maize, sesame, soyabean etc from authentic source. Also arrange fertilizers and manure in adequate quantity.
3. Seed treatment should be carried out with Vitavax (carboxin + thiram) 2-3 g/kg seed.
4. Apply zinc in nursery of rice @ 2kg/500m2 area.
5. Apply vermicompost in nursery for good health of rice seedlings.
6. Transplant seedlings at the age of 20-25 days and transplant only healthy seedlings.
7. To avoid attack of termites, dip the seedlings in a solution of Chlorpyrifos 50EC, Cypermetrin 5EC, having concentration of 0.4% (4ml/liter of water) for 10 minutes before transplanting.
8. Treat the roots of seedling with bavistin fungicide solution having concentration of 0.4% to avoid occurrence of bakanae disease and other fungal diseases.
9. Do transplanting and sowing of various crops in line by maintaining an isolation distance of 30*10 cm for rice and sesame; 60*20 cm in maize for proper air circulation and to avoid disease incidence. It will also provide opportunity for easy intercultural operation such as weeding, earthing-up etc.
Agroforestry – Pempa Lamu Bhutia
1. Planting should be done when the rains have fully set in and the soils are soaked to a depth of 30 cm.
2. Choose tree species that are native to the region and are suitable for the local climate, soil conditions, and intended purpose such as afforestation, reforestation, or agroforestry. Consider factors such as growth rate, tolerance to drought or waterlogging, and their ecological and economic benefits.
3. Ensure adequate spacing between trees to allow for healthy growth and prevent overcrowding. The specific spacing requirements may vary depending on the tree species and intended objectives.
4. To prevent erosion during heavy rainfall, implement soil conservation practices such as staggered trenching and terracing before planting trees on steep terrain.
5. Plant trees in staggered rows on sloping land.
6. While planting, firmly compact the soil around the seedlings, ensuring there are no airspaces inside, and cover the soil up to the collar area of the seedlings.
7. Control weeds around young plants. Mulching or manual weeding can be effective methods during rainy season for weed control.
Entomology – Moanaro Lemtur
1. In cowpea if aphids infestation is observed, clip off the infested tips and pods in the initial stage and spray soap solution but if the attack is severe spray Imidacloprid 17.8 SL @ 0.3 ml/L or Novaluron 10 EC @ 1 ml/L of water.
2. Replace yellow sticky trap and Cue lure Fruit fly trap in the field.
3. If fruit fly trap is not installed in cucumber, sponge gourd, bitter gourd, bottle gourd, pumpkin and pointed gourd field install it @ 10 traps/ha.
4. If webbing, scrapping, holes or caterpillars are observed in vegetables spray NSKE 5% or neem oil @ 2ml/L or Spinosad 45 SC @ 0.75 ml/L of water and if it is severe spray Indoxacarb 14.5 SC or Flubendiamide 39.35% SC @ 0.5 ml/L of water during evening hours.
5. If curling and drying of leaves are observed in sponge gourd, ridge gourd, cucumber, bottle gourd and pumpkin spray Imidacloprid 17.8 SL or Fipronil 2.92 % EC @ 0.3 ml/L of water during evening hours.
6. In maize, dust the plants with ash to protect from Fall Army Worm (FAW) and if some white patches or holes with faecal pellets are observed in the leaves spray Neem oil @ 2ml/ L or Spinosad 45 SC @ 0.75ml/L of water during evening hours.
Poultry –Mahak Singh and Talimoa
1. Hot and humid weather stress could affect production adversely. Therefore give multivitamins and electrolytes in water.
2. Rake deep litter properly atleast once a week and sprinkle bleaching powder or lime periodically.
3. Run a ceiling fan to help in proper air circulation and faster drying of litter material.
4. Avoid overcrowding to prevent disease outbreaks.
5. Vaccinate and deworm bird’s regularly.
6. Do not mix birds of different age groups.
7. Provide atleast 1-16 hours of bright light.
8. Laying birds should be provided with sufficient vitamins & minerals to help in maintaining good egg production.
9. Always maintain cleanliness and disinfection of drinkers and feeders.
10. Mixing turmeric in feed once or twice weekly will help boost immunity of the birds during the rainy season.
Piggery – Mahak Singh and Talimoa
1. Whitewash the walls of pens to lower the bacteria load in the animal pens.
2. Disinfect feeding and drinking troughs regularly.
3. Do not let dogs, cats, rodents, birds or random visitors enter the pig shed.
4. Avoid vaccination in early pregnancy.
5. Deworm at 5-6 months intervals.
6. Provide multivitamins and oral electrolytes to combat weather stress.
7. Avoid inbreeding.
8. Serve animals in heat 24 hours after standing heat is observed.
9. Needle teeth nipping and navel cord care should be carried out with utmost care.
10. Remember to feed iron supplements to infant piglets.
Fishery – Jyotish Barman
For ponds where fingerlings have been stocked
• Feeding daily to be continued @ 3% of total weight of the fish stocked.
• Application of agricultural lime @ 27 kg/ha to be done in both stocked and un-stocked ponds. Lime should be applied only on sunny day in the morning hours preferably during 9 – 10 am. Lime application should not be done on rainy or cloudy days.
• After 10 days of lime application, apply cow dung @ 200 kg /ha, Urea @ 25 kg/ha and SSP @ 20 kg/ha.
• If the temperature is too high, put some floating aquatic plant in one corner of the pond to provide shelter for the stocked fish. The covered area should not exceed one-fourth of the total water surface area.
• Prevent entry of surface runoff water into the pond. Strengthen the outlet.
• Continuously monitor fish activities and movement every morning, noon and evening. At early morning hours the fish may come to surface to gulp air or breathe. If such symptoms are observed, immediately mix the pond water by splashing or by pumping fresh water from nearby sources.
• Sometime there may be excessive growth of algae (algal bloom) due to manuring and leftover feed in the pond. In such condition, the pond water turns deep green/ brown and there will be layer of algae on the water surface. Stop feeding and fertilization during this period till the bloom disappears.
For ponds where fingerlings have not been stocked
• Ponds that are filled with water, stocking to be completed. Release fingerlings in early hours or in the evening, when the temperature of water is cool.
• For ponds with 4-5 feet depth, 3-4 species composition should be stocked.
Sometimes due to heavy rainfall, there are chances of water overflowing in some ponds. This may result in escaping of stocked fish. To avoid escape of fish, provide net/mesh barricade or fencing at the point of overflow or around the pond surface area.
