I. Recommended crops: cabbage, cauliflower, broccoli, lettuce, bokchoy, garden pea, french bean and palak.
II. Recommended varieties (Cabbage): Pride of India, Golden acre, Pusa synthetic and Pusa mukta.
III. Recommended varieties (Cauliflower): Pusa deepali and Pant gobhi.
2. Nursery preparation: Prepare a raised nursery bed. Disinfecting the bed using 0.3% captan is desired.
3. Seed rate: Cabbage – 400-500g/ha; Cauliflower & broccoli – 400-500g/ha; Lettuce – 400-500g/ha; Palak – 15-20kg/ha; Lettuce – 400-500g/ha; French bean – 65kg/ha (bush type) and 30 kg/ha (pole type).
Plant Breeding & Genetics –Harendra Verma
1. Clean sanitation should be maintained in the rice field and apply 90kg of nitrogen through 200kg of urea in three splits when the sky is clear.
1st split dose : At transplanting stage 67kg urea/ha
2nd split dose : At 20 DAT 67kg urea/ha
3rd split dose : At 40 DAT 67kg urea/ha
2. Do not allow water logging in the maize field.
3. Apply spinatoram11.7% SC @0.25 ml/litre of water or cypermethrine 10EC or phosphomidan 100EC @1.5ml/liter of water for management of rice hispa.
4. Apply Alpha-cypermethrine 10% EC @2ml/liter of water or lambda-Cyhalothrin 10% EC 2ml/liter of water for management of rice leaf folder.
5. Do roughing in rice seed production field to maintain quality of seed.
Entomology – Moanaro Lemtur
1. In paddy, if scrapping or folded leaves are observed, spray Neem oil @ 2ml/ L of water and maintain the bunds and surrounding fields clean.
2. If withering of terminal shoots and bore holes in the shoots and fruits of brinjal are observed, first remove the infested fruit and clip off the withered terminal shoots and spray Spinosad 45 SC @ 0.75ml/L or Indoxacarb 14.5 sc @ 0.5 ml/L of water during evening hours.
3. In litchi, remove mite infested brown velvety leaves and burn the removed leaves and spray wettable sulphur 80WP @ 3 g/L, propargite 57 % EC @ 1.5 ml or or Novaluron 10 EC @ 1 ml/L of water prior to vegetative flushing.
4. In maize, if aphids infestation is observed, spray soap solution in the initial stage, but if the attack is severe spray Imidacloprid 17.8 SL @ 0.3 ml/L or Novaluron 10 EC @ 1 ml/L of water during evening hours.
Poultry –Mahak Singh and Talimoa
1. Poultry deep litter must be kept atleast 4-6 inches deep.
2. Since it is the season of high rainfall and humidity, the litter must be raked regularly and a fan may be run to dry the litter.
3. Deworming of birds must be done on schedule.
4. Debeaking of layer birds must be done if stocking intensity is high.
5. Laying birds must be provided bright light for 16 hours daily.
6. Laying birds need to be given layer ration for best results. Additional supplementation of calcium and other minerals may be done if needed.
7. Always be alert for disease outbreaks and unusual colour of droppings.
8. Feeders and drinkers must be disinfected regularly.
9. Indigenous immune boosters like turmeric may be added in feed from time to time.
Piggery – Mahak Singh and Talimoa
1. Keep the animals and animal sheds clean. Animal shed surrounding must be kept free from shrub and bushes.
2. Try to reduce mosquitoes and flies by use of suitable insecticides and repellents.
3. If pox like lesions is appearing in the body surfaces of pigs, daily bath with potassium permanganate solution will help reduce the severity. In rural areas where medicines are not available turmeric mixed in vegetable oil may be applied from time to time.
4. Deworm and vaccinate pigs on time.
5. Navel cord care, needle teeth cutting and iron supplementation of infant pigs must be done.
6. Market and kitchen waste must be boiled before feeding to the pigs.
Fishery – Jyotish Barman
1. Feeding fish with readymade fish feed or mixture of rice polish and mustard oil cake (in equal proportion) to be continued @ 10-12 kg/day/ha.
2. Application of Agricultural lime @ 27 kg/ha to be done in the morning hours preferably during 9 – 10 am. After 10 days of lime application, apply cow dung @ 200 kg /ha, Urea @ 25 kg/ha and SSP @ 20 kg/ha.
3. If rain continues, avoid lime application, manuring and fertilization.
4. In ponds, which receive direct sunlight throughout the day, provide some shelter for fish like putting floating aquatic plant, shade net over one-fourth area of the pond, etc.
5. If rainfall continues, prevent entry of surface runoff water into the pond. Strengthen the outlet.
6. Repair pond embankment that may have got damaged due to excessive rainfall. Periodically check the health status of fish.
7. Diseased or injured fish should be dipped in 1 ppm KMnO4 (Potassium permanganate) solution for 1 minute and then release into the pond.
8. Prune tree branches around the pond so that leaves do not fall on water. Make sure that the pond receives enough sunlight.
9. 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.
10. Partially harvest some of the fish that have weighed more than 600 – 700 g. do not remove more than 10 % of the total stocked fish.
