Weather based Agromet-Advisories (for the period ending on 25th July, 2018)

Advisory based on advices received from the subject matter specialists of agromet-advisory committee:

1.      Keeping in view of rainfall, farmers are advised to conserve rain water in the paddy fields by making broad and elevated bunds.

  1. Keeping in view of rainfall forecast farmers are advised to transplant paddy seedling as earliest in prepared fields with a spacing of 20 cm (row–row) x 10 cm (plant-plant). Standing water in the field should be 2.5 cm. If paddy nursery has been damaged due to high temperature; farmers are advised for direct sowing of germinated seeds of short duration varieties of paddy. For this field should be leveled. Recommended varieties are Pusa sugandh-5, Saket-4, Govind, P S -5, PRH-10. Fertilizers should be applied as per recommended doses. One packet of Blue Green Algae (BGA) per acre should be used for increasing nitrogen in the paddy field.

3.      Keeping in view of rain for next five days farmers are advised for sowing of maize. Recommended Hybrid: AH-421, AH-58 Composites: Pusa composite-3 Pusa composite-4. Seed rate 20 kg/ha. It is also advised to maintain row to row spacing of 60-75 cm. and plant to plant 18-25 cm. Spray of Atrazine 1-1.5 kg a.i/ha. in 800 litre of water is recommended just after sowing for effective weed control in maize, sorghum and bajra when sky is clear.

  1. Farmers are advised for sowing of bajra (Hybrid Bajra Pusa-605, Hybrid Bajra Pusa-415, Composite Bajra Pusa-383, HSV-67). Seed treatment is required for protection against Ergot. Seeds should be put in 10 % salt solution, light and damaged seed should be removed and remaining seed should be dried and treated with Thiram or Bavistin @ 2.0 gm/ kg seed to protect from seed borne diseases.
  2. This is most suitable time to grow fodder sorghum specially Pusa chari-9, Pusa chari-6 varieties. Seed rate should be 20-30 kg/ha. Lobia can be sown in this week for fodder.
  3. Farmers are advised for transplanting of Chilli, Brinjal and Early Cauliflower in raised bed. Proper drainage should be maintained in the field.
  4. Farmers are advised to start sowing of rainy season Cucurbits on ridge Hybrid varieties: Bottle Gourd- Pusa Santushti, Pusa Naveen, Pusa Sandesh; Bitter Gourd- Pusa Visesh, Pusa-2 mosumi; Pumpkin- Pusa Visvash; Ridge Gourd- Pusa Chikni, Pusa Sneh.
  5. Monitoring of rainy season cucurbits for insect-pest and disease to be done regularly. The creepers should be lifted above the ground on a trellis made of bamboo. Proper drainage should be done in the fields.
  6.  Bees are important source for pollination in vegetable crops therefore, bee keeping should be promoted. Constant monitoring of the crops should be done; Farmers should take advice from the nearest KVKs for use of insecticides and other information regarding the crops. Fruit flies infected fruits should be picked and buried in the soil. Protection of cucurbitaceous crops against fruit fly by use of bait trap (mixing juggary with Malathion 10 % and putting at different corners of the field) is advised.
  7. Farmers are advised for sowing of guar, cluster bean, amaranthus and ladyfinger. They are advised to procure good quality seeds from certified sources. Seed should be treated before sowing.
  8. This is suitable time for sowing of Radish- Versa ki rani, summer long, long chetaki Pusa chetaki; Spinach- All green; Coriander- Pant Haritama or hybrids on ridges. Proper drainage should be done in the fields.
  9. Constant monitoring of lady finger, chilli and cucurbitaceous crops against attack of mite and jassid is advised. Spraying of Phosmite @ 1.5 - 2 ml per litre of water is advised to control mite and spraying of Dimethoate 30 EC @ 2 ml/litre of water against jassid, when sky is clear.
  10. Sowing of baby corn (HM-4) and sweet corn may be done in this week.
  11. Farmers are advised to transplant the quality seedlings in the prepared pitsfor orchards.
  12. Keeping in view of heavy rainfall during next five days, farmers are advised to do proper arrangement for drainage in all vegetables, pulse, maize and nurseries of the crops. Farmers are also advised not to do irrigation and any type of spray in the crops.  
  13. Farmers are advised to do proper arrangement for storing rain water at one portion in the field; this water can be used for irrigation in the crops at suitable time during dry spell.
