Weather based Agromet-Advisories (for the period ending on 12th December, 2021)

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

  • Keeping in view of threat of COVID-19 spread farmers are advised to follow the government guidelines, personal hygiene, use mask, ensure hand washing with soap at reasonable interval, social distancing during picking of vegetables and other agricultural operation in all crops.
  • Keeping in view of temperature farmers are advised for sowing of late wheat soon. Seed rate:- 125 kg seed per hectare. Recommended cultivars: -D.-3059, H.D.-3237, H.D.-3271, H.D.-3117, WR-544, P.B.W.373, U.P.2338, U.P.2425, Raj. 3765. Seed should be treated with Bavistin @ 1 gram or Thiram @ 2.0 gram per kilogram of seed. Application of Chlorpyriphos (20EC) @ 5 litres per hectare with pre-irrigation water or by spraying is recommended before sowing in the fields having perennial problem of termite infestation. Recommended dose of fertilizer for N: P: K is 80, 40 and 40 kg / hectare.
  • Thinning and weeding is recommended in late sown mustard crop. If low temperature continues for two weeks, white rust infection may start. Therefore farmers are advised to keep observation on leaves for white rust appearance.
  • Transplantation of onion should be done in this week. Farmers are advised to uses fully decomposed FYM and potash fertilizer in the fields before transplanting.
  • Due to high relative humidity, infection of blight may occur in potato and tomato. Farmers are advised to do constant monitoring in both the crops. If symptoms appears than spray of Carbandizam @ 1.0 gm / litre of water or Dithane-M-45 @ 2.0 gm / litre of water is recommended.
  • Transplanting of mature seedlings of tomato, cauliflower, cabbage, knolkhol and broccoli crop may be done in the raised bed.
  • Constant monitoring of leaf feeders in cole crop is advised. If pest population is above ETL than Spray of B.t. @ 1.0 gram\ litre of water or Spinosad @1 ml \ 3 litre of water is advised.
  • Intercultural operations in vegetables are advised to remove the weed. Irrigation in timely sown vegetables crop is recommended after that apply optimum dose of fertilizers.
  • Wrapping of plastic sheets around mango trunk should be done for preventing climbing of young mealy bugs. Apply grease to seal any cracks in the polythene sheets.
  • Due to high relative humidity farmers are advised for constant monitoring of inflorescence rotting disease in marigold crop.
  • Farmers are advised for, not to burn the residue of kharif crops (paddy) in the fields because it not only pollute the environment but also causes the severe health (respiratory) problems. The smog formed due to burning of residue reduces the solar-radiations received to the crops and decrease the process of photosynthesis and evapotranspiration, which affect the quality and quantity of all crops. Farmers are advised to mix the residue of kharif crops in the soil. It increases the soil fertility. It can be used as mulching for deceasing soil evaporation and to conserve soil moisture. Pusa decomposer capsule can be used @ 4 capsule /ha for decomposing the residue of the paddy.
