Weather based Agromet-Advisories (for the period ending on 09th October, 2022)

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

  • Keeping in view of light rainfall forecast, farmers are advised not to do any type of spray in the standing crops.
  • In present weather condition, field preparation should be start for rabi crops. Ploughing and planking should be done properly to conserve the moisture in the soil.
  • Field sanitization is advised before sowing ofrabi  Bunds, channels, uncultivated fields and field roads should be cleaned by removing weeds. Use fully decomposed FYM or compost before sowing of crops and vegetable as it improves physical and biological properties of soil and thus increases the water retention capacity as well as nutrient status of the soil.
  • Keeping in view of suitable weather conditions, sowing of mustard should be done in this week. Recommended cultivars:- Pusa Sarson-25, Pusa Sarson-26, Pusa Agrni, Pusa Taraka, Pusa Mahak. Seed rate: - 1.5-2 kg per acre. Moisture level in the soil should be appropriate for proper germination otherwise apply pre-sowing irrigation. Before sowing seeds should be treated with Thiram or Captan @ 2-2.5 g/ kg of seeds. Line sowing is beneficial. In non-spreading varieties, row to row spacing should be 30 cm and in spreading cultivars spacing should be 45-50 cm. After germination, plant to plant spacing should be maintained at 12-15 cm by thinning. Before sowing, soil testing for sulfur should be done and in deficient areas 20 kg sulfur per hectare should be applied at last ploughing.
  • This is suitable time for sowing of Before sowing farmers are advised to ensure optimum soil moisture for better seed germination. Recommended cultivars: - Pusa Pragati, Arkel. Seed should be treated with fungicides,Captan or Thiram @ 2.0 gm/kg and after that with crop-specific Rhizobium culture. A solution of jaggary and water after boiling should be allowed to cool down and then seeds along with Rhizobium should be thoroughly mixed. The mixture should be allowed to dry in a shade. It is highly recommended that the treated seeds should be sown after 24 hours of treatment.
  • Sowing of carrot can be done in raised bed. Recommended cultivars: - Pusa Rudhira, Pusa Asita. Seed rate-0 kg/ acre. Application of FYM, potash and phosphorus fertilizer is recommended. Seed treatment with Captan @ 2 gm per kilogram is advised. Farmers can do sowing by machine because it reduces the seed rate, improve the quality of produces and increase the yield.
  • Farmers are advised to monitor their fields regularly. Spray of NSKE (5%) is recommended against white flies and other sucking pests in all crop and vegetables.
  • In vegetables (brinjal, tomato etc) constant monitoring of borers by using pheromone traps 4-6 per acre is advised, If insect population is above ETL than spraying of Spinosad 1.0 ml/4 litre of water is advised against fruit borer and diamond back moth in cauliflower and cabbage.
  • Sowing of sarson saag- Pusa saag-1; Radish- Pusa chetaki, summer long, Pusa chetaki; Spinach- All green; Coriander- pant Haritma Fenugreek- PEB or other hybrids should be done on raised bed.
  • Farmers are advised to transplant green onion seedling in the prepared fields. Nurseries should be prepared in raised bed.
  • Farmers are advised for planting of early potato. The crop matures in 60-90 days. Recommended varieties: - Kufri Surya. After harvesting of potato crop, sowing of other rabi crop such as late wheat can be taken up.
  • Keeping present weather in view, farmers are advised to use light trap to keep a check on pest population. This causesless damage to useful insects. For making a light trap, a bulb should be fixed above a tumbler (either plastic or tin) having a mixture of water and few drops of any insecticide. The insects get attracted towards the light, fall in the solution and die.
  • In paddy crop constant monitoring of stem borer by using pheromone traps 4-6 per acre is advised, If insect population is above ETL, broadcast Cartap 4% granules @ 10 kg/acre for effective control.
  • Under the present weather condition, farmers are advised to monitor paddy crop for the infection of bacterial leaf blight. If farmers observe that paddy leaves are yellowing, water-soaked streaks are spreading from leaf tips and margins, becoming larger and sometimes leaves completely becomes yellow, than they are advised to spray solution of streptocycline 15 gram with copper hydroxide 77 WP @ 400 gram/ha mixing with 200 liters of water at 10-12 days intervals.
  • In present weather conditions, False smut may appear in basmati (paddy) crop. Symptoms include increase in grains size with brown colored fungus inside than spray of Blitox 50 @ 2 .0 grams per litre of water at 10 days interval (2-3 times) is advised.
  • In present weather condition, constant monitoring for brown plant hopper (BPH) in paddy field is advised. Farmers are advised to enter into the middle of the crop field and see mosquito like insect at the basal portion of the plant. If insect population is above ETL than spraying of osen (Dinotefuron) 100 gram /200 liter water per acre is recommended.
