Weather based Agromet-Advisories (for the period ending on 30th September, 2018)

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

1.      In present weather condition, field preparation should be started for rabi crops. Ploughing and planking should be done properly to conserve the moisture in the soil.

2.      Field sanitization is advised before sowing of rabi crop. Bunds, channels, uncultivated fields and field roads should be cleaned by removing weeds also use fully decomposed FYM or compost before sowing of crops and vegetable as it improves the physical and biological properties of soil and thus increases the water retention capacity as well as nutrient status of the soil.

3.   Keeping in view of suitable weather conditions, sowing of mustard should be done in this week. Recommended cultivars:- Pusa Tarak, Pusa Mahak. After ploughing the field planking should be done. 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.

4.    Sowing of carrot can be done in raised bed. Recommended cultivars: - Pusa Rudhira, Pusa Asita. Seed rate-4.0 kg/ acre. Application of FYM, potash and phosphorus fertilizer is recommended. Seed treatment with Captan @ 2 gm per kilogram is advised. Now day’s machine for sowing of carrot is available. Farmers can do sowing by machine because it reduces the seed rate, improve the quality of produces and increase the yield.

5.     Farmers are advised to monitor their fields regularly. Spray of  Thiamethoxam @ (2.0 g / 10 lit. of water) or NSKE (5%) is recommended against white flies and other sucking pests in all crop and vegetables.

6.    In present weather conditions, false smut may appear in paddy. Symptoms include increase in grains size with brown colored fungus inside. Spraying of Blitox 50 @ 500 grams per acre at 10 days interval (2-3 times) is advised.

7.      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.

8.      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.

9.      Sowing of sarson saag- Pusa saag-1; Radish- Pusa chetaki, summer long, long chetaki; Spinach- All green; Coriander- pant Haritma Fenugreek- PEB or other hybrids should be done on raised bed.

10.  Farmers are advised to transplant green onion seedling in the prepared fields. Nurseries should be prepared in raised bed.

11.  Planting of early potato is advised to the farmers. The crop matures in 60-90 days. Recommended varieties: - Kufri Surya. Thereafter, sowing of other rabi crop such as late wheat can be taken up.

12.  Farmers are advised to use light trap to keep a check on pest population. This causes less 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 kerosene oil. The insects get attracted towards the light, fall in the solution and die.

13.  Marigold plantation should be done in this weather conditions.
