Weather based Agromet Advisories (for the period ending on 20th December, 2017)

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

1.   Keeping in view of forecasted temperature for next week will be below the optimum temperature required for the wheat germination. Therefore, farmers who are interested for late sowing of wheat are advised to increase the seed rate. Seed rate: - 125 kg seed per hectare. Recommended cultivars: - P.B.W.373, WR-544, U.P.2338, U.P.2425. Seed should be treated with Bavistin or Thiram @ 2-2.5 g 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.

2.   Thinning and weeding is recommended in late sown mustard crop. If low temperature continues for two weeks white rust infection may start. So keep observation on leaves for white rust appearance.

3.    Transplantation of onion should be done in this week. Folidol dust 10 kg.\acre is recommended for effective control of tunnel borer and other soil insect.

4.   Irrigation in timely sown potato crop is advised. Application of fertilizer should be done after irrigation. Earthing up may be done in potato crop.

5.    Due to high relative humidity, infection of blight may occur in potato and tomato. Constant monitoring is advised. 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.

6.     Transplanting of mature seedlings of tomato, cauliflower, cabbage, knolkhol and broccoli crop may be done in the raised bed.

10.  Due to high relative humidity farmers are advised for constant monitoring of inflorescence rotting disease in marigold crop.
