Weather based Agromet-Advisories (for the period ending on 10th December, 2023) 

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

• Keeping weather conditions in view, farmers are advised to irrigate wheat crop which is in CRI stage (21-25 days after sowing). After 3-4 days of irrigation broadcast of second dose of nitrogen should be done.
• Keeping in view of temperature farmers are advised for sowing of late wheat soon. Seed rate: - 125 kg seed per hectare. Recommended cultivars: - H.D.-3059, H.D.-3237, H.D.-3271, H.D.-3369, H.D.-3117 WR-544, P.B.W.373. Seed should be treated with Bavistin @ 1 gram or Thiram @ 2.0 gram per kg 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. 
• Keeping in view weather, farmers are advised for application of fertilizer should be done also earthing up may be done in potato crop.
• 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 appear than spray of 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.
