Weather based Agro-Advisories (for the period ending on 26th February, 2017)

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

1.      Keeping in view of increasing temperature, farmers are advised for light irrigation in all standing crops and vegetables as per requirement.

2.      In present weather condition constant monitoring of the wheat crop against rust disease is advised. If symptoms of black, brown or yellow rust appears spraying of crops with Dithane M-45 @ 2.5 grams per litre of water should be done. For yellow rust temperature should be between 10-20°C. Above 25°C the dispersion of yellow rust does not occurs. For brown rust the temperature should be between 15-25°C with humid weather conditions. For black rust temperature should be above 20°C with less humidity.

3.      Sowing of sugarcane can be done in vacant fields. Choose the best varieties recommended for the region, Such as Karnal-1, Karnal-2, Karnal-3, Karnal-4, Kernal-5, and Kernal-6 etc. Row to row spacing of 90 cm. Inter-cropping of short duration crops like lobia, guar, moong, spinach, amaranthus etc. may be done with sugarcane.

4.      Keeping in view of increasing temperature farmers are advised to start sowing of early crop of lady finger- A-4, Parbani Kranti and Arka Anamika cultivars. Before sowing seed should be treated with captan or thiram @ 2 gram/kg of seed and one packet of Bio-fertilizer/acre seed. Insure optimum moisture before sowing for proper germination of crop.  Seed rates should be 10-15 kilogram per acre.

5.      Due to dry and increasing temperature conditions, farmers are advised to monitor their vegetable and late sown mustard crops against attack of aphid.

6.      Sowing of French bean, cluster bean, summer radish is advised as present temperature is suitable for germination of seeds. Procurement of seeds should be done from a certified source.

7.      Farmers are advised to procure quality seeds for green gram and black gram from certified source and start sowing in prepared fields. Variety: - Green gram – Pusa Visal, Pusa Ratna, Pusa 5931, Pusa Baisakhi, PDM-11, SML-32, SML-668, Samrat and Black gram – Pant Urd 19, Pant Urd 30, Pant Urd 35, PDU-1. Seed treatment with crop specific Rhizobium culture as well as phosphorus solubilishing bacteria (PSB) is also advised. 

8.      In present weather conditions, transplanting of young seedlings of tomato, chilli crop may be done in prepared fields. Before transplanting root of the seedling should be dipped in the Imidacloprid 1% solution for 15-20 minutes for effective control of sucking pest. Use well decomposed FYM 10-12 ton/acre in the field at the time of ploughing.

9.      In present weather conditions, Start sowing of Cucurbits crops in this week. Seed should be treated with captan or thiram @ 2 gram/kg of seed before sowing. Use well decomposed FYM 10-12 ton/acre in the field at the time of ploughing.

10.  Constant monitoring of timely sown onion crop against attack of thrips and infection of purple blotch should be done. Spraying of Confidor @ 0.5 ml per 3 litre of water with sticky material (Tipol 1.0 gram /litre) is advised for thrips  and need based spraying of Dithane-M -45 @ 3 grams per litre of water with sticky material (Tipol 1.0 gram /litre) are advised for purple blotch disease.

11.  Installation of bird perches in tomato crop is advised to control fruit borer insect. Hand picking of damaged fruit and burying are advised. Installation of pheromone trap @ 2-3 traps per acre of crop field is advised for monitoring the tomato fruit borer. If pest population is high, spraying of Bt. 1.0 gram/litre of water or Spinosad 48 EC @ 1 ml. /4 litres of water is advised.

12.  Keeping weather in view, constant monitoring of inflorescence rotting disease in marigold crop is needed. If symptoms are found, spraying of Bavistin @ 1 gram\litre water is advised.
