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

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

  1. Farmers are advised for harvesting of the matured mustard as earliest. 75-80 percent of the pods (Siliqua) turn parchment brown in colour is the right time for harvest. Farmers are advised not to allow the crop to over mature, which cause loss of grains due to scattering. Immediate threshing after drying is advised. Attack of painted bug will be more if crop is kept in the field for long time after harvest.
  2. In view of increasing temperature farmers are advised to irrigate wheat crop in milking and grain filling stage. Light irrigation should be done when wind velocity remains calm.  
  3. Farmers are advised to start sowing of green gram. Variety: - Pusa Visal, Pusa Ratna, Pusa 5931, Pusa Baisakhi, PDM-11, SML-32, SML-668, Samrat. Seed treatment with crop specific Rhizobium culture as well as phosphorus solubilishing bacteria is also advised. Farmers are advised to ensure proper moisture before sowing for optimum germination.
  4. Installation of bird perches in tomato, pea, brinjal and gram crops 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 fruit borer. If pest population is high, spraying of Bt. 1.0 gram/litre of water is advised. After 15 days if pest population is more than ETL, farmers are advised to spray Spinosad 48 EC @ 1 ml. /4 litres of water.
  5. Monitoring of vegetables crops against attack of aphid is advised. In present temperature conditions, aphid population will gradually diminish. Control measures should be initiated if pest population is high. Spraying of Imidacloprid @ 0.25 ml per litre of water in vegetable crops after harvesting of mature fruits should be done. In vegetable crops a waiting period of one week should be followed after spraying.
  6. In cucurbitaceous crops, if attack of red pumpkin beetle is found than, spraying of Diclorvos 76 EC (DDVP) @ 1 gram per litre of water is advised.
  7. Present temperature is suitable for incidences of powdery mildew disease in cucurbitaceous crops and late pea. If symptoms found than, spraying of Carbendazim @ 1.0 gram per litre is advised.
  8. In cucurbitaceous crop which are 20-25 days old application of 10-15 gram urea/plant is advised.
  9. Present temperature is suitable for germination of french bean (Pusa parvati, Contender), amaranthus (Pusa kiran, Pusa lal chaulai), vegetable lobia (Pusa komal, Pusa sukomal), lady’s finger (A-4, Parbani Kranti and Arka Anamika), bottle gourd (Pusa naveen, Pusa sandesh), cucumber (Pusa uday), ridge gourd, sponge gourd (Pusa sneha) and summer radish (Pusa chetki). Procurement of seeds should be done from a certified source. Farmer are advised to ensure proper moisture before sowing for optimum germination.
  10. In onion crop, light irrigation is advised. Fertilizer should not be applied at this stage as it will hamper corm growth and encourage vegetative development. 
  11. In present weather condition constant monitoring of timely sown seed onion crop against attack of thrips should be done. If population is more, spraying of Carbaryl @ 2 grams per litre of water with sticky material (Tipol 1.0 gram /litre) is advised. Monitoring of seed onion crop against infection of purple blotch should also be done. If population is more than need based spraying of Dithane M -45 @ 3 grams per litre of water with sticky material (Tipol 1.0 gram /litre) are advised.
  12. Temperature is suitable for sowing of fodder maize (Variety – African Tall) and lobia. Sowing of HM-4, hybrid cultivar of baby corn may also be done in this week.
  13. In mango and citrus, during flowering irrigation should be avoided for good fruit setting. Constant monitoring of mango mealy bug and leaf hopper are advised.
  14. Farmers are advised for transplanting of marigold seedling in fields for summer crop.
