Weather based Agromet-Advisories (for the period ending on 18th April, 2021)

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

 

  • Keeping in view of threat of COVID-19 spread farmers are advised to follow the government guidelines, personal hygiene, use mask, ensure hand washing with soap at reasonable interval, social distancing during harvesting and other agricultural operation in all crops.
  • Before storage, grains should be properly cleaned and it should be dried to the recommended level of moisture content not more than 12%. Godowns should be properly cleaned by removing all the grains and other storage matter of previous crop. Cracks and crevices of the walls should be cleaned and repaired. Farmers are advised to treat gunny bags with 5% Neem solutions. The gunny bags should be dried in the sun so that eggs and pupating stages of insects as well as inoculum of diseases get destroyed. farmers are advised to keep harvested crops and grains in the protected place.
  • In present weather condition, harvesting of mature wheat crop is advised. Harvested crops should be properly tied to avoid being carried away by winds. Adequate drying of harvested grains before storage should be done.
  • In this week sowing of green gram should be done. Variety: - Pusa Visal, Pusa 672, Pusa 9351, Punjab 668. Seed treatment with crop specific Rhizobium culture as well as phosphorus solubilishing bacteria is also advised. Adequate moisture should be maintained for maximum germination of seeds.
  • Direct sowing of french bean, amaranthus, vegetable lobia, lady finger, bottle gourd, cucumber, ridge gourd and summer radish is advised as present temperature is suitable for germination of seeds. Adequate moisture should be maintained for maximum germination of seeds. Procurement of seeds should be done from a certified source.
  • Sowing of green manure crop is advised where harvesting of rabi crop is over. For green manuring cluster bean, daincha, senai, lobia etc may be sown and ensure proper moisture for proper germination and growth of the crop.
  • Sowing of gwar, maize, bajra, cluster bean as fodder crops may be done during this week. Adequate moisture should be maintained for maximum germination of seeds. Sowing should be done at a depth of 3-4 centimeters and at row to row spacing of 25-30 cm.
  • Incidences of powdery mildew disease in cucurbitaceous crops and late pea may be occurring at present temperature. If symptoms found more than, spraying of Carbendazim @ 1.0 gram per litre is advised when sky remains clear.
  • Constant monitoring of lady finger crop against attack of mite is advised. If population is found more than spraying of Ethion @ 1.5-2 ml/litre of water is advised when sky remains clear. Due to prevailing high temperature, light irrigation at short interval is advised.
  • In onion crop, fertilizer should not be applied at this stage as it will hamper corm growth and encourage vegetative development.
  • To control shoot and fruit borer in brinjal and tomato crops, infested fruits and shoots should be collected and buried inside the soil. Installation of pheromone trap @ 2-3 traps per acre is advised for monitoring of borers. If pest population is high, spraying of Spinosad 48 EC @ 1 ml /4 litres of water is advised when sky remains clear.
  • Deep ploughing of fields after harvesting of rabi crops is advised so that eggs and pupating stages of insects and weed seeds are destroyed.
