Weather based Agromet-Advisories (for the period ending on 25th May, 2025) 

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

  • Optimum moisture level should be maintained in cucurbitaceous crops by light and frequent irrigation as dry conditions may lead to poor pollination and thus drop in yield of the crop. Keeping temperature in mind, light irrigation at short interval is advised in vegetable crops.
  • For green manure, sowing of dhaicha, senai etc may be done during this week. Seed rate for sanai is 60-70 kilogram and that of dhaicha is 50-60 kilogram per hectare. For adequate germination proper moisture should be maintained.
  • Sowing of fodder crops (gwar, maize, bajra) 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 cm and at row to row spacing of 25-30 cm.
  • Field preparation should be done for sowing of pigenpea and cotton in this week. Farmers are advised to procure good quality seeds from certified source. 
  • Keeping present weather in view, farmers are advised for harvesting of mature vegetables at morning and evening hours and keep harvested crops in shadow.
  • After harvesting of mature okra application of urea @ 5-10 kg/ acre should be done. Constant monitoring of crop against attack of mite is advised. If population is above ETL then, spraying of Ethion @ 1.5-2 ml/litre of water is advised when sky remains clear. 
  • To control shoot and fruit borer in brinjal and tomato crops, infested fruits and shoots should be collected and buried inside the soil. If pest population is high, spraying of Spinosad 48 EC @ 1 ml /4 litres of water is advised when sky remains clear.
