Weather based Agromet-Advisories (for the period ending on 29th May, 2022)

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

  • High temperature is suitable for deep ploughing of fields after harvesting of Rabi It helps in destroying the eggs and pupating stages of insects and weed seeds.
  • 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 for sowing of pigenpea may be done in this week. Farmers are advised to procure good quality seeds from certified source. Before sowing pigeon pea seeds should be treated with crop specific Rhizobium culture and Phosphate Solublesing Bacteria (PSB). This treatment increases the crop production. Pigenpea varieties- Pusa 2001, Pusa991, Pusa992, Paras manak, UPAS 120.
  • Keeping in view of forecasted high temperature, farmers are advised for harvesting of mature vegetables at morning and evening hours and keep harvested crops in shadow.
  • 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. Due to prevailing high temperature, light irrigation at short interval is advised in vegetable crops.
  • 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. Due to prevailing high temperature, light irrigation at short interval is advised.
  • 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.
  • After harvesting of rabi crops farmers are advised to test their soil from certified agencies and to do laserleveling in their field if required.
