Weather based Agromet-Advisories (for the period ending on 18th May, 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.
  • Keeping in view of temperature, farmers are advised for light irrigation as per requirement in all vegetable and standing Irrigation should be done in the morning hours or in the evening hours.
  • For green manure, sowing of green gram, cluster bean, senai, gwar 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, cluster bean) 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 in view of high temperature forecast, 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.
  • 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 when sky is 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 is clear.
  • 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.
  • 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.
  • After harvesting of rabi crops farmers are advised to test their soil from certified agencies and to do laser leveling in their field if required.
