NURSERY MANAGEMENT

PrintPrintSend to friendSend to friend
  • Nursery should be prepared nearer to the mainfield so as to minimize the shock during transplanting.
  • Utmost care should be taken while preparing the nursery as it is the place where rice seedlings grow and establish themselves.
  • Prepare the type of nursery based on your resources such as water, type of soil etc eg : Wet bed method is practiced in areas of water abundance and Dry bed method is practiced in areas of less water and where the soil is loamy or clayey.
  • Appropriate seed rate (15-20 kg/ha) should be used based on the variety/ hybrid selected. Farmers use very high seed rate, which is not required and wasteful.
  • For good preparation of your nursery, Plough the soil thoroughly 3 to 4 times and level it perfectly. Make channels for irrigation water and drainage.
  • Incorporate one tonne compost/FYM per 1000 m2 bed during last ploughing/puddling.
  • Broadcast the sprouted seed 5kg /100 sq.mt of soil. Make sure the seeds are free from weed seeds. For 200 sq.mt of nursery bed apply 2kg. Nitrogen (1kg at the time of broadcasting the seed and another after 12 to 14 days) 1kg P2O5 and 1kg Potash. In cold prone areas apply double dose.
  • Allow it to dry for some time and give slight irrigation at first leaf stage.
  • Weeding should be done once in 15-20 days as it helps seedlings grow effectively without competition for nutrients, water etc.
  • If zinc deficiency is noticed spray 2 g ZnSO4 dissolved in 1 liter of water. In case of dry nursery if Iron deficiency is noticed spray 20 g / 1 lt. (2%) ferrous sulphate solution.
  • Protect your Nursery against bird damage of seed by netting or taking colour ribbons.
  • Apply Carbofuran 3 G granules 10 days after broadcasting the seed per cent of nursery @160g or Monocrotophos 1.6ml or Chloropyriphos @ 2.0 ml per liter of water. Apply Carbofuran 3 G granules @ 160 g per 40 sq.mt of nursery week days before uprooting the nursery.
  • Seedlings should be uprooted with soil and transplanted immediately so as to minimse the shock to the seedlings. See to it that the time gap between uprooting the seedlings and transplanting is less.
