PrintPrintSend to friendSend to friend

1. Vasambu (Acotus calamus) powder and cow urine are mixed in the water that has been boiled and cooled over night and the seeds are soaked in the solution.  The floating seeds are removed. The remaining seeds are used for sowing. This serves the dual purpose of seed selection and treatment of seed borne disease. This is practiced in Tamil Nadu. 

Reported by R. Nagarajan(2003)

2.  Higher seed rate is adopted by the farmers  of Tamil Nadu as dense  planting  of paddy  gives higher  yield.
Reported by Aravanan(2003)

3.  In some parts of the high altitude in red and black soils of Arunachal Pradesh   tribal  farmers used to broadcast paddy seed with  ash to over come  dry spells.

4.   For seed selection, the field is identified during   growth stage having uniform and better growth and harvested separately.
Reported by K.Lakshmana(2003)

5.  Through physical observations on the basis of  phenotypic  characters, farmers select/ demarcate  healthy plots  for seed purposes. This is often  done one month prior to harvesting. Healthy plots  that are free from  pests and disease attack are selected.
