DETAILS OF INNOVATION
 
Title and Nature of Innovation : 
  • Refinement of SRI (System of Rice Intensification)
  • Seed rate @1.25 kg/ha
  • Wider spacing @ 50cm X 50cm
  • Drudgery reduction and labour   
  • Saving in transplanting and harvesting practice
Description of innovation:
The  Seed rate used was @1.25 kg/ha  for Normal wetland nursery @12.5 cents area. The seedling age was 15 days and 40000 Seedling/ha was required for transplanting. A wider spacing @ 50cm X 50cm was followed. Due to the refinement of SRI technology drudgery was reduced  and labour saving in transplanting and harvesting practices was observed. We achieved 40-100 productive tillers/hill, 100-400 grains/panicle and the crop yield benefit was upto 6250 – 10000kg/ha.
 
 Problem Statement (How a particular problem was solved by the innovation):
  • Reduce the seed cost in term of reduced seed rate
  • Drudgery reduction and labour saving in transplanting and  harvesting practices during the labour crisis  periods 
  • Reduced labour and labour cost 
  • Less pest and disease incidence 
  • No lodging
  • No rat damage
  • Increased yield over conventional method
Process of technology development :
  • Frequent visit was made to Tamil Nadu Rice Research Institute, Aduthurai and visited various field trials conducted by Department of Agriculture and interacted with the Scientist.
  • Mini kit experiments were conducted over the past seven years in my field to fine tune the seed rate and spacing with help of TRRI and other scientist.
  • Reducing the seed rates from 75 kg/ha to 1.25 kg/ha and adoption of wider spacing (50cm x 50cm) instead of 25cm x 25cm was attractive.
Economics:
  • No need of Rogueing 
  • Suitable for seed production
  • More monitory  return by mean of marketing paddy as seeds
Recognition for the innovation : Field trial were monitored by  Agriculture Officer and scientist and the same was published in News paper, TV and radio etc.,
