Improved Samba Mahsuri: a high yielding, bacterial blight resistant, fine-grain type, low glycemic index rice variety

Technology Profile

Spacing depends on several factors

  • With excellent cultural practices, the spacing may be slightly wider, say 20x15 cms but under sub-normal conditions, the spacing should be slightly narrower, say 15x10 cms.
  • Under good management and adequate nitrogen levels, the optimum spacing for varieties should be around 20x10 cms both for kharif and rabi crops.
Adopt proper spacing & ensure adequate plant population

Crop Establishment

  • At 2-5 leaf stage (20-25 days age) , uproot the nursery, trim the tips of seedlings and transplant.
  • Crop establishment is a very important part and hence utmost care is needed to ensure good crop establishment.
  • Synchronous planting should be followed which enables efficient use of irrigation, and reduces
  • incidence of pests.
  • Seedlings should be uproooted from the nursery without damaging the roots and with minimal
  • shock.
  • Make sure


  • 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 i

“Raise healthy nursery for healthy crop”

The seed rate naturally influences the growth of the seedlings. Thin sowing gives strong and tillered seedlings, whereas thick sowing results in thin and tall seedlings without tillers.
Thin sowing in nurseries is always better and it will produce strong and sturdy seedlings, which can withstand adverse climatic conditions better and produce better yields. Therefore, 40 to 60 grams of seed per square metre should be sown in the nursery beds. About 500 square metre area of nurs

Varietal selection

  • Select good quality & high density seed of a variety/ hybrid suitable to the location/season.
  • Varieties should be selected based on the environment and the season in which they are to be grown.
  • The most suitable variety is the one that best meets the farmer and the consumer’s needs. It may not always give the highest yield and the choice will be influenced by availability of water, either from rain or irrigation, soil type, field elevation and whether the r

“Plant pure, clean and healthy seeds”

Good quality seed reduces the required seed rate, produces strong healthy seedlings which results in a more uniform crop and higher yields.

Good seed is
  • clean - no stones or soil, weed seed,
  • pure - only seeds from one variety,
  • healthy - full big grains, same color, no cracks or spots


  • Select good quality seeds which are free from seed borne pests, diseases and weeds.
  • Select seeds which are bold, uniform in size and filled completely.
  • Seeds should be soaked in salt water and remove immature and chaffy seeds. Select only bold seeds and wash thoroughly with clean water for 2 - 3 times and dry under shade.
  • If seeds are farmer grown it should undergo germination test before using for sowing.
  • Select seeds which have good germination rate

“Levelled fields give the best yields”

A well prepared and leveled field gives a uniform,healthy crop that can compete with weeds, uses less water and gives higher yields at a lower cost.

A well prepared field has:
  • Many small soil clods to give good seed ‘soil contact’
  • No weeds
  • Harder layer at 10 cm to stop water percolation
  • Level and smooth surface after puddling
  • Well-constructed bunds

Land Preparation

  • Land preparation is done by ploughing, harrowing, and levelling the field to make it suitable for crop establishment.
  • Ploughing should be done 3-4 weeks prior to sowing.
  • Plough your field upto 12-15 cms deep and make sure the weeds and the stubble
