Yield of traditional rice varieties

Green revolution in India had started with agenda of increasing grain production after independence. To increase grain production the following were done 1. Increasing farm area 2. Irrigation facilities with big dams and channels so that instead of single crop 2 crops could be cultivated comfortably 3. Introduction of HYVs (High Yielding Varieties) which matured in short duration and produced heavy yield under chemical fertilisers.

It has been told that yield of traditional rice varieties is low and to increase the production dwarf varieties of rice called HYVs like IR8 was produced which gives better results on application of fertilizers. IR8 gave 5 tons per hectre without fertilizer and 10 tons per hectre with chemical fertilizers. The traditional varieties were giving only 1-2 tons per hectre, as per the history.

On introducing the semi dwarf verieties farmers stopped cultivation of traditional varieties. It is said that India had 1,10,000 varieties of rice and kerala had 4000 varieties.

But recent reports show that there are many traditional varieties which provides 5-10 tons of yield per hectre. Here is a summary of performance of Indigenous Rice Varieties under SRI method, provided by Dr.Norman Thomas Uphoff of Cornell University, USA.

So if there were alternatives available locally, then what was the reason for going for dwarf varieties and resulting in chemical pollution and wiping out all the diversity?Probably if local varieties were used to achieve the production, then the diversity would have preserved and Indian agriculture would have been different. For any country locally available seeds/diversity is the best.

  • These varieties were collected from various states (donated by various people and institutions). Some are grown for the first time and some are already grown for more than one season in Sambhav.
  • Since Sambhav has a small patch of land (1.5 acres) where it is growing more than 350 varieties for seed only. So the calculations are made following established method only. These are not actual productions.
  • Performance of many varieties, specifically upland varieties are not yet compiled.

Hi Chaitanya,

Thanks for the reply. I will contact him.
Btw I have got this variety from a local organization in Hyderabad and cultivated in my farm. It is going good so far now.
But wanted to know details like composition, health benefits, marketing etc. (atleast in brief if not in detail) so that it helps me during post harvest period to update people who are going to take it from me and also encourage other farmers to take up this seed.

I am also planning to develop desi seeds in our farm this rabi season (atleast 10-20 varieties) so that a local seed bank of desi seeds can be developed at my end and capture in detail about each seed.

Hi Chaitanya,

Nice to hear that, would love to see some photos of this rice. Good to know that you are developing a seed bank of traditional varieties. I have seen personally that traditional varieties are sturdy compared to HYV and tastes excellent.
