    Okay, It is well known to all that organic fertilizers keep the soil quality good and help to produce any crops with better quality in terms of taste, ingredient and nutrients. BUT have their any comparative study about this? Having a densely populated country like Bangladesh can we rely only on the local variety having low production? Then is it possible to make the nation self sufficient in food? Why Govt. of Bangladesh is encouraging all the scientists to introduce HYV in order to make the country independent in food security? Have any Private or NGO Research organization become able to find out local/indigenous variety which can produce same amount (in kg) in a cycle? Better we can motivate people to look after and take care the local variety like the HYV/Hybrid. We can use the recently introduced saline tolerant rice variety of BINA 7, BINA 8 and BINA 9. Otherwise, dependency on other nations for rice would be increased and the price of rice would be crossed Tk. 100/per kg in Bangladesh. We will be faced a great problem for food insecurity, because rice is our main food. Thanks and regards.

    Most of the rice research institutes have been working on producing salt-tolerant rice varieties in recent years, and there are now quite a few being tested or released for multiplication. The rice institutes (eg. BRRI, IRRI) will have information on yields under different conditions. We do not know of comparative studies between the yields of traditional rice varieties and the new HYVs under salty and other conditions, although there are studies of the characteristics of salt-tolerant traditional varieties. Overall, we cannot claim that traditional varieties will have higher yields than the new salt-tolerant varieties (after all, these will be bred from traditional varieties crossed with high yielding varieties). Some traditional varieties may well have a better taste and other good characteristics; some may perform better than other ordinary HYVs in salty conditions, and they are also essential to retain biodiversity. But the yields published for new varieties are high – eg 2.5-3.5 ton/ha in salty and up to 7.0ton/ha in normal conditions for the new IRRI variety. Md Alamgir mentions three new varieties and there is also the BR 47 variety available from BRRI (Bangladesh Rice Research Institute) in Bangladesh that is supposed to be salt-tolerant. If you need more information, try contacting BRRI directly. In terms of the price of seeds, it will depend partly on whether the new varieties are stable cross HYVs – so the farmers can save seed and replant the following season, or whether they are hybrids which will quickly lose vigour and will need to be purchased every season.

    this is a brilliant iniciative and could be used in many other LEDC's to combat food production issues in coastal areas.

    Adapting rice to saltier water is a very good idea. it will help us come when the world ends in 2012. smart thinking who ever thought of this!
