Though both of these rice are used but in which parameter direct seeded rice better than transplanted rice? Economic or yield, in which parameter? Need suggestions.

In general, Dry direct-seeded rice is an good alternative cropping method that should require less water and labor than classical transplanted-flooded rice.
Direct seeded ric eha sout-yielded the transplanted rice...plus the reduced cost of production..
In Egypt, Transplanted rice is the popular method for Egyptian rice cultivars. But from my point of view, direct- seeded rice is better than transplanted rice to reduce the water requirements and minimize the production inputs of rice yield.
Depends on the variety. Some variety grow and yields better in direct seeded whether other perform better in transplanted.
Very interesting questions....actually what is happening, our scientific research findings or recommendations of bestest farmers practises at grass root level changes in accordance with socioeconomic conditions though it changes due to climatic and environment conditions also...both the establishment methods either TPR or DSR having it's own merit as well as demerits... During 1970 or 80 decades, we used to read the definition of agronomy as a branch of science deals with principle and practices of soil water and crop management to enhance yield and productivity while no a days, die to climatic changes as well as depletion of natural resources to a greater extent, we add something to complete agronomy definition...what we are adding is to enhance production and productivity by optimizing use of natural resources so as to sustain ecosystem...so it is clear that DSR have it's own advantages as it avoid 3 basic operation like puddling, transplanting as well as maintenance of standing water up to a definite period of time...means DSR is saving resources like water, labour and other also.. methane production in DSR is very minute as compared to TPR owing to puddling and denitrification under extremely water conditions...water table is going down day by day and also soil organic matter is reducing as we are going to follow conventional tillage operations...no doubt TPR system has lesser infestation of weeds as compared to DSR because of using 25 days old seedlings and puddling, which ensure competitive advantages against weed as 25 days old seedlings have good tolerance and also weed seeds and propagules die due to anoxia conditions...proper weed management in DSR by integration of several weed control options can minimize losses due to weeds, hence one can get yield of DSR as similar as TPR...
Again there are many more merits and demerits of these two establishment methods...
