Abstract: The rice ratooning practice is unfamiliar in the framing community. It need to be introduced for achieving yield targets, because neither the vertical nor the horizontal increase of rice production could keep pace with this thrust even if the yielding ability has more or less reached in the plateau. Locklodged rice ratooning in this regard might be an alternative approach. With minimum care, no land preparation and transplanting, it can yield at least half of the main rice crop. The attempt was made to exploit the relationship of yield contributing characters and physiological parameters with each other to understand the mode of relationship with yield attributes, which could be guideline for breeders, agronomists and plant physiologists. The study envisaged that the locklodged rice grain yield was associated with all the agronomic and physiological traits including plant height, leaf dry matter total dry matter, leaf area index, relative growth rate, crop growth rates, biomass duration, 1000 grain weight, seed length, panicle length, number of panicles per plant, tiller number at harvest, and ratoon rating. Whereas, the grain yield showed non-significant relationship with net assimilation rate. These all the growth, yield and physiological parameters were also associated with each other except net assimilation rate of the crop.
