Abstract

In order to investigate the effect of SOURCE and SINK relationship and the planting systems in fajr rice cultivar, an experiment carried out in rice investigations institute of Amol during 2010. This experiment performed as split plot in the basis of randomized complete blocks design with 3 replications. Different planting systems in three levels (Traditional planting, Improved planting and SRI planting) were in main plots and 3 levels of SINK- SOURCE relations (1/3 Panicle omitting, Flag leaf omitting and Control) were allocated in sub plots. Maximum GRAIN YIELD (873.9 gram at m2) produced under system of improved planting. Improved planting GRAIN YIELD had 18.3% and 25.1% significant increasing and compared to traditional and SRI respectively, because maximum and minimum number of empty spikelet in the panicle obtained for SRI and improved planting systems alternatively. Minimum number of empty spikelet in panicle gained after cutting 1.3 panicle that has 39.5 % decrease to control and shows SOURCE photosynthesis limitation in the fair cultivar.Cutting flag leaf 7.3% increased the Number of empty spikelet to control. It showed importance of flag leaf for filling spikelets. GRAIN YIELD 16/4% decreased by cutting flag leaf compare to control. Interaction effect of different planting systems and SOURCE- SINK relations was significant only on the number of empty spikelet on panicle,
