Abstract
The investigation to determine the effect of size of spacing on the grain yield and ripening of rice cultivar Basmati-370 revealed that 20 x 20 cm plant spacing produced significantly higher paddy yield (4.18 t/ha) than 15 x15, 25 x 25, 30 x 30 and 40 x 40 cm spacings which yielded 3.78,3.71,3.47 and 3.20 t/ha, respectively. Narrower plant spacing significantly produced more sterility and opaque Kernels which were reduced by increasing plant spacing between hills and rows. The occurrence of abortive kernels was not affected significantly by the size of nutritional area.
