Abstract
This experiment was carried out to study the effects of planting density and amount of fertilizer applied on the morphological, physiological and physical characteristics of barley culm. The results are summarized as follows: 1. Heavy application of fertilizer increased the diameter of the inside and outside thickness of culm, dry weight per unit culm, culm length, spike weight and number of per hill. 2. Thined planting density increased lodging resistance. But lodging resistance in sparse-planted plot of 20cm was almost the same as that in the plot of 15cm. 3. In the heavy fertilized plot weight of culm at breaking, bending moment of culm atbreaking, secondary moment of inertia and section modulus increased more than those in the standard fertilized one. As a result heavy application of fertilizer gave high lodging resistance. On the other hand thined planting density increased the above-mentioned physical characters of culm. 4. In the case of dense planting lodging index became higher in standard fertilized plot, but in the case of sparse planting over 10 x 10cm there were no significant differences in lodging index as affected by amount of fertilizer applied and planting density. 5. Grain yield was increased by heavy application of fertilizer and proper planting density was 5cm or 10cm for the safe maximum yield.
