Plant spacing caused the variation in yield parameters. The plant spacing of 20 ×20 cm significantly recorded higher panicle length, panicle weight more spikelets panicle-1, grain panicle-1 as compared to 15 × 20 cm and 15 × 15 cm spacings. The wider spacing adopted appears to be an advantageous factor for better development of panicles, hence more panicle length, panicle weight, spikelets number and filled grains panicle-1. However, the case was just reversed for number of effective tillers m-2, being maximum under 15 × 15 cm spacing and lowest under 20 × 20 cm spacing. The possible reason may be the more number of plants with closer spacing than with wider spacing. Among the plant population tested 15 × 15 cm spaced crop gave significantly more grain and straw yields than 15 × 20 cm and 20 × 20 cm.
