چکیده

in order to investigation the effect of row spacing and seeding rate on alfalfa (medicago sativa l. cv. mesasirsa), an experiment was carried out at the research farm of khouzestan agricultural research center from 2000 to 2004. this research was conducted in the form of  a split plot design in a randomized complete block, with four replications. main plot was three row spacings (50, 60 and 70 cm) and sub plots were five seeding rates (5, 10, 15, 20, and 25 kg seed ha-1). results showed that the highest seed yield obtained in the second year. seed yield and racem per m2 increased with row spacing decreasing. seeding rate did not have any significant effect on pod per racem, seed per pod and seed weight. the interaction of year and treatments on whole of traits was not significant. it was observed that correlation among seed yield and yield components was positive and significant. it was concluded that with using 15 kg seed ha-1 the highest seed yield obtained to increase in racem per m2 and seed weight.

RICE CULTURE Influence of Row Spacing and Seeding Rate on Grain Yield of Hybrid Rice

Recent interest by producers, researchers, and industry personnel concerning the use of grain drills utilizing 7-in. versus 10-in. row spacing have raised questions as to the optimal drill-row spacing for rice. With the increase in hybrid rice produced and the associated low seeding rates, questions arose regarding the response of these cultivars to row widths. The objective of this study was t...
