Abstract

In order to evaluate the effects of SOWING DATE and PLANT DENSITY on the yield of SOYBEAN LINES, a research was conducted at Miandoab Agricultural Research Station. The experimental design was factorial with three replications and repeated for two years (2001-3). The SOWING DATE included three dates (April 21, May 15 and May 20) and sowing density included three levels of 30, 40 and 50 plants per m2 with two advanced SOYBEAN LINES from the crosses of Williamsx Chippewa and Williams x Collombus. During the growth period all agronomical characters were measured.Combined analysis of varianes indicated that the effects of PLANT DENSITY, SOWING DATE, line, year x SOWING DATE, PLANT DENSITY x line and SOWING DATE x line x year on GRAIN YIELD were significant. At 50 plants per m2, the line Williams x Chippewa produced highest GRAIN YIELD (2866 kg/ha). The highest GRAIN YIELD (3667 kg/ha) was obtaind in the second SOWING DATE of the second year for the line originated from the Williams x Chippewa. It was concluded that the line from the Williams x Chippewa cross was high yielding than the other line. This line also produced the highest yield in the SOWING DATE of May 15at the density of 50 plants per m2.
