بررسی و تعیین آرایش کاشت لاین های امیدبخش سویا

This expriment was study in order to select planting date of soybean lines L.11 and L.17 in tow part as RCBD as with four replications.It was done during 2003-4 in khorramabad location. Plant density (b1=30, b2=40 and b3=50 plant m-2) and row distantce (S1=50cm with one plant row, S2=50cm with two plant rows, and S3=75cm with two plant rows) were as factorial. The results of compound analysis showed that: a)Line L.17: The effect of plant density and row distance on seed yield was significant. b2 and S2 produced the highest seed yield (3449 and 3580 kg.ha-1 respectively) among others. d2S2, d3S1 and d2S1 prodused 3842, 3617 and 3448 kg.ha-1 seed yield, respectively. There was nosignificant diffrence between treatments in 1000-seed weight but d2S1 with 136g 1000-seed weight and d3S3 with 25.5% seed oil were the best. b)Line L.11: The effect of plant density on seed yield was not significant, but the effect of row distance was significant (1% probility) S1 with 3292 kg.ha-1was the best. d3S2, d3S1, and d2S2 produced maximam seed yield 3402, 3355 and 3323 kg.ha-1, recpectively. No significant difreance was showed in 1000- seed weight, but d1S3 with 103g was higher than others d3S3 produced the highest oil seed percentage (25.14%). The d3S2 treatment with high oil seed for both lines L.17 and L.11 is interoduced for khoramabad location. Key words: Plant density, Plant Row distance, Soybean Varieties.
