Abstract

Soil salinity is a great problem in south Khouzestan province. This study was conducted in years 2005-2007 in Shawoor Agricultural Research Station on a silty-clay soil with salinity 8 dsm-1, in randomized complete block design with split plot method, three replications and six PLANTING METHODS as broadcasting seeder + disk harrow (P1), broadcasting seeder + disk harrow + corrugate (P2), band seeding (P3) band seeding + corrugate (P4),double row at Farrow extremes (P5) and triple row at farrow extremes (P6), in main plots and four Hyola 401 SEED RATES as 6, 9, 12 and IS kg/ha in sub-plots respectively. The results showed significant difference between PLANTING METHODS. The change of P1 to P5 PLANTING METHODS caused plant per square meter, pods per plants, seed per pods increasing from 69.8. to 81.3, 55.8 to 74.3, 16.3 to 21.8 and increasing seed yield from 991.9 to 1967. 6 kg/ha. As the seed rate increased from 6 to 15, kg/ha, the number of plants per square meter increased ITom66.7 to 90.4 plants per mz, but there was no significant difference on pods per plants. There was no negative relationship between yield components, as seed rate increased the seed per pods decreased, and there was no significant difference in thousands seed weights, and seed yield increased from 1299.4 to 1599.4 in 6 and 12 kg/ha SEED RATES treatments. Finally, the highest seed yield 2134.3 was produced in double row at farrow extremes (P5) and 12 kg/ha seed rate which might be recommended in saline soils.
