بررسی تعیین بهترین آرایش کشت لاین های جدید سویا

To determine the best arrangement for soybean new lines (2002) - 70036 11/6- P and (2001) B-23/13-70060 were planted the form of split plot design with four replications carried for about two years. Treatments include distance between rows 20, 30 and 40 cm in the main plot and seed rate 60, 70 and 80 kg were considered sub-plot.Also this experiment was separate for each line. In the middle of the may preparing the soil with a heavy disk and two disks perpendicular style with its disruption and added the fertilizer ( 150 kilograms phosphate and 100 kilograms, sulfate two potas per hecter) in the early of jone cropping was started , N stabilizer seeds with bacteria were also stained.Growth recorded during the different period after reaching cropping, removing both lateral line and 5 / 0 m R Srkrt took two and yield analysis and comparison of design methods The average treatment method in Duncan 1% and 5% levels were measured. At the end of the second year of analysis of variance in order to find and determine the best arrangement was planted.Experiment with a total area of 2500 square meters is about margins. 2001 best performance related to the amount of seed treatment with 20 cm 60 kg ha-efficiency4.618 tons per hectare respectively. All treatments between different rows of seed rate 70 kg ha have been better than others. the best performance in 2002 related to the amount of seed treatment with 20 cm 60 kg ha-efficiency 3.947 tons per hectare respectively. Density correlation with yield, weight of thosend seed, charcoal rot infection rate, plant height and pods stuck Combine both lines were studied. Considering the lack of significant correlation, positive and negative increase according to the different densities Was observed.inTotal distance between rows of different treatments with different seed rates not seen much difference. such a conclusion has been that the distance between rows 20 and 30 cm in lodging resistant varieties for optimum use of land, preservation soil moisture, increase efficiency, reduce pollution the rot charcoal and to overcome the weed was effective
