Abstract

In order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. Growth parameters such as Leaf Area Index, Crop Growth Rate, Total Dry Weight and Relative Growth Rat were analysed. PH and EC of the soil at 0-30 and 30-60 cm depth were 8.7, and 17, respectively. Five seed sowing methods were : sowing in the middle of row using manure as fertilizer, sowing on the edge of each row, sowing on middle of row after irrigation and removing surface soil, sowing on both sides of each row and sowing along the furrow . Simple and combined analysis of variance were made and means of treatments as well as interaction means of cultivar x treatments were grouped. The results demonstrated significant differences between root yield, white sugar yield, growth parameters and Na / K ration for two progeny lines and sowing methods.
Maximum leaf area index and root yield were 2.27 and 27.02 (t/h) respectively when seeds were sown in one side of the row. In this sowing method the Na/K ratio of two progeny lines was less than in other methods.
