Effect of atrazine as sublethal and zinc as well as boron on some parameters of sugar beet [electronic resource].

Includes reference.

Results indicated that, the atrazine treatments as sublethal concentrations gave erratic effect during the two experimental season. During the first season spraying sugar beet by atrazine at the rate of 100 ppm led to an increase on top dry weight/plant, root diameter, root yield/fed., sucrose percentage, sugar yield /fed., as well as N and K % in juice. Some of the above mentioned characteristics did not take the same direction under the effect of the same application during the second season. B application increased top and plant dry weight and some yield components up to 50 ppm. On the contrary, sucrose percentage and sugar yield were reduced. Spraying sugar beet plants with Zn at 1500ppm increased significantly top dry weight, dry weight/plant, root yield and sugar yield/fed, whereas sucrose% and sodium % were reduced. Most of the first and second order interactions had significant influence on the above traits under study.
