Abstract

Drought is one of the most important environmental stresses that can impair plant growth and crop production.  The purpose of Resent paper is to determine the effects of drought stress and Buried by sandon yield, yield components of canola (Brassica napusL.) as well as soil properties. The research was investigated in crop year 2013-14 in the field of Educational Research Institute of University of Zabol. Experiment split-plot in randomized complete block design with three replications. The main plot was drought stress in three levels including; 50, 100 and 150 mm evaporation from evaporation pan and sand buried quantities was considered as the sub – plot in three levels; control, 100 and 200 t/ha. The highest of grain yield (460.87 kg/ha) was obtained from treatment 200 t/hadue to Buried by sand. The result shownthat yield was increased in comparison to the control treatment of about 29.61 percent. The maximum soil temperature shows in treatments of 100mm and 150 mm respectively 27/5cº and 28/3cº evaporation from pan evaporation and the lowest soil temperatures in 50 mm from pan evaporation treatment was obtained 25/3c° .Using sand storm, the soil temperature decreased and the highest soil temperature (28/2c°) was observed in control treatment. The interaction of drought stress and sand storm showed that the highest grain yield in drought stress 50 mm evaporation and the application of sand storm 200 t/ha. This was indicates that the positive effect of sand to reduce evaporation.
