Abstract :

This study was done to evaluate the effect of percent of wind sand (20,40,50,60) combined with farm soil on weight gain of the corms of Crocus sativus as well as its flowering yield in a field located at Gheshlagh village of Moin Abad of Varamin in 2010-2011. The experiment contained five treatments and was performed at a complete randomized block design with four replications. The corms were planted linearly in each row at the depth of 20cm and the distance of 7cm from each side. Irrigation was done in three times of 2010 October 7, 2010 November 6 and 2011 march 28 and the rows provided. Leaf pod and flowers present at each row were counted on a daily basis and the number was recorded daily. Average growth of the corms in each row shows significant difference p <%1. Results showed that treatments containing %40, %50 and %60, wind sand had a significant effect on average growth of the corms of Crocus sativus where treatment containing wind sand of 20% and farm soil of 80% had less effect. Field soil of Varamin showed the least effect on corm growth. Addition of 60% and 50% wind sand is recommended for the fields of Varamin region regarding culture of Crocus sativus.
