THE EFFECTS OF CLINOPTILOLITE APLICATION ON GROWTH AND NUTRIENT IONS CONTENT IN RICE GRAIN

Abstract

The experiment was carried out at the experimental fields of the Field Crops Department, Faculty of Agriculture, Ege University during the growth period of 2003 and 2004. Split-plots experiment design with three replications were used. The main plots were clinoptilolite applications (with 6 t ha -1 and without treatment) and the sub[1]plots were rice varieties. Average yield of the varieties was approximately 11 % higher in the first plots with clinoptilolite application than untreated plots (the second plots without clinoptilolite). It was observed that clinoptilolite affected yield components positively. It decreased sterility (9.3 %) on the other hand, increased protein content (9.7 %) and macro-micro mineral in grain.
