Abstract
In order to increase the sunflower outputs, science and technology search for efficient and relatively inexpensive mineral feeding. This study investigated the effect of natural zeolites and their combinations with phosphorus mineral fertilizers on growth and biological yield of sunflower varieties Fortimi and Zarya. A two-year field trial using a a randomized complete block (RCB) with three repetitions and eight treatments was conducted in the Uspensky district, Pavlodar region, Kazakhstan.  tried to determine the effect of zeolite on the yield of seeds and the yields of sunflower. Considering variable climate conditions, introduction of natural zeolite in soil improved growth of plant biomass (taller plants), leaf area and photosynthetic potential and produced high yields compared to control (no fertilizer) variants. For instance, inspite of low germination rate (i.e. in 2016) variety Zarya showed high and stable yields, i.e. 3,00 to 3,55 t/ha after treatment with 3 and 5 t/ha zeolite and all combinations of zeolite with superphosphate.
