Effects of different fertilizer treatments on grain yield and yield components of spring wheat

The present research was carried out to investigate the effects of different fertilizer treatments on grain yield and yield components of spring wheat (Triticum aestivum L.) 'Harenda' cultivar.The five treatments were as follows: control (standard NPK fertilization), standard NPK fertilization plus liquid NPK (10-11-11) fertilizer, standard NPK fertilization plus liquid NPK (10-11-11) fertilizer with microelements, standard NPK fertilization plus calcium micronized suspension fertilizer, and standard NPK fertilization plus Cu, Mn, Zn, Ca micronized suspension fertilizers.The field trials were conducted in 2017 at the Experimental Site of Institute of Soil Science and Plant Cultivation -State Research Institute in Puławy, Poland.Applications of calcium micronized suspension foliar fertilizer and a mixture of Cu, Mn, Zn, Ca micronized suspension fertilizers significantly increased grain yield of spring wheat, respectively by 44.5% and 38.6% in comparison with control (standard NPK fertilization).These fertilizer treatments also enhanced yield components of spring wheat.Moreover, micronized suspension fertilizers (Ca and the mixture of Cu, Mn, Zn, Ca) had a significant effect on ear number and thousand grain weight of spring wheat compared to control and NPK fertilizers.Liquid NPK and micronutrient-enriched NPK fertilizers had a significant effect on thousand grain weight compared to control.
