Abstract :
The application of zinc and silicon elements improves the growth, yield and nutritional value of seeds. The use of organic fertilizer can help to improve the yield and nutritional value of seeds by improving the availability of nutrients. This study was conducted with the aim of improving the quantity and quality of wheat grain in the Faculty of Agriculture of Qaemshahr Islamic Azad University (Mazandaran-Northern Iran) during the years 2018-2019 and 2019-2020. The experiment was carried out as a split plot based on a randomized complete block design with 3 replications. Experimental treatments included animal manure with 2 levels (cow manure and no-consumption) as the main factor and the application of zinc and silicon elements (nano and normal fertilizers) with 9 levels as secondary factors. The results showed that the effect of year was not significant on any of the traits studied. The grain yield in the treatment without the use of cow manure was 16% higher compared to the use of cow manure, which was due to the increase in the numbers of spikelets and seeds in the spike. The highest grain yield was obtained for the treatment without using cow manure and with the use of zinc sulfate and the simultaneous use of potassium silicate and zinc nano oxide (4394 and 4423 kg/ha, respectively). The highest concentration of zinc in seeds was obtained by foliar spraying of zinc nano oxide, potassium silicate + zinc nano oxide, and silicon and zinc nanoparticles. The maximum seed protein was obtained in the treatment of cow manure application along with foliar spraying of zinc nano oxide, silicon and zinc nanoparticles, and soil application of zinc sulfate. The use of zinc sulfate alone or the combined use of potassium silicate + zinc nanooxide is suggested to improve grain yield. The use of cow manure combined with each of the treatments of zinc sulfate, zinc nanooxide, and silicon + zinc nanoparticles is recommended to increase seed protein.
