Effect of Integrated Use of Nano and Non-Nano Fertilizers on Yield and Yield Attributes of Wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted at AL-Husseiniya, Babylon Governorate to study the effects of nano-NPK application, micro fertilizer and yeast extract of Saccharomyces cerevisiae on growth and yield of wheat cultivar Adana 99. The experiment included 8 treatments with of Nano-chelated NPK 20-20-20 fertilizer (NNPK), Nano Complete Micro fertilizer (NCM), Yeast Extract of Saccharomyces cerevisiae (YE), two-component mixtures of nano-fertilizers and Yeast Extract (YE+NCM), (YE+NNPK), (NCM+NNPK), tri-component mixture (YE+ NCM+NNPK) and untreated control variant. The experiment was conducted according to RCBD design. The results showed that treatment with YE, NCM and NNPK followed by the combined spraying of di-(YE+NCM), (YE+NNPK), (NCM+NNPK) and tri-component fertilizers (YE+NCM+NNPK), respectively can increase the wheat growth and yield. The harvest index was in the range (from 35.31 to 45.58%) for control. The highest agronomic productivity was achieved with significant superiority when using foliar spraying of single nano-NPK and mixture of nano-fertilizers (NNPK+NCM) i.e., 616.33Mg h-1 and 509.00kg kg-1, respectively.
