Impact of Foliar and NPK Fertilization Treatments on Bread Wheat Productivity and Quality

Abstract

Two field experiments were conducted to study the effect of foliar and NPK fertilization on productivity and grains quality of wheat Misr 1 cultivar during 2014/2015 and 2015/2016 seasons at a private field in Dekernis Center, Dakahlia Governorate, Egypt. The experiments were carried out in a strip-plot design with four replicates. The vertical plots were assigned to six foliar treatments i.e. without, spraying with; commercial NPK as Ferti-plus powder (20-20-20), solution of micro-elements (Zn, Mn and Fe), amino acids in the form of Amino-Cat, yeast extract (YE) and the mixture of commercial NPK, micro-elements, amino acids and yeast extract. The horizontal plots were allocated to three levels of NPK fertilizers (60, 80 and 100 % of the recommended doses i.e. 80 kg N + 45.0 kg P2O5 + 48.0 K2O/fed). The foliar spraying twice with the combination of commercial NPK, -elements, amino acids and yeast extract produced the highest values of all studied characters in both seasons, Followed by foliar spraying wheat plants twice with yeast extract (YE) (100 ml/Liter water) in each spraying. Fertilizing with 80 + 45.0 + 48.0 kg N, P2O5 and K2O/fed gave the maximum values of all studied characters during both seasons. Mineral fertilizing with 64.0 + 36.0 + 38.4 kg N, P2O5 and K2O/fed/fed ranked secondly after the highest level of NPK fertilization. It can be accomplished that foliar spraying wheat Misr 1 cultivar twice with the combination of commercial NPK, micro-elements, amino acids and yeast extract beside mineral fertilizing with 64.0 + 36.0 + 38.4 kg N, P2O5 and K2O/fed/fed under the environmental conditions of Dekernis Center, Dakahlia Governorate, Egypt in order to maintain high productivity and grains quality at the same time reduce production costs and environmental pollution.
