Abstract

Abstract: A field experiment was conducted during the 2022 agricultural summer season, at one of the fields of Jamajon Desouk, Kafr El-Sheikh Governorate, to study the response of the maize (Zea mays L,) to add three levels of seaweed fertilizer 0, 1 and 2 kg ha-1, four levels of nano- macronutrients were 0, 15, 25 and 50% of recommended doses from N, P and K The Field experiment was split plot design with three replicates Total plot area 10.5 m2 (Each plot consisted of 4 lines 3 - meter width and 3.5 m were used for to estimating yield and yield components at harvesting. Results from this study demonstrated a considerable advantage of the SW2 seaweed fertilizer treatment over the comparison treatment for all growth and yield characteristics, followed by the treatment with NF2 macronutrients. The combination (SW2 + NF2) generated the most significant improvement in the characteristic of dry weight, yield of grains, and the highest values for (NPK) concentrations in the straw and grain because of the binary interaction between fertilizing seaweed and nano-macro nutrients.
Keywords:: Seaweed, macronutrients, nano-fertilisers, maize.
