Effect of nano and/or normal fertilizers on growth and productivity of some potato cultivars grown in the Middle Egypt.

Abstract

Nano fertilizers are the talk of recent years in agriculture as farmers are asking for the impact
of these fertilizers on production and quality of the products of several crops. In this research we
studied the effect of NPK, zinc and boron in the nano and/or normal forms on growth and yield of
three cooking and processing potato cultivars (Burren, Cara and Lady Rosetta) under the Middle
Egypt (Minia) growing conditions in two successive winter seasons of 2023 and 2024. Results
revealed that there were significant differences among the three used cultivars and mixes of nano
and/or normal forms of macro and micro elements showed several effects of potato plants growth
and tubers productivity. When combinations of different fertilizers and mixes were used the
potato plants growth and yield were improved but the best mixes were the combination of 50% or
75 % of the recommended normal-NPK dose + Nano-NPK (foliar application) + Nanomicronutrients (Zn and B) which gave all high values of the desirable characteristics e.g., plant
fresh and dry weights, single tuber fresh weight and yield of tubers / feddan. These mixes could
be recommended to potato farmers of the Middle Egypt and similar growing conditions to
increase their income from potato plantation and reduce potato cultivation costs.
