Effect of magnetic water, foliar application with nano material and nitrogen levels on productivity and quality of head lettuce

Abstract

Two field experiments were carried out at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Egypt, during seasons of 2015/2016 and 2016/2017 to study the effect of magnetic water irrigation (normal water and magnetic water), foliar spraying with nano material water as well as their interactions on growth, yield and quality of head lettuce (Big bell cultivar). The experiment was carried out in a strip-split plot design with three replications. The vertical-plots were allocated for water irrigation treatments. The horizontal plots were devoted for foliar spraying with and without lithovit at the rate of 0.5 g/liter. The sub-plots were included N-levels (100, 75 and 50 % N of the recommended doses). The obtained results could be summarized as follows:
