Abstract

The effects of irrigation with magnetically treated water (MTW) and common water (CW) on lettuce plantations at different irrigation depths were analyzed. Current assay was conducted in a greenhouse and featured an experimental 2 x 5 design with randomized blocks and ten replications, comprising two water sources (MTW and CW) and five irrigation depths (replacement of 25, 50, 75, 100 and 125% of evapotranspiration of the crops - ETc). Two crop cycles were undertaken to observe the repeated effects of the treatments. The number of leaves and aerial green weight were underscored among the several effects. An increase in the number of leaves was reported due to irrigation depths in types of water, with a positive effect of MTW at 100% and 125% depths of ET in the two cycles. Increase in the green phytomass of the aerial section was reported when replacement depth of 100% of ET in the two cycles was employed.
