Abstract

The use of magnetizers for the treatment of irrigation water can be used in agriculture as an alternative to increase the growth and yield of several crops. The objective of this study was to evaluate the effect of different irrigation depths and magnetic treatment of water on eggplant crop cultivated in protected environment. The study was carried out in two experiments, in the first one, the design was completely randomized with four replications and two factors: water depths (50, 75 and 100% ETc) for two water qualities (water treated by magnetizers and water without treatment). In the second one, the design was completely randomized with five replicates and two factors: water depths (75 and 100% ETc) for two irrigation water treatment (water treated by magnetizers and water without treatment). In the second experiment was ignored the treatment of 50% of ETc in order to increase the number of repetitions to check if there are differences between water treated to water without treatment. There were no significant differences in eggplant yield and growth as function of the magnetic treatment of water. The water depth that provided the highest yield, number of fruits per plant and stem dry matter in the two experiments was 100% ETc regardless of water quality.

Highlights

Due to several reasons, water sources are facing challenges and studies are required for sustainability of agricultural crops (Surendran, Sandeep, & Joseph, 2016).Eggplant (Solanum Melongena L.) belongs to the Solanaceae family as well as tomato and bell pepper having similar requirements (Díaz-Pérez & Eaton, 2015)
This study aimed to evaluate the response of yield and growth eggplant crop, cv
According to the analysis of variance there were no significant differences for the variables evaluated as a function of irrigation water treatment in the Experiment I (Table 1)

Summary

Introduction

Water sources are facing challenges and studies are required for sustainability of agricultural crops (Surendran, Sandeep, & Joseph, 2016).Eggplant (Solanum Melongena L.) belongs to the Solanaceae family as well as tomato and bell pepper having similar requirements (Díaz-Pérez & Eaton, 2015). Water sources are facing challenges and studies are required for sustainability of agricultural crops (Surendran, Sandeep, & Joseph, 2016). Surendran, Sandeep, and Joseph (2016) applied magnetic treatment of water in eggplant cultivation and obtained increasing on plant height, number of leaves, leaf area and individual fruit weight, and especially increase in yield of 25.8 and 17.0% under normal conditions and water saline, respectively. In a study with different replacement levels and different magnetic flux densities (control, 50, 100 and 200 mT) in irrigation water for corn crop were observed that magnetization was viable to increase grain yield, regardless of the magnetic flux density that was applied (Fattah & Aoda, 2008). Studies with eggplant plants indicated that this crop can be grown under water deficit (Kirnak, Tas, Kaya, & Higgs, 2002; Aujla, Thind, & Buttar, 2007; Gaveh, Timpo, Agodzo, & Shin, 2011; Karam et al, 2011).
