Effectiveness of Hydrogen Peroxide on Reducing Irrigation Water ‎Quantities, Pests and Enhancing Kohlrabi Production

Abstract

This study was carried out at Faculty of Agricultural - Suez Canal University which located in north eastern Egypt, within the Governorate of Ismailia. The experiment was conducted to assess the influence of hydrogen peroxide on reducing   irrigation water quantities, Mite infestation and kohlrabi Production. Thus; the aim of this study is to monitoring the influence of three treatments hydrogen peroxide (G1, G2 and G3) with average (5mL/plant, 10mL/plant and 0mL/plant [without hydrogen peroxide]) respectively, and three treatments for irrigation water quantity [Q1, Q2 and Q3] with average amount of water (180, 270 and 360mm) respectively on yield production, growth parameters, leaf area index, mites, insects density, and irrigation water uses efficiency. The highest yield value has recorded with Treatment (G1) by (5427.3 Kg.Fed-1). Which is a significant value comparing with other treatment (G2 and G3) which obtained a low value by (3721.7 and 4325.07 Kg.Fed-1) respectively. In addition; the result of irrigation water use efficiency recorded a best value with (G1) by 5.62, 3.25and 4.16(Kg.m^-3) under Q1, Q2 and Q3 respectively. Thus; the irrigation water use efficiency obtains a highest mean value by (4.43 Kg.m^-3) with using hydrogen peroxide treatment (G1). data indicated that there is a significant influence for hydrogen peroxide with (G1) treatment on Euseius scutalis mite which recorded a highest dentistry by (3.78 N/in²) but the lowest value obtained with ( G3) by (1.36 N/in² ). In contrary; there is not any significant impact on Euseius scutalis density with other treatment (Q1 and Q3) which got (2.2 and 2.07 N/in² ) respectively. Moreover; hydrogen peroxide treatments (G1and G2) did not have a significant influence on the other mite ( Amblyseius swirskii) comparing with (G3) treatment. Further; using one doses from (5mL/plant) hydrogen peroxide reducing the density of insects ( Aphis gossypii and Thrips  tabaci) by 50 % comparing with the other value which did not adding a hydrogen peroxide. In addition; the insects increased when reducing the amount of water from 360mm to 270mm by 50% for Aphis gossypii and 75% for Thrips  tabaci.

Keywords: Hydrogen Peroxide, water quantities; mite & insects densities; Irrigation water use efficiency and kohlrabi production.
