437 Pb 212 Effect of Soil Fumigation With Methyl Bromide on Mineral Nutrition of Strawberry

Abstract

<jats:p>This study was earned out on strawberry (<jats:italic>Fragana</jats:italic> × <jats:italic>ananassa,</jats:italic> Duch.) during the tow successive season of 1988/1989 and 1989/1990, at the strawberry Improvement Center Experimental Farm at Omm saber, south Tahreer, El Behira Governorate. The objective of this work was to study the effect of strawberry cultivar Douglas A split-plot design with four replicates was adopted. The results indicated a substantial increase in the content of the available macro and micro nutrients in the fumigated soils compared to the non fumigated ones. A significant increase in the number of leaves per plant, fresh and dry weight, early and total yield per plant was recorded. Fumigation accompanied by fertilization increased the available content (N,P and K and (Fe, Mn, Zn, and Cu) in the soil in the both growing seasons compared to fumigated only or the control. Plants grown in the fumigated fertilized plots contained the highest amount of macro and macro nutrients in both the growing seasons. Fumigated non fertilized plots had the highest amount of available P and K than all other treatment The maximum early and total yield per plant was obtained from the fumigated non fertilized plots.</jats:p>

Soil Microbial Community Structure and Target Organisms under Different Fumigation Treatments

“…Also, we observed little change in DOC concentration among different treatments. MeBrPE treatment contained significantly greater Ca and Mg as was observed in the previous study by Ragab and Okasha [41], where they found a considerable increase in the content of macronutrients, especially Ca and Mg, in the fumigated soils compared to the nonfumigated control soil.…”
