Influence of Sulphur and Boron Levels on Productivity and Quality of Sugar Beet under Sandy Soil Conditions

Abstract

Two field trial were fulfillment at Kalabsho Experimental Farm (sandy soil) located at the longitude of 31.220 E and latitude of 31.140 N and 15 m above sea level in seasons of 2012/2013 and 2013/2014 to find out the influence levels of sulphur and boron fertilizers on sugar beet cv. Gloria yields and quality traits. A strip-plot by way of three replicates was done through together seasons. Sulphur fertilizer levels (50 , 100 and 150 kg S/fed) were added to the soil in the vertical-plots. While, levels of boron fertilizer (without, 5 and 10 %) as foliar application were devoted in the horizontal-plots. The obtained results showed that, in both seasons, fertilizing with 150 kg S/fed for sugar beet plants produced the greatest yields and its components and quality traits, followed by fertilizing with 100 kg S/fed and lastly fertilizing with 50 kg S/fed. Spraying sugar beet plants with solution of 10 % boron resulted in the maximum yields and its components and quality traits. Spraying sugar beet plants twice with boron (5 %) ranked secondly after boron (10 %) and followed by control treatment (without spraying plants with boron) through together seasons. It might be accomplished that fertilizing sugar beet plants through 150 kg S/fed and sprayed twice (after 50 and 70 days after sowing) with solution of 10% boron to maximizing yields and juice quality under the environmental conditions of sandy soil in Kalabsho region, Dakahlia Governorate, Egypt.
