sugar beet, boron, spraying time and newly reclaimed soil |
| |
Experimental work was done in Al-Wady El-Assiuty, Expt. Farm of Assiut University, Assiut, Egypt during 2010/2011 and 2011/2012 seasons to investigate the effect of boron concentration (zero, 50 and 100 ppm) and different applica-tion time (35, 70 and 105 days after planting, DAP) on yield and quality traits of sugar beet plant grown in newly reclaimed soil conditions. Randomized complete block design (RCBD) using split-plot with three replications was used. The ob-tained results revealed that:
-Yield and quality traits of sugar beet i.e., top and root fresh and dry weights, sucrose %, sugar recovery % and K concentration in root were signifi-cantly increased by high boron concentration compared with control in both sea-sons.
-Boron spraying time had a significantly positive effect on yield and quality traits of sugar beet, however it’s had any considerable effect on tops dry weight (ton fed.-1), sugar loss %, sugar loss yield (ton fed.-1) and some impurities com-ponents concentration in both seasons.
-There were significantly effects due to the interaction between concentra-tion and spray time of boron on yield and quality traits of sugar beet crop except for sugar loss %, sugar loss yield (ton fed.-1), ?-amino-N and Na concentration of root in both seasons.
It could be concluded that the highest sugar yield and the best technological quality of sugar beet were obtaining by using 100 ppm boron concentration and spraying after 70 days after planting under newly reclaimed soil conditions. |
