Abstract

Two field experiments were carried out in a sandy soil at ElQureen, Sharkia Governorate Egypt during 2009/2010 and
2010/2011 seasons to study the response of some multigerm sugar
beet varieties i.e., Top, Sultan and Kawemira to foliar spray at 60 and
75 days from sowing with
three levels of compost tea (0.0, 1.5 and 2
L/fed/300 L water). The experimental treatments were allocated in a
split plot manner with four replications.
The
obtained results showed that foliar spraying with compost tea
at the level of 2.0 L/fed significantly increased root length, diameter,
fresh weight/plant, sucrose%, purity%, root and sugar yields/fed in
both seasons. While, it decreased root mineral contents (N, Na and
K%) as compared with zero treatment (control) or 1.5 L/fed level of
compost tea.
Sugar beet varieties significantly differed for root length,
diameter, fresh weight/plant, sucrose%, purity% and root and sugar
yields/fed, root mineral contents. Kawemira variety surpassed the
other two varieties Sultan and Top in most
studied traits in both
seasons.
The interaction between foliar spray
ing with compost tea the at
level
of 2.0 L/fed and Kawemira variety recorded the highest values
for sucrose%, root and sugar yields/fed in both seasons. Generally, it
could be recommended that sown Kawemira, Sultan and Top < br />varieties, respectively, sprayed with 2.0 L/fed compost tea to obtain
the highest sucrose%, root and sugar yields/fed and yield quality in a
sandy soil at El-Qureen, Sharkia Governorate.
