THE EFFECT OF SOIL MOISTURE STRESS IN RELATION TON-FERTILIZATION AND ANTITRANSPIRANT APPLICATION ON THE PRODUCTION OF SUGARBEET GROWN IN CALCAREOUS SOILS
AMINA MOHAMED MOHAMED HASSAN;
Abstract
Three field experiments concerning sugar beet plants were conducted in three successive seasons 1995/1996, 1996/1997 and
1997/1998 at soil salinity lab-Agriculture Research Station ofEl-Sabahia. The first experiment was designed to study the effect of nitrogen sources and different rates under different soil moisture stress and their interaction. Nitrogen sources include urea (46% N) and ammonium sulphate (20% N). The applied N-rates of (40, 60, 80 and 120 kg N/fad) of a given sources were used under different available water stress (50-
50/80-80%) using calcareous soil. The outlined experimental design was split split plot design with 3 replicates.
The second experiment was designed to study the effect of different antitranspirant material, different concentrations, number of application and their interaction. The applied concentrations of the tested antitranspirants were as follows:
a. 8-Hydroxy quinoline (a stomatal type) at rates ofzero, 150, 300, 600
ppm).
b. Cycociel (a stomatal type) at rates of zero, 800, 1600, 2400 ppm. c. Plastic emulsion (a film type) at rates of zero, 25, 50, 100 gm/L.
The tested materials were sprayed once after 50 days or twice after
50 and 90 days or three after 50, 90 and 120 days from planting date. The outlined experimental design was split split plot design with three replicates.
