t0“SUGAR BEET”
e0“Two field experiments were conducted during 2008/2009 and 2009/2010 seasons at Sakha Research Station, Kafr EL-Shaikh Governorate to study the influence of three nitrogen rates (75, 100 and 125%) of recommended rate (RR=80Kg N/fed)”
e4“increasing N dressing up to 100 Kg N /fed (125% of RR) significantly increased photosynthetic pigments i.e. chlorophyll a,b and carotenoids at the age 120 days from sowing in the two seasons”
e5“Na, K and α- amino N as impurities, sugar loss to molasses (SLM), yields of roots and sugar but juice purity was significantly decreased”
