Abstract

 
Two field trials were conducted at Shandaweel, Agric, Res. Station, A.~.E"
during the growing seasons 2000 and 2001 the work aimed to evaluate the eHect of
diHerent applications of phosphorus (0, 22.5 and 45 kg P205/fed.) and sUlphur
treatments (0, 30, 60 and 90 kg S/fed.) on yield, nodulation, plant growth, N%, protein
content and P% of Lupine (Lupinus Term/s L.) variety, Giza 2 , A SlJlit plot design with
four replicates was used, P fertilizers in the main plots and sulphur treatments i the
sub-p'ors.
 
The obtained data indicated that increasing either P or S rates had a
significant effect on yield and its components, The interaction affect of both facto s (P
and S) was significant on seeds yield, plant growth measurements, nodulation intensity,
nitrogen %, protein content and phosphorus %, Combination effect of phosphorus and
sulphur applicalions
