Pots experiment was conducted in the green house of Biology
department , College of Education ( Ibn Al-Haithum), University of
Baghdad , growing season of 2009,to study three levels of Diamonium
phosphate fertllizer (0,0.16,0.32) eml2Kepot this equal (0,40,80) Kg/d.
respectively , three concentrations of gibberllin (0,50,100) ppm and
their interaction on elements concentration (N,P,K and Ca ) and protein
percentage in vegetative part of lentll (I*ns culinaris Medic. ) cv.
Barka.
Factorial experiment with completely randomized design with
three replications was adopted .
Results showed that fertilization of phosphate at different levels
and concentrations ofgibberllin spray increased and significantly
influenced element concentrations and protein percentage except the
phosphorus concentration .
Also, results showed that fertilization of phosphate and gibberllin
spray has significant effect on N,K and protein percentage
concentration but not significant effect on P and Ca concentration ,
since treatment with (80Kg/d. fertilizer and 50ppm gibberllin )gave the
highest concentration of N and protein percentage , while treatment
with (80Kg/d. fertilizer and l00ppm gibberllin ) gave highest
concentration of K. |
