Abstract
Abstract The study was conducted at the Basrah University / Karmat Ali, Iraq during the fall season 2020, to investigate the effects of four rates of phosphorus,(P0 =0, P1=40, P2=80 and P4=120 kg P ha -1 ) and spraying four concentrations of zinc (Zn0-control, Zn1= 25, Zn2=50, Zn=75mgL -1 on growth and forage yield of Sudangrass. The randomized complete block design (RCBD) was carried out in three replicates using a split plot experiment, zinc concentrations were put in the main plots while, rates of phosphorus in subplots. Application with P 120 resulted to a significantly greater stem diameter (14.61mm) number of leaves (20.00 leaf plant -1 ), leaf area (7420cm 2 ), number of branches (14.967 branch plant -1 ) green and dry forage yield (29.25,12.69 t ha -1 ). Foliar application of Zn 75 resulted in greater plant height (251.2cm), stem diameter (14.21mm), number of leaves (19.42 leaf plant -1 ), leaf area (6163cm 2 ) and number of branches (13.450 branch plant -1 ). The combination of P× Zn had no significant effect on green and forage yield. Both P and Zn application had significant effect on N and P percentage of forage Sudangrass, on the other hand, no significant effect of their application on K percentage.
