| Abstract | ||
| A filed experiment was conducted to study the effect of flood and sprinkler irrigation on some Elements losses (N,P , K, Ca,Mg, SO4) from soil and availability of N, P, K in soil , growth and product of corn in plots of 150m area . Planted with corn and fertitized with NPK fertilizer The experiment was conducted with two treatment ; Sprinkler irrigation and flood irrigation . Ramdomize complete block design with three replication was used . Irrigation applied was Up to field capacity and when 55% of available water was lost. Results showed asignificant increase in nutrient elements losses with flood irrigation in comparison with sprinkler irrigation . The lost of these elements in both treatments was at following order : Ca> Mg> N> K> SO4>P. Results also revealed a significant increase of availability of N, P , K in sprinkler irrigation in comparison with flood irrigation . The sprinkler irrigation producted more dry weight and production of corn more than flood irrigation . irrigation producted more dry weight and production of corn more than flood irrigation | ||
