“The interaction between nitrogen fertilizer (400kg/ha) and Organic fertilizer (18ton/ha) scored high significant percentage compared with control treatment, for Abu-Ghraib variety was: No. of grains/spike (136%), total grain yield gm/pot (246%), total weight of 1000grains (75%), protein in grain (232%) and starch (33 %). While for Ibaa variety was: 142%, 240%, 89%, 248% and 38% respectively.”
