| Abstract | ||
| This study was conducted to reveal the effect of using three sources of phosphorus fertilizer , via , Triple super phosphate ( TSP ) , Ordinary super phosphate ( OSP ) and di ammonium phosphate ( DAP ) , and two method of chelate zinc application , mixing with soil at 25 kg Zn .ha-1 after sowing and foliar application at 5 kg Zn .ha-1 added in three splits ( at eight , fourteenth leaf and Silking stage ) as well as control treatment .120 kg P. ha-1 , 240 kg N. ha-1 and 80 kg K. ha-1 were added for all treatments in RCBD experiment with three replicates. The following results was obtained : 1 – superior of di ammonium phosphate ( DAP) on grain yield ,dry matter weight and weight of 500 grain . 2- superior of foliar method of chelate zinc application , on weight of 500 grain . 3 – The results showed a significant interaction between triple super phosphate ( TSP ) fertilizer and soil method of Zn application in weight of 500 grain, yield of dry matter and plant height .The interaction between ordinary super phosphate ( OSP ) and soil application of zinc was superior in grain yield . 4 – all treated plots were better than control ( 0 P + 0 Zn ) . | ||
