diammonium phosphate time of durum fertilizationAbstract
Two field experients were conducted EL- Mokhtaar university at EL—Bayda during the growing seasons 2015- 16 and 2016- 17 to
Study the response of durum wheat (Marjawii) cultivar to fertilization time at seeding , at tillering stage comparing to control. Seeding by drilling in the rate 110 kg ha -1 and fertilization by hand by the rate 250kg ha-1 . The experiments layed out in RCBD design by 4 replicates each having 3units with an area 4× 1.5 (6m)2
Results revealed significant different (P<0.01 ) in number and weight of spike grains due to during seeding time significant increase (p< 0.05 ) of 1000- grain weight in 2 nd season only and no affect of harvest index in both seasons by time of fertilization , significant increase (p< 0.01 ) of biological yield 4.53 , 4.68 and Straw yield 3.61 , 3.75 t ha -1 due to at seeding time .
Although grain yield recorded 0.92 , 0.93 t ha -1during seeding time mean while not neach significant level . Dunning tillering time gave the significant increase of protein content 12.81 , 12.85 % in both seasons res pectiuey : In conclusion the best date for addition DAP fertilizer for durum wheat in albayda during seeding datee.
