Field experment was carried out to study the effect of seed size(: small 100seeds 7.56
mm
3 and large 100seeds 20mm3),irrigation(forth levels : 3 , 6 , 9 , 12 days period) and
nitrogen fertilization ( 0 , 5 , 10 , 15 kgN/d). Experment set up in Black plastic Plots(9kgs
capacities). The design of the experment was RCBD in split-split sub plot arragment in three
replications ,seeds were sown at stayer pore in 20 gm peatmoss at 1/9/2013, and seeding
trnsfer in to plots at 1/10 , sample of soil was took befor planting for analyzed to determine
physical & chemical properties ,dry seeds were taken 4 month after planting for analyzed to
showed grain yield, percentage of nitrogen , carbohydrate, protien, oil, proline and trigoline
alkloide. Results indicated all facters and interactions were signifcant effects and incresed
grain yield, percentages of carbohydrate, and oil at interaction of large seeds size and every 3
days irrigation and 5kgN/d , while max percentages of nitrogen , protein , proline and
trigoline at interaction of small seeds size and 12 days irrigation and 5kgN/d. |
