| Abstract | ||
| A field experiment was carried out at the center of training agricultural Al-mahanawia Babil during spring and autumn seasons of 2014 to study the effect of the plant density and ethyphon concentration in growth and grians yield of corn soil The experiment was done with factorial experiment arrangement by ( RCBD) the first factor was agriculture density between the rows ( 40 , 55 ,70)cm . The second factor was the concentrations' of ethyphon (0 - 280-420 - 560 ) gram/he . The results reveeled a significant differences among the plant density and ethyphon concentration for all study traits the density between rows (70)cm by giving high value for leaf area (0.317,0.460)m2 and at 500 grain weigh (136.39,161,72)g for both seasons spring and autumn respectively .while the number of grain /ear trait the density between the rows (55)was succeeded by giving high rang (579)grain/ear for spring season .in other hand the density between rows (40)cm was succeeded by giving high rang (645) grain /ear at autumn season. but the density between rows (70)cm was succeeded at the grain yield trait(263.26,267.10)g for both season spring and autumn sequentially .when the protein ratio ,the same density between rows was succeeded by giving a high rang (9.33,10.12)%for both season spring and autumn sequentially. while the level of ethyphon (0)g/he level gave high ranges for the flowing traits:-leaf area,500 grain weight,number of grain/ear,grain yield, protein ratio of grains. (0.390,0.426)m2,(138,67,163.14)g , (571.60,640.0) grain/ear (260.09,266.50)g and(9.0,9.88)%for both season spring and autumn sequentially.the interference between the density and the ethyphon levels was significant for traits:leaf area,500 grain weight,grain yield,but the difference were no significant for both traits:number of grains/ear and protien ratio in grains. | ||
