Abstract EN

A field experiment was conducted in spring and autumn season (2014) at farm of one farmer which located in Al-mihanawiyah area (21 Km north Babylon ) prurience 320.31North and longitude 440.21 East in silty clay loam soil to know the effects of three plant density (44444 , 66666 , 133333 plant/h) and four planting methods on ( Row , Furowlng , Raised bed and Furowlng after row planting ) CopletRandomize block design with three replicates was lay out in used as plot spilt arrangement .

the plant density in a sub plot while the planting methods were in a main plots.

growth and grain yield characteristics of Mays hybrid (Al-furat).the highest grain yield was obtained in Spring season (11.55 ton.h-1) compart with autumn season (10.92 ton/h) .

the density (66666 plant/h) gave a highest grain yield (11.99 ton/h) in spring and (11.44 ton/h) in autumn .

the furowlng after row planting method gave a highest grain yield (12.22 ton/h) in spring and (11.91 ton/h) in autumn .

the furowlng after row planting method under density (44444 plant/h) gave a highest grain yield (12.13 ton/h) in spring while the same planting method gave a highest grain yield(12.25 ton/h) under (66666 plant/h) density in autumn.The furowlng after row planting method under density (133333 plant/h) gave a highest plant height (213.70 cm) in spring and (211.00 cm) in autumn , these treatment was a faster in evolution of leaf area The furowlng after row planting method gave a highest plant hight, relative growth rate , crop growth rate and these parameters reflected in increase the the number of ear grain for corn cop (747.59 grain/cob) in spring and (637.40 grain/ear) in autumn and 500 grains weight (182.47 gm) in spring and (205.41 gm) in autumn.
