AbstractA field study was conducted during Autumn season 1999 and Spring season 2000 at experimental farm department of Field Crop Science, College of Agriculture, Abu-Ghraib.Univ. of Baghdad.
The aim of the study was to investigate performance of Genotypes of maize (Bohoth 106 and IBA 3001) to difference densities with different spaces (80 cm 20 cm,100 cm 16cm , 40 cm 40 cm, 80 cm 30 cm, 80 cm 15 cm and 80 cm 10 cm) The experiment was laid out in randomized complete block design (RCBD) with three replications.
The results obtained could be summarized as following:
The lower density (80 cm 30 cm) gave the highest value of number grain of ear (668.4 and 735 .4 grain) , weight of single grain (261.6 , 223.9 mg) and yield of plant (120.1 and 87.0 gm) respectively in Autumn and Spring while treatment of highest density (80 cm 10 cm) gave high value of yield grain (9.40 5.4 ton.ha-1) respectively at both seasons.
Iba 3001 under density 62500 plant.ha-1 (80 cm 20 cm) gave high value of grain yield 11.1 and 5.2 ton.ha-1 respectively in both seasons.
