The objective of the study was to investigate response of growth of Genotypes of maize (Bohoth 106, IPA 3001) to densities with different spaces (80 cm  20 cm, 100 cm  16 cm ,40 cm  40 cm , 80 cm 10 cm, 80 cm 15 cm and 80 cm  30 cm).
The experiment was laid out in randomized complete block design (RCBD) with three replications.
The result obtained could summarized as following:
All treatments caused significant effect on all studied characteristics. The density (125000 plant .ha-1) which planted with spaces 80 cm  10 cm gave the highest value of leaf area index (5.40, 5.90), weight of dry matter (19.76, 30.29 t. ha-1) respectively in Autumn and Summer seasons. There fore we get high crop growth rate (32.69, 60.52) respectively in both seasons then other treatments.
Genotype bohoth 106 gave high value of leaf area index (3.59, 4.69) respectively in Autumn and Spring seasons.
The interaction between genotypes and spacing was significant. The genotypes bohoth with space 80 cm  10 cm gave high value in weight dry matter (20.41, 31.30) and crop growth rate (37.70, 68.21 gm. m-2. day-1) in both seasons.
