- The aim of the study was to find out recommendable row spacing (17.5 - 35 cm) and seed rates (15, 25, 35, 45, 55 and 100 seed/m2) for three chickpea genotypes which have different growing types (erect type AK-71114, semi erect Akçin -91 and prostrate ILC-86172) and adapted to Central Anatolia.

The study was conducted during the years of 1994-97 as field trials in Haymana, TARM Research Farm. Experimental design was randomized complete block in split plots with three replications.

Results indicated that there was no statistical differences between row spacing in two genotypes (AK-71114 and ILC-86172). On the other hand wider row spacing (35 cm) had better yield than narrow row spacing (17.5 cm) in Akçin-91 variety. Wider row spacing (35 cm) is very suitable for mechanical weeding than narrower row spacing (17.5 cm).

Seed rates have been found statistically different in all years and genotypes. Although physical optimum point of the regression analyses have been given higher seed rates. 45 seed/m2 has been found economical for all genotypes.

Although these characters are mostly controlled genotypically, seed rates also played an important role on them. Significant impact of seed rates on plant and first pod heights were determined in this study. Linear positive correlation was detected with seed rates and heights of plant and first pod. Keywords :
