Abstract: The field experiment was conducted at College of agriculture, Bijapur, to know the effect of crop geometry on pearl millet under dryland conditions during Kharif 2013-2014. The experiment was laid out with eight treatments replicated three times in randomized block design. Row spacing of 120 cm x 5 cm recorded significantly higher pearlmillet grain yield as compared to recommended spacing 60 cm x 10 cm (1203 kg ha^-1). The increase in grain yield was to the tune of 60 percent higher with 120 cm x 5.0 cm. Row spacing 135 cm x 10 cm recorded significantly higher absolute growth rate and relative growth rate 0.94, 2.96 and 16.73, 50.21 at 30 to 60 DAS and at 60 DAS to harvest respectively. As the row spacing increases net assimilation rate was also increased, highest net assimilation rate was found in the treatment 135 cm x 10 cm (0.25 g dm^-2day^-1 and 11.07 g dm^-2day^-1) at 30 to 60 DAS and 60 DAS to harvest respectively.
