To evaluate fourteen local Egyptian genotypes of onion (Allium cepa, L.) under calcareous soils and drip irrigation for increasing economic income by through cultivation of the high yielding onion genotypes (cvs) and found the high quality cultivars in export characters. In this respect, two filed experiments were conducted at Experimental Farm of Nubaria Agricultural Research Station during 2014/2015 and 2015/2016 winter seasons in randomized complete block design (RCBD) with 5 replications. The obtained results cleared that there were a significant difference among the 14 onion genotypes in all studied characters. Whereas, the combined analysis of variance revealed significant differences among the fourteen genotypes for all studied characters. It can be concluded that Composite 16 large oblong genotype recoded the highest total and market yield of onion under calcareous soils under drip irrigation in Nubaria Region to increase economic income.
