The aim of the study was to investigate the response of summer squash cultivar, namely (Alexanderia&nbsp; F1) to four levels of organic &nbsp;(0 , 2 g.L<sup>-1</sup> Fulvic acid, 2 g.L<sup>-1</sup> Seaweed extract and 4 g.L<sup>-1</sup> Amino acid&nbsp; ) and three level of inorganic fertilizers ( 0, 1 ml.L<sup>-1</sup> Cal-Mag and 5 ml.L<sup>-1</sup> Phosphate-K) on growth and yield of summer squash plant (<em>Cucurbita pepo</em> L.). Fertilizers were used three times at the 25 days of planting and repeated in 10 days interval. Results showed that Spraying Summer squash with organic fertilizers especially amino acid significantly increased characters like (chlorophyll content in leaves, No. of fruit f.plant<sup>-1</sup>, plant yield kg.plant<sup>-1</sup> and total yield t.ha<sup>-1</sup>), Also inorganic fertilizers especially Cal-Mag had higher increased&nbsp; in characters ( plant length, leave area, chlorophyll content in leaves, No. of fruit f.plant<sup>-1</sup>, plant yield kg.plant<sup>-1</sup> and total yield t.ha-1), where as no significant differences occurred in (Fruit length (cm), Fruit Diameter (cm) and TSS) by using organic and inorganic fertilizers</strong></p&gt;}, number={1}, journal={Journal of Duhok University}, author={SHAREEF, REZAN SAEED and RASHEED, SANAA M.S. and ZEEBAREE, PASHTIWAN J.M.}, year={2022}, month={May}, pages={17-25} }
