Abstract

This experiment was carried out in the plastic house (500m²) at protected cultivation department in Zakho technical institute/Dohuk polytechnic university., during growing seasons (2021-2022), to investigate the effect of sowing date (15 August, 1 September & 15 September), bio fertilizer (0, 2ml.L^-1) & nano fertilizer (0, 3, 6 & 9ml.L^-1) on Cauliflower (Brassica oleracea var. botrytis l.).,The appeared results demonstrated that both planting date on 15-Augustes and Nano fertilizer at concentration (9.ml L^-1) had significant differences in terms of vegetative growth characters, All studied parameters in the vegetative and macro nutrient contents were significantly increased by the first planting date during the study seasons. It was also observed that treating plant with Bio fertilizer at 2.ml L^-1significantly increased all investigated traits. The interactions between planting date at 15- August and Nano fertilizers (9 ml.L^-1) were noticeable appeared by the improving of most detected traits. Significantly impacted most measures, whereas high concentration of Nano fertilizer and first planting date together produced the greatest overall result in all vegetative growth parameters (Number of leaf. leaf area (cm²), and chlorophyll contents (SPAD). Re there was an increase grading nutrients contents, significant enhancement were showed
