RESPONSE OF SOME INDICATORS OF VEGETATIVE AND SEED GROWTH OF THE FIRST-GENERATION HYBRID OF GYNOECIOUS CUCUMBERS FOR PROTECTED CULTIVATION TO THE DATE OF HARVEST, THE DATE OF SEED EXTRACTING AND NUTRIENT SPRAYING

The experiment was carried out in one of the greenhouses Department Horticulture and Landscaping / College Agriculture University Anbar. With an area ​​500 m2 during autumn season 2021, two locally derived strains were pollinated a sexual modification process performed on them to produce male flowers it is considered pollinator for other strain. study included six dates harvesting seed extraction, fruits after 45, 50 55 days hybridization direct extraction seeds, symbolized by T1, T3 T5 sequentially, extracting seeds 5 harvest T2, T4 T6 sequentially. spraying with three concentrations BREXIL DUO 0, 1.5 3 gm. l-1 S0, S1 S2 collected their extracted according dates. date led increase stem diameter field emergence dry weight seedlings if they gave values ​​of 2.288 mm 47.464 mg Treatment showed superiority In characteristics vegetative growth at concentration g l-1, which amounted 2.151 47.870 respectively, addition specifications represented percentage germination, speed average yield experimental unit that harvested Extraction 99.000, 98.222 (%), 4.479, 5.266 (seed day-1), 3.416, 3.301 (gm. fruit-1), 170.700 165 .094 (g) respectively
