Abstract
A experiment of field with conducted for the spring season 2018 on summer squash in the fields of the Department of Horticulture and Garden Engineering, College of Agriculture, Al-Anbar University to find out the effect of adding bio fertilizer and spraying with Biozyme as bio fertilizers were added at four levels1-Without adding (comparison) 2- Complete chemical fertilizer recommendation + 50 g poultry fertilizer 3- Half fertilizer recommendation + 50 g poultry fertilizer + 50 g bio fertilizer 4- 50 g poultry fertilizer + 50 g bio fertilizer and Number of times sprayed with the Biozyme it was included 4 levels 1- without spray 2- One time spray 3- Tow times spray 4- Three times spray of. The results showed that all treatments recorded a significant difference compared with control treatments (half fertilizer recommendation + 50 g poultry fertilizer + 50 g bio fertilizer) in all studied traits including leaf content of nitrogen 1.02%, phosphorus 0.47%, potassium 1.79%, iron 225.6 mg kg-1 and zinc 69.50 mg kg-1 , fruit content of Nitrogen 0.98%, phosphorus 0.70% and potassium 0.68% compared to the comparison treatment. Three times the
application of spray Biozyme gave a significant superiority in leaf content of nitrogen 0.98%, phosphorus 0.42%, potassium 1.73%, iron 217.1 mg kg-1 , zinc 64.42 mg kg-1 , and fruit content of nitrogen Phosphorus 0.67%, potassium 0.66% by comparison. As for the interaction between the bio fertilizer and the number of times sprayed with the Biozyme, the treatment (half fertilizer recommendation + 50g poultry manure + 50g wax bio fertilizer three times sprayed with biozyme) gave a significant superiority in all the characteristics of the study, which included leaves content of nitrogen 1.09%. , Phosphorus 0.56%, potassium 1.83%, iron 243.0 mg kg-1 , zinc 78.67 mg kg-1 , fruit content of nitrogen 1.49%, phosphorus 0.77% and potassium 0.73% by compared to control treatment.
