Abstract
This study was conducted on seedlings of local pear summer variety, one year old, planted in plastic anvils during the 2020 growing season in the wood canopy of the Department of Horticulture and Garden Engineering / College of Agriculture / University of Tikrit, to find out the response of these seedlings to organic fertilization (compost) and the addition of sulphate and spray With cytokinin in the mineral content of the local pear seedlings, a summer variety, where solid organic fertilizer (Compost) was added in three levels (0, 10%, 20%), ferrous sulfate was added in three concentrations (0, 20, 40 mg Fe kg -1 soil) and sprayed with cytokinin (BA) in three concentrations (0, 150, 300 mg. L1), where the high concentration of organic fertilizers (compost) 20%, ferrous sulfate (40 mg Fe kg-1 soil) and spraying with cytokinin (300 mg. Liter 1) gave a significant increase in The leaves content of nitrogen, phosphorous, potassium and iron, the experiment was carried out using the Randomized Complete Block Design (RCBD) with three replications and with one seedling of the experimental unit. The data were collected and statistically analyzed according to the design using the SAS program (SAS, 2001) and the averages were compared to the D test. We were polynomial at a 5% probability level.
