Abstract

Cauliflower roots were used in an experiment that was conducted at the College of Agriculture, University of Diyala, during the fall agricultural season of 2020 in order to investigate the impact that chemical fertilizer and spraying with nano fertilizer had on the growth of the cauliflower roots. The recommended addition of two thirds of the total recommended amount, as well as the addition of the recommended amount of chemical fertilizer, which is three hundred kilograms per hectare, and three different levels of nano fertilizer (calcium oxide) with concentrations of zero, fifty, and one hundred parts per million (ppm). The treatments were dispensed in an international experiment with three replications in accordance with the design of randomized complete sectors (RCBD), and the results were compared using the Duncan test with a significance level of 0.05. The following is a summary of the findings from the experiment.The use of chemical fertilizer with the full recommendation led to a significant increase in the weight, length and root diameter of plant-1 it reached  (77 gm plant-1, 17.55 cm and 4.62 mm), respectively. Spraying the nano-fertilizer at a concentration of 50 ppm led to a significant increase in the weight, length and diameter of the roots to 101 gm plant-1, 21.33 cm and 5.95 mm) compared to the control treatment, which recorded the lowest values were (81 g, 18.67 cm and 4.80 mm), respectively. While the interaction between the full recommendation of chemical fertilizer and nano fertilizer with a concentration of 50 ppm resulted in a significant increase in all studied traits.
