Abstract
The study was carried out at Grdarasha field in Erbil from November 4th of 2019 to April 20th, 2020.The purpose of this study was to study different levels of foliar spray of Atonik (0, 0.2, 0.4, 0.6, 0.8, and 1 ml.L-1) affected the growth and yield of two pea cultivars (Utrillo and Nihal). The majority of the parameters investigated yielded significant outcomes. Cultivars had a substantial reaction on some of the tests, according to the findings. Parameters of pea vegetative growth and yield, the Utrillo cultivar produced the best results. Furthermore, Atonik foliar spraying had a considerable impact. The number of leaves and branches has the biggest influence on vegetative parameters (110.74 and 2.69 respectively), according to the findings (1ml.L-1). From 0.2 ml.L-1 of Atonik the maximum values of vegetative growth, fresh weight, and total chlorophyll were recorded. Atonik foliar spraying also improved yield parameters significantly. However, at 0.2 ml.L-1 of Atonik, the highest numbers of seeds per pod, yield per plant, yield per plot, and yield per hectare (6.00, 0.16 kg, 1.00 kg, and 1.68 tons, respectively) were obtained. Meanwhile, the majority of vegetative development and yield indices, particularly Nihal, exhibited a substantial response to Atonik treatment.
