The Impact of Spur Site and Foliar Application of Zinc and Boron in some Specifications, of Apples (IBrahimi variety)

Abstract

Studying the impact of spur location and zinc and boron spraying on certain growth and flowering characteristics and yield of the Ibrahimi apple variety was conducted in one of the private orchards in a city in the Al-Saqlawiyah sub-district, Fallujah district, Anbar governorate, during the seasons 2021 and 2022. Fifty-four trees with rather consistent growth were chosen at the age of five years and planted on plots measuring 4 meters by 4 meters. The trees were sprayed with zinc (ZN0, ZN1) and boron (B0, B1, B2) twice yearly in a factorial experiment with a 3X3X2 RCBD randomized complete block design, where the first factor represents the selection of the spur site and its symbol (S1, S2, S3), the second factor is spraying, and the third factor is spraying. A considerable rise in the investigated characteristics was seen after spraying with the components under investigation (average fruit size, average fruit diameter, percentage of fallen fruits and percentage of remaining fruits).
