Growth, yield and quality response of two industrial potato cultivars to chelated potassium and humic acid during fall season

TL;DR

This study investigates how chelated potassium and humic acid affect growth, yield, and quality of two industrial potato cultivars during the fall season, providing insights into optimal fertilization practices.

Contribution

It examines the combined effects of chelated potassium and humic acid on two specific potato cultivars, which is a novel investigation for this region and season.

Findings

Enhanced potato growth and yield with combined fertilization

Improved tuber quality due to treatments

Optimal fertilization recommendations for fall season

Abstract

The study was carried out to known the response of two industrial potato cultivars (Hermes, and Challenger) Netherlands origin, to chelated potassium fertilizer and humic acid due to growth, yield and quality in the fall season of 2024, planted in an open field of the educational field of Horticulture Department, College of Agricultural Engineering Sciences, University of Sulaimani, Sulaymaniyah, Kurdistan region, Iraq, with a (GPS) reading (latitude: 35.53576 N, longitude: 45.36663 E), and an Altitude of (741 m) above sea level. A factorial randomized complete block design (RCBD) with three replications was used in this study.
