Abstract

The purpose of this experiment was to define the influence of different doses of calcium chloride (CaCl2) applications on fruit yield, some quality properties, and nutrition of plant in Hicaznar pomegranate cultivar during 2016 and 2017 in Aydın (Turkey) ecological condition. In the study, 0.2, 0.4, 0.6, 0.8, and 1.0% solutions of calcium chloride (CaCl2) were applied by spraying except the control dose to the trees. The solution doses were twice applied during the fruit growing season in June and August. According to the results, fruit yield, peel thickness, fruit length, diameter, and weights were increased compared to control dose with CaCl2 applications. Foliar CaCl2 applications increased foliar Ca content by 60%. Concentrations of other plant nutrients other than N and Ca were decreased in parallel with increasing CaCl2 doses. Foliar P content was not affected in this case. As a result, the amount of CaCl2 solution to be applied to leaves in Hicaznar pomegranate was determined as 0.6%.

Highlights

Pomegranate's homeland Turkey, Middle East, south-southeast of Iran, the Caucasus and including northern India is known to be a large region
Significant relationships were found between application doses and fruit yield (Figure 1)
The highest fruit yield was determined as 23.0 kg tree-1 in the 2016 year and 22.8 kg tree-1 in the 2017 year at 0.6% CaCl2 dose, 22.6 kg tree-1 in the first year and 22.7 kg tree-1 in the second year at 0.8% CaCl2 dose

Summary

Introduction

Pomegranate's homeland Turkey, Middle East, south-southeast of Iran, the Caucasus and including northern India is known to be a large region. The fruit of the pomegranate, which is one of the subtropical climate fruit species, can be evaluated in various ways in the food industry as well as YYÜ TAR BİL DERG (YYU J AGR SCI) 31 (2): 418-424 Toprak / CaCl2 Solution Sprayed on Leaves Changes the Nutrition and Qualitative Properties of Pomegranate Hicaznar) for fresh consumption (Çelik et al, 2019). Pomegranate cultivation is carried out in a wide area from Australia to South Africa, USA and China (Ünal, 2011). Hicaznar pomegranate is one of the main varieties in pomegranate cultivation in Turkey. Turkey's total pomegranate production was realized as 600 021 tonnes in 2020 (TUIK, 2020)
