The effect of different calcium sources and doses on the production and quality of potatoes

This study was conducted to determine the effects of different calcium sources and doses on plant growth, yield, and quality traits in the Hasaköy village of Niğde province in 2020. In the experiment, Jelly variety was used, and in tuber plantings, each plot consisted of four rows with a length of 5.1 meters, 70 x 30 cm apart. The experimental design consisted of split plots in randomized blocks with three replicates. In the experiment, different calcium sources (calcium nitrate and calcium chloride) were placed in the main plots, and calcium dose applications (Ca0:0 kg/ha, Ca30:30 kg/ha, Ca60:60 kg/ha, Ca90:90 kg/ha, Ca120:120 kg/ha, Ca150:150 kg/ha) were placed in the sub-plots. Calcium was applied to the leaves by spraying on the 55th day after planting. As a result of the study, it was found that calcium application did not change the number of tubers per plant, but increased the tuber yield and first class tuber rate per plant. Moreover, application of high doses of calcium decreased the rate of secondary structure tuber, but increased the dry matter and starch rate. In our study, tuber yield increased depending on the increase in calcium dose and the highest tuber yield was obtained from 5627.2 kg/da and 150 kg/ha calcium application. High doses of calcium adversely affected the color quality of the chips and French fries. Keywords: Solanum tuberosum, calcium, dry matter, tuber yield, chips color
