| Despite the fact that potato planting date experiments have a long history in different potato-growing regions of the country, the results have been accompanied by many differences. With the aim of reaching a single guideline also examining the degree of convergence and consistency of the desired effects of planting date on yield and water use efficiency in potatoes, research conducted in different regions of the country over a 20-year period from the beginning of 2000 to 2019 was subjected to meta-analysis. All initial studies conducted during this period and related to the effect of potato planting date were separable into two groups: autumn (continuation plan) and summer planting date. The results of meta-analysis of studies conducted on planting date revealed that there was a significant difference (P≤0.05) in the effects of planting date on potato yield in both autumn and summer planting groups. Studies conducted in autumn planting date were more homogeneous compared to summer planting date. Totally, the yield of autumn planting dates was significantly lower than that of summer planting. As a result, the average yield in autumn planting across all studies was 19.73 tons per hectare, which showed a significant difference compared to summer planting with an average of 27.65 tons per hectare. Although delayed planting in summer potatoes reduces yield by four to five tons per hectare, it increased water use efficiency by 1.85 kilograms per cubic meter of water consumed. In other words, approximately 25% to 27% of the water consumption for potatoes is saved. | ||
