Comparison of the Yield of Buckwheat (Fagopyrum esculentum) Varieties under the Climatic Conditions of Kabul
Buckwheat is gaining attention as a promising crop because of its nutritional value and ability to grow under diverse environmental conditions. This study investigated the performance of three buckwheat varieties Common Buckwheat, Devyadka, and Zyloni under the agro-climatic conditions of Kabul during the 2025 growing season. The field experiment was carried out at the Research Farm of the Faculty of Agriculture, Kabul University, using a randomized complete block design with four replications across two contrasting field environments. Several growth characteristics, including plant height, leaf number, leaf width, and number of branches per plant, together with total biomass and 100-seed weight, were evaluated. The results revealed that plant height, leaf number, leaf width, and total biomass varied significantly among the varieties and between environments, with a clear interaction between genotype and environmental conditions. These findings indicate that the growth and productivity of buckwheat are strongly influenced by the environment in which each variety is cultivated. In contrast, the number of branches per plant and 100-seed weight remained relatively stable across environments, suggesting that these traits are less affected by environmental variation. Among the tested varieties, Devyadka produced the greatest vegetative growth and biomass under favourable conditions but showed greater sensitivity to environmental changes. Common Buckwheat maintained consistent performance across both environments, demonstrating strong adaptability and stable productivity, while Zyloni displayed moderate performance with reasonable stability. The study concludes that environmental conditions play an important role in determining buckwheat performance in Kabul. Considering both yield potential and stability, Common Buckwheat is the most suitable variety for cultivation under the variable agro-climatic conditions of the region.
