Özet:

Approximately 12% of Turkey's chickpea (Cicer arietinum L.) production has occurred in Kırşehir. Due to abiotic and biotic factors that can be experienced in chickpea production, different levels of yield and quality losses can be happened. One of the important biotic stress factors affecting chickpea production is weeds. This study was carried out as a survey study in order to determine the types of weeds seen in the chickpea production areas of Kırşehir province in 2021 and to determine their densities and prevalence in the production areas. This study was conducted as field observations in 57 randomly selected production areas to represent the Kırşehir chickpea production areas. In this study, 64 weed species included in 25 different families were determined. According to our records, 32 species were annual, 5 of them biennial, 18 of them were perennial, 4 of them were annual or biennial, 3 of them were annual or perennial, 1 of them was biennial or monocarpic and 1 of them was parasitic. The average weed density in the study area was determined as 10.19 pieces/m2. Average weed species density per unit area (number/m2), respectively; Hordeum vulgare L. (2.46), Avena fatua L. (1.41), Convolvulus arvensis L. (1.29), Cirsium arvense (L.) Scop. (0.58). The frequency of occurrence in the examined areas, respectively; Avena fatua L. (61.40%), Convolvulus arvensis L. (52.63%), Chenepodium album L. (47.36%), Salsola kali L. (29.82%), Cirsium arvense (L.) Scope. (28.07%), Polygonum aviculare L. (26.31%), Chrozophora tinctoria L. (22.8%), Chondrilla juncea L. (21.5%), and Boreava orientalis Jaub.Et Spach. (21.5%) was determined. As a result, it is considered primarily necessary to control the species that are commonly identified in chickpea production areas.
