تغییر شرایط آب و هوایی و امکان کشت پاییزه نخود در مناطق سرد برای افزایش بهره وری آب و تولید نخود دیم

In order to study the evaluation of yield and yield components of chickpea genotypes in autumn cultivation in rainfed cold regions, an experimental as factorial was conducted based on randomized complete blocks design in three replications at the farm of Agricultural and natural resources of Ardabil Research Station (Alarouq) in 2021-2022. The experimental factors were included 36 lines and varieties of chickpea from the international treasury lines CAT-2021 sent from Icarda. The results showed that plant height, days to 50% flowering, days to physiological maturity, 100 grain weight and grain yield were influenced by chickpea cultivars. The highest plant height was observed in chickpea genotype No. 8 (67 cm) and the lowest value of this trait was observed in chickpea genotype No. 26 (41 cm), which had an increase of 63.41%. Also, the highest number of days to 50% flowering and days to physiological maturity were obtained in number 36 and 17 of chickpea genotypes (144 and 188 days, respectively). The highest 100 grain weight was observed in number 18 of chickpea genotype (52 grams), also, number 4 and 15 of chickpea genotypes (50 g) also had more 100 grain weight. The highest grain yield was observed in number 9 of chickpea genotype (2492 kg/ha) and the lowest in number 21 of genotype (1308 kg/ha), which had a statistical difference of 90.51%.
