Abstract:
This research was carried to determine the yield and yield components on some common bean (Phaseolus vulgaris) varieties in 2017 and 2018 years, in Diyarbakir, southeast Anatolia of Turkey. In the experiment, Onceler-98, Karacasehir-90, Yunus-90, Akman-98,
Goynuk-98, Aras-98, Terzibaba, Adabeyazi, Cihan and Noyanbey cultivars were used. Experiment was set up in randomized complete block design with three replications. Plots were 6 m length with five rows, the inter-row and intra-row spacing were 0.7 m and 0.10 m. Seeds were sown after wheat harvest as second crops. The differences among cultivars were significant for number of days of flowering and maturity, plant height,
number of pods and seeds per plant, grain yield and 100 seed weight. Number of days to flowering ranged from 48.0 to 62.8; number of days to maturity ranged from 99.8 to 113.8. The number of pods and seeds per plant varied from 12.8 to 30.8, and 24.3 to 105.6, respectively. Grain yield ranged from 792.3 kg ha-1 (Cihan and Noyanbey) to 2709 kg ha-1 (Goynuk-98 and Onceler-98). In the experiment area, high heat temperature and high evaporation throughout July and August, negatively affected the blooming, pollination and fertilization on cultivars of dwarf and determinate plant habit types. Brushy type and late-maturing varieties should be preferred under second crop conditions.
