Effect of early and late sowing systems on some productive traits of several local barley varieties (Hordeum vulgare L.) grown in zone A

Abstract

 The productive efficiency of seven local varieties of barley (Furat1- Furat2- Furat3- Furat4- Furat6- Furat9- Arab Abyad) was evaluated under the influence of the early (11/18/2021) and late (1/1/2022) planting dates in the Kafr Hamoul region in northern Syria (zoon A) in order to determine the best date for cultivating the varieties, which corresponds to the highest grain yield of the cultivar. Cultivation was carried out according to the random plot design (RCBD) in the arrangement of split plots. It was also noted that planting at the late date gave fewer days to maturity. It was noted that the Furat 4 variety was the best in grain yield (8650 kg / ha), and the cultivar Arabi Abyad was the best in the number of produced cuttings (13.33) and the weight of 1000 grain was (47.37 kg) and the biological yield was higher in the Furat 9 cultivar planted in the early date (39033 kg/ha), and the grain yield was higher when cultivar Furat 4 was planted in the early date (9920 kg/ha).
