|
|
The article studies the influence of the different time sowing periods of Volzhsky First winter barley variety on the grain yield and the elements of its structure in the conditions of LLC “Vpered” of the Spassky district of the Nizhny Novgorod region on light gray forest soil. Research was conducted from 2015 to 2018. The barley was sown in four periods: from August 20 to September 19 (with an interval of 10 days) with the clean fallow as its predecessor. We used the seeding rate of 2.5 million seedlings per hectare.
Over the 3 years of research field germination of seeds was 77,6-80,0%. Тhe average best preservation rate of plants was 63.5% with a planting date of 9 September. The maximum grain yield of the winter barley was 3.94 t / ha. This corresponds to the sown date of August 20, the density of productive stalk of 226 pieces / m2 and an ear productivity of 1.800 g.
