YIELDS OF SPRING COMMON WHEAT AND SPRING BARLEY DEPENDING ON TECHNOLOGICAL SUPPORT
Abstract
Results are given from studies on the effect of intensive cultivation technology on yield attributes of spring common wheat and spring barley grown in the forest-steppe areas near the Ob in Ordynskiy District of Novosibirsk Region in 2014–2016. There were studied varieties of spring barley and spring common wheat of various maturity groups under conditions of conventional and intensive farming. When the intensive cultivation technology was used, the increases in yields of Novosibirskaya 31 and Novosibirskaya 18 cultivars of wheat made up 37.7 and 45.5%, and those of Biom and Omskiy Golozerny 2 cultivars of barley – 44.3 and 54.1%, respectively. The following attributes were observed to increase significantly in all the cultivars studied: the number of kernels per spike,housand-kernel weight, the number of spikelets per spike. Close correlation was revealed between productivity of spring barley and such attributes as grain weight per plant, the number of kernels per spike, and thousand-kernel weight. It has been found that the intensification level has the greatest influence on phenotypic variation of the number of kernels per spike, grain weight per spike and crude glutencontent in spring wheat; the number of kernels per spike, thousand-kernel weight and the number of spikelets per spike in spring barley; as well as on the productivity of these crops. The influence of the genotype on these traits is somewha lower than that of the intensification level.
