Influence of Autumn Irrigation to the Consumption of Soil Moisture and Oats Green Mass Value in the Lena River Valley
Abstract
In summer 2016 observations were made on the consumption of soil moisture of oats sowing for grass mass under autumn irrigation conducted in autumn 2015 in the area "Moydooh" of agricultural firm "Ne- myugyu" (3 km from the town of Pokrovsk) on the territory of Khangalassky district of the Republic of Sakha (Yakutia). The first half of the year was dry and the second half was relatively moisture. Yet at the site with autumn irrigation with norm of 500 m3/ha the highest yield of green mass of oats (142.6 kg / ha) was pro- duced than at a bogara area (116.7 kg /ha). The value of evapotranspiration over the observed period on the area with irrigation was 195 mm and on the rainfed area – 172 mm.
