Producţia grâului durum de toamnă în funcţie de îmbinarea unor elemente tehnologice şi a condiţiilor climaterice

Abstract

The purpose of our experiments was to study the role of sowing time and density on the degree of plants‘ wintering, formation of their productivity elements and average yield (kg/ha) as well as the quality of winter durum wheat grains. Depending on the climatic conditions of the Republic of Moldova the yield of winter durum wheat in the unfavorable years was of 674-2763kg/ha, in the less favorable years -1380-5680 kg/ha, and in the favorable years - 1652-6050 kg/ha. The highest quality of winter durum wheat (according to the protein and gluten content in grains) was recorded by Hordeiforme 335 and Delfin varieties sown in late and acceptable terms with the density of 4,5 and 6,5 million germinating seeds/ha, using the peas and vetch as forerunner plants.
