Dependence of the Content of Proteins on the Seedling Dues and Sort of the Soybean Grain

Abstract

The optimal due for seedling soybeans was found considering comparableresearches about growing soybeans during four different seedling dues atintervals of 10 days (21 March – 21 April ), with two different sorts and twodifferent productive lines of soybeans, the optimal due for seedling soybeanswas found by the aspect to get higher percent of proteins in the grain. Thecontent of the proteins in the grain was analysed according to Kjeldahl,considering the average exemples of grains. The average content of proteins inthe grain during a period of three-year researches (1998 - 2000 ), was 36,72 %,with the biggest percent in the grains from the fourth (37,13), and the smallestfrom the first seedling due 36,50. The biggest percent of proteins contain thegrains from the earliest sort (,,015"). In the year (1999), wich had the mostsprinkles in the vegetation period of the soybean, the percent of the proteins wasthe biggest, in the dryest (2000) it was the smallest.
