REASONS FOR THE LOSS OF WINTER CROPS AND THEIR SOWING DATES IN REGIONS OF POVOLZHE (REGIONS ALONG THE VOLGA)
Abstract
The harvest of winter crops depends to a considerable degree on the quality of sowing, on the presowing preparation of the soil, previous crops, periods of sowing, use of variety seeds of regionalized varieties, application of fertilization, etc. One of the most important agrochemical measures in this is observation of optimum periods of planting, which is especially necessary in regions where the falls are usually dry periods. Due to the fall dry period winter crops in the regions of Povolzhe were reseeded over a considerable area in 1945, 1947, 1950, 1954, 1956, and 1960.
