Abstract
A study was conducted to determine the dry matter yields as well as the nutrient compositions and in vitro digestibility of 9 silage corn varieties grown as main and second crops under Van conditions. In 2020-2021, a study was conducted on 9 corn varieties from different maturation groups during the growing periods of the main crop and the second crop. The main crop was harvested during the transition from milk maturity to dough stage maturity, while the second crop was harvested at the beginning of the milk maturity period. The study determined the crude nutrient (DM, CA, CP, CF, ADF, and NDF) analysis and in vitro dry matter digestibility (IVDMD) of the corn herbage. The Bodega corn variety had the highest DM yield in the main crop, while the KxB6451 corn variety had the highest yield in the second crop. Among the varieties studied, DKC5685 had the lowest DM yield, ADF, and NDF content in the main product. However, it had the highest CP content and IVDMD (P
