 en Effects of different irrigation methods and plant densities on silage quality parameters of PR 31Y43 hybrid corn cultivar ( Zea mays check for this species in other resources L. var. indentata [Sturtev.] L.H. Bailey)

Abstract

The yield and quality of corn silage is related to genotype as well as factors such as climate, soil conditions, altitude, planting time, plant density, irrigation, and harvesting time. This study was conducted to determine the effects of different irrigation methods (drip, subsoil drip, and subsoil capillary) and different plant densities (102 040, 119 040, and 142 850 plant ha-1) on silage quality parameters of PR 31Y43 hybrid corn ( Zea mays check for this species in other resources L. var. indentata [Sturtev.] L.H. Bailey) in 2011 and 2012 under ecological conditions in Eskipazar-Karabuk, Turkey. Plant densities were significantly different on fresh ear ratio and plant crude protein (CP) yield in both years under study. The highest fresh ear ratio values were obtained with 102 040 and 119 040 plant ha-1 densities and the highest plant CP yield with 142 850 plant ha-1. While the irrigation method × plant density interactions were significant for silage CP ratio in the first year, they were significant on fresh ear ratio in the second year. The highest fresh ear ratio values were obtained from subsoil capillary × 119 040 plant ha-1 and drip × 119 040 plant ha-1 interactions; the highest plant and silage CP ratio values were obtained from subsoil capillary × 142 850 plant ha-1 and subsoil drip × 102 040 plant ha-1 interactions. As a result of the research, high Flieg scores were obtained from each irrigation method and plant density. When plant CP yield is taken into consideration, the 142 850 plant ha-1 density is more important.
