Effect of row spacing and stand density on silage maize yield

Original language description

Maize growing is still more important in the Czech Republic, mainly growing of silage maize as a major biomass source for biogas stations. Maize grown in a standard row spacing (0.75 m) is connected with high risk of soil degradation by water erosion mainly on sloping plots. Except of conservation tillage technologies, growing of maize in narrow rows is approach aimed on faster canopy closure and water runoff reduction when keeping sufficient yield level. Influence of different row spacing and stand density on silage maize yield was evaluated in a field experiment in the Czech Republic, in maize production area in years 2013-2014. In 2013, statistically significant higher yield was found in case of narrow rows (0.375 m) and twin rows (rows on standard 0.75 m spacing, where each row is further divided into adjacent sub-rows spaced approximately 0.20 m compared to standard row spacing (0.75 m). Only in case of twin rows yield increased with maize stand density (+28% compared to common density). Results from year 2014 were different. There were not statistically significant differences among variants with various row spacing, just as in case of different stand density. The highest yield of dry matter of above ground biomass was at the standard row spacing (0.75 m; 18.76 t ha-1), lower in case of twin rows (18.39 t ha-1) and the lowest in case of narrow rows (17.87 t ha-1). Measurement of meteorological parameters in maize stands with different row spacing shown, that higher soil moisture is in narrow rows, especially in dry seasons.
