Effect of sowing depth and seed calibration on maize yields



Effect of sowing depth and seed calibration on maize yields



Rostlinna Vyroba 41(1): 11-16



Maize seed placed in different quality categories based on 1000-grain weight was precision drilled at 3 depths with 3 sowing dates in field trials on a degraded chernozem in 1990-92. The effect on yield of sowing depth was 2.5-fold less important than the effect of sowing date and 5-fold lower than that of the year. A 10-mm change in sowing depth caused a yield change of 0.4 t/ha which was further altered by seed shape and size, and hybrid.
