چکیده
This work presents information on the patterns of yield determination by yield
components as a function of the level of management of the crop. The data used for
the analyses were obtained from 8 field experiments located across Poland in 2009
and 2010. 25 winter wheat cultivars were evaluated at two management levels, i.e.,
at a low input of nitrogen fertilisation and pesticides and at a higher input of these
materials. Yield determination was evaluated with a path analysis conducted for
each cultivar separately for each management level. The results were presented
using the values of the path coefficients. The pattern of yield determination for
most of the cultivars examined differed between the high-input and the low-input
management levels. Under the low-input management, all three yield components
contributed similarly to yield determination. Under high-input management, the
effect of the number of spikes per m2 was much greater than the effect of the
weight of an individual grain.
