- Abstract
The spring cereals are the most important grains in Estonian farming. The input of fertilizers and chemicals used by farmers for spring cereal production is quite different. Successful farmers prefer high input. They utilize high levels of fertilizers, herbicides, fungicides, insecticides and growth regulators (Ministry of Agriculture, 2008). The aim of this paper was to investigate the influence of the different levels of fertilizers and chemicals to the agronomic and quality characteristics of spring wheat, barley and oats. The trial was established with two varieties of each spring cereal at the Jõgeva Plant Breeding Institute during 2006-2007. Two input levels of fertilizers and chemicals (high and low input) were used. Four fertilizer doses, treatment by herbicides and insecticides were carried out in low input level (LI). The same fertilizer rates, treatments by fungicides, insecticides, leaf fertilizers and growth regulator were included in high input level (HI). Unfavourable weather conditions (drought) for cereals were observed. The results of this trial showed that there were significant differences between the agronomic and quality parameters of spring cereals at different input levels. Significant yield decrease and protein content increase was estimated in HI conditions. The plant height of wheat and oat varieties decreased with use of HI. There was no significant influence of the inputs to the length of the growing period in drought conditions.
