Abstract
Here we report the results of a three-year replicated field trial on the effects of novel clover- and alfalfa-based fertilizer products (Ekofert® K and Ekofert® L), with the input levels equivalent to 120, 180, or 240 kg N ha−1, on the yield and selected sensory and nutritional quality parameters of onion. The study showed that Ekofert fertilizer applied at all three levels produced similar or higher yields than the standard fertilization regimes used in conventional farming in all three seasons. Significant differences in onion composition profiles between fertilization treatments were detected within individual seasons; however, due to substantial interseasonal variation, no consistent differences could be detected between (i) mineral N and Ekofert fertilizer treatments, (ii) the two different Ekofert products, and (iii) contrasting Ekofert input levels. Results demonstrate that clover- and alfalfa-based pelleted organic fertilizer products are a suitable alternative for intensive organic field vegetable production.

- Grant note
- The study was conducted with the contribution of the LIFE+ financial instrument of the EU and co-financed by the National Fund for Environmental Protection and Water Management (grant number LIFE10 ENV/PL/661). The onion composition analyses were funded by the Polish Ministry of Science and Higher Education with funds of the Institute of Human Nutrition Sciences, Warsaw University of Life Sciences (WULS) for scientific research. The article processing charges were covered with a grant from the Financial Support System for Scientists and Research Teams in the Warsaw University of Life Sciences (awarded in 2020 to D.Ś.-T., grant number 504-02-780400-S00123-99).
