Abstract

A field experiment was conducted in Borki-Wyrki, Zbuczyn Gmina (commune), from 2017 to 2019. The objective was to assess yield performance and morphological characteristics of two spring triticale cultivars as affected by multi-nutrient fertiliser type and rate, the fertilisers being Polifoska 6 and Polifoska Krzem. Three experimental factors were tested: spring triticale cultivar – Milewo and Dublet, mineral fertiliser type – Polifoska 6 and Polifoska Krzem, and mineral fertiliser rate –0 kg∙ha−1, 140 kg∙ha−1, 280 kg∙ha−1, 420 kg∙ha−1. Spring triticale plant development and yield performance were significant affected by experimental factors, that is cultivar, fertiliser type and rate, were shown to influence these characteristics. Superior yields were produced by cv. Dublet compared with cv. Milewo. Cultivars fertilised with Polifoska Krzem produced higher grain yields than Polifoska 6. An increase in fertiliser rate was followed by higher grain yields. Spring triticale cultivar as well as multi-nutrient fertiliser type and rate significantly affected ear length. Significantly longer ears were developed by cv. Milewo. Longer ears were developed by cereal plants fertilised with Polifoska 6. Similarly, higher fertiliser rates had a beneficial effect on ear length. Fertiliser rate contributed to a significant increase in plant height compared with unamended control. Cv. Milewo plants were significantly higher than cv. Dublet plants.
