TUBER YIELD AND QUALITY OF POTATO FERTILISED WITH INTERCROP COMPANION CROPS AND STRAW
Anna Płaza, Feliks Ceglarek, Danuta Buraczyńska
ABSTRACT
The paper presents the results of research carried out over 1997-2000 which aimed at examining the possibility of replacing manure in potato fertilisation with intercrop companion crops and straw, without decreasing the tuber yield and its quality. In the experiment two factors were studied: I – fertilisation with intercrop companion crop (control, manure, birdsfoot trefoil, birdsfoot trefoil + Italian ryegrass, Italian ryegrass), II – straw fertilisation (without straw, with straw). In the first year after organic fertilisation table potatoes ‘Ania’ were cultivated. It is a mid-late cultivar, very high-yielding, of large high tubers, of multipurpose culinary use, and good taste. Out of all the intercrop companion crop combinations researched, the greatest amount of biomass was introduced into soil by Italian ryegrass, significantly less – by a mixture of birdsfoot trefoil and Italian ryegrass, and the least – birdsfoot trefoil. Potato fertilisation with intercrop companion crops increased
