Porównanie wzrostu i plonowania truskawki odmiany 'Aga' uprawianej w glebie zasobnej, nawożonej nawozami o zróżnicowanym składzie chemicznym

Abstract

The experiment conducted at Pomology Research Station of Szczecin Agricultural University permitted to compare the influence of the three fertilizers which have the differentiated chemical composition. Each fertilizer is water-soluble and can by use for fertilization, plant growth and yielding of ‘Aga’ strawberry cultivar. The used fertilizers were Agrasol F316, Kristalon orange and Ammonium nitrate which solution, used for the watering, had the highest EC 2.05 mS.cm–1. Plants fertilized by Agrasol F316 had the biggest leaf area from the one plant (first year of plant growing 2113 cm2, second year of plant growing 3377 cm2), and the biggest area of one leaf (first year of plant growing 81.3 cm2, second year of plant growing 70.2 cm2). In the second year of plant growing plants of this combination also had the highest yield of fruits from the one plant (250 g), in the first year of plant growing they had the highest mass weight (9.69 g). Fruit picked from the plants which were fertilized by Agrasol F316 and Ammonium nitrate had the highest firmness (198–261 G mm–1).
