The effect of concentration of nutrient solution on the growth of Calluna vulgaris
‘Allegretto’ cultivated outside on ebb-and-flow
benches was investigated. The standard nutrient solution contained 200 N,
21 P, 83 K and 12 Mg (mg dm-3) and microelements.
EC of the standard nutrient solution was 1.7 mS cm-1.
Half strength (EC 1.1 mS cm-1) and double
strength (EC 2.7 mS cm-1) nutrient solutions
were used in the experiment. The best growth of heathers was noted when
nutrient solutions with 1.1 and 1.7 mS cm-1 were
used. Increased concentration of nutrient solution for fertigation of
heathers resulted in increased accumulation of salt in the growth medium,
especially in its upper layer. Calluna vulgaris ‘Allegretto’
fertigated with a more concentrated nutrient solution had increased N and
reduced Ca and Mg content in the leaves.
