Growth and flower bud formation of Rhododendron ‘Blurettia’,
‘Percy Wiseman’, and ‘Bengal’ on ebb and flow benches flooded with
nutrient solution containing 60, 120, and 180 mg N dm-3; 20, 40, or 60 mg P
dm-3 and 60 or 120 mg K dm-3 were evaluated.
The best growth of all cultivars was obtained at 180 mg N dm-3 while
increasing P and K levels did not stimulate growth of plants. ‘Bengal’ did not form
flower buds at all but flowering of ‘Blurettia’ was stimulated by high N level
while for ‘Percy Wiseman’ N level 120 mg dm-3 and increased
K to 120 mg dm-3 ensured the best flower bud set. P level did not affect flowering.
