Abstract
The investigations were carried out in 2004 – 2005 in the experimental orchard at Garlica Murowana in the Krakow area. The effect of late spraying with 0.8% Ca(NO3)2 on calcium content as well as nutrient mutual relations between mineral constituents in ‘Elise’ fruit of 5 year old apple tree were studied. Trees were sprayed 3 times at 10-day intervals before fruit harvest. Fruit mineral composition was estimated 10 days after each treatment and after harvest. In general, foliar spray with calcium nitrate increased Ca concentration in fruits determined both after treatments and after harvest however this effect was modified by weather conditions in particular experimental years. Sprays with calcium nitrate significantly decreased N/Ca and K/Ca ratio in fruits analyzed after treatments as well as freshly harvested fruits, however only in 2005.
