THE EFFECT OF FOLIAGE FEEDING ON THE STRUCTURE OF YIELD, DRY WEIGHT CONTENT AND MACROELEMENTS IN THE CORMS OF Sparaxis tricolor Ker-Gawl.
The field study was carried out between 2000 and 2003. The plants of Sparaxis tricolor were sprayed twice prior to flowering with a fertilizer called titanium (0.8% Ti) in three concentrations: 0.02, 0.04 and 0.08%. Application of titanium in the concentration of 0.04% increases the total yield of...

Summary: | The field study was carried out between 2000 and 2003. The plants of Sparaxis tricolor were sprayed twice prior to flowering with a fertilizer called titanium (0.8% Ti) in three concentrations: 0.02, 0.04 and 0.08%. Application of titanium in the concentration of 0.04% increases the total yield of corms by 20% on average and the commercial yield by 7%. Spraying the plants with titanium in the concentration of 0.02% increased the share of corms with > 5cm circumference in total yield and improved yield structure of corms of the first selection. A higher concentration of the preparation (0.08%) had unfavorable effect on the commercial yield of corms. In 2001 titanium applied in the concentration of 0.02% increased the nitrogen content in offspring corms and decreased content of other macro-elements. In 2003 offspring corms of plants treated with titanium in the concentration of 0.02–0.04% had more dry weight, N, P, K, Ca, Mg and Na.
