Changes in the productivity potential of the durum wheat by influence of some biological-active substances
2007
Delchev, G. | Ivanova, I.
During 2004-2006 on pellic vertisol soil type was carried out a field experiment with durum wheat cultivar Beloslava. Five stimulators - Tritimil in dose 30 ml/da, Trisalvit in doses 30 and 50 ml/da, Salvit in doses 50 and 70 ml/da, MPU in doses 30 and 50 ml/da, APC in doses 30 and 50 ml/da, were treated in tillering stage of the durum wheat. Stimulators Tritimil, Trisalvit, MPU and APC shorten 1-st and 2-nd over-ground intermodes'length and increase its diameter. Stimulator Salvit shorten the length, but decrease its diameter. Grain yield is the highest by treatment with Trisalvit, Salvit and Tritimil - 108.9% - 110.2%. The yield increase is due to increasing in spikes number per 1m2 and main and second tiller' structural elements.
