EXPLORING THE IMPACT OF IRRIGATION TECHNOLOGIES ON THE YIELD OF HYBRID SUNFLOWER VARIETIES
A Polish experience with 10 hybrids of sunflower field was made on the Chelopechene Field, Sofia, on cinnamon forest soil. Sunflower hybrids are grown under non-irrigating conditions and under irrigation conditions with drip irrigation and microwaving.
The meteorological conditions during the study period determined the number of irrigations and the size of the irrigation and irrigation norms of the culture.
It has been found that the yields obtained under irrigation conditions are higher than 13 to 46%, with drip irrigation giving better results than sprinkling.
The Maritsa, San Luka and A58xC23 hybrids have been shown to be suitable for growing in non-irrigated conditions, while the hybrids "Vokil", "Michaela" and "Maritsa" hybrids are irrigated.
