Georgieva, N. and I. Nikolova, 2016. Changes in productivity and quality of forage from pea and vetch under impact of products with different biological effect. Bulg. J. Agric. Sci., 22 (Suppl. 1): 19–24
Production of good quality fodder is of great importance for economical animal production. Both quality and quantity of fodders are influenced by the used plant species, their stage of growth and the applied agronomic practices. The object of this study is to make an assessment of the feeds from main annual legume species – pea and vetch – in quantitative and qualitative terms. Experimental work was conducted in Institute of Forage Crops, Pleven, during the period 2007-2009. The changes in green mass productivity and nitrogen content of fodder under impact of separate and combined use of different products (Atonic, growth regulator; Masterblend, leaf fertilizer; Confidor, insecticide) and phenological stages of application (budding, flowering, budding and flowering) were observed.
