Effect of L-Tryptophan and L-Glutamic Acid on Carrot Yield and Its Quality

Positively affecting crop quality and yields, amino acids used as plant stimulants play a special role in ensuring global food security. L-tryptophan (L-Try) L-glutamic acid (L-Glu) are important biostimulants that increase the yield of field crops vegetables. Carrot is one most vegetables due to its production volume world (sixth consumed vegetable) nutritional value. The response different species application varies. literature mainly deals with effects ready-made products containing mixture several acids, no exhaustive studies on individual carrot yield. This paper based two-year experiment (2019–2020), which effect two L-Trp (7.5 g·ha−1) L-Glu (60.0 g·ha−1), (Daucus carota L.) was investigated. They were applied leaves (FA) or both soil (S + FA), separately, (L-Trp L-Glu) L-Glu). control plot treated mineral fertilizers only. research conducted split-block design. storage roots their content dry matter, protein, sugars, total soluble solids (TSS), ascorbic determined. positively affected carrots compared control, but only synergistic action increased it significantly. On average, for S FA protein marketable significantly more than treatment. A significant found after combined foliar FA) all combinations, worked best. grown contained TSS those plot. also by own, while acid. Amino sugars when FA). Of treatment made possible obtain highest yields roots, solids.
