Protective effects of ultramicroelement salts under water deficit: a case study of buckwheat grown at varying soil available phosphorus levels
Submitted by Гость (not verified) on Sun, 03/08/2026 - 23:08This paper presents the findings of a three-year pot experiment investigating the protective effects of pre-sowing seed treatment with solutions of selenium, vanadium, tungsten, and iodine salts on the biometric characteristics, yield, and grain quality of buckwheat. During the early budding stage, a subset of plants was subjected to an artificially induced water deficit. The study was conducted on two soils of the same subtype but with differing levels of available phosphorus. To ensure adequate mineral nutrition, all pots were amended with N (150 mg/kg) and K 2 O (100 mg/kg of soil).
