VNT4, a Derived Formulation of Glutacetine® Biostimulant, Improved Yield and N-Related Traits of Bread Wheat When Mixed with Urea-Ammonium-Nitrate Solution

چکیده
Optimizing nitrogen use efficiency (NUE) could mitigate the adverse effects of (N) fertilizers by limiting their environmental risks and raising agronomic performance. We studied VNT4, a derived formulation Glutacetine® biostimulant, mixed with urea-ammonium-nitrate solution (UAN) on growth, N-related traits performance winter wheat (Triticum aestivum L.). The experiment was performed under six contrasting field conditions over two years in Normandy (France), including site where 15N labelling undertaken. Taking into account all sites, we report that VNT4 significantly improved grain yield (+359 kg ha−1), total N NUE. application growth during tillering stem elongation (+10.7%), uptake between maturity (+7.3% +16.9% 15N) leading to higher accumulation at (+9.3% N). This mainly originated from fertilizer (+19.4% assimilated after flag leaf stage particular (+47.6% 15N). These be related maintenance physiological functions leaves as suggested enhancement nutrient status (especially S, Zn Mo). adoption UAN additive is an efficient practice enhance productivity oceanic temperate climate.
