Effect of Irrigation, Nitrogen Fertilization and Amino Acid Biostimulant on Proximate Composition and Energy Value of Pisum sativum L. Seeds

The study investigated the impact of biological and agricultural conditions on chemical composition energy value pea seeds for poultry feed. In experiment, species assessed was (Pisum sativum L.), a determinate form, cultivar (cv.) Cysterski. During field response peas to following experimental factors assessed: first factor—irrigation (yes, no), second factor—nitrogen fertilization (0, 20 40 kg N·ha−1), third factor—amino acid biostimulant no). both years experiments, representative seed samples were collected, in which content dry matter, crude protein, fat, fiber, nitrogen free extract. Additionally, order assess suitability evaluated as feed, expressed form apparent metabolizable (AMEn) estimated. protein increased after application biostimulant, with without irrigation. Statistically significant differences fiber found under influence interaction irrigation fertilization. use significantly seeds.
