The Effect of Foliar Fertilization on the Resistance of Pea (Pisum sativum L.) Seeds to Mechanical Damage

The aim of the study was to investigate effect foliar fertilization on morphological and mechanical properties pea seeds (Pisum sativum L.) determine dependences between features chemical composition their susceptibility damage. Field experimentation carried out in 2015–2017 (south-eastern Poland, 49°59′ N, 21°57′ E). Micronutrient conventional (N1) organic fertilizer (N2) were tested eight cultivars. parameters assessed included compression force (FD), relative deformation (DR), energy (ED). Application increased strength ability resist damage under quasi-static loads. plants fertilized with N1 more resistant than N2. Seeds larger dimensions, mass, density, a spherical shape damaged action less energy, they deformed less. higher protein, fat, ash, K content lower NFE, Fe, Zn, Cu mathematical models created provide knowledge about impact seeds.
