IPM-ПОДХОД С БИОГЕННЫМИ СТИМУЛЯТОРАМИ И БИОУДОБРЕНИЯМИ ДЛЯ БОБОВО-ЗЛАКОВЫХ СМЕСЕЙ: ОБЕСПЕЧЕНИЕ ДОЛГОСРОЧНОЙ РЕЗИСТЕНТНОСТИ К СТРЕССОРАМ ВМЕСТО КРАТКОСРОЧНЫХ УРОЖАЙНЫХ ПИКОВ В КАЛИНИНГРАДСКОЙ ОБЛАСТИ
Green-forage yield (t ha-1, harvest B1) and stability indicators
normalized stability index SI = 1 / (1 + S2di / S̄2d), where S2di is the Eberhart–Russell variance of deviations from regression and S̄2d its mean across treatments (SI = 1.0 = absolute stability); the corresponding Eberhart–Russell regression coefficients bi ranged from 1.18 (A1) and 1.12 (A2) to 0.96–0.98 (A5–A6), i.e. the integrated treatments approached bi ≈ 1 with the smallest deviation variance; based on three environments (df = 1) and thus indicative
