This study aims to evaluate the effects of new-BioFertilizing Amendments (BFAs) deriving from fast organic matter decomposition of Animal ByProducts (ABPs) in comparison with ordinary soil organic amendments (compost), mineral N-fertilizers and no fertilization, on durum wheat development and production in a field trial under Mediterranean conditions. Results showed taller plants with heavier spikes and greater vigor in plots fertilized with BFAs when compared to no fertilization and N-fertilization, respectively. Likewise, BFAs fertilization resulted in higher protein content, gluten content, protein yields and higher values of yellow index with respect to no fertilization and N-fertilization. In contrast, lower values for test weight in correspondence of BFAs fertilization as well as no statistically significant differences on grain yield and gluten index were found. These preliminary results suggest that replacing N-fertilization with BFAs can be effective to ensure crop quality and yield stability in Mediterranean conditions.
本研究旨在通过田间试验，在地中海条件下，评估源自动物副产品（ABP）快速有机物分解的新型生物肥料改良剂（BFA）与普通土壤有机改良剂（堆肥）、矿物氮肥及不施肥相比，对硬粒小麦生长发育和产量的影响。结果表明，与不施肥和施氮肥的地块相比，施用BFA的地块植株更高，穗更重，活力更强。同样，与不施肥和施氮肥相比，施用BFA可提高蛋白质含量、面筋含量、蛋白质产量以及黄度指数值。相比之下，施用BFA时容重较低，且在籽粒产量和面筋指数方面未发现统计学上的显著差异。这些初步结果表明，在地中海条件下，用BFA替代氮肥可有效确保作物品质和产量稳定性。
