Abstract

The aim of the paper is to show the reaction of maize crop to the foliar application of new biofertilizers, obtained from the residues left after the wool tanning process and which are based on protein hydrolysates of keratin and collagen. The tests have been performed in microplots (10 sqm) and macroplots (1000 sqm), in three repetitions, in southern Romania. All data obtained as a result of the 2020 autumn harvest have been centralized in tables and statistically processed, in order to establish the influence of each product, compared to the control. The bifactorial analyses show that, in climatic stress conditions (prolonged drought – Calarasi), very significant increases in yield have been obtained with K4 (2.5 and 5.0 l/ha), K5 (5.0 l/ha) and C (5.0 l/ha), with increases between 700 and 1300 kg/ha, ie up to +24%. In macroplots, subject to a moderate drought (Teleorman), product C (5.0 l/ha) brought a yield increase of 1537 kg/ha (+26%), noting that in this location almost all tested biostimulators offer very significant yield growth (except KC). Based on the 2020 yields, it was possible to identify which the foliar biostimulators that will continue to be tested in 2021.
以动物源性角蛋白和胶原蛋白水解物为基础的新型生物刺激剂对玉米叶片施肥后的产量结果
本文的目的是展示玉米作物对叶面施用新型生物肥料的反应,这种新型生物肥料是从羊毛鞣制过程中留下的残留物中获得的,它是基于角蛋白和胶原蛋白的水解产物。在罗马尼亚南部的小地块(10平方米)和大地块(1000平方米)中进行了三次重复试验。2020年秋收获得的所有数据都已集中在表格中并进行统计处理,以确定每种产品与对照相比的影响。双因子分析表明,在气候胁迫条件下(长期干旱- Calarasi), K4(2.5和5.0 l/ha)、K5 (5.0 l/ha)和C (5.0 l/ha)的产量显著增加,增产幅度在700至1300 kg/ha之间,即高达+24%。在大样地,受到中度干旱(Teleorman)的影响,产品C (5.0 l/ha)使产量增加1537 kg/ha(+26%),注意到在这个位置,几乎所有测试的生物刺激剂都提供了非常显著的产量增长(KC除外)。根据2020年的产量,有可能确定哪些叶面生物刺激剂将在2021年继续进行测试。
