“…This was confirmed by Księ żak et al, who found an increasing effect on protein content in soybean, which was significantly increased by about 14% compared to non-fertilized soybean [43]. Efthimiadou et al reported the same fat and protein results after applying various concentrations of N fertilizer treatments, with the protein content varying between 6.39% and 6.71% and fat between 2.93% and 3.0% [44]. The fat levels in maize with fertilizer applied were significantly different, ranging from 3.86% to 4.61% (control 3.42%), and in soybean, they ranged from 19.22% to 22.85% (control 19.09%).…”

This paper presents the effects of organic fertilizers on the yield, quality, and fatty acid composition of maize and soybean in 2022 in Southeast Kazakhstan. Maize and soybean yields were improved by commercial organic fertilizers. In general, the yield, quality, and fatty acid (FA) parameters of both crops were influenced by various types of organic fertilizers. The application of HansePlant fertilizer allowed for an increase in the yield of maize seed by 47% and soybean by 31%. Organic fertilizers improved the quality parameters fat, protein, fiber, and starch in maize by 35%, 22%, 14%, and 8%, respectively, compared to control samples. In soybean, the parameters fat, protein, and fiber were improved by 20%, 3%, and 11%, respectively. The FA compositions of maize and soybean were analyzed via gas chromatography and with tandem mass spectrometer using a polarity column. Compared with no fertilization conditions, the omega-6/omega-3 ratio showed the lowest value in maize (22.40–123.96) and soybean (3.26–4.07). A study of the fatty acid composition groups compared with different fertilizer treatments was performed.

Biostimulant Application, under Reduced Nutrient Supply, Enhances Quality and Sustainability of Ornamental Containerized Transplants

2023

View full text Add to dashboard Cite

Ornamental containerized transplant production needs high doses of controlled release fertilizers (CFR), but it is known that there is an environmental risk caused by inadequate fertilization management. To the best of our knowledge, amino acid-(AaB) and seaweed extract-(SeB) based biostimulant application, in ornamental transplant production, is still poorly studied. Therefore, the aim of this work was to assess the hypothesis that, under reduced nutrient supply, SeB and AaB applications, via foliar spray, can promote quality and sustainability in the production of high-quality ornamental seedlings with a 90-day growing cycle. The CRF incorporated into the peat-growing medium was Osmocote Exact Mini in formulation N:P:K = 15 + 9 + 11 (3 months). Six treatments were compared in two economically important potted (0.3 L in volume) ornamentals: Abelia × grandiflora and Lantana camara: T1 = conventional full CRF dose: 4 gL−1 per pot; T2 = limited CRF dose: 50% of T1; T3 = T2 + MC-Extra® [SeB 0.5 gL−1]; T4 = T2 + MC-Extra® [SeB 1.0 gL−1]; T5 = T2 + Megafol® [AaB 1.5 mL L−1]; T6 = T2 + Megafol® [AaB 2.5 mL L−1]. The research results showed that the application of 50% CRF plus biostimulant application resulted in plant performance greater than or equal to those raised under the conventional CRF full dose. In particular, S1 (Abelia × grandiflora ‘Edward Goucher’) and S2 (Lantana camara ‘Little Lucky’) behaved differently concerning the Megafol® dose under 50% CRF; compared to T1, in A. × grandiflora young transplants, T5 increased root morphological characteristics, as well as number of leaves, leaf area, and dry biomass accumulation; in L. camara, T6 achieved higher performance. The application of biostimulants under 50% CRF also improved, in both A. × grandiflora and L. camara, the physiological and agronomical Nitrogen Use Efficiency, compared to a full CRF dose. This study can support decision-making in terms of agronomic technique choices in line with the sustainable development of high-quality ornamental transplant production.
