Efeitos De Diferentes Concentrações De Resíduo Industrial De Suplemento Mineral Para Animal Sobre O Crescimento De Plantas De Girassol

Abstract

Neste trabalho avaliou-se o uso de diferentes concentrações de resíduo de suplemento animal (RSA) para a composição de substratos para o cultivo de plantas de girassol (Helianthus annuus L.) sobre o crescimento e teores de solutos orgânicos. O uso do RSA a 50% ocasionou incrementos no número de folhas, área foliar, diâmetro do coleto e teor de N-aminossolúveis das folhas, em comparação aos tratamentos areia e fertilizante comercial. Assim, o uso do RSA a 50% da RN mostrou-se eficaz, podendo tornar-se uma alternativa viável e ambientalmente vantajosa. Palavras-chave: Adubo mineral. Helianthus annuus L. Resíduo sólido industrial. RESUMOThe study evaluated the use of different concentrations of animal supplement residue (ASR) to the composition of substrates for sunflower plants (Helianthus annuus L.), on growth and organic and inorganic solutes contents. The use of 50% ASR caused increases in the number of leaves, leaf area, stalk diameter and N-aminosoluble content of leaves compared to sand and commercial fertilizer treatments. Thus, the use of ASR at 50% of the RN was effective and could become a feaseble and environmentally advantageous alternative.

“…2). Bezerra et al (2017) obtained similar responses when working with shrimp residue in sunflowers (Helianthus annuus), where the number of leaves increased by 37% with concentrations of 7 g and 14 g of the residue in the substrate, as compared to the control at 19 d of cultivation.…”

“…1). According to Bezerra et al (2017) and Tacon (1989), shrimp head silage is a good source of several mineral nutrients, both for fertilization in plants and the manufacture of feed and food. Nocentini et al (2021) stated that chitin residues generated from shrimp parts can be recycled for use in soils lacking in nutrients such as N and P.…”

“…The transformation of these residues into co-products with added value is vital to minimizing problems in production and achieving greater efficiency in processing (Beerli et al, 2004). Shrimp processing residues have been used for animal feed production, chitin extraction, carotenoid pigments, remediation of contaminated water, plant disease control, water stress and environmental impacts (Vieira et al, 2011;De Souza et al, 2015;Seabra et al, 2014;Núñez-Gómez et al, 2016;Ghini et al, 2006;Bezerra et al, 2017;Decker et al, 2016;Sumardiono and Siqhny, 2019).…”
