“…Jayanudin et al . [ 26 ] also found similar results, demonstrating that chitosan microspheres exhibited acceptable sphericity and smooth surface despite inconsistent diameter. Chitosan microspheres have a great spherical morphology with shiny surfaces [ 27 ].…”

Background and Aim: Irradiated chitosan can be used as a matrix for slow-release urea (SRU) production. This study aimed to (1) determine the optimal formulation of irradiated chitosan matrix for controlling nitrogen release and (2) evaluate the characteristics of SRU in vitro fermentation based on irradiated chitosan as a feed supplement. Materials and Methods: In the first phase of the investigation, four chitosan-based SRU formulations with varying amounts of acrylamide (3 and 5 g) and gamma irradiation (5 and 10 kGy) were evaluated. Scanning electron microscopy, Fourier transform mid-infrared spectroscopy, and ammonia release characteristics were used to observe morphological, functional group, and ammonia release characteristics. In the second phase of research, the most effective SRU formulation was utilized as a supplement to ruminant rations based on rice straw, sorghum straw, and alfalfa. Gas production, rumen fermentation characteristics, and methane gas production were observed in vitro. Results: On the basis of surface image analysis, the four SRU formulas generate a similar appearance. Compared with untreated urea, the SRU3 formula reduced the percentage of ammonia emission by 12.85%–27.64% after 24 h of incubation (p = 0.05), as determined by the first phase study. SRU3 became the basis for the second testing phase. The addition of SRU3 did not affect the optimal gas production in vitro. SRU3 treatment produced less gas than Optigen® treatment (p = 0.05). With regard to rumen fermentation and digestibility, Optigen® yielded better results than SRU3 (p = 0.05). However, the treatment with SRU3 resulted in reduced methane production compared to that in the control (p = 0.05). Conclusion: Irradiated chitosan as an SRU matrix may control the release of ammonia in the rumen medium. The SRU3 formulation is the most effective. The addition of SRU to rice straw-based rations reduces methane production without affecting in vitro digestibility. Keywords: fermentation characteristics, irradiated chitosan, ruminant, slow-release urea.

“…Sin embargo, la acumulación de materia seca (0.66 ± 0.03 g) fue mayor con el tratamiento de 1.0 mg L -1 . En este sentido, se ha reportado el papel del quitosano en el estímulo de la maquinaria fotosintética, en la que se incluye la regulación de la fotoquímica primaria, amplif icación de la f ijación de carbono estomatal y síntesis de carbohidratos (Ahmed et al, 2020;Jayanudin et al, 2021). Así mismo, impacta en la tasa de absorción y acumulación de nitrógeno en los tejidos vegetales, lo que se manif iesta en la acumulación de materia seca y en la ef iciencia fotosintética (Salachna y Zawadzińska, 2014).…”

Agave salmiana L., es una planta con alto valor agroecológico, agroindustrial y gastronómico, sin embargo, su propagación tradicional por hijuelos reduce su variabilidad genética. El objetivo de esta investigación fue evaluar la acumulación de materia seca, clorof ila total y algunos compuestos nitrogenados como respuesta a la aplicación foliar de quitosano en plántulas de A. salmiana. El estudio se realizó en el Instituto Tecnológico Superior de Huichapan, México. El diseño experimental fue completamente al azar con 10 repeticiones. Se evaluaron cinco dosis foliares de quitosano (mg L-1) (0.10, 0.25, 0.50, 0.75 y 1.0), donde T0 corresponde al testigo (agua destilada). Los parámetros evaluados fueron altura de planta, diámetro del tallo, número de hojas, longitud y volumen radicular, materia seca, clorof ila total, nitrógeno total y nitratos. La aplicación foliar de 0.75 y 1.0 g L-1 incrementaron la altura de planta, diámetro de tallo, número de hojas, longitud y volumen de raíz. Sin embargo, la dosis de 0.5 g L-1 también mostró efecto signif icativo en la altura de planta y el diámetro de tallo. Por otro lado, los tratamientos con 0.5, 0.75 y 1.0 mg L-1 mostraron los valores más altos de clorof ila total, nitrógeno total y nitratos, aunque la acumulación de materia seca, solo fue signif icativa con la dosis de 1.0 mg L-1. La aplicación foliar de quitosano es una alternativa que podría ayudar a mejorar algunas de las características morfof isiologicas en plántulas de A. salmiana, una especie endémica de México.

“…The results showed that the maximum urea loading could go from 107 to 200% and its release rate reached the equilibrium condition between day 28 and day 30 with a cumulative amount of about 80%. Jayanudin et al instead proposed the employment of CS as microspheres for carrier material for the controlled release of urea . The formulation is based on an emulsion obtained by using glutaraldehyde saturated toluene (GST) as the cross-linking agent.…”
