“…Gliricidia results demonstrate fast nutrients release, with 79% of P, 99% of K, 91% of Ca and 82% of Mg released of leaves after 70 days of incubation (Zaharah;Bah, 1999) and 74%, 87% and 94% of N, P and K released from fragmented thin branches after 15 days of decomposition, respectively (Pérez-Marin et al, 2018). In the present study, the release rates were slower, possibly because whole branches were used.The t1/2 occurred between 39.5 days (K) and 63.5 days (N) in the first evaluation; between 60.5 days (K) to 90.0 days (Ca) in the first evaluation; between 46.8 days (K) and 135.1 days (S) in DM-GLI, without adjustment in the Ca equation in the third evaluation.…”

“…The results obtained generate mathematical models, including the single and double exponential (Petit-Aldana et al, 2019), generating decomposition and nutrient release curves. Some species have a rapid decomposition, such as Gliricidia sepium (Kaba et al, 2019;Paula et al, 2015;Pérez-Marin;De Arruda Sarmento;Vendruscolo, 2018). Other species tend to be more recalcitrant and slow to decompose, such as Inga edulis Nygren;Mcgraw, 2006), Inga semialata (Silva et al, 2008) and Inga subnuda (Duarte et al, 2013).…”

Agroforestry consortia increase organic matter and nutrient cycling in agricultural systems. For this reason, the objective of this work was to study the release rate of nutrients and the decomposition of different organic residues, two times of the year, obtained from four cultures intercropped with conilon coffee, aiming to relate the released nutrients to the coffee needs. The decomposition of organic matter residues and the release of nutrients from Inga edulis, Musa spp, Gliricidia sepium, and Bactris gasipaes were evaluated in two different periods. I. edulis residues with a higher amount of polyphenols, and those of Musa spp, with a higher C/N ratio, showed slow decomposition. The decomposition rates were lower in experiments started in March and higher in August. Inga and banana have high residual values of nutrients at 270 days in the decomposition started in March.

“…Gliricidia, in turn, is a drought-tolerant, tree leguminous species that has been cultivated as a source of forage and firewood in rural properties in the semiarid region [5]. In addition, the use of this leguminous plant in intercropping can bring other benefits, such as soil decompaction in deeper layers through its root system and also the increase in nitrogen content in soil via biological fixation, improving its chemical and physical quality [6]. Despite the number of studies conducted with these species regarding propagation, fertilization, spacings and frequencies of cut and irrigation, little has been studied about the physiological aspects of both, especially in intercropping system.…”

Physiological and yield evaluation of perennial forage plants grown in intercropping in the semiarid region is indispensable in the search for higher efficiency of the agricultural and livestock production systems. In this context, an experiment was carried out at the Experimental Station of the National Institute of the Semiarid Region -INSA, in the municipality of Campina Grande, Paraíba, Brazil, to evaluate the physiological efficiency and yield of prickly pear and gliricidia in intercropping. Treatments were distributed in randomized blocks, with six replicates, being represented by four spacings between gliricidia plants: S1 (1.0 m), S2 (1.5 m), S3 (2.0 m) and S4 (3.0 m) x 2.30 m between rows. Prickly pear was planted in double rows of 1.5 m x 0.8 m x 0.5 m. The analyzed variables were initial, maximum and variable fluorescence chlorophyll a, variable/initial fluorescence ratio, potential quantum yield and the fresh matter yield of both crops. Density planting of gliricidia up to 4,348 plants ha -1 increases its photochemical efficiency and yield, but reduces light energy capture by prickly pear in intercropping, whereas its yield is not influenced by cultivation density. Regardless of gliricidia density, prickly pear yield was not influenced.

“…Outro aspecto adicional da gliricídia resulta na sua capacidade de fixar o nitrogênio atmosférico por ser uma leguminosa; confere bons níveis de produção de biomassa por consequência da queda do folheto e de excedente de raízes -mesmo diante de Decomposição da fitomassa de Gliricidia sepium em diferentes sistemas de ocupação da terra uma baixa disponibilidade hídrica. Por esse ângulo, quando empregado como adubo verde propicia melhorias na fertilidade natural dos solos por proporcionar aumento no aporte de material orgânico ao solo, uma vez que, também, aumenta o potencial produtivo (quando associado) das espécies agrícolas no sistema (PÉREZ-MARIN et al, 2018;CARVALHO et al, 2019).…”

Este estudo teve como objetivo avaliar a dinâmica da decomposição da fração foliar de Gliricidia sepium em diferentes sistemas de uso e manejo do solo. A pesquisa foi desenvolvida em três sistemas de uso da terra: sistema agroflorestal (SAF), mandala e pastagem. O método empregado para quantificar a decomposição da fitomassa foliar foi o de bolsas de nylon “litter bags”, coletadas a cada sete dias, por um período de 56 dias. Foram avaliados a massa remanescente (g), constante da decomposição (k) e o tempo de meia-vida (T½) do material foliar. O delineamento estatístico utilizado foi o inteiramente casualizado seguindo o esquema fatorial 3 × 8 (sistemas × períodos), com três repetições. Verificou-se efeito significativo isolado apenas para os períodos de avaliação. A taxa de decomposição variou entre 0,0087 e 0,0041 g g-1 dia e o T½ em 79 e 165 dias, uma vez que a curva de decomposição indicou que a perda da fitomassa foliar nos primeiros 20 dias de avaliação foi relativamente estável entre os sistemas. A taxa de decomposição e o tempo de meia-vida do material foliar foram mais expressivos no solo sob SAF. Palavras-chave: atividade microbiana; condições ambientais; serapilheira. Decomposition of Gliricidia sepium phytomass in different land occupation systems ABSTRACT: This study aimed to evaluate the dynamics of the decomposition of the leaf fraction of Gliricidia sepium in different land use and management systems. The research was developed in three land use systems: agroforestry system (AFS), mandala and pasture. The method used to quantify the decomposition of leaf phytomass was nylon bags “litter bags”, collected every seven days, for a period of 56 days. The remaining mass (g), constant of the decomposition (k) and the half-life (T½) of the leaf material were taken. The statistical design used was the randomized integer following the factorial scheme 3 × 8 (systems × periods), with three replications. There was a significant isolated effect only for the evaluation periods. The decomposition rate varied between 0.0087 and 0.0041 g g-1 day and the T½ in 79 and 165 days, since the decomposition curve indicated that the loss of leaf phytomass in the first 20 days of evaluation was relatively between systems. The decomposition rate and the half-life of the leaf material were more expressive in the soil under AFS. Keywords: microbial activity; environmental conditions; serapilheira.
