“…However, in biological fixation of N, Fabaceae need high quantities of phosphorus to meet the needs of the nodules (Caldas et al, 2009). Thus, in the treatments in which there is a greater number of dwarf pigeon pea plants, greater competition for P may have occurred, which could explain the lower DOP indices for phosphorus as the Fabaceae population increased (Table 3).…”

Intercropping is a technique which consists of cultivating two or more species in the same area. In these systems, planning and management should be carried out in order to avoid interspecies competition for water, light, and nutrients. This paper aimed to evaluate macronutrient content and accumulations in corn (Zea mays L.) intercropped with dwarf pigeon pea (Cajanus cajan L.) in different plant arrangements. The experimental design adopted was one of randomized blocks, with six treatments and four repetitions. The treatments consisted of different arrangements of dwarf pigeon pea intercropped with corn: corn in monoculture, dwarf pigeon pea sown in the same rows as the corn, one row of dwarf pigeon pea sown between the rows of corn, dwarf pigeon pea sown in the same rows and in a row between the corn, and dwarf pigeon pea sown in the same rows and in two rows between the corn. The following variables were evaluated: dry matter (t ha ). The arrangement with dwarf pigeon pea sown in the same rows and in two rows between the corn increased N content in the corn plants, in relation to the other arrangements and the corn in monoculture. Ca content and accumulations were higher in corn in monoculture and in the arrangement with dwarf pigeon peas sown in the same rows as the corn.

“…Studies with the application of phosphate fertilization in Mimosa caesalpiniifolia were conducted in sites implanted in Caatinga, but no significant effects of the use of this nutrient on the plant were found. This was justified by the low mobility of phosphorus in the soil and the fact that fertilization was localized, which may have induced competition for the nutrient, because neighboring plants did not receive fertilization, and may have been strong competitors (Caldas et al, 2009).…”

“…The works with Mimosa caesalpiniifolia focused on the evaluation of quality and nutrition in seedling production (Costa Filho et al, 2013;Melo et al, 2018), fertilization when in Caatinga sites (Caldas et al, 2009), and the measurement of burlap production (Ferreira et al, 2007;Freire et al, 2010), but did not test the phosphorus supply when installing Mimosa caesalpiniifolia alley cropping.…”

The use of fertilizers can increase the production of Forest species, which can be used for the extraction of wood in monocultures or in agroforestry systems. Thus, the objective was to evaluate the application of phosphorus doses in the implantation of Mimosa caesalpiniaefolia in a degraded area. The experimental design was a randomized complete block design with four blocks, with treatments at the following doses: 0, 12.5, 25.0, 50.0 and 100.0 g plant -1 of P 2 O 5 (source: triple superphosphate), whose quantities used were folded the following year and applied in the projection of the crown. The variables measured were biometric attributes (height, stem diameter in base and in breast height), biomass, nutrient accumulation (whole plant) and soil fertility. There was an increase in height and diameter of the plant, biomass, accumulation of phosphorus in the plant and increase of phosphorus concentrations in the soil. The application of 29 g of P 2 O 5 in the pit and after implantation, it is recommended to apply 47 g of P 2 O 5 per plant in the projection of saplings seedlings in low phosphorus soils, after first year.

“…Os teores de nitrogênio tiveram menores oscilações no período da estiagem. Caldas et al (2009) relataram que as oscilações podem ter decorrido da dificuldade de transporte de nutrientes para a planta em períodos de estiagem, diminuindo o teor de nitrogênio, e que a possível maior contribuição de nitrogênio atmosférico fixado no período chuvoso pode ter contribuído para aumentar o teor observado na parte aérea da planta. Assim, oscilações na parte viva da planta ocasionam mudanças no teor de nutrientes da serrapilheira depositada.…”

Objetivou-se avaliar a deposição e composição química de componentes da serrapilheira existente e depositada em um bosque de sabiá (Mimosa caesalpiniifolia Benth). O experimento foi realizado durante o período de agosto de 2006 a julho de 2007. A avaliação da serrapilheira existente e depositada foi realizada a cada 28 dias utilizando-se 20 quadrados de 1 m², alocados aleatoriamente, escolheno novas áreas a cada avaliação. O bosque apresentou plantas com diâmetro média na altura do peito de 26,8 cm. A deposição mensal de matéria orgânica de folhas e ramos no período experimental foi de 15.167 e 3.373 kg/ha, respectivamente, e aumentou no período de maior precipitação, numa relação de 0,30 com o acúmulo, o indica acúmulo maior que a deposição. A proporção de folhas foi de 87% do total da serrapilheira, com médias de 2,9% de nitrogênio e 0,17% de fósforo. A relação carbono/nitrogênio das folhas ficou abaixo de 30, enquanto a de ramos, entre 30 e 40, comprovando melhor qualidade das folhas. Durante o período experimental, a deposição de nitrogênio via serrapilheira foi de aproximadamente 462 kg/ha e a de fósforo, 30 kg/ha. A deposição de serrapilheira é essencial para manutenção da fertilidade do solo em bosques de sabiá e contribui para sua conservação e sustentabilidade.
