“…The manganese content was high in single cultivation of black oat and black oat intercropped with vetch. These results differ from those observed by Teixeira et al (2008), who found no difference in the content of manganese in the single cultivation of Canavalia ensiformis, Cajanus cajan, pearl millet and their intercrops. As for sodium, the highest values were found in the intercropping.…”

RESUMO Biomass and nutrient cycling by winter cover cropsCover crops are of fundamental importance for the sustainability of the no-tillage system, to ensure soil coverage and to provide benefits for the subsequent crop. The objective of this study was to evaluate the production of biomass and the content and accumulation of nutrients by winter cover crops. The experimental design used in the experiment was a randomized complete block with four replications and six treatments: oilseed radish, vetch, black oats, vetch + black oats, vetch + oilseed radish and fallow. Black oat, oilseed radish in single cultivation and black oat + vetch and vetch + oilseed radish intercroppings showed higher dry matter production. Vetch + oilseed radish intercropping demonstrates higher performance regarding cycling of nutrients, with higher accumulations of N, P, K, Ca, Mg, S, Cu, Zn, Fe, Na and B.Culturas de cobertura são fundamentais para a sustentabilidade do sistema plantio direto por garantir a cobertura do solo e por proporcionar benefícios para a cultura subsequente. O presente trabalho teve o objetivo de avaliar a produção de biomassa, o teor e acúmulo de nutrientes por plantas de cobertura de inverno. O delineamento experimental foi o de blocos casualizados, com seis tratamentos: nabo forrageiro, ervilhaca, aveia preta, ervilhaca + aveia preta, ervilhaca + nabo forrageiro e pousio, com quatro repetições. O cultivo solteiro de aveia preta, nabo forrageiro e o consórcio de aveia preta + ervilhaca e ervilhaca + nabo forrageiro apresentam maior produção de matéria seca. O consórcio ervilhaca + nabo forrageiro demonstra desempenho superior quanto à ciclagem dos nutrientes, com maiores acúmulos de N,

“…It is possible that the organic matter from the dead plant cover practices provides a considerable availability of B in the soil. Elevated values of B, as an essential element for cell enlargement and differentiation and root growth, are commonly found in legume species used as cover plants, according to Teixeira et al (2008). A significant decrease was also found for Cl in live and dead plant cover data according to the ages of plantation (Figure 2-B).…”

ABSTRACT:The adoption of cover crops in commercial plantations has been shown to be an alternative to promote greater soil protection, enhancement in its structure and aggregation, optimization of accumulation and nutrient cycling to obtain greater production of biomass and higher nitrogen fixation. To determine the accumulation of micronutrients of Pueraria phaseoloides L., according to age, established as a soil cover in industrial oil palm crops, an experiment was carried out at Companhia Agroindustrial (CRAI) in the municipality of Tailândia, State of Pará, in an Oxisol. The experimental design was a randomized block with four replicates. The results allow to conclude that the accumulation of nutrients, except for Mn and Cu in the live Pueraria phaseoloides L. plant cover reduced over the years and those of B, Mn, Zn, and Cu were greater in the dead Pueraria phaseoloides L. plant cover and for Cl it was in the live Pueraria phaseoloides L. plant cover. The decreasing order of total micronutrient extraction was the following: Cl> Mn> B> Zn> Cu.

“…However, the subject has received much less attention than N, rendering it difficult to discuss, particularly because concentrations of P in green manure biomass are seldom informed in the literature dealing with the use of green manures. Both higher and lower concentrations have been reported (Blaise et al 2005a, Teixeira et al 2008).…”

Yam (Dioscorea cayennensis Lam.) is a promising crop for small growers in the Northeast of Brazil, but productivities are limited due to low fertilization rates. Green manure could be an alternative due to its low cost and high availability. However, there is little information available regarding the effects of green manures on the productivity of yam. The quality and yield of yam tubers, “da costa” variety, were evaluated under application of three different green manures and a control treatment: 1) yam intercropped with sunn hemp (Crotalaria juncea L.); 2) yam intercropped with pigeon pea (Cajanus cajan L.); 3) yam intercropped with a combination of sunn hemp and pigeon pea; and 4) conventional yam crop system. The experiment was laid out in a randomized block design, with four repetitions. The data was submitted to analysis of variance and averages compared by Tukey´s test at 5%. Percentage values were transformed into arc sen (x/100)0.5. Sunn hemp and the combination of sunn hemp with pigeon pea produced the highest green manure biomasses (3.8 and 3.6 t DM ha-1, respectively) versus 2.1 t ha-1 with the use of only pigeon pea. However, the N concentration was higher in pigeon pea than in sunn hemp (26 and 16 g kg-1). Intercropping with pigeon pea led to the highest yield for total tubers (33.1 t ha-1), for market quality (32.2 t ha-1) and standard exportation quality tubers (23.0 t ha-1).
