“…Perreira Júnior et al (2015), Coutinho et al (2014), Ndor et al (2012), Oliveira et al (2011), and Singh et al (2011) obtained gains in 100GW on cultivars of cowpea as P 2 O 5 doses increased.The variable NGP increased from 7.5 in the control to 12.0 at a dose of 120 kg of P 2 O 5 ha −1 , which represents an increase of 52.0% and indicates that adequate levels of phosphorus in the soil favor the reproductive efficiency per pod and hence production Coutinho et al (2014). andTeixeira et al (2016) obtained increases in NGP in cowpea and response to increases in phosphorus availability.…”

In tropical and semi-arid regions of Brazil, phosphorus is one of the most limiting elements of cowpea productivity. The aim of this study was to assess the effects of applying five phosphorus doses in the soil on morpho-physiological and production components in three improved cultivars of cowpea. The experiment was carried out at the São Fernando farm located in José de Freitas, PI, Brazil, in a Plinthosol with a low phosphorus content. The experimental design was complete randomized block design with four replications in a 5 × 3 factorial scheme consisting of five phosphorus doses (0, 60, 120, 180, and 240 kg P2O5 ha−1) and three improved cowpea cultivars (BRS Guariba, BRS Tumucumaque, and BRS Cauamé). No interaction was observed between cultivars and phosphorus doses for any of the assessed variables. The cultivar BRS Tumucumaque showed the highest value for one-hundred-grain weight (21.0 g) and, together with BRS Guariba, the highest value of pod length. An increment was observed in growth (stem diameter, main branch length, leaf area, and shoot dry matter) and production characteristics (number of pods per plant, number of grains per pod, one-hundred-grain weight, and grain production per plant) in response to increases in phosphorus doses. The dose of 183.1 kg P2O5 ha−1 provided the maximum technical grain yield, estimated at 2,023.3 kg ha−1.

“…In this sense, the residual phosphorus effect in the soil has been evaluated by several authors in common bean as a function of soil pH [7], in a degraded pasture area [3], and in other crops such as sugarcane [8]. Due to the need for information regarding the use of previous phosphatic fertilizers on successive crops in soils in the East of the state of Maranhao, the present study aimed to evaluate the residual effect of phosphate fertilization applied to maize cultivation on the successor crop, cowpea, in Cerrado of Maranhao region.…”

Phosphate fertilizers when applied to the soil, besides being harvested by the crops, promote a residual effect that can be offered to subsequent crops. The objective of this research was to evaluate the residual effect of phosphate fertilization applied to maize cultivation on the successor crop, cowpea, in the Cerrado region in Maranhao. The research was carried out in the experimental area of Federal University of Maranhão (UFMA), located in the city of Chapadinha, MA (3˚44'30"S, 43˚21'37''W). The experimental design was in randomized blocks, with six treatments and four replications. The treatments were composed of the following residual P doses: 0, 60, 70, 80, 90, 100 kg·ha ) and a greater profit margin (US $326.26). Thus, it is feasible to grow cowpea in previously cultivated areas, in order to take advantage of residual phosphate fertilization.

“…Once degraded, there is interest in opening up new areas. As an alternative to pasture recovery, cereal planting is promoted in order to provide residual effect from the soil correction and fertilization for forage reestablishment and cost reduction (Teixeira et al, 2016).…”

To support rural extension activities for family farming in the western Amazon, we evaluated the production of Mombasa grass (Panicum maximum Jacq) as a function of phosphorus sources (single superphosphate and calcined bone meal) and rates (100, 200, and 400 kg ha -1 P2O5). The experimental design was a randomized complete block, in a 2x3+1 factorial scheme. The use of calcined bone meal yielded a dry matter (1.73 t ha -1 cutting -1 ) and a plant height (55 cm) higher than the control (1.03 t ha -1 cutting -1 and 35 cm, respectively). However, the values were lower than those obtained with single superphosphate (3.19 t ha -1 DM and 91 cm in height). Regarding the dry matter production in the experimental period (202 days, five cuttings), the calcined bone meal promoted 54% of the production obtained with the use of single superphosphate.Additional keywords: Nutrient cycling; Panicum maximum; phosphate solubility. ResumoA fim de apoiar ações de extensão rural para agricultura familiar na Amazônia Ocidental, avaliou-se a produção de Mombaça (Panicum maximum Jacq) em função de fontes de fósforo (superfosfato simples e farinha de ossos calcinada) e doses (100; 200 e 400 kg ha -1 de P2O5), em blocos casualizados, em esquema fatorial 2x3+1. O uso de farinha de ossos calcinada proporcionou produção de matéria seca (1,73 t ha -1 corte -1 ) e altura das plantas (55 cm) superiores aos da testemunha (1,03 t ha -1 corte -1 e 35 cm, respectivamente). Contudo, os valores foram inferiores aos obtidos com superfosfato simples (3,19 t ha -1 MS e 91 cm de altura). Em relação à produção de massa seca no período experimental (202 dias, cinco cortes), a farinha de ossos calcinada promoveu 54% da produção obtida com o uso de superfosfato simples.Palavras-chave adicionais: Ciclagem de nutrientes; Panicum maximum; solubilidade de fosfato.
