his work aimed to evaluate the use of phosphorus (P) fertilizer, rhizobia inoculation, and seed enrichment with molybdenum (Mo) as tools for enhancing the cowpea yield in the Brazilian eastern Amazon. A set of field and greenhouse experiments were carried out in cerrado and upland forest environments. Four levels of P fertilization, eight rhizobia strains, and the application of mineral nitrogen (N) were evaluated for the cultivar BRS Tumucumaque (BR = Brasil e S = Sementes), and two levels of Mo seed enrichment were assessed for the cultivars BRS Tumucumaque and BRS Guariba. Grain yield increased linearly with the level of P applied. Inoculation with the rhizobia strain BR 3267 increased the shoot and nodule mass of the cultivar BRS Tumucumaque. There was no difference in grain yield and grain N accumulation between inoculation with seven rhizobia strains, N mineral fertilization and the control (without inoculation and N fertilization) in cerrado and upland forest environments. Cowpea grain yield and grain N accumulation were higher in the cerrado than in the upland forest environment and when the seeds were enriched with Mo. Phosphorus fertilization and seed enrichment with Mo are efficient tools to enhance cowpea yield in the Brazilian Amazon. |

ABSTRACT - The objective of this work was to evaluate the divergence among genotypes of Desmanthus sp. regarding morphological, productive, and qualitative characteristics, as well as to estimate the number of observations necessary to predict the real value of these characteristics. The experiment was conducted in the semiarid of the state of Pernambuco, Brazil, using 26 genotypes of Desmanthus sp. from different locations in the region. Seven evaluations were carried out from July 2013 to July 2014. Tocher?s grouping method and standardized average Euclidean distance were used. The coefficients of repeatability (r) and determination (R2) were estimated using two models of the analysis of variance, principal components based on the correlation or covariance matrix, and structural analysis based on the correlation matrix. The variables with the greatest weights were stem diameter, leaf area index, and forage yield, with frequencies of 22.05, 17.57, and 14.58%, respectively. Morphological, productive, and qualitative variability was observed among the genotypes of Desmanthus sp. All characteristics presented r and R2 of high magnitude in the methods of analysis. Up to four evaluation cycles are required to predict (R2=95%) the real value of stem diameter, peduncle length, plant height, leaf length and width, number of leaves, and pod length. RESUMO - O objetivo deste trabalho foi avaliar a divergência entre genótipos de Desmanthus sp. quanto a características morfológicas, produtiva e qualitativa, bem como estimar o número de observações necessárias para predizer o valor real destas características. O experimento foi conduzido no semiárido do estado de Pernambuco, Brasil, com uso de 26 genótipos de Desmanthus sp. de diferentes localidades nessa região. Foram realizadas sete avaliações de julho de 2013 a julho de 2014. Utilizou-se o método de agrupamento de Tocher e a distância euclidiana média padronizada. Os coeficientes de repetibilidade (r) e determinação (R2) foram estimados por dois modelos de análise de variância, componentes principais baseados na matriz de correlação ou covariância, e análise estrutural baseada na matriz de correlação. As variáveis com maiores pesos foram diâmetro do caule (DC), índice de área foliar e produção de forragem, com frequências de 22,05, 17,57 e 14,58%, respectivamente. Observou-se variabilidade morfológica, produtiva e qualitativa entre os genótipos de Desmanthus sp. Todas as características apresentaram r e R2 de alta magnitude nos métodos de análise. Até quatro ciclos de avaliação são necessários para prever (R2=95%) o valor real de diâmetro do caule, comprimento do pedúnculo, altura da planta, comprimento e largura da folha, número de folhas e comprimento da vagem.
