Conilon, which were cultivated in two producing regions to identify the most stable and productive genotypes. The experiment was a randomized block design with three replications and seven plants per plot, carried out in the south of Bahia and the north of Espírito Santo, environments with different climatic conditions, and evaluated during four harvests. The proposed Bayesian methodology was implemented in R language, using the MCMCglmm package. This approach made it possible to find great genetic divergence between the materials, and detect significant effects for both genotype, environment, and year, but the hyper-parametrized models (block effect) presented problems of singularity and convergence. It was also possible to detect a few differences between crops within the same environment. With a model with lower residual, it was possible to recommend the most productive genotypes for...

On this basis, this study was conducted to evaluate the genetic diversity of Coffea canephora genotypes using multivariate statistical procedures applied to a set of morpho-agronomic variables. The materials employed in this study constitute a crop located in Vila Valério - ES, Brazil, where the genotypes are arranged in a randomized-blocks experimental design with four replicates. Significant differences were detected by the F test at the 1% or 5% probability levels among the genotypes for all evaluated traits, demonstrating heterogeneity of genetic constitution in the studied population, which is favorable to breeding, as it indicates the possibility to identify superior and divergent individuals. Based on the generalized Mahalanobis distance, the most divergent combinations were obtained between genotype...

O trabalho teve como objetivo avaliar os atributos físicos do solo em diferentes tipos de manejo do solo no norte do Espírito Santo. O experimento foi realizado em Jaguaré - ES. Avaliou-se a densidade do solo, densidade de partículas, volume total de poros, macro e microporosidade e resistência do solo a penetração nas profundidades de 0 a 10 e de 10 a 20 cm em áreas de seringueira em monocultivo, pastagem em monocultivo, sistema silvipastoril (de seringueira com pastagem) e fragmento de mata atlântica. Os atributos físicos do solo variaram em função das profundidades e das áreas avaliadas. O sistema silvipastoril apresentou menor densidade do solo, menor resistência à penetração e maior microporosidade que o cultivo de pastagem em monocultivo, indicando um efeito positivo no consórcio de pastagem e seringueira.

Todavia, apresenta problemas com a aplicacao na superficie do solo devido as perdas de N por volatilizacao de amonia, decorrentes da acao da enzima urease. Objetivou-se determinar as perdas de N por volatilizacao de amonia de ureias protegidas e a produtividade de plantas de cafeeiro adubadas com tais fertilizantes. O experimento foi instalado em Nova Venecia – ES, em lavoura comercial de cafe Conilon ‘Vitoria INCAPER8142’. Foram avaliadas cinco fontes de fertilizantes nitrogenados: T1= Ureia comum (45 % N); T2= Ureia (45 % N) + NBPT; T3= ureia (44,6 % N) +0,15% de Cu + 0,4 % de B; T4= ureia (37 % N) + enxofre (17 %); e T5= nitrato de amonio (34 % N). Foram instalados coletores de amonia, em cada parcela experimental, imediatamente apos a aplicacao dos fertilizantes. As ureias protegidas pelo inibidor NBPT e pelos micronutrientes Cu + B apresentam as menores perdas por volati...

Sendo assim, objetivo deste trabalho foi verificar a existencia de diversidade genetica para a concentracao foliar de nutrientes em genotipos promissores de cafe Conilon no norte do estado do Espirito Santo, utilizando as analises estatistica multivariada. O delineamento utilizado foi o de blocos cazualizados com tres repeticoes, avaliando 42 genotipos. O estudo da diversidade genetica foi realizado pelo agrupamento dos genotipos pelo metodo hierarquico (UPGMA).

The state of Espirito Santo is the second largest brazilian producer of C. arabica and in 2014 produced 2.86 million of benefit bags. The experiment aimed to evaluate the leaf area, specific weight and dry weight four C. arabica genotypes and C. canephora genotype propagated by seeds and was conducted in irrigated farming in the Vila Valerio - ES. Four samples were taken, from October 2014 to January 2015, in the middle third region of the plant. The leaves were dried, weighed and measured the length of the midrib and the maximum width of the leaf blade. The Conilon coffee propagated by seed presents averages above average genotype V 785 -15, which received the lowest average for all studied traits and genotypes IAC V - 81 V and 19-08 showed intermediate behavior for the characteristics.

Important factors include the container and the form of propagation. The objective of this study was to evaluate the influence of two substrates and container volumes on the emergence and formation of Physalis peruviana L. mini-stumps. This study was carried out from September to November 2019, in a greenhouse belonging to the Federal University Network of the Holy Spirit. The design used was completely randomized, in a factorial scheme with the combination of three containers (R1 = tube with a volume of 50 ml; R2 = tube with a volume of 280 ml and R3 = plastic cups with a volume of 500 ml) and two substrates (S1 = Bioplant® and S2 = Provaso® + soil 1:1), totaling six treatments, four replications, six plants per experimental unit and 144 plants. After 90 days of experiment, it is recommended for a better emergence and emission of the shoots of Physalis peruviana L. the use of the volume of 280 ml,...

A especie Coffea Canephora L. apresenta potencial produtivo elevado, entretanto tal produtividade e dependente principalmente da fertilidade do solo, em especial do elemento nitrogenio. Deste modo, objetivouse comparar as perdas por volatilizacao de diferentes adubos nitrogenados no cultivo do cafeeiro Conilon. Foram avaliadas no experimento cinco fontes de adubos nitrogenados: T1= ureia perolada comum (45% N); T2= Ureia (45% N) + NBPT; T3= ureia (44,6% N) + 0,15% de Cu2+ e 0,4% de B; T4= ureia (37% N) + enxofre (17%) e T5= nitrato de amonio (34% N).
