CARDOSO, J. A. F.; LIMA, A. M. N.; CUNHA, T. J. F.; RODRIGUES, M. S.; HERNANI, L. C.; CUNHA, J. C.; AMARAL, A. J. do; OLIVEIRA NETO, M. B. deAccelerated land use changes have been observed in Brazil. In Northeast, the Caatinga (native vegetation) has been replaced by fruit production, especially by mango and grapevine cultivation. Land use changes, tied to management techniques, can change the soil chemical and physical attributes. Thus, the present study aimed to evaluate the impact of irrigated mango cultivation in soil chemical and physical attri...

Replacement of fish meal by protein soybean concentrate in practical diets for ...
SOARES, M.; FRACALOSSI, D. M.; FREITAS, L. E. L. de; RODRIGUES, M. S.; REDIG, J. C.; MOURIÑO, J. L. P.; SEIFFERT, W. Q.; VIEIRA, F. do N.The objective of this work was to evaluate the performance of Litopenaeus vannamei fed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC), and daily water exchange (30%). Each tank was stocked with 37...

CARDOSO, J. A. F.; LIMA, A. M. N.; CUNHA, T. J. F.; RODRIGUES, M. S.; HERNANI, L. C.; AMARAL, A. J. do; OLIVEIRA NETO, M. B. deA utilização inadequada das terras tem ocasionado deterioração e esgotamento dos recursos naturais existentes, além da queda significativa da produção agrícola, em razão da piora da qualidade do solo. A remoção da vegetação natural para dar lugar a cultivos agrícolas muitas vezes manejados de forma inadequada resulta na desestruturação do solo, diminuição da disponibilidade de nutrientes e decomposição da matér...
Anthracnose resistance sources to be explored by the common bean breeding progr...
SOUZA, T. L. P. O.; WENDLAND, A.; RODRIGUES, M. S.; ALMEIDA, L. C. S.; CORREIA, F. R.; RODRIGUES, L. A.; PEREIRA, H. S.; FARIA, L. C.; MELO, L. C.The main goal of the present work was to evaluate common bean anthracnose resistance sources for disease reaction under greenhouse and field conditions. In addition, the tested genotypes were also screened with SCAR markers linked to R genes presented as useful for the breeding programs in Brazil.
