Kachinski, Wagner Deckij; Ávila, Fabrício William; dos Reis, André Rodrigues [UNESP]; Muller, Marcelo Marques Lopes; Mendes, Marcelo CruzMade available in DSpace on 2022-04-28T19:51:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-05-01; Zinc (Zn) is an essential element for plants and mammals and its deficiency affects billions of people worldwide. This study aimed to evaluate the effects of soil Zn fertilization and foliar Zn sprays in different phenological stages of the plant on the grain nutritional quality of common bean (Phaseolu...
Selection of S3 progenies of forage maize based on topcrosses with different te...
Silva, Carlos Augusto da; Faria, Marcos Ventura; Paiva, Elida Auxiliadora Peralta; Zaluski, Welton Luiz; Gava, Emanuel; Marck, Diego Fernando DeMaize forage is commonly used as silage in milk and beef cattle livestock production systems. Despite the wide variety of maize hybrids with high potential for grain production, few available hybrids have been developed exclusively for forage aptitude. The present study aimed to select S3 maize progenies derived from the single hybrid AS1572 based on the combining ability of forage traits in topcrosses with tes...
Effect of co-inoculation of plant growth promoting bacteria on soybean crop
Pacentchuk, Fabiano; Gomes , Juliana Marcolino; Lima, Vanderlei Aparecido de; Mendes, Marcelo Cruz; Sandini, Itacir Eloi; Jadoski, Sidnei OsmarThe soybean crop often presents limitations on yield, many of which stem from nutritional problems, mainly due to insufficient supply of N. One of the ways to overcome this problem is through co-inoculation with plant growth promoting bacteria (PGPB), in order to potentiate the BNF and facilitate the acquisition of N and other nutrients in the soil. Thus, the aim of this study was to evaluate the effect of co-i...
Chemical parameters and ruminal disappearance of Secale cereale rye forage in d...
Heker Junior, Julio Cezar; Neumann, Mikael; Mendes, Marcelo Cruz; de Souza, André Martins; Santos, Leslei Caroline; Pereira e Silva, EmylliMade available in DSpace on 2020-12-12T01:38:40Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-10-01; The objective of the study was to evaluate the chemical parameters and the ruminal disappearance of dry matter of forage from the rye Secale cereale, cv. Temprano managed in different harvest regimes at the vegetative stage, with or without application of a fungicide based on Fluxapyroxade + Piraclostro...
Corn hybrid silage quality according to harvesting time
Neumann, Mikael; Venancio, Bruno José; Horst, Egon Henrique; Cristo, Fernando Braga; Petkowicz, Karina; Pontarolo, Giovanna Bobato; Mendes, Marcelo CruzThe present study aimed to evaluate the dry matter production of different corn hybrids, the plant chemical composition at the time of ensiling and the participation of the structural components of the plant at the different phenological stages. Corn hybrids P2530, P30B39H and P30R50H were harvested successively at the kernel blister (R2); kernel milk (R3); kernel dough (R4); and kernel dent (R5) stages. We det...
Export of N, P and K in barley subjected to fertilizer doses formulated with an...
Oliveira, Kathia Szeuczuk de; Mendes, Marcelo Cruz; Ilibrante, Gustavo Arruda; Antoniazzi, Noemir; Stadler, Alan Junior; Antoniazzi, Ana PaulaThe aim of this study was to evaluate the effect of nitrogen fertilization with and without humic acid in barley cultivars on the export of nitrogen, phosphorus and potassium grains. The experiment was performed in the city of Guarapuava, PR, during the 2015 and 2016 growing seasons. The experimental design was in RCB in factorial 5 x 2, with the following sowing fertilization (kg ha-1): 0, 100 NPK, 100 NPK+HS,...
Bromatological characteristics and ruminal digestibility of grain corn hybrids ...
Rossi, Evandrei Santos; Faria, Marcos Ventura; Mendes, Marcelo Cruz; Neumann, Mikael; Gabriel, Andre; Conte, Murilo Viotto DelO objetivo desta pesquisa foi avaliar a vitreosidade em híbridos comerciais de milho com grãos duros e dentados, e estudar o efeito desta característica no comportamento agronômico, valor nutricional e na degradabilidade ruminal dos grãos colhidos no ponto de silagem. Foram avaliados 12 híbridos comerciais de milho. Estes híbridos foram divididos em dois grupos (seis com grãos duros e seis com grãos dentados). ...
Nutritional composition of pre-dried silage of different winter cereals
Horst, Egon Henrique; Neumann, Mikael; Mareze, Juliana; Leão, Guilherme Fernando Mattos; Bumbieris Junior, Valter Harry; Mendes, Marcelo CruzThis study aimed to assess the chemical composition of the forage and pre-dried silage from twelve winter cereals harvested at pre-flowering. We used black oat (Avena strigosa) cv. EMB 139 and cv. IAPAR 61; white oat (Avena sativa) cv. IPR and 126 hp. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Triticum aestivum) cv. BRS Umbu and cv. BRS Tarumã; rye (Secale cereale) cv. Temprano a...
Bromatological characteristics and ruminal digestibility of grain corn hybrids ...
Rossi, Evandrei Santos; Faria, Marcos Ventura; Mendes, Marcelo Cruz; Neumann, Mikael; Gabriel, André; Del Conte, Murilo ViottoThe aim of this research was to evaluate vitreousness in commercial corn hybrids with flint and dent grains and to study the effect of this characteristic on agronomic behavior, nutritional value, and ruminal degradability of grains harvested in silage maturity. Twelve commercial corn hybrids were evaluated. They were divided in two groups (six with flint grains and six with dent grains). The experiments were c...
