Locomotion score and body condition shows a low relative contribution to the oc...
Luz , Gabriela Bueno; Barbosa , Antonio Amaral; Carvalho, Ivan Ricardo; Brauner , Cassio Cassal; Xavier , Eduardo Gularte; Schmitt , EduardoThis study aims to evaluate the occurrence and distribution of foot lesion and body condition scores to define which lesions are determinant for the manifestation of locomotion scores in dairy cows. A database from 482 Holstein cows was evaluated considering information on body condition scores (BCS), locomotion scores (LS), and cows with hoof lesions. Sole hemorrhage was the hoof lesion with the greatest occur...
Methods for estimation of genetic parameters in soybeans: an alternative to adj...
Carvalho, Ivan Ricardo; Silva, Jose Antônio Gonzalez da; Moura, Natã Balssan; Ferreira, Luiz Leonardo; Lautenchleger, Francine; Souza, Velci Queiróz deSelection practices are maximized when plant breeders have the availability of consolidated parameters, which will guide direct and indirect selection methods. This study aimed to apply a biometric alternative to minimize residual variance and maximize selection parameters by parent-progeny regression, interim controls, and mixed linear models intrinsic to breeding. The obtained data were subjected to the assum...
Effects of composted swine manure on nutrient content in grains of Panicum mili...
Muraro, Dionei Schmidt; Abrantes, Fabiana Lima; Basso, Claudir José; Abrantes, Fabio Lima [UNESP]; da Silva, Vanessa AlbaMade available in DSpace on 2021-06-25T10:23:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; The aim of this work was to evaluate the effect of different doses of composted swine manure on protein and macronutrient contents of proso millet grains and in nutrient export by the crop. The experiment was carried out in the years 2013 and 2014 in a randomized block design, with four replications and...
Soybean nutraceutical canonic inter-relations and its reflections on breeding
Carvalho, Ivan Ricardo; da Silva, José Antonio Gonzalez; Loro, Murilo Vieira; Sarturi, Marlon Vinícius Da Rosa; Hutra, Danieli JacoboskiIn recent years, questionings on the behavior of genotypes in different environments are frequent, especially those seeking to disclose the commercial and nutritional value of soybean genotypes. Consequently, this study – which is linked to the IRC Soybean Breeding Program located in Campos Borges, Rio Grande do Sul, Brazil – sought to analyze the physiological and nutritional aspects of S5 Soybean Segregating ...
Physiological marker of phosphorus nutritional status in potatoPhysiological ma...
Sausen, Darlene; Neis, Franciele Antônia; Uliana, Suzi Cerezer; Farias, Júlia Gomes; Hildebrand, Hilda Soriani; Mambrin, Ritieli BaptistaThe development of more efficient plants in the use of nutrients will be fundamental for agriculture in the coming years. The objective of this work was to define a physiological marker of the nutritional status of P for potato clones cultivated off-soil and in vitro, in order to facilitate the selection process of more efficient clones in the use of P. For this, two experiments were carried out with seven pota...
Spacing between rows of soybean genotypes: averages, regressions and correlatio...
Ferreira, Luiz Leonardo; Moreira, Natália Vilela; Carvalho, Ivan Ricardo; Santos, Núbia Sousa Carrijo dos; Fernandes, Marilaine de SáAverage tests and correlation analysis (simple, canonical and trail) allow the identification of characters correlated with grain yield. Due to the low availability of studies that report the levels of correlation between soybean plants and the spacing between rows and the demands of rural producers, the aim of this study was to identify the influence of the spacing between rows of soybean genotypes on yield le...
Use and response to phosphorus by potato clones in two cropping systems
Sausen, Darlene; Carvalho, Ivan Ricardo; Farias, Júlia Gomes; Dorneles, Athos Odin Severo; Pereira, Aline Soares; Mambrin, Ritieli BaptistaThe selection of potato plants (Solanum tuberosum L.) that are efficient in the use of phosphorus (P) plays an important role in increasing crop productivity, reducing the cost of production due to the high price of phosphate fertilizers, as well as reducing the pollution of the environment due to the better use of the applied fertilizers. The objective of this work was to compare the method of selection of pot...
Sowing density and clipping management: effects on the architecture and yield o...
Silva, Francielen Lima da; Carvalho, Ivan Ricardo; Barbosa, Maurício Horbach; Conte, Giordano Gelain; Hutra, Danieli Jacoboski; Moura, Natã BalssanThe dual-purpose wheat stands out as a complementary alternative for forage supply during the winter period. Therefore, this work had the objective of evaluate the performance characteristics in five genotypes of dual-purpose wheat submitted to different sowing densities and different clipping managements. The experiment was carried out during the 2016 and 2017 harvests. The experimental design was a randomized...
Physical purity of forage and granifer seeds in Brazil
Ternus, Ricardo; Meneghello, Geri Eduardo; Cavalcante, Jerffeson; Szareski, Vinícius Jardel; Carvalho, Ivan Ricardo; Martins, Andréa; Conte, GiordanoThis study aimed to evaluate the physical quality, identify and quantify the contaminants of seeds of forage and granifer species in the state of Santa Catarina, Brazil. The data collection was realized from the results obtained from samples of seeds lots collected by the State Program of Inspection, from the Input Inspection Division of the State Department of Vegetal Defense, Santa Catarina, Brazil. Batches o...
Length of soybean and corn seedlings influenced by seed vigor and size
Meneguzzo, Michele Renata Revers; Carvalho, Ivan Ricardo; Dellagustin, Simone Morgan; Xavier, Fernanda da Motta; Nadal, Ariele PaulaThis work had as objective to adjust the methodology of the seedling length test for soybean and maize seeds, depending on the level of vigor and size of the seed.Therefore, it was used soybean seeds of cultivar 5855 RSF IPRO (BMX ELITE) andhybrid maize seeds of the cultivar Fórmula Viptera , classified in two sizes of sieve and two levels of vigor for soybean and three levels for maize.A completely randomized ...
