Última Aplicação de enxofre em cobertura e qualidade fisiológica de sementes de feijão - DOI: 10.4025/actasciagron.v30i5.5968 Agronomy César, Mônica Lúcia; UNESP; Fonseca, Nara Rosseti; UNESP; Toledo, Mariana Zampar; UNESP; Soratto, Rogerio Peres; UNESP; Cavariani, Cláudio; UNESP; Crusciol, Carlos Alexandre Costa; UNESP. A qualidade fisiológica das sementes pode ser afetada pelo estado nutricional das plantas, destacando-se, dentre os nutrientes, o fornecimento de enxofre, constituinte essencial dos aminoácidos. O trabalho objetivou avaliar os efeitos da adubação sulfatada em cobertura sobre a qualidade fisiológica de sementes de feijão cv. Pérola. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições. Os tratamentos foram constituídos por cinco doses de enxofre (0, 20, 40, 60 e 80 kg há-1) em cobertura, na forma de sulfato de amônio, 22 dias após a emergência das plântulas. Avaliou-se a qualidade fisiológica das sementes logo após a colheita mediante testes de germinação e vigor. A aplicação de enxofre, em cobertura, aumentou o vigor das...

Ano: 2008 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/5968 Canola response to nitrogen sources and split application AGRIAMBI Kaefer,João E.; Richart,Alfredo; Nozaki,Márcia de H.; Daga,Jacir; Campagnolo,Rodrigo; Follmann,Paulo E.. ABSTRACTThe aim of this study was to evaluate the response of the canola crop to nitrogen (N) sources and split application. The experiment was carried out in two agricultural years (2009 and 2010), at the experimental unit of the Pontifical Catholic University of Paraná - PUCPR, Campus of Toledo. A completely randomized design in 5 x 2 factorial scheme was adopted in the experiment. The treatments consisted of five split applications of N at sowing and/or as top dressing (0 and 0, 120 and 0, 0 and 120, 40 and 80, 80 and 40 kg of N ha-1) and two N sources (ammonium sulfate and urea), with four replicates. The canola genotype Hyola 61 was used in the experiment, which was evaluated for plant height, number of plants m-2, shoot dry matter, leaf area, mass of...

Even though the major benefit of arbuscular mycorrhizae is the increased uptake of phosphate from the soil solution and translocation to the plant, changes in the activity of enzymes involved in nitrogen (N) metabolism have been detected in mycorrhizal roots. Using differential display of reverse-transcripts of tobacco roots not-inoculated or inoculated with Glomus intraradices (Gi), we have cloned two partial cDNAs (NtGi2 and NtGi3). The presence of a conserved CobW/HypB/UreG domain and phylogenetic analyses suggest that NtGi2 and NtGi3 encode isoforms of urease accessory protein G (ureG) highly similar to ureG from fungi. The steady state levels of the putative ureG transcripts were shown to be higher in roots colonized by Gi, as compared to...

The feasibility and increase in the production of new cultivars can be obtained with the practice of nitrogen fertilization. The objective of this study was to verify the effect of sources and levels of nitrogen fertilization, concerning the depths, on the percentage of mycorrhizal colonization and soil fertility when covered by Brachiaria brizantha cv. Xaraés. A randomized blocks design was used and the treatments were under a 3 x 4 factorial scheme, regarding three nitrogen sources (urea, ammonium sulfate, and ajifer-L40) and 4 nitrogen levels (0, 100, 200 and 400 kg ha-1), studied at 2 different depths (0-0.10 and 0.10-0.20 m), with 3 replications.

Agrociencia Islam,Muhammad; Mohsan,Saleem; Ali,Safdar. Nitrogen fxing capacity of leguminous plants can be increased by the supply of adequate amounts of nutrients, especially phosphorus and sulfur. Some nutrients have direct involvement in the process of nitrogen fixation while others afect by improving growth of host plant. Field experiments were conducted at two different locations in northern rainfed Punjab, Pakistan, to assess the amount of nitrogen fixation and nitrogen uptake by chickpea (Cicer arietinum L.) during crop growing seasons 2006-2007 and 2007-2008. Treatments were: phosphorus levels (0, 40 and 80 kg P2O5 ha-1); sulfur sources (gypsum and ammonium sulfate) and levels (0, 15 and 30 kg S ha-1).

The objective of present study was to examine the effect of molasses and ammonium sulfate concentration on intracellular lipid accumulation by Trichosporon asahii. Nine culture media with different concentration of molasses (M,%) and ammonium sulfate (N,g/l) includings M8N0.5, M8N1.0, M8N1.5, M12N0.5, M12N1.0, M12N1.5, M16N0.5, M16N1.0 and M16N1.5 were randomly assigned in completely randomized design (CRD). Five milliliter of inoculums was transferred in 45 ml of media and incubated at 30oC with shaking at 160 rpm for 6 days. Results illustrated that lipid content was higher when T. asahii was cultured in the medium M12N0.5.

Zootec. Pedroso,André de Faria; Rodrigues,Armando de Andrade; Barioni Júnior,Waldomiro; Souza,Gilberto Batista de. The objective of this trial was to evaluate chemical additives and a bacterial inoculant on the inhibition of alcoholic fermentation and reduction of losses in sugarcane silages. Treatments were (doses on a fresh forage basis): without additive (control); urea (10 g/kg); urea (5 g/kg) + sodium benzoate (0.5 g/kg); sodium benzoate (1 g/kg); urea + ammonium sulfate in a 9:1 relation (10 g/kg); Lactobacillus buchneri (5 × 10(4) cfu/g). Silages were produced in 10.16- × 30-cm PVC tubes, provided with tight lids adapted with Bunsen valves for gas losses quantification. Minisilos were opened 139 days after ensiling. Ethanol content (227 g/kg dry matter - DM) and total DM loss (30%) were high in the control silage. All additives, except benzoate, decreased...

Ano: 2011 URL: http://periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/3946 Nitrogen doses and weed control via intercropping with gliricidia for corn production Planta Daninha Silva,P.S.L.; Braga,J.D.; Ribeiro,M.S.S.; Oliveira,O.F.; Santos,T.S.. Many studies have demonstrated the beneficial influence of nitrogen doses on corn dry grain yield and green ear yield. Due to a growing concern with environmental degradation, many agricultural practices, adopted in the past, are being reexamined. With regard to weed control, strategies that employ mechanical control, including intercrops, are being the object of renewed interest. The purpose of this study was to evaluate the effects of the application of nitrogen doses (0, 40, 80, and 120 kg N ha-1; as ammonium sulfate) and weed control on the growth, green ear yield, and grain yield of the AG 1051 corn cultivar. A randomized block experimental design with split-plots and nine replications was adopted. In addition to nitrogen rates, the AG 1051 cultivar...

ABSTRACT Agricultural intensification to improve wheat yield has increased the demand for nitrogen fertilizers. This study aimed to investigate the wheat response in succession to soybean due to application of nitrogen rates and sources in top dressing, as well as to determine the N rates of maximum technical yield (MTY) and maximum economic yield (MEY). A field experiment was carried out in Ponta Grossa, Paraná State, Brazil, on a clayey Typic Hapludox (Oxisol) under a continuous no-till. A randomized block design was used, with 3 replications in a 4 × 3 complete factorial arrangement. The treatments consisted of a control and 3 N rates at 40; 80 and 120 kg∙ha−1 as calcium nitrate (CN), ammonium sulfate (AS), and urea (UR) in top dressing at tillering of...

ABSTRACT The aim of this study was to evaluate the influence of nitrogen (N) fertilization, environment and cultivars on the protein concentration, sodium dodecyl sulfate sedimentation test (SDSS) volume and falling number in wheat. The experimental design was a randomized blocks in split plot scheme with four repetions. Four wheat genotypes were evaluated under six N managements in four enviroment (subplots). The wheat genotypes evaluated were IPR Catuara TM, BRS Gaivota, Quartzo and CD 120. Protein concentration, SDS sedimentation test, falling number and grain yield were evaluated. Combined analysis of variance for the four environment was performed and means were compared by Tukey test at p ≤ 0.05. The environmental effect is greater than the genotype...
