Melon Seedlings Phytomass under Poultry Litter Biochar Doses

Agricultural Sciences 2021年第3期12卷 181-197页

作者： Laysa Gabryella de Souza Laurentino Lúcia Helena Garófalo Chaves Antônio Ramos Cavalcante Jean Pereira Guimarães Felipe Guedes de Souza washington benevenuto de lima Hugo Orlando Carvallo Guerra Josely Dantas Fernandes department of Agricultural Engineering Federal University of Campina Grande (DEAG/UFCG) Campina Grande Brazil

The use of organic waste for the preparation of seedling substrates is an important environmental and economic option. In this perspective, substrates using biochar emerges as an alternative for seedling production due to their favorable physical and chemical characteristics. The present study aimed to evaluate the efficiency of doses of poultry litter biochar as a substrate constituent for the production and quality of the seedlings. The work was conducted in a semi protected environment, belonging to the Federal University of Campina Grande—UFCG. The statistical design used was completely randomized in a 6 × 2 factorial scheme, consisting of 6 doses of biochar (0, 4, 8, 12, 16 and 20 t∙ha−1) and two varieties of melon (Yellow and Hales Best Jumbo) with 4 repetitions totaling 48 experimental units. The fresh and dry plant phytomass mass (aerial, roots and total), root length and the quality of seedlings were evaluated. It was concluded that the addition of poultry litter biochar to the substrate was beneficial, promoting an increase in the analyzed seedling variables, being the ideal dose for good development of melon seedlings 12 t∙ha−1. The Yellow variety presented a better response than the Hales Best Jumbo to the charcoal application. Considering the advantages of the use of poultry litter biochar on the substrate composition, found in the present study, its utilization constitutes a viable alternative for the development of melon seedlings and for the environmental disposal of the poultry litter.

Agricultural Sciences 2019年第6期10卷 753-762页

作者： washington benevenuto de lima Antonio Ramos Cavalcante Benedito Ferreira Bonifácio André Alisson Rodrigues da Silva Luan Dantas de Oliveira Robson Fábio Alves de Souza Lúcia Helena Garófalo Chaves department of Agricultural Engineering Federal University of Campina Grande(DEAG/UFCG)Campina GrandeBrazil

The experiment was carried out in the greenhouse of the deAg/UFCG, Campina Grande (PB), Brazil, to evaluate the growth and development of the bell pepper subjected to fertilization with biochar and nitrogen. The experiment was conducted in pots under greenhouse conditions. Treatments were arranged in a completely randomized design, in 4 × 4 factorial scheme, relative to four doses of biochar (0;7;14 and 21 m3⋅ha−1) and four doses of nitrogen (0;40;80 and 120 kg⋅ha−1), with three replicates. Considering the analysis of growth of bell pepper plants during the first 45 DAS, is recommended the average dose of biochar of 19 m3⋅ha−1 on vegetable behavior. Under the conditions of the experiment, nitrogen favored only the absolute growth rate of plant height and the stem diameter.

Regulation of Pollen Foraging Activity in Apis mellifera Africanized Honeybees Colonies

Agricultural Sciences 2016年第6期7卷 335-340页

作者： Erica Gomes de lima Simone Cristina Camargo Pedro da Rosa Santos Jose washington Santos Oliveira Vagner de Alencar Arnaut de Toledo Universidade Estadual de Maringa Maringa Brazil Universidade Federal de Sergipe Sergipe Brazil departamento de Zootecnia Universidade Estadual de Maringa Maringa Brazil

Efficient honey production requires knowledge about the behavior of the workers and the parameters that influence the strength of the colony. In this study, the objective was to analyze the interaction between the foraging behavior of worker honeybees and pollen storage levels in Africanized honeybees colonies. Colonies with low pollen storage increased pollen intake rates, but this value was 15% lower than colonies with high pollen storage, demonstrating a direct relationship between the pollen storage levels and foraging activity. The difference in pollen intake rates varied according to the number of foraging honeybees and pollen load collected by each individual. Under both high and low pollen storage, colonies returned pollen storage to initial level within 16 days, suggesting that honeybees regulate pollen storage levels around a homeostatic set point. Relationship between pollen storage levels and colony brood production was also found, indicating how alterations in the behavior of each individual can affect the strength of the colony.

This paper proposes the use of the flexible tolerance method(FTM) modified with scaling of variables and hybridized with different unconstrained optimization methods to solve real constrained optimization *** benchmark problems used to analyze the performance of the methods were taken from G-Suite *** original method(FTM) and other four proposed methods:(i) FTM with scaling of variables(FTMS),(ii) FTMS hybridized with BFGS(FTMS-BFGS),(iii) FTMS hybridized with modified Powell's method(FTMS-Powell)and(iv) FTMS hybridized with PSO(FTMS-PSO), were implemented. The success rates of the methods were 80%,100%, 75%, 95% and 85%, for FTM, FTMS, FTMS-BFGS, FTMS-Powell and FTMS-PSO, respectively. Numerical experiments including real constrained problems indicated that FTMS gave the best performance, followed by FTMSPowell and FTMS-PSO. despite the inferior performance compared to FTMS and FTMS-Powell, the FTMS-PSO method presented some advantages since good different initial points could be obtained, which allow exploring different routes through the solution space and to escape from local optima. The proposed methods proved to be an effective way of improving the performance of the original FTM.

Objective: The present study aimed to investigate and to compare the electrophysiological changes in bipolar patients and healthy subjects during the execution of a saccade task. Materials and Methods: The subjects had to respond to a fixed visual stimulus presented by a LEDs bar. We executed an ANOVA (one-way) and post hoc Scheffé test to examine the difference of absolute alpha power and reaction time among four groups: control, depression, manic and euthymic. We observed the frontal, parietal and occipital regions. The paired t test was realized on each electrode and group to compare the pre and post moment in the task. Results: We observed a statistical difference among the groups for the behavioral variable—saccade reaction time. For the electrophysiological variable—absolute alpha power, we did not find significant difference between the moments (pre and post stimulus presentation) for none of the electrodes of each bipolar group. However, the results pointed out to a difference between the moments for F3, P3, O1 and O2 electrodes for control group. Conclusion: We cannot affirm that the task influences the cortical activity of the patients. It is possible that the method used to analyze the data is not the adequate. The time-frequency analysis could be better to analyze the present data. We also observed that the absolute alpha power could be considered a marker of bipolar disorder, but not of the different states (i.e., mania, depression, euthymia).
