1. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

2. Effect on Merlot red wine of fining agents mixture: application of the simplex centroid design
Abstract In the elaboration of young red wine, it is necessary to obtain a clear product with stable color. The clarity and stability can be obtained using fining agents. The objective of this study was to evaluate the combined effect of fining with pea protein isolate (PPI), bentonite, and polyvinylpyrrolidone (PVPP) on a red wine, using the experimental de

3. Strategies of chemical management for weed control in cassava
ABSTRACT The use of strategies such as sequential applications and mixtures may increase the control spectrum and the residual effect of chemical control of weed in the cassava crop. Thus, the objective was to evaluate the selectivity and efficacy of sequential applications and tank mixture of herbicides in the control of weed in the cassava crop cultivar �

5. Experimental investigation on shear resistance of self-consolidating concrete beams
Resumo O concreto autoadensável se destaca pela alta fluidez e estabilidade, sendo estas propriedades obtidas com a redução da granulometria e volume de agregado graúdo da mistura, adição de materiais finos e a utilização de aditivos superplastificantes e modificadores de viscosidade. Um programa experimental foi realizado para avaliar a influência

6. Development of Geopolymers for Catalyst Support Applications
A geopolymer with high specific surface area was synthesized from metakaolin, amorphous silica and KOH, in the absence of foaming or saponification agents. The mixture modelling technique was selected for this study among the Design of Experiments tools, using surface area and total pores volume as response variables. The Si/K = 2.46 and Si/Al = 1.37 ratios

7. Spondias rootstock in the formation of seedlings of the yellow mombin
RESUMO O objetivo deste trabalho foi determinar o efeito de porta-enxertos de Spondias na formação de mudas enxertadas de cajazeira. O experimento foi instalado no Campo Experimental da Embrapa, em Pacajus-CE no delineamento inteiramente casualizado, com quatro tratamentos (porta-enxertos), cinco repetições e dez mudas/parcela. Os porta-enxertos de pé-f

9. Tank mixture of pesticides and foliar fertilizers for Triozoida limbata control in guava trees (Psidium guajava L.)
ABSTRACT Although tank mixture of pesticides and foliar fertilizers is common practice in agriculture, further clarification and scientific evidence is needed to support regulation. Thus, the objective of this work was to evaluate the effect of tank mixing an organosilicon adjuvant and manganese foliar fertilizer on the insecticide imidacloprid effectiveness

11. EXPERIMENT OF A SWING SEPARATING SIEVE ON A POTATO DIGGER
ABSTRACT For the purpose of achieving the distribution of the potato-soil mixture and the appropriate parameters of the swing separating sieve, we conducted experiments using the 4SW-170 potato digger. The experiments consisted of two parts. In each part, the experimental factors were crank rotational speed, sieve inclination and machine forward speed. The d
