1. COMPARAÇÃO DE MÉTODOS PARA DETERMINAÇÃO DE SUBSTÂNCIAS HÚMICAS EM FERTILIZANTES LÍQUIDOS COMERCIAIS
The beneficial effects of humic substances (HS) on crop development have been evidenced in the last decade, leading to the commercialization of HS products with fertilizing properties. Currently, three methods are frequently used for HS determination: method described in the manual of the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA); method

3. Effects of limestone and organic fertilizer on cassava yield and on chemical and physical soil properties
ABSTRACT Cassava has a high yield potential that can be achieved with adequate liming and fertilization of the soil. The objective of this study was to evaluate the effect of organic fertilizer application, in association or not with liming, on yield and morphological characteristics of cassava roots and on chemical and physical properties of the soil. The e

4. Association of Mechanical and Chemical Methods for Cotton Stalk Destruction
RESUMO: A destruição de soqueiras do algodoeiro após a colheita é uma medida profilática que visa reduzir a população de insetos-praga e de inóculos de doenças que podem permanecer alojados nos restos culturais e plantas de algodoeiro remanescentes. O objetivo deste trabalho foi avaliar métodos integrados de manejo das soqueiras, conciliando contro

5. Cauliflower Cultivars Associated with Urochloa decumbens Straw Mulch in Integrated Weed Management
RESUMO: No cultivo de hortaliças, a redução no uso de herbicidas tem sido um fator importante na definição do sistema de produção. O objetivo deste trabalho foi avaliar o desempenho produtivo de cultivares de couve-flor sobre palha de Urochloa decumbens, assim como o efeito da associação da palha e dos cultivares no manejo de plantas daninhas. Os tr

6. Efficacy and selectivity of alternative herbicides to glyphosate on maize
ABSTRACT The aim was to evaluate the selectivity and weed control of herbicides atrazine, nicosulfuron, mesotrione and tembotrione, applied alone and associated, in post-emergence of maize. Were carried out two experiments, one in the field in a randomized complete block design with four replications and eleven treatments, the second in greenhouse in a compl

7. Characterization of the Weed Flora in Rice Areas under Distinct Cropping Systems and Herbicide Managements
RESUMO: O objetivo deste trabalho foi avaliar a ocorrência de plantas daninhas em arroz irrigado por inundação, em função do sistema de plantio e do manejo de herbicidas na safra anterior. O experimento foi instalado em campo, em delineamento experimental de blocos casualizados dispostos em esquema fatorial 3 x 2, com oito repetições. O fator A foi o

8. Association mapping of drought tolerance indices in wheat: QTL-rich regions on chromosome 4A
ABSTRACT Drought is likely the main abiotic stress that affects wheat yield. The identification of drought-tolerant genotypes represents an effective way of dealing with the continuous decrease in water resources as well as the increase in world population. The aim of this study was to identify single nucleotide polymorphisms (SNP) associated with drought to

9. Biochar and mucuna increase papaya plant growth and nutrition, as well as soil fertility
RESUMO A associação de biochar a adubos verdes no cultivo de mamoeiro pode ser uma técnica de manejo promissora, principalmente em sua primeira fase de cultivo. Objetivou-se avaliar os efeitos de biochar e adubo verde (Mucuna aterrina) no crescimento e nutrição de mudas de Carica Papaya e na fertilidade do solo. O experimento foi conduzido em blocos cas

10. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

11. Biometric characteristics and canopy reflectance association for early-stage sugarcane biomass prediction
ABSTRACT: Knowing the spatial variability of sugarcane biomass in the early stages of development may help growers in their management decision-making. Proximal canopy sensing is a promising technology that can identify this variability but is limited to quantifying plant-specific parameters. In this study, we evaluated whether biometric variables integrated

12. Ammonium Glufosinate Associated with Post-Emergence Herbicides in Corn with the cp4-epsps and Pat Genes
RESUMO: Com a possibilidade do uso de amônio-glufosinate no milho, são fundamentais estudos com associações desse herbicida junto a outros. O objetivo do presente trabalho foi avaliar o controle de plantas daninhas e a seletividade de herbicidas em associação ao amônio-glufosinate em milho contendo os genes pat e cp4-epsps. O experimento foi realizado
