1. Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems
ABSTRACT The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions. The plots were composed of two cropping sys

2. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

3. Control of Italian ryegrass and Alexandergrass in corn using different corn sowing date, pre- and post-emergent herbicides
ABSTRACT Glyphosate-resistant (GR) Italian ryegrass (LOLMU) and Alexandergrass (URPLA) are troublesome weeds in corn cropping systems in Southern Brazil. The emergence pattern of those weeds is not uniform and may change according to the season’s environmental characteristics. Also, herbicide resistance has been diminishing the success of the weed control

4. Growth and yield parameters of white oat and wheat as affected by canola residues
ABSTRACT Despite being an important crop option for Brazilian agriculture, canola has some characteristics that may limit its insertion in some cropping systems, such as its allelopathic effects. Thus, the present work aimed to study the effect of canola crop residues on the seed germination, growth and grain yield of white oat and wheat plants. In laborator

5. Maize cropping systems and response of common bean in succession subjected to nitrogen fertilization1
RESUMO A sucessão de feijoeiro com culturas consorciadas, no sistema plantio direto, é benéfica, sobretudo na busca por sustentabilidade. Além da produção de palhada, o consórcio de culturas pode fornecer nitrogênio (N) ao feijoeiro em sucessão, diminuindo o uso de adubo mineral, que é poluente e tem custo elevado. Objetivou-se avaliar a resposta �

6. Summer Cover Crops Shoot Decomposition and Nitrogen Release in a No-Tilled Sandy Soil
ABSTRACT Cover crops have numerous benefits when used in a no-till system. Understanding the processes of decomposition and N release of summer cover crops (SCC) may help select species and management to be used in cropping systems. This study aimed to evaluate C and N loss of SCC shoots. Six SCCs were evaluated: velvet bean (Mucuna aterrima), pearl millet (

7. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

8. Chiseling and gypsum application affecting soil physical attributes, root growth and soybean yield
RESUMO O objetivo desse estudo foi avaliar o efeito da escarificação e da gessagem em atributos físicos do solo, crescimento de raízes e produtividade de grãos de soja. O experimento foi conduzido em Londrina, PR, em delineamento de blocos completos casualizados, com seis repetições. O solo da área experimental foi classificado como Latossolo Vermelh

9. Temporal stability of soil moisture in banana cropping area in the Brazilian semiarid region
RESUMO A umidade do solo é essencial para a produção agrícola. O conhecimento de sua variabilidade espaço-temporal é indispensável para suporte à agricultura, sendo fortemente influenciada pelas práticas culturais, condições de cobertura do solo e métodos de irrigação. Assim, este estudo teve como objetivo avaliar a estabilidade temporal e a di

11. Soil respiration dynamics in forage-based and cereal-based cropping systems in central Italy
ABSTRACT: Studies that have investigated soil carbon dynamics under Mediterranean conditions are scarce and fragmented and contrasting results have often been reported. This study aimed to fill some gaps in our knowledge by: (i) determining annual dynamics of total (RS) and heterotrophic (RH) soil respiration; (ii) estimating annual cumulative RS and RH; and

12. Crop systems and topdressing nitrogen on grain yield and technological attributes of common bean under no-tillage
RESUMO O feijoeiro tem sido a principal cultura em sucessão ao milho e à braquiária em sistema plantio direto, no Cerrado. Objetivou-se avaliar os efeitos de sistemas de cultivo e nitrogênio em cobertura na produtividade e atributos tecnológicos de feijoeiro sob plantio direto. Utilizou-se delineamento em blocos casualizados, em parcelas subdivididas, c
