Beans cultivation and water regime on soil physical attributes CIGR Journal
Domingues, Rafael; Pereira, André Belmont; Pires, Luiz Fernando; Schiebelbein, Luis Miguel; Barbosa, Eduardo Augusto Agnellos; Auler, André Carlos.
Beans crop is an agricultural staple largely consumed in Brazil because it is part of the basic food of the population. Such a crop is usually grown by small growers and turns out to be of a great social and economical importance. The aim of the current manuscript was to scrutinize the effect of soil water status on its physical attributes, such as bulk density, total porosity, macroporosity, microporosity, hydraulic conductivity under protected environment conditions on beans crop (Phaseolus vulgaris L.). The effect of the soil physical attributes on the biological response of the plants was also investigated. The experiment was installed in March of 2016 in a greenhouse. The experimental design was completely randomized in a factorial scheme with four...

BIOLOGICAL RESPONSEVINESS OF BEANS UNDER DIFFERENT SOIL WATER REGIMES AT PROTECTED ENVIRONMENT CONDITIONS IN SOUTHERN BRAZIL CIGR Journal
Domingues, Rafael; Pereira, André Belmont; Schiebelbein, Luis Miguel; Rosa, Jadir Aparecido; Barbosa, Eduardo Augusto Agnellos; Pires, Luiz Fernando.
Climatic conditions and soil water requirement notably impinge upon agriculture in such a way as to galvanize scientists to come up with advanced research in order to assure a more sustainable production at a given site. Under protected environmental conditions water is the main factor to be controlled aiming at maximization of yield and grade of agricultural products. The productive potential of a crop is extremely conditioned by the local atmospheric conditions along with requirements for water and nutrients in the soil. The aim of the current work was to scrutinize the effect of soil water status on the ecophysiological parameters and yield components of two cultivars of beans (Phaseolus vulgaris L.) under tropical climatic conditions. The experiment...

Weed control methods effect on the hydraulic attributes of a Latosol Agronomy
Pires, Luiz Fernando; Araujo-Junior, Cezar Francisco; Piccolomini Dias, Nivea Maria; Dias Junior, Moacir de Souza; Alcântara, Elifas Nunes de.
 Weed management plays a key role in the minimization of soil physical degradation processes such as compaction and hydric erosion. Different weed control managements can induce distinct changes in soil structure. One important soil physical attribute used for the analysis of modifications in soil structure is the soil water retention curve (SWRC). The objective of this work was to verify the use of physico-hydrical attributes to understand the effect of weed control managements on soil structure. Two soil layers (0–0.05 and 0.10–0.15 m) and six weed control managements divided into two groups were analyzed: I. no soil disturbance and ground cover (no weed control, post-emergence herbicide, mechanical mower); and II. soil disturbance and no ground cover...
