Dry matter decomposition of cover crops in no-tillage cotton system. No-tillage cotton systems require soil coverage with cover crop residue for a longer time due to the late cycle of cotton. However, decomposition rates may vary between cover crops, and the adjustment... ... Repositório: BDPA Ano de publicação: 2018
Soybean macronutrient availability and yield as affected by tillage system. The effect of tillage system (NT-no tillage; CT-conventional tillage; MT-minimum tillage; and NT/scarification, every three years) on soybean nutrient availability and yield was evaluated on Oxisol af... ...

Soil chemical properties affected by cover crops under no-tillage system. The use of cover crops in no-tillage systems (NTS) can significantly improve the soil?s fertility. Thus, a study was performed to evaluate changes in chemical properties of soil caused by cover crops... ... Repositório: BDPA Ano de publicação: 2015
Economic viability of potassium fertilization in corn production on tropical soils under no-tillage system. This paper is therefore aimed at assessing the economic viability of different potassium (K) fertilizing practices in corn (maize) production under a no-tillage system.

Gypsum and phosphorus in the development of upland rice under a no-tillage system. The use of gypsum in a no-tillage system may be a feasible alternative for cultivating upland rice because of its ability to move some nutrients to greater depth in the soil and thereby stimulate root... ...

Evaluation of physiological traits in upland rice for adaptation to no-tillage system. In the cerrado region of Brazil, no-tillage is an alternative management practice to conserve soil and reduce cost of crop production. However, many studies have been showed that there is a decrease i... ... Repositório: BDPA Ano de publicação: 2009
Corn and soybean yields as affected by cover crops and herbicide timing under no-tillage system. To achieve better results in the no-tillage system (NTS), it is important to properly manage the cover crop prior to planting by using herbicides, usually glyphosate. The effect of glyphosate on plant... ... Repositório: BDPA Ano de publicação: 2013
Broadcast fertilizer rate impacts common bean grain yield in a no-tillage system. Increasing fertilizer rates at sowing can provide significant increases in grain yield in vegetable crops. However, very high rates can impair root development because of increased soil salinization i... ... Repositório: BDPA Ano de publicação: 2015
Nitrogen recovery from fertilizers and cover crops by maize crop under no-tillage system. Crop rotation associated with the use of cover crops promotes the introduction of crop residues to the soil, with direct and indirect effects on theavailability of plant nutrients, especially nitrogen... ...
