Bioavailability of Nutrients in Seeds from Tropical and Subtropical Soybean Varieties
(Taylor & Francis Inc, 2016-01-01)
The selection of varieties or species of plants with higher nutrient uptake efficiency and nutrient concentration for biofortification of food crops is a key tool to reduce malnutrition. Soybean (Glycine max L. Merr) is ...
Repartição de nutrientes nos ramos, folhas e flores do cafeeiro.

Unbiased approach to diagnose the nutrient status of red guava (Psidium guajava)
Fertilization of guava relies on soil and tissue testing. The interpretation of tissue test is currently conducted by comparing nutrient concentrations or dual ratios with critical values or ranges. The critical value ...
Nutrient resorption from senescing leaves in two Stipa species native to central Argentina
Nutrient resorption from senescing leaves enables plants to conserve and reuse nutrients. As such, it could be expected that plant species adapted to infertile soils have a higher nutrient resorption efficiency (percentage ...
Dinámica de la absorción y partición de nutrientes en Soja
(Fundación Rómulo Raggio, 2000-12)
Dynamics of nutrient uptake and partition in soybean (Glycine max (L.) Merrill) fertilization requires detailed information for the optimization of nutrient management. Sound economic and environmental nutrient management ...
Native and alien herbaceous plants in the Brazilian Cerrado are (co-)limited by different nutrients
Background and aims: The diverse flora of the Brazilian Cerrado is threatened by agricultural expansion, nutrient enrichment and invasion of alien plants. We performed a fertilization experiment to investigate the nature ...
Phosphorus and potassium balance in a corn-soybean rotation under no-till and chiseling
Nutrient use efficiency has become an important issue in agriculture, and crop rotations with deep vigorous rooted cover crops under no till may be an important tool in increasing nutrient conservation in agricultural ...
Comportamento diferencial de dois cultivares de feijoeiro (Phaseolus vulgaris L.) no acumulo de matéria seca, nutrientes, alumínio e eficiência nutricional.
(Anais da ESALQ, v.41, p.433-447, 1984., 1984)
Acumulo de materia seca e de nutrientes em milho cultivado no periodo inverno-primavera.
