1. 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

2. Productive potential of superior genotypes of Paspalum notatum Flügge in response to nitrogen fertilization
RESUMO O gênero Paspalum compõe as pastagens naturais das regiões tropicais e subtropicais da América com várias espécies de reconhecido potencial forrageiro. O objetivo deste estudo foi avaliar a influência de diferentes níveis de fertilização nitrogenada sobre os caracteres agronômicos e na eficiência de utilização de nitrogênio por genótip

3. Root-knot nematode, Meloidogyne javanica, in response to soil fertilization
Resumo Nematoides-das-galhas das raízes (RKNs) Meloidogyne spp. causam perdas consideráveis na produção de hortaliças em todo o mundo. Embora o uso de nematicidas químicos seja um dos principais meios de controle de RKNs, a dependência nesses nematicidas está associada aos altos custos e impactos negativos à saúde humana e ao meio ambiente. No pres

4. Nitrogen and Potassium Fertilization in the Initial Growth of Annona crassiflora Mart.
ABSTRACT Annona crassiflora Mart. presents medicinal and food potential, and is also used in the recovery of degraded areas, however, little is known about its nutritional requirements. The aim of this work was to analyze the initial growth of A. crassiflora submitted to nitrogen and potassium fertilization. The experiment was conducted with a complete rando

5. Crop Yield Responses to Sulfur Fertilization in Brazilian No-Till Soils: a Systematic Review
ABSTRACT Sulfur (S) fertilization recommendations for grain crops in Brazil were formerly established from studies on crops with a low yield potential grown on soils under conventional tillage (CT). However, the subsequent adoption of no-tillage (NT) altered S dynamics in the soil, making it necessary to carefully evaluate the applicability of these S fertil

6. Effect of previous soil management on sugarcane response to nitrogen fertilization
ABSTRACT: N Fertilizer recommendations must be improved to optimize N use efficiency (NUE) for bioenergy crops. A study was conducted to test the hypothesis that sites varying in historical usage of by-product differ in soil N-supplying power and sugarcane (Saccharum spp.) responsiveness to N fertilization. Our aim was to quantify soil N availability and N f

7. Performance of Flooded Rice Grown in Succession to Winter Cover Crops
ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase

8. Dosis de N sobre reflectancia espectral, contenido de clorofila y nutrientes en plantas de gerbera
ABSTRACT In soilless crop, nutritional management must ensure the concentration and balance of nutrients, in order to obtain high productivity and quality, while fine adjustment of fertilization contributes to reduce environmental impact. Under the assumption that (1) an optimum level of N can be determined for gerbera, which provides the maximum potential p

9. Coffee leaf analysis using DRIS from irrigated and non-irrigated plantations in the alto Paranaíba region / Diagnose foliar em cafeeiro de sequeiro e irrigado na região do alto Paranaíba com o uso do DRIS
Cerrado soils have low fertility and under-dosing of fertilizers leads to nutritional imbalance on coffee plantations. This study aimed to: comparatively characterize the main deficiencies, nutritional imbalances and excesses in the aerial part of coffee plant; indicate nutrients which respond well to fertilization and their synergistic and antagonistic inte

10. Resposta de forrageiras à diferentes doses de lodo de curtume de tecnologia limpa em condições controladas e a campo / Response of forage to different doses of sludge from tannery of "clean technology" under controlled conditions and field
Industrial processes generate waste such as sludge from tannery "clean technology" that can be used in agriculture, to increase the productivity and supply of nutrients to the soilplant system. On this basis it was aimed to assess the feasibility of using primary sludge from a tannery in clean technology in the fertilization of pasture grasses and forage leg

11. Predição da disponibilidade de nitrogênio e potencial de resposta à fertilização nitrogenada em plantações de Eucalipto / Prediction of nitrogen availability and response potential to nitrogen fertilization in eucalyptus plantations
Respostas à fertilização nitrogenada têm sido observadas apenas em condições de solo muito especiais, como nos Espodossolos e nos solos muito degradados. Contudo, considerando as altas taxas de exportação de N e o possível esgotamento das reservas de N orgânico potencialmente mineralizável, espera-se que as florestas manejadas intensivamente respo

12. Modulação da rede de trocas gasosas em um cultivar de cana-de-açúcar tolerante a seca: o papel do fósforo / Network modulation of leaf gas exchange in a drought tolerant sugarcane cultivar under water deficit: a role of Phosphorus
Drought is one of the main abiotic stresses causing significant reduction of crop yield in most of agricultural areas in tropical and subtropical regions. Particularly, water deficit is the major environmental factor limiting sugarcane yield. The objective of this study was to identify what kind of changes in the photosynthetic network would be linked to the
