Sensibilidade de cultivares de algodoeiro ao cloreto de mepiquat
(Pesquisa Agropecuária Brasileira, 2009-10-01) [Artigo]
O objetivo deste trabalho foi avaliar a sensibilidade de cultivares de algodoeiro ao cloreto de mepiquat e verificar se ela está relacionada ao ciclo ou à arquitetura da planta. Foi realizado um experimento em casa de ...
Tratamento de sementes de soja com inseticidas e um bioestimulante
(Pesquisa Agropecuária Brasileira, 2008-10-01) [Artigo]
O objetivo deste trabalho foi avaliar o efeito do tratamento de sementes com inseticidas e um bioestimulante na germinação no crescimento da planta e raiz de soja. Foram realizados dois experimentos em delineamento de ...
Cotton root and shoot growth as affected by application of mepiquat chloride to cotton seeds
(Acta Scientiarum: Agronomy, 2012-03-01) [Artigo]
Estudou-se o efeito do tratamento de sementes de algodão com cloreto de mepiquat sobre o crescimento inicial de raízes e parte aérea. O experimento, realizado em casa de vegetação, utilizou vasos de PVC adaptados com uma ...
Microbial N-cycling gene abundance is affected by cover crop specie and development stage in an integrated cropping system
(Archives Of Microbiology, 2020-05-20) [Artigo]
Grasses of the Urochloa genus have been widely used in crop-livestock integration systems or as cover crops in no-till systems such as in rotation with maize. Some species of Urochloa have mechanisms to reduce nitrification. ...
Liming in the transition to no-till under a wheat-soybean rotation
(Soil & Tillage Research, 2007-12-01) [Artigo]
Soil and subsoil aluminium toxicity has been one of the main limiting factors for soybean and wheat yields in tropical soils. Usually liming is the most effective way to deal with soil acidity and Al toxicity, but in no-till ...
Are Reactive Rock Phosphate and Superphosphate Mixtures Suitable for No-Till Soybean?
(Agronomy Journal, 2014-07-01) [Artigo]
Several studies showed that rock phosphate efficiency may be increased when this fertilizer is mixed with soluble phosphates such as triple superphosphate (TSP), but most of these findings were obtained after 1 yr under ...
EFFICIENCY OF NITROGEN-FERTILIZATION IN SWEET SORGHUM
(Communications in Soil Science and Plant Analysis, 1985-01-01) [Artigo]
Phosphorus and potassium budget in the soil-plant system in crop rotations under no-till
(Soil and Tillage Research, 2013-01-01) [Artigo]
Soil management and crop rotations can affect P and K budget in soil, decreasing losses, and increasing fertilizer use efficiency. The P and K budget in the soil-plant system at depths up to 60. cm was studied for different ...
POTASSIUM ABSORPTION AND PARTITIONING IN COTTON AS AFFECTED BY PERIODS OF POTASSIUM-DEFICIENCY
(Journal of Plant Nutrition, 1991-01-01) [Artigo]
Cotton (Gossypium hirsutum var. Latifolium) was grown in nutrient media, at two K levels: 58.5 mg/K and 11.7 mg/K. Potassium deficiency (11.7 mg K/g of K) was imposed upon cotton plants at different stages of plant ...
Fungus incidence on peanut grains as affected by drying method and Ca nutrition
(Field Crops Research, 1997-05-01) [Artigo]
An experiment was conducted to study the effects of liming and drying method on Ca nutrition, fungus infection and aflatoxin production potential on peanut (Arachis hypogea) grains. Peanut cv. Botutatu was grown in the ...
