Potassium management effects on yield and quality of cassava varieties in tropical sandy soils
(2022-01-01)
Potassium (K) fertilisation at planting time may not be sufficient to achieve high cassava yields. Experiments were conducted over two growing periods using sweet cassava (SC) variety IAC 576-70 and bitter cassava (BC) ...
Yield, Yield Components, Soil Chemical Properties, Plant Physiology, and Phosphorus Use Efficiency in Soybean Genotypes
(Taylor & Francis Inc, 2017-01-01)
Expansion of soybean [Glycine max (L.) Merrill] cultivated in Brazil to regions with low fertility soils gave rise to studies on the possibility of obtaining highly productive cultivars with high nutrient use efficiency. ...
Adequate plant densities to increase agricultural rice yield
(Univ Central Marta Abreu Las Villas, 2021-01-01)
The use of adequate plant densities can be a key and important factor to increasing rice productivity (Oryza sativa L.). Therefore, the objective of this study was to investigate the influence of four population densities ...
Cotton yield and fiber quality affected by row spacing and shading at different growth stages
(Elsevier B.V., 2015-04-01)
Carbohydrate production and reproductive structure development in cotton (Gossypium hirsutum) depends on light availability, a determinant of cotton yield. Light availability is decreased by cloud cover or self-shading ...
Spatial and temporal behavior of coffee rust in C. canephora and its effects on crop yield
(2021-01-01)
Coffee rust has been one of the main factors responsible for reducing crop yield. The management of this disease corresponds to one of the main costs in the production chain of C. canephora and often the practices adopted ...
ASIAN SOYBEAN RUST INTEGRATED MANAGEMENT POTENTIAL: DISEASE SEVERITY, PLANT DEVELOPMENT AND YIELD COMPONENTS, CULTIVAR MG/BR-46 (CONQUISTA)
(Univ Federal Uberlandia, 2014-06-01)
Soybean rust caused by Phakopsora pachyrhizi Sydow & P. Sydow is one of the major diseases of the soybean crop. The aim of this study was to evaluate the effects of sowing dates, plant populations and reduced doses of ...
Plant density and nitrogen fertilization in Swiss chard
(Assoc Brasileira Horticultura, 2012-10-01)
An experiment was conducted to evaluate the effect of plant spacing and nitrogen fertilization on Swiss chard's yield, from September to November 2009. The experimental design was of randomized blocks in split plot with ...
Soil—Plant Relationships in Soybean Cultivated under Conventional Tillage and Long-Term No-Tillage
(2022-03-01)
Soybeans [Glycine max (L.) Merrill] have great economic prominence in the world, and soil management systems can directly interfere with their yield through changes in soil physical-hydric properties. Thus, the aim of this ...
Agronomic optimal plant density for semiupright cowpea as a second crop in southeastern Brazil
(2020-09-01)
Cowpea [Vigna unguiculata (L.) Walp.] cultivars with high yield potential and suitable plant architecture for mechanized harvesting have recently shown a growing interest to be cultivated as a second crop in fall–winter ...
Inoculation with Plant Growth-Promoting Bacteria to Reduce Phosphate Fertilization Requirement and Enhance Technological Quality and Yield of Sugarcane
(2022-01-01)
Phosphorus (P) is a critical nutrient for high sugarcane yields throughout its cultivation cycles, however, a higher amount of P becomes rapidly unavailable to plants due to its adsorption to soil colloids. Some plant ...
