Cover crop effects on soils and subsequent crops in the pampas: A meta-analysis
(Elsevier Science, 2017-07)
Cover crops are a valuable management option for reducing soil erosion and nitrogen losses from agroecosystems. They improve soil quality but the impacts on crop yield depend on the type of cover crop, the commercial crop ...
Weed communities respond to changes in the diversity of crop sequence composition and double cropping
(Wiley Blackwell Publishing, Inc, 2017-06)
Agricultural intensification, besides increasing land productivity, also affects weed communities. We studied weed shifts in cropping sequences differing in the identity and number of crops grown. We also evaluated whether ...
Root growth and nutrient accumulation in cover crops as affected by soil compaction
Crop rotation using cover crops with vigorous root systems may be a tool to manage soils with some degree of compaction. Root and shoot growth as well as nutrient accumulation by summer species suitable for crop rotation ...
Evaluation of tropical legume cover crops for copper use efficiency.
(American Journal of Plant Sciences, v. 5, n. 9, p. 1236-1247, Apr. 2014., 2014)
The no-tillage system and cover crops-Alternatives to increase upland rice yields
Upland rice (Oryza sativa L.) cultivation has been increasing in importance in Asia while water availability for irrigation has been decreasing because of rapid growth in industry and urban centers. Therefore, the development ...
Cover crop termination timing on rice crop production in a no-till system
Measuring shikimic acid accumulation in response to glyphosate applications can be a rapid and accurate way to quantify and predict glyphosate-induced damage to sensitive plants. The objective of this paper was to evaluate ...
Soil organic matter in crop rotations under no-till
(Elsevier B.V., 2016-01-01)
Soil organic matter conservation, paramount in tropical agriculture, is affected by the composition of cultivated plant species and the input of dry matter and nitrogen into the system. However, SUM development in tropical ...
Cotton development and yield according to nitrogen application and cover crops
(Universidade Estadual de Londrina (UEL), 2011-01-01)
Nitrogen application on the cover and the maintenance of straw, conducted by direct seeding, should meet the needs of agriculture and promote soil conservation. This study evaluates the effect of pre-sowing nitrogen ...
