Root-system of peanuts as affected by phosphorus fertilization
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
There have been some responses of peanut roots to phosphorus. An experiment was carried out to study peanut root growth and distribution as related to P in the soil. The cultivars Tatu, Oira and Tup4 and the lines FCA 170 ...
Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Taylor & Francis Inc, 2005-01-01)
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
Ruzigrass root persistence and soybean root growth
(Springer, 2019-09-01)
Aims Cropping systems using forage grasses as cover crops have been effective in soil conservation and nutrient cycling, but root persistence of ruzigrass (Urochloa ruziziensis) is significant, and may impair root growth ...
Cotton root volume and root dry matter as function of high soil bulk density and soil water stress
(2008-12-01)
Soil compaction reduces root growth, affecting the yield, especially in the Southern Coastal Plain of the USA. Simulations of the root restricting layers in greenhouses are necessary to develop mechanisms which alleviate ...
Mechanical and biological approaches to alleviate soil compaction in tropical soils: assessed by root growth and activity (Rb uptake) of soybean and maize grown in rotation with cover crops
(Wiley-Blackwell, 2017-03-01)
Chiselling has been used to alleviate soil compaction but cover crops with deep, vigorous roots can improve root growth and activity of the cash crop for a longer time. The determination of root activity in addition to ...
Yield and nutritional requirements of cassava in response to potassium fertilizer in the second cycle
(2017-12-14)
Potassium (K) is one of the most absorbed nutrients by cassava because it acts on the synthesis and starch accumulation in the storage roots. Here, we show that K application at the beginning of the second vegetative cycle ...
Potassium supply to cotton roots as affected by potassium fertilization and liming.
(Pesquisa Agropecuária Brasileira, Brasília, v.38, nº 5, p. 635-641, maio 2003., 2011)
Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas
(2021-01-01)
Fire is a fundamental ecological factor in savannas because it affects vegetation dynamics and ecosystem functioning. However, the effects of fire on below-ground compartments, including biomass and root traits, and their ...
Histological events during in vitro rooting of Nothofagus nervosa (Fagaceae)
(Taylor & Francis, 2005-12)
In vitro rooting protocols were previously performed on Nothofagus nervosa to optimise the culture medium and environmental conditions. A qualitative and quantitative tissue differentiation study during adventitious rooting ...
Corn root length density and root diameter as affected by soil compaction and soil water content
(2007-01-01)
Negative effects of soil compaction have been recognized as one of the problems restricting the root system and consequently impairing yields, especially in the Southern Coastal Plain of the USA. Simulations of the root ...
