Upland rice under no-tillage preceded by crops for soil cover and nitrogen fertilization
(Revista Brasileira de Ciência do Solo, 2013-11-01) [Artigo]
The grain yield of upland rice under no-tillage has been unsatisfactory and one reason could be the nitrate/ammonium balance in the soil. Cover crops and nitrogen fertilization can be used to change the nitrate/ammonium ...
TRINEXAPAC-ETHYL AFFECTS GROWTH AND GAS EXCHANGE OF UPLAND RICE
(Revista Caatinga, 2016-01-01) [Artigo]
A major problem affecting some upland rice cultivars is the increase in plant size when subjected to high doses of nitrogen fertilizer, leading to high levels of lodging. A method to reduce the height of upland rice, and ...
Nitrate Reductase, Micronutrients and Upland Rice Development as Influenced by Soil pH and Nitrogen Sources
(Communications in Soil Science and Plant Analysis, 2017-12-16) [Artigo]
The average yield of upland rice under no-tillage system (NTS), a sustainable soil management, is lower than in conventional tillage (one plowing and two disking). One of the reasons given for this drop in crop grain yield ...
Atividade da enzima nitrato redutase em cultivares de arroz de terras altas
(Agrarian, 2014) [Artigo]
The cultivation of upland rice seems to be, among the major crops, the least adapted to the notillage system (NTS). One of the reasons attributed to this lower adaptation to NTS would be the low activity of the nitrate ...
Gas exchange rates, plant height, yield components, and productivity of upland rice as affected by plant regulators
(Pesquisa Agropecuária Brasileira, 2012-10-01) [Artigo]
O objetivo deste trabalho foi avaliar taxas de trocas gasosas, altura de plantas, componentes de produção e produtividade do arroz de terras altas, influenciados pelo tipo e pela época de aplicação de reguladores de ...
Leaf gas exchange and yield of three upland rice cultivars
(Bragantia, 2015-03-01) [Artigo]
Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L.) may support plant breeding programs. We evaluated the role of gas exchange rates and dry ...
