NUTRITIONAL STATUS AND DRY MASS PRODUCTION OF ALFALFA IN FUNCTION OF POTASSIUM RATES IN TWO SOILS
(Univ Federal Uberlandia, 2014-06-01)
Potassium fertilization is very important to alfalfa crop in terms of yield, quality and persistence of forage, especially on soils naturally poor K. Thus, to assess the effects of K fertilization in alfalfa production and ...
Near-isogenic wheat lines carrying altered function alleles of the Rht-1 genes exhibit differential responses to potassium deprivation
(Elsevier Ireland, 2012-04)
Most of the elements involved in the integration of signals of low external K+-supply into a physiological response pathway remain essentially unknown. The aim of this work was to study the influence exerted by DELLA ...
Potassium nutrition in sugar cane ratoons cultured in red latosol with a conservationist system
(2016-02-23)
The aim of this study was to evaluate the effect of potassium addition to the soil in first and second ratoon sugarcane cultures in a conservationist system. The experiment was conducted at the State of Sao Paulo, Brazil, ...
Growth and nutritional efficiency of watermelon plants grown under macronutrient deficiencies
(2019-04-01)
Biological damage caused by macronutrient deficiency in watermelon plants is still not known, and may lead to nutritional disorders and alterations in absorption and utilization efficiencies, depending on the evaluated ...
Symptoms of Macronutrients Deficiency in Sweet Pepper (Capsicum annuum L.)
(Univ Republica, Fac Agronomia, 2017-12-01)
This study aimed to describe the macronutrients deficiency symptoms and determine the leaf content of the nutrient in the appearance of the symptoms of deficiency in sweet pepper. The experiment was conducted in a greenhouse, ...
Contrasting effects of phosphorus and potassium deficiencies on leaf area development in maize
(Crop Science Society of America, 2018-09)
Management of P and K in agricultural systems is similar, since both move mainly by diffusion in soil. In maize (Zea mays L.), radiation capture is a consequence primarily of leaf area formation and senescence, but little ...
Nitric oxide and plant mineral nutrition: current knowledge
(Oxford University Press, 2019-03)
Plants under conditions of essential mineral deficiency trigger signaling mechanisms that involve common components. Among these components, nitric oxide (NO) has been identified as a key participant in responses to changes ...
NUTRITIONAL STATUS AND DRY MASS PRODUCTION OF ALFALFA IN FUNCTION OF POTASSIUM RATES IN TWO SOILS
(Univ Federal Uberlandia, 2015)
Prognosis of physiological disorders in physic nut to N, P, and K deficiency during initial growth
(2017-06-01)
The description of physiological disorders in physic nut plants deficient in nitrogen (N), phosphorus (P) and potassium (K) may help to predict nutritional imbalances before the appearance of visual symptoms and to guide ...
