The nutritional program impacts all of these factors, but not in a favorably coordinated manner (Table 1). If the seedling is supplied with all of the fertilizer that it has the genetic potential to use (high rate), a totally useless plug will result. This shoot on this plug will grow too large for the surface area provided by the plug cell in which it is growing. One seedling will shade the ne...

Anadromous Pacific salmon (Oncorhynchus spp.) transport marine-derived nitrogen (MDN) to the rivers in which they reproduce. Isotopic analyses indicate that trees and shrubs near spawning streams derive -22-2492 of their foliar nitrogen (N) from spawning salmon. As a consequence of this nutrient subsidy, growth rates are significantly increased in Sitka spruce (Picea sitchensis) near spawning s...

Sugarcane is an essential crop in the Brazilian economy. The adoption of techniques acclimatization plants vitro contributes to success field. present work aims evaluate effect Azospirillum brasilense on sugarcane seedlings. experiment was conducted with six treatments and twelve replications. There were two control without inoculation, one N fertilization without, four A. (2.0x108 CFU) at diff...

In the semiarid region of Brazil, salts found in water used irrigation. The objective was to analyze influence foliar fertilization with nitrogen as a mitigation salt stress passion fruit seedlings. design randomized blocks, treatments generated from Box’s Central Composite matrix, five electrical conductivities irrigation (ECw) (0.50; 0.98; 2.15; 3.32; 3.80 dS m-1) and doses (0.0; 0.30; 1.15; ...

Despite a high nitrate uptake capacity, the nitrogen use efficiency (NUE) of oilseed rape is weak due to a relatively low N remobilization from vegetative (mostly leaves) to growing parts of the plant. Thus, this crop requires a high rate of N fertilization and leaves fall with a high N content. In order to reduce the rate of N fertilization and to improve the environmental impact of oilseed ra...

Two replicated site preparation studies were used to examine the effect of management on pine height and volume growth in the next rotation on Paleudults. Treatments included no tillage, flat disking, bedding, and fertilization. The first rotation of planted slash pine (pinus ellionii Engelm. var. dioftii) was measured for 15 yr on one site and 20 yr at the other, harvested, and replanted witho...

The impact of nitrogen (N) fertilization in the vineyard on vine productivity, fermentation, and wine sensory properties was compared to that winery N addition enological characters Chardonnay between 2016 2018. Five treatments, including no or (No N), diammonium phosphate (+DAP), organic (+Org soil (Soil foliage (Foliar N) were evaluated. Foliar treatment evaluated 2017 2018 only, while other ...

As a result of global warming related to the development industry and agriculture, proportion atmospheric carbon dioxide has increased, temperatures have risen unprecedented levels. result, heat stress, aridity, salinity in soil leading significant research focused on deterioration reduced agricultural productivity. Therefore, it is necessary provide means maintain crop Agricultural seeking nov...

The major plant nutrient magnesium (Mg) is involved in numerous physiological processes and its deficiency can severely reduce the yield and quality of crops. Since Mg availability in soil and uptake into the plant is often limited by unfavorable soil or climatic conditions, application of Mg onto leaves, the site with highest physiological Mg demand, might be a reasonable alternative fertiliza...
