It is well known that citrus plants that have been infected by Xylella fastidiosa display nutritional deficiencies, probably caused by production of extracellular polymers by the bacteria that block normal nutrient flow through the xylem. The aim of this work was to study the mineral composition of specific foliar areas in different stages of infection in citrus. Thus, the concentrations of mac...

In this paper we compute nutrient-expenditure elasticities for two macro nutrients (calories and protein) and five micro nutrients (calcium, thiamine, riboflavin, calcium and iron) using an all India sample of rural households for 1994. We show that in each case the respective elasticities are positive and significant. This lends support to our hypothesis that an increase in income would increa...

Understanding the impact of losing trophic diversity has global significance for managing ecosystems as well as important theoretical implications for community and ecosystem ecology. In several tropical forest ecosystems, habitat fragmentation has resulted in declines and local extinctions of mammalian and avian terrestrial insectivores. To assess the ability of a tropical rainforest community...

OBJECTIVE To evaluate the consumption of ultra-processed foods, its associated factors, and its influence on nutrient intake in young adults. METHODS In 2004-2005, the individuals belonging to the Pelotas birth cohort of 1982 were identified for a home interview. A total of 4,297 individuals were interviewed and 4,202 individuals were included in the study (follow-up rate of 77.4%). Diet was as...

Optimal feeding, including optimal micronutrient intake, becomes one of the ways to overcome the long-term consequences of undernutrition. Macronutrient and micronutrient intake were important to a rapid growth and development of young children. The study objective was to assess macro and micronutrient intake and its adequacy in children aged 12-23 months. This survey was a cross-sectional stud...

Sufficient nutrient application is one of the most important factors in producing quality citrus fruits. One of the main guides in planning citrus fertilizer programs is by directly monitoring the plant nutrient content. However, this requires analysis of a large number of leaf samples using expensive and time-consuming chemical techniques. Over the last 5 years, it has been demonstrated that i...

A field experiment was conducted at ARS, Bhavanisagar, during summer 2021, to investigate the effect of multi-nutrient-loaded electrospun PVA nanofibre on green gram. The developed from polyvinyl alcohol (10%) infused with macro and micronutrients. coated seeds recorded higher plant height (44.97 cm); crop growth rate (1.5- 18.43 g m-2 d-1); leaf area index (0.56-1.84 m2m-2) duration (13.29-34....

consumption of organic manures such as vermicompost and spent mushroom compost in a system based on organic agriculture beside to maintenance soil health improvement and yield of medicinal plant spearmint. therefore, an completely randomized design experiment with four replication on spearmint (mentha spicata l )was conducted in horticultural department of mohaghegh ardabili university. experim...

The fishing industry is deeply dependent on complex and high quality diets consisting of dry feed, vitamins and micro/macro-elements. The suitable dose of each essential nutrient is different based on the fish species, their age and physiological conditions. In this study, the effects of two recommended doses of riboflavin (20 and 30 mg vitamin per each kg dry feed) on growth, hematological and...
