Farmers' Soil–Water Management Practices and Perspectives on Soil Salinization in Mirab Abaya District, Gamo Zone, Southern Ethiopia

Irrigation and Drainage, EarlyView.
ABSTRACT Soil salinization is a critical threat, impacting 20% of the world's irrigated lands and jeopardizing food security. In Ethiopia's Mirab Abaya district of the Gamo Zone, unsustainable irrigation methods exacerbate this issue. This paper examines local farmers' soil–water management systems and their awareness of salinization, aiming to educate

Mutations in Lettuce Improvement [PDF]

International Journal of Plant Genomics, 2011
Lettuce is a major vegetable in western countries. Mutations generated genetic variations and played an important role in the domestication of the crop. Many traits derived from natural and induced mutations, such as dwarfing, early flowering, male sterility, and chlorophyll deficiency, are useful in physiological and genetic studies. Mutants were also

Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Nutrient composition and heavy metal accumulation in water hyacinth [Eichhornia crassipes (Mart.) Solms] and water lettuce (Pistia stratiotes L.) from the Dande River, Nepal: Implications for use as alternative feed resources

JSFA reports, EarlyView.
Abstract Background The proliferation of invasive aquatic macrophytes poses a significant ecological challenge globally, while many tropical regions face chronic shortages of affordable livestock feed. This study addresses this dual problem by assessing two invasive species, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes ...

Effect of different light‐emitting diodes on vegetative cannabis growth and antioxidant activity

JSFA reports, EarlyView.
Abstract Background Cannabis stands as one of the world's oldest plant sources for food and textile fiber. The study aimed to assess the impact of white LED (blue; 446 nm + amber; 595 nm + red; 653 nm), wide PC amber (595 nm), narrow amber (595 nm) + royal blue (430 nm) (NA + RB), and narrow amber (595 nm) + royal blue (430 nm) + cyan blue (485 nm) (NA

Molybdenum Deficiency in Lettuce [PDF]

Nature, 1952
MOLYBDENUM deficiency in lettuce has been reported by Brenchley and Warington1 for water-culture experiments. In Australia, Wilson2 has shown that a response in growth was obtained in the field by applying a solution of sodium molybdate to the foliage of chlorotic lettuces.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Human Norovirus Histo-Blood Group Antigen (HBGA) Binding Sites Mediate the Virus Specific Interactions with Lettuce Carbohydrates

Viruses, 2019
Lettuce is often implicated in human norovirus (HuNoV) foodborne outbreaks. We identified H-like histo-blood group antigens (HBGAs) on lettuce leaves as specific binding moieties for virus-like particles (VLPs) of HuNoV GII.4/HS194/2009 strain.
