Cogongrass is a troublesome, invasive weedy species with reported allelopathic properties. The phytotoxicity of different constituents isolated from roots and aerial parts of this species was evaluated on garden lettuce and creeping bentgrass. No significant phytotoxic activity was detected in the methylene chloride, methanol, or water extracts when tested at 1.0 mg ml. However, the total essen...

Ready-to-eat baby-leaf vegetables market has been growing and offering to consumers convenient, healthy and appealing products, which may contain interesting bioactive compounds. In this work, the composition and the evolution of the phenolic compounds from different baby-leaf vegetables during refrigerated storage was studied. The phenolic compounds were extracted using pressurized liquid extr...

Hyptis suaveolens (Lamiaceae) is an exotic invasive plant in many countries. Earlier studies reported that the aqueous, methanol, and aqueous methanol extract of H. suaveolens and its residues have phytotoxic properties. However, to date, the phytotoxic substances of this plant have not been reported. Therefore, the objectives of this study were isolation and identification of phytotoxic substa...

The experiment was conducted during the year 2019-20 by Vegetable Section, Agriculture Research Station (ARS) Baffa Mansehra to compare garden soil with nitrogen (Urea) and potassium (Murate of Potash) for lettuce production in glass house. Lettuce is an important summer off-season high valued crop cultivated at District months July-August. produce transported other metropolises handsome earnin...

In the U.S., tomatoes are only exceeded by potatoes in economic importance. Among fresh vegetable products, annual per capita consumption of fresh tomatoes is only exceeded by lettuce and potatoes. Consumption of fresh tomatoes has remained fairly constant at around 12.8 pounds for the past 10 years as compared to the consumption of processed tomatoes in the form of ketchup and sauces which has...

Cadmium (Cd) is a non-essential trace element that accumulates in agricultural soils through the application of Cd-rich phosphate fertiliser. Vegetables can accumulate Cd to concentrations that sometimes exceed food safety standards. We investigated the potential of low-cost soil amendments to reduce Cd uptake by spinach (Spinacia oleracea L.), lettuce (Lactuca sativa L.) and onion (Allium cepa...

This study evaluated the essential and non-essential elements in lettuce cultivated on a rooftop urban garden metropolitan region of São Paulo. In addition, human health risks associated with potentially toxic metals based estimated daily intake (EDI), target hazard quotient (THQ), possible sources heavy metal contamination by multivariate statistical were analyzed. The lettuces contain macronu...

To many people slugs are unattractive and unwanted garden pests. Their extended eyestalks and slimy bodies are distinguishing characteristics. Slugs may be described as “snails without shells” or “mucus machines.” I like to think of them as “slimy thugs.” Their unwarranted attacks on defenseless crops can be excessively brutal and their footprints (slime trails) are always left at the crime sce...

This study aims to determine the effects of planting media and gutter slopes on growth lettuce (Lactuca sativa L.) using Nutrient Film Technique (NFT) in a hydroponic system. research was conducted at Experimental Garden Faculty Agriculture, Universitas Lakidende Unaaha, Konawe Regency, Indonesia, October 2021. The two treatments were arranged randomized block design (RBD) repeated three replic...
