This study aims to determine the effect of giving optimal concentration pineapple peel liquid organic fertilizer on growth and production red lettuce plants (Lactuca sativa var. Crispa)". research was conducted in Modong Village, Tulangan Subdistrict, Sidoarjo Regency continued at Agrotechnology Laboratory Muhammadiyah University. The from December 2022 January 2023. uses a Randomized Group Des...

Velvetbean (Mucuna spp.) is a summer annual that has been used as a cover crop to reduce erosion, fix nitrogen and suppress weeds and plant-parasitic nematodes. Crude aqueous extracts (1:15 dry weight plant/volume water) were made from velvetbean plant parts, and various concentrations of the extracts were evaluated in vitro for toxicities to different stages of Meloidogyne incognita (Kofoid an...

We compared photosynthesis and growth of Zea mays L (corn) and four weed species, Setaria viridis (L) Beauv (green foxtail), Echinochloa crus-galli (L) Beauv (barnyardgrass), Abutilon theophrasti Medic (velvetleaf), and Amaranthus retroflexus L (redroot pigweed), following foliar applications with atrazine, mesotrione, or a combination of atrazine and mesotrione in two greenhouse experiments. P...

Redroot pigweed is one of the injurious agricultural weeds on a worldwide basis. Understanding of its interference impact in crop field will provide useful information for weed control programs. The effects of redroot pigweed on cotton at densities of 0, 0.125, 0.25, 0.5, 1, 2, 4, and 8 plants m(-1) of row were evaluated in field experiments conducted in 2013 and 2014 at Institute of Cotton Res...

This paper reports the results of the first study of an aquaponic system for Pangasianodon hypophthalmus production that uses Lactuca sativa L. (lettuce) and Cichorium intybus L. rubifolium group (red chicory) intercropping in the hydroponic section. The experiment was conducted in a greenhouse at the Zurich University of Applied Sciences, Wädenswil, Switzerland, using nine small-scale aquaponi...

This study was conducted to investigate the effects of application Protaetia brevitarsis larvae manure (PM) on growth lettuce (Lactuca sativa L.) and red pepper (Capsicum annuum L.). Crops were planted in pots containing silt loam soils cultivated with basal chemical fertilizer at a standard rate (10.0 kg N 10a-1, 5.9 P2O5 6.5 K2O calcium carbonate 170 for 10.3 11.2 9.1 pepper) PM three rates (...

information of heavy metal toxicity about physiological aspect of lettuce is limited. therefore an experiment was conducted in crd designed with 7 replications on lettuce (lactuca sativa l.). treatments were cadmium in 3 concentration (0, 2 and 4 mg/l) added to hoagland solution. results were shown that increasing in cadmium of nutrient solution caused increasing in sod, pod antioxidant and pro...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

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...
