The authors evaluated the effectiveness of ReJeX-iT@ AG-145, Mesurola, activated charcoal, lime, and fipronil to reduce homed lark damage to lettuce seeds and seedlings. In Experiment 1, homed larks consumed significantly more feed mixture (50:50 grains and lettuce seed) than untreated clay-coated lettuce seed in a three-day choice-test. In Experiment 2, where clay-coated lettuce seed was treat...

Cool season vegetables require adequate soil moisture to assure that maximum yield and quality are achieved. On California’s central coast, where the majority of cool produced in US, long-term overpumping irrigation water has reduced groundwater levels led environmental degradation. Two evapotranspiration (ET) based field trials were performed near Salinas CA (USA) determine if ET-based schedul...

Forty percentage of UK peatlands have been drained for agricultural use, which has caused serious peat wastage and associated greenhouse gas emissions (carbon dioxide (CO2) methane (CH4)). In this study, we evaluated potential trade-offs between water-table management practices minimizing emissions, while seeking to sustain romaine lettuce production: one the most economically relevant crop in ...

ABSTRACT Determining the amount of nutrients accumulated by crops is an important tool for defining order in which are taken up and required. However, vary depending on genetic characteristics cultivars, climatic conditions, fertilization, soil management systems. The aim this study was to evaluate influence irrigation strategies doses nitrogen (N) fertigation content accumulation macro micronu...

AIM To investigate bacteriological quality in organically grown leaf lettuce, including the presence of selected pathogenic bacteria, and to obtain information about organic lettuce production, including fertilizing regimes. METHODS AND RESULTS Altogether 179 samples of Norwegian organically grown lettuce were collected from 12 producers. Escherichia coli was isolated from 16 of the lettuce s...

Studies were conducted on the effect of controlled atmosphere storage as well as chemical pretreatments on the quality of lettuce as well as biochemical composition of lettuce leaves, Lactuca sativa L., cultivar "Great Lakes." In a CA of 2.5% CO2 and 2.57 02, the lettuce heads could be stored up to 75 days. Pre-storage treatments with microbeand s6nescenceinhibiting chemicale (Captan, Phaltan, ...

The integration of indoor vertical cultivation with a recirculating aquaculture system into an aquaponic has the potential to become one most effective sustainable production systems for fish and leafy vegetables. In this study, lettuce was produced on rafts in coupled recirculation plant factory under controlled environmental conditions. aims study were evaluate yield, mineral status, health-p...

Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercr...
