This article addresses the issue of whether the tomato agroindustry (TAI) has been an effective instrument in the reduction of rural poverty. The TAI is by far the most important agroindustry in Mexico in terms of exports and employment creation. Most of the laborers employed by the TAI in northwest Mexico are temporary migrants coming from poverty-stricken regions in southern Mexico. Condition...

The epidemiologic literature in the English language regarding intake of tomatoes and tomato-based products and blood lycopene (a compound derived predominantly from tomatoes) level in relation to the risk of various cancers was reviewed. Among 72 studies identified, 57 reported inverse associations between tomato intake or blood lycopene level and the risk of cancer at a defined anatomic site;...

In an experiment with tomato and cucumber transplants, light units equipped purpose-built LED arrays were compared HPS sodium lamps a power of 600 W voltage 230 V. For both the lamps, same PAR radiation level was used at plant height, which about 70–80 μmol/m2/s in conditions without daylight. The supplementary lighting carried out for 8 to 24 hours switched on during day when solar outside gre...

‘Big Beef’ tomatoes produced 2.68 kg/plant from a 72 day harvest period when they were grown in 0.35 liter aluminum beverage cans by a sub-irrigation hydroponic method. Tomatoes growing in net pots (70 ml) suspended by expanded polystyrene bead boards with a sub-irrigation method gave similar yields in one trial but lower yields in another trial than tomatoes growing in beverage cans. Tomatoes ...

the concentration of cu, mn, ni and zn were determined in tomatoes and onions samples using atomic absorption spectrometry. a total of 32 samples each of tomatoes and onions were collected from the exposed and control sites for analysis. the trace metals (cu, mn, ni and zn) concentration in tomatoes wee found to be 6.2406, 6.5521 , 5.7375 and 8.9297 mg/kg-1, respectively. while those of onions ...

The objective of this study was to evaluate the use of hyperspectral near-infrared (NIR) reflectance imaging techniques for detecting cuticle cracks on tomatoes. A hyperspectral NIR reflectance imaging system that analyzed the spectral region of 1000-1700 nm was used to obtain hyperspectral reflectance images of 224 tomatoes: 112 with and 112 without cracks along the stem-scar region. The hyper...

Consumption of tomato products has been associated with decreased risk of some cancer types, and the tomato antioxidant, lycopene, is thought to play an important role in the observed health effects. In this study, four carotenoids, trans-lycopene, phytofluene, phytoene, and zeta-carotene, were quantified in tomato products. Samples of raw tomatoes, tomato juice after hot break scalder, and fin...

The study was carried out during the 2018-2019 growing season under greenhouse conditions to determine population development and infestation rates of Thrips, Leafhopper species, Tuta absoluta damaging tomatoes in Karatay Meram (Konya) districts. For this purpose, 10 greenhouses tomato were selected from two Delta-type sexual pheromone trap, blue yellow sticky traps hung each greenhouse. placed...

in recent years, increased public awareness of the detriment of consuming common products, during whose production chemical fertilizers and pesticides are used, on the one hand, and also the benefits of organic farming for health and environment, on the other hand, have caused an increase in the demand for organic products. due to the yield loss in product in organic farming because of the lack...

Firmness is an important aspect of the quality of fresh tomatoes. Its measurement is necessary for quality control, as well as for postharvest studies to develop procedures for preparation and handling of fresh-cut tomato slices. This study had two objectives, to determine how initial ripeness and cutting affect the textural changes in tomato tissue during storage and to develop a method for me...
