Fresh-market vegetable supplies have been sporadic following several December freezes in Florida, periods of cool, wet weather in coastal California, and several periods of subfreezing temperatures in California and Arizona. In addition, Mexican vegetables were damaged by a 2-day freeze in early February (extent of damage is unknown at this time). As a result, vegetable prices are now at or above the highs experienced a year earlier.

For some people organic agriculture is “farming without chemical fertilizers and pesticides”. This is short and concise, but misses important characteristics. Organic agriculture follows the logic of a living organism in which all elements (soil, plants, farm animals, insects, the farmer etc.) are closely linked with one other. Organic farming therefore must be based on a thorough understanding and clever management of these interactions and processes.
Tomate (Lycopersicon Esculetum Mill.) Cultivado en Invernadero Bajo Dos Regimenes Hídricos. Flujo de Savia, Crecimiento y Rendimiento
Para un cultivo de tomate protegido se establecieron dos tratamientos de riego, equivalentes a una reposición diaria de agua de 100% y 50% de la evaporación de bandeja (Evb), corregida por un factor de bandeja (Kb) y uno de cultivo (Kc). La diferenciación del riego y la medición del flujo de savia se iniciaron 34 días después del trasplante.

The botanical family Solanaceae includes several important vegetable crops such as tomatoes, potatoes, eggplants, and peppers. These crops share a number of insect and disease pests, so any crop rotation plan should consider all crops grown from this family.
Abscisic acid triggers whole-plant and fruit-specific mechanisms to increase fruit calcium uptake and prevent blossom end rot development in tomato fruit
Calcium (Ca) uptake into fruit and leaves is dependent on xylemic water movement, and hence presumably driven by transpiration and growth. High leaf transpiration is thought to restrict Ca movement to low-transpiring tomato fruit, which may increase fruit susceptibility to the Ca-deficiency disorder, blossom end rot (BER). The objective of this study was to analyse the effect of reduced leaf transpiration in abscisic acid (ABA)-treated plants on fruit and leaf Ca uptake and BER development.
El objetivo de la presente investigación fue comparar el rendimiento, productividad y tamaño de frutos con el manejo de plantas de jitomate cv. "Daniela" para formar doseles en forma de escalera (escaleriformes), con relación al que se obtiene con los sistemas comerciales de producción en doseles uniformes.
Tomatoes are susceptible to numerous diseases. This publication addresses wilt, nematode, and virus diseases.
- Fusarium and Verticillium wilt
- Walnut wilt
- Root knot nematode
- Virus diseases
Fresh market vegetable and melon production for the 24 selected crops estimated in 2010 totaled 435 million hundredweight, down 1 percent from last year. Harvested area covered 1.71 million acres, up slightly from 2009. Value of the 2010 crop is estimated at 11.2 billion dollars, up 3 percent from a year ago. The three largest crops, in terms of production, are onions, head lettuce, and watermelons, which combined to account for 38 percent of the total production.
The tomato is a very popular crop for production in greenhouses. Tomatoes are relatively easy to grow compared to cucumbers and lettuce, and yields can be very high. Demand for tomatoes is usually strong due to the vine-ripe nature and general overall high level of eating quality.
