Tomatoes are one of the most popular vegetables in the world, with over 7500 varieties available for consumers to purchase worldwide. Although it is easy to grow in your backyard, commercial production in the U.S. is based largely out of California. China leads the world in production, a just under 34 million tons/year. The U.S. comes in as the third largest producer, with roughly 11 million tons/year, California producing 96% of the processing crop and 1/3 of the fresh market produce, with states like Florida, Virginia, Georgia, Ohio, and Indiana making up the rest of the production. Tomatoes originated from South America and were likely first domesticated in Mexico, where a variety of colors, sizes, and shapes were developed. They were …show more content…
Fruit sold for processing are generally determinate, meaning they have a defined period of fruit development and then no longer produce. Some fresh market varieties are determinate, but indeterminate cultivars are common in smaller scale farms, as they allow for a longer harvest season. Because the tomato is self-pollinated, wind pollination is normally enough to ensure good fruit set. Temperatures between 65 and 80 are ideal for the highest quality and good fruit set.
There are many factors to think about when producing tomatoes. You want a friable soil that is well drained and moderately fertile, a sandy loam is ideal. The soil should be high in organic matter and crops should be rotated on a 3-year schedule with non-Solanaceaous plants to prevent pest problems. Plants are generally transplanted into plastic mulch to allow for an earlier crop and less weed problems in row. Transplants are spaced 18”-24” in row and 5’-6’ between rows. Rows should not be planted in valleys, as frost can easily kill tender transplants early in the season or destroy fruit quality

Tomatoes require intensive post-harvest handling to ensure fruit quality remains at the high level that consumers demand. Many problems can occur during this stage, from cooling failures, post-harvest disease issues and shipping damage. Bulk bins are taken to packing houses, where they are dumped into pits or water tanks. Jets of clean water propel the tomato along a belt into a dewatering belt. This dewatering belt contains soft bristles and cleans the field debris off the tomatoes. The fruit if then dried with jets of air, graded by color, size, and doe any defects. Some companies wax their tomatoes with edible food wax before shipping, but this is not always

    The best quality carrots are obtained when weather conditions favour regular uninterrupted growth. Plant growth is optimal between temperatures of 15° to 20°C, and the roots also develop the best colour and flavour at such temperatures. At temperatures below or above the optimum, poorer colour develops. The roots also tend to be shorter, often with a poor flavour, when high temperatures prevail. Insufficient soil moisture results in a longer and thinner root, while very wet conditions have the opposite effect and also give rise to a lighter colour.…

    All coffee producers should grow coffee under a canopy of other plants because shade cultivation is much safer and less detrimental to the environment. Shade cultivation also enhances the flavour of the coffee as less agrochemicals are used and it is the traditional way to grow it. Some trees should be left for migrating birds and the only trees that should be removed are ones that cause serious issues or problem for the coffee producers. Doing so will decrease soil erosion, salinity and degradation. It will also increase the biodiversity of the region because more animals will inhabit the plants and the plants filter water and air, storing carbon and restoring soil nutrients.…

Commercial insecticides, such as DDT, have shown to cause harm to many species and have the potential risk to run-off with rain and created unnecessary problems.

    Tomatoes are picked unripe and are stored into trucks that are, what Hawkins likes to refer to them as, a “fridge on wheels”. Since producers do not want the produce to ripen before they hit the shelves they are frozen. Then next step Hawkins states is, “Once the tomatoes arrive to their destination, they’re gassed with ethylene, which speeds up the ripening process to give off the illusion that the tomato is fresh” (www.spoonuniversity.com) Indeed the process lengthened the shelf-life of the produce but it is more of a negative than appositive thing. Many people would probably reconsider if they really knew the process to make convenient food actually ‘convenient’. People have a choice, either buy convenient produce that is bad for your health but is easily acquired or grow their own food that is worth the time it…

    Most of corn is genetically modified, and its produced more than any other crop in the US. In fact, “1 billion metric tons of the grain produced and more than 930 million tons consumed by livestock and people.” This information, coming from Monsanto, is followed by their claim that in the past twenty-five years, “production and consumption of corn has doubled from around 475 million tons in less than 25 years. Clearly, the world needs production to keep up with consumption”. Monsanto may think that they are doing their job to keep up with the country’s insatiable need for corn in its food, however doing so has extremely negative drawbacks. It completely jostles the necessary and delicate biodiversity of the ecosystem.…
