Machines used for harvesting corn have gradually become more complex and more expensive. These devices have revolutionized farming, allowing farmers to harvest vast tracks of land quickly with only a few employees. This speed has led to bigger and bigger farms, with many smaller farmers having to sell land, giving way to the march of technology. [图片]Corn Combine Combines, large machines that are used primarily to harvest corn on the stalk, are ideal for threshing and gathering corn stalks over a wide field. Some models are capable of separating usable parts from those that must be discarded. According to the website for the Environmental Protection Agency, many of these devices are self-propelled, meaning the machine has its own engine requiring a driver. Other types of combines must be towed or pushed by a tractor or other engine-baring piece of farm equipment. Combines are also among the most expensive pieces of farm equipment, with list prices generally over $300,000. Maize Sheller A maize sheller is another type of self-propelled corn harvesting machine. According to the website for the Food and Agricultural Organization of the United Nations, these devices are built of rows of three to six conveyors that harvest corn still on the stalk, strip the corn of its unusable components and spit them out through a cleaning sieve. The difference between this system and the combine is the maize sheller is specifically designed for corn and cannot be used with other smaller grain or row-style plants. Dry harvesting of corn generally occurs from October 7 through November 3, according to the EPA's website. [图片]Forage Harvester Forage harvesters are tractor-driven implements that chop and gather crops like corn without doing any of the separating like the other machines. These devices are quite powerful, with some using as much as 600 horsepower. Crops are usually harvested wet through September 1 and October 15 of each year when using this machine so as to promote the process known as ensiling, which is a form of crop preservation through anaerobic fermentation.

Growing your own popcorn does not mean that you will immediately have a movie snack on harvest day. Depending on the variety of popcorn, it will take between 85 and 120 days to mature, according to Mother Earth News. For the popcorn to pop, you must dry it to 13 to 14 percent moisture, according to Iowa State University Extension Office. This can be done either artificially or naturally, depending on your local climate conditions. Allow the popcorn cobs to remain on the stalk as long as possible until the kernels and husks appear dry, but pick the corn and dry it artificially if rain threatens. [图片]Air Dry Step 1 Remove the husks from the popcorn cobs, then place the cobs into mesh bags. Step 2 Hang the bags in a dry place, below 130 degrees Fahrenheit, for several weeks until the popcorn kernels appear shriveled. The amount of time will depend on the humidity levels in your climate. Step 3 Push several kernels off the cob with your thumb and pop them in a popcorn popper to test the moisture content. Shell the remaining popcorn cobs if the kernels pop properly, but leave the other cobs to continue drying if the popcorn does not pop or sticks to the inside of the popper. Step 4 Shell the dried popcorn kernels with a popcorn sheller or push the kernels off with your thumb. You can refrigerate the popcorn in an airtight container for up to 30 months. [图片]Oven Dry Step 1 Preheat the oven to 300 degrees Fahrenheit. Step 2 Remove the husks from the popcorn cobs. Push the kernels of corn off each cob with your thumb. Alternatively, use a popcorn sheller (available from farmer supply stores and via the Internet). Discard the cobs. Step 3 Arrange the popcorn kernels in a single layer in a large roasting pan, then place the pan in the oven. Turn down the oven to the lowest temperature setting. Step 4 Dry the popcorn for five hours. Stir it every hour. Step 5 Turn off the oven and leave the popcorn overnight. You can pop the the kernels right away or refrigerate it in an airtight container for up to 30 months.

The tomato (Solanum lycopersicum) is a summer vegetable in the nightshade family. All tomatoes fall into one of two categories: determinate or indeterminate. Determinate tomatoes only grow to a certain size and produce a certain number of fruits, depending on the variety. Indeterminate tomatoes continue to grow vines and produce fruit for as long as conditions are favorable. Regardless of the difference in growth patterns, all tomatoes must be fertilized and are susceptible to the same pests, disease and frost damage. [图片]Tomato Characteristics Tomatoes come in many shapes, sizes and colors. Tomato sizes are characterized by weight and fall into three categories: beefsteak, cherry and grape. Beefsteak tomatoes can grow quite large at over 16 ounces, while small grape tomatoes mature to as little as 2 ounces. Some tomatoes are perfectly round while others, like roma varieties, are long and narrow, similar to a pepper. Oxheart varieties are heart-shaped with a pointed blossom end. Tomato colors include a wide range from white to black. Red and pink are the most common options, but purple and black varieties have gained popularity, particularly in specialty markets. Other colors include yellow, orange, green and various colors of stripes. All tomato plants have green leaves and stems. Some small determinate patio varieties reach a maximum of 1- to 2-feet tall, while some indeterminate varieties can grow vines over 12-feet long in one growing season. Always read the plant description carefully before making a decision on variety. Watch for Spring Frosts Frost will kill a tomato plant, so have a plan in place in case there is a chance of a late spring frost after seedlings have been planted. Cut the bottom off milk jugs to create a mini-greenhouse to provide frost protection on a chilly late-spring night. Because tomatoes are generally grown as annuals throughout the U.S. -- though they can be grown as tender perennials in -- all fruits should be harvested before the first expected frost in the fall. [图片]Fertilization and Water Needs Tomatoes are heavy feeders. After transplanting young seedlings, apply 1 tablespoon of 10-10-10 granular fertilizer per plant. With a rake, work it into the top few inches of soil in a circle all the way around the plant, out to 1 foot from the stem. Do not go deep enough to damage plant roots. When the first tomatoes have reached the size of golf-balls, or reach half their mature size for smaller varieties, add 1 tablespoon of 10-10-10 fertilizer per plant again. Reapply fertilizer three weeks later, and again after another three weeks. Always water thoroughly after fertilizing and make sure fertilizer does not touch leaves or stems. Do not apply fertilizer to plants that are stressed due to drought or heat. Water plants any time the soil is dry 1-inch below the soil surface. Infrequent, thorough watering is better than frequent light watering because this allows water to reach plant roots more effectively. Support and Pruning Small, determinate tomato varieties can be sufficiently supported by tying the main stem to a stake or using a standard three-ring tomato cage. Larger indeterminate varieties require more significant support. Make a sturdy, long-lasting tomato cage out of concrete remesh, available in sheets from many home improvement stores. Determinate varieties should not be pruned unless they have damaged branches, which should be removed 1/4-inch from the main stem with sharp, sterilized pruning shears -- sterilize tools with an alcohol wipe between cuts to prevent the spread of disease. Indeterminate varieties benefit from some pruning, especially if they outgrow their supports. Remove overgrown branches as needed to prevent broken stems due to fruit that is too heavy to support. Managing Pests Aphids are tiny white or green insects that cover leaves, stems and blooms. Knock aphids off of tomato plants with a shot of water from a hose. If a severe infestation occurs, spray ready-to-use insecticidal soap once per day as needed, thoroughly covering all leaves and stems. Hornworms are thick caterpillars that grow to about 4 inches long. These pests can eat all the leaves off tomato plants overnight. Remove hornworms by picking them off plants as soon as they are seen. For a severe infestation of hornworms, apply a solution of Bacillis thuringiensis to the leaves of tomato plants in the evening; mix about 1 tablespoon Bt per gallon of water, but always follow your brand's label instructions. Reapply each night as long as hornworms are present. Store Bt out of reach of children and pets. Banishing Blight Tomatoes are not particularly prone to disease, but yellow and brown leaves close to the ground may indicate blight. The only way to control blight is to remove damaged leaves as soon as they are visible. Burn leaves or put them in the garbage. Never compost diseased leaves. To prevent blight, select a blight-resistant variety and practice crop rotation by planting tomatoes in a different spot each year.

Tomato plants (Lycopersicon lycopersicum) technically produce fruits, but people use the fruits as vegetables in salads and other dishes too numerous to list. Unfortunately, squirrels eat tomato fruits, too, passing up unripe green ones to eat only those that are ripe red. Foiling hungry squirrels is never simple. Tomato plants usually are grown as annuals. [图片]Use Dogs and Cats The old-fashioned method of letting a dog roam the garden is one way of discouraging squirrels from eating tomato fruits. They don't like cats either. Cats prey on squirrels. Not all dogs are equal for this chore. Some dogs are squirrel specialists. For example, the American squirrel dog is bred to chase squirrels. A German pinscher is specifically bred to chase squirrels and other rodents. Build Physical Barriers Keep squirrels from eating your tomato fruits by covering your plants with plastic bird netting, chicken wire or hardware cloth; all of those barrier items are available at many garden supply centers. Whether or not this method is practical depends on the variety of tomato plants you grow. Indeterminate tomatoes, including heirloom varieties, yield fruits all summer, but those plants are climbers that need to be staked. They can grow 10 to 12 feet tall, although 6 to 8 feet is more usual, hardly a size that you can easily surround with a barrier. Determinate tomatoes, which usually bear fruits in late June, typically remain under 5 feet tall. So they are possible candidates for covering with bird netting. Dwarf tomatoes, which are hybrid determinate cultivars, grow as low as 3 feet high and spread 3 feet wide. They are small enough to cover with bird netting or even chicken wire or hardware cloth. Cage small determinate or dwarf tomato plants by encircling each of them with chicken wire and stringing bird netting over each one's top. Fasten the netting in place with clothespins. When you harvest your tomato fruits, simply remove the netting, and then put it back in place. [图片]Wrap individual ripening tomato fruits with bird netting. Use Smell, Bad and Good Squirrels can smell predators, including dogs and cats, and avoid predator-scented areas. Collect dog or cat hair in a vacuum cleaner, or get some from a pet store. Put the hair in a nylon stocking or porous bag, and place the stocking or bag at the foot of your tomato plants. A variation of this method is to spray urine from wolves or other squirrel predators on the ground at the base of your tomato plants. Some garden supply stores offer predator urine. Squirrels avoid the odor of blood meal, too. It is a dry powder extracted from slaughterhouse waste and sometimes is used as an organic fertilizer; it is available at plant nurseries and garden supply centers. Spread blood meal on the soil around your tomato plants, using fewer than 4 ounces of blood meal per 1 square yard. Blood meal contains high levels of ammonia and nitrogen; so do not apply more than that amount. Combine 5 ounces bottle of hot pepper sauce and 1 teaspoon of a liquid, mild detergent with 1 gallon of water, and spray the mixture on the bases of your tomato plants. Respray the plants with the mixture every few days for two weeks while the squirrels learn to avoid your tomatoes. Also respray after it rains. Establish a squirrel hangout with peanuts, corn, sunflower seeds and other food squirrels eat; you could even include some tomatoes in the mix. Give the squirrels water at the hangout, too. Place the hangout in an isolated spot well away from your tomatoes. If they get their fill at the hangout, they'll have no reason to raid your tomatoes. Use Water and Motion Install a motion-activated sprinkler that will douse the critters with water when they invade your garden. Another option is to install pinwheels, compact disks or aluminum pie tins in your garden. They will move and flash whenever the wind blows. These items work for a while, and then squirrels get used to them and go for the garden's tomatoes.

If you have a vegetable garden or are thinking of starting one, tomatoes (Lycopersicon esculentum) are likely on your list of plants to grow. If you're looking for a variety that has flavorful, all-purpose fruits, a tomato called "Better Boy" could be the perfect choice. An indeterminate plant that keeps growing all season long, this plant thrives in strong light and good garden soil, with just a little extra care ensuring a heavy yield. Tomatoes are grown as annuals in all parts of the United States. [图片]Planting Seedlings Sow "Better Boy" seeds indoors about six or eight weeks before you expect outdoor temperature to stay above 45 degrees Fahrenheit at night, using moist sterile potting soil or soil-less mix. Cover seeds with 1/8 inch of mix and, once seedlings appear, keep them in a sunny spot or under fluorescent grow lights. You can also buy seedlings at a garden center but, in either case, harden plants off for a week or two by gradually increasing their exposure to outdoor air and light. Space "Better Boy" seedlings 2 to 3 feet apart , with 4 feet between rows. Remove the bottom two leaves from each plant and plant in a deep hole, so that these leaf nodes are covered by soil. Planting deep encourages rooting from the stem, making a well-seated plant. Sun, Soil and Water "Better Boy" tomatoes thrive and fruit heavily when grown in a spot that gets full sun, with six hours of sun a minimum for good results. They also need fertile soil. When planting, add 2 or 3 inches of compost to the bottom of each hole, along with a handful of bonemeal. Tomatoes also need magnesium for a good start; add 1 teaspoon of Epsom salts to each hole to provide this mineral. Water the seedlings in well and then water evenly during the season, aiming for about 1 inch of water each week, including rain. To prevent fungal problems, water early on sunny days so plants dry quickly, and use a soaker hose or drip irrigation to help keep foliage dry. Feeding and Pruning It takes about 70 days to get the first ripe "Better Boy" tomatoes, but feeding the plants is important for a good harvest. Start fertilizing when the first fruits are about 1 inch in diameter, and then feed again when harvest begins. Use a low-nitrogen formula such as 5-10-5, side-dressing each plant with about 1/2 cup of the granular fertilizer, but turn the fertilizer into the soil gently to avoid disturbing roots. [图片]"Better Boy" is an indeterminate variety that grows all season long, so it benefits from pruning to maximize fruiting and keep its size under control. As the plant grows, allow only one or two main stems to grow and remove suckers -- shoots appearing where each leaf originates -- to funnel the plant's energy into fruiting, using shears that you wipe with rubbing alcohol between cuts to prevent spread of disease. Also, help the plant produce the last ripe fruits by cutting back its fruitless top near the end of summer. Support and Possible Problems "Better Boy" is a heavy producer, with individual fruits weighing up to 1 pound each, so they benefit from support while growing. Either drive a sturdy stake into the ground, using soft ties to attach the stem to the stake at intervals, or use a commercial tomato cage for support, tying the plant to its wire as needed. These plants are susceptible to fungal disorders and fruit cracking, but ensuring constant, even moisture and giving plants lots of space in well-drained soil helps avoid these problems. They can attract pests such as large green hornworms and striped potato beetles, which can be hand-picked, and aphids, which are best controlled by washing plants with a strong water stream.
