Growing potatoes

Digging is a job that few gardeners, especially those new to gardening, really enjoy. Almost everyone try to find the easy way out to avoid all that back breaking effort, and for most jobs.
In this cases, a rotary powered cultivator is the answer. Using rotary cultivator it won’t do the double digging where you will be loosening the soil to a depth of 18in (45cm) and it can be a great boon.

But before looking at what a rotary cultivator can do to make life easier in the garden, perhaps it’s worth talking about what could be a drawback — the price. You’ll have to pay a pretty sum for a petrol powered machine that can cultivate deeply.
Moreover if your soil is heavy you’ll need to pay a great deal more for a machine which is sufficiently powerful to go down deep. If you just have a small garden, forget it, it just isn’t worth the money.

There are two alternatives. You can hire one from a hire shop and this will give you the chance to get a strong powerful machine on the few days when you need it. The advantage is that there is no need to worry about maintenance.
Here is only the problem of getting it home. You may need an estate car.
The other alternative is to get together with neighbors or get your gardening club or allotment society to buy one you can all share.

This again will help you get a good machine at a reasonable price.

Now, what it can do for you. This depends on the cultivator you buy.
The best cultivators will cultivate to a depth of about l0 in (25cm) by breaking up the soil into small granules and mixing them up. You can distribute your compost on the surface and it will be mixed with the soil more evenly than you could do it with a fork. Set to cultivate lightly it acts more as a hoe and is ideal for dealing with low weed growth amongstvegetables.

Attachments are available to help you earth up potatoes or to plough, hut only on the larger rotary cultivators are these likely to be successful.

Oxygen requirements of potatoes tubers are fairly high at 0°C, and least at 5°C.
They increase up to 16°C and are high at 25°C and above.

Therefore, oxygen deficiency of cells in the potato tuber center can occur at temperatures either too low or too high.
Injury develops in both the field and storage, particularly if air movement is restricted around tubers. Rapidly growing potatoes tubers have high oxygen requirements.

Black heart—blackening of the tuber center —follows acute oxygen deficiency associated with either low temperature in confined storage or high field soil temperatures.

Affected potatoes tubers rot later. Internal heat necrosis, a field problem, is a less acute high-temperature injury in which groups of cells become rust-colored, particularly in the centers of large potatoes tubers.

Internal heat necrosis is often severe in sandy or mucky soils exposed to solar heat following early vine death and delayed harvest.

Rot is usually not a severe problem. Potatoes tubers with oxygen deficiency symptoms should not be used as seed.

Avoid high field soil temperatures by harvesting promptly after vines are killed. Maintain cold storage at 4°C or slightly higher. Improve aeration in potatoes storage.

Potato Mop-Top V irus (PMTV) occurs in areas with cool, damp conditions that favour spread of its fungus vector, Spongospora subterranea.

Symptoms of potatoes disease caused by Potato Mop-Top V irus Primary symptoms develop on and in tubers of some potatoes cultivars when they are infected directly from the soil.

Usually, only some stems on a plant are infected so that an affected plant also has normal-looking stems.

The virus survives in soil and spreads to new areas mainly through resting spores of the fungus vector, carried in soil or on seed tubers.

Management treatment of infected soil with calomel, sulfur, or zinc oxide can inhibit infection of a healthy potatoes crop. Roguing is useful with potatoes cultivars that produce strong symptoms.

(Alternaria solani) Early blight or Alternaria blight is worldwide in distribution and is one of the most important potato foliage diseases in areas with favourable weather conditions.

Symptoms of Early Blight Brown, angular, necrotic spots marked internally by a series of concentric rings form on leaves and to a lesser extent on stems.

Leaf lesions are seldom circular because they are restricted by the larger leaf veins. Lesions usually develop around flowering time and become increasingly numerous as plants mature. Lesions first form on lower leaves.

They may join and cause general yellowing, leaf drop, or early death. Tuber rot is dark colour, dry, and leathery.

Susceptible varieties of potatoes (usually early maturing) may show severe defoliation. Later maturing varieties may appear resistant.

Potato plants under stresses that hasten maturity (such as adverse environment, warm, humid weather, other diseases, or nutritional deficiency) become susceptible and die prematurely. Management Provide conditions for vigorous growth throughout the season, especially irrigation and fertilizer side dressing.

Organic fungicides sprayed on the foliage reduce the spread of early blight. Resistance is available among late-maturing varieties.

(Streptomyces scabies)

Scab is a common tuber defect in most potato-growing regions, although usually not where soils are very acid.

The causal organism has been introduced into most potato soils. It affects only quality, not yield. Symptoms of Common scab Several types of lesions develop. They may be superficial or reticular, deep or pitted, or protuberant.

They vary in size and shape, but are usually circular and not more than 10 mm in diameter. They may coalesce so that most of the tuber surface becomes affected. Fibrous roots may also be damaged. Management Maintain high soil water levels compatible with good potato growth during tuber set and enlargement.

Avoid planting scabby potatoes seed tubers. Avoid repeated crops of potato or other scab-susceptible plants such as red beet, sugarbeet, radish, rutabaga, turnip, carrot, and parsnip (in these, the disease seldom has economic importance).

Scab-resistant varieties are useful. Maintain soil pH levels at 5 to 5.2 with acid-forming fertilizers or sulfur. Avoid heavy lime applications and preferably use dolomitic lime where needed.

“Acid scab” may be controlled with chemical seed treatments (mancozeb dust, 8%) or soil fumigation.

Soil moisture can limit potato growth.

The amount of water required is influenced by soil type, temperatures, wind, and cultural practices. A general rule of thumb is to provide 1 to 1.5 inch of water weekly until just before harvest. Several critical periods need special attention.

When the vines are 6 to 8 inches tall, tubers start to develop and watering during periods of dry weather will help ensure adequate numbers of tubers. In dry years, the size and quality of potatoes can be improved by a thorough watering 1 to 2 weeks before harvest.

Regular watering throughout the season is suggested, however, to help prevent problems such as knobbiness, second growths, cracking of potato tubers, and hollow cavities in the centers of tubers.

Overwatering, on the other hand, can cause black or hollow centers in potatoes.

Drip irrigation can be used successfully with potatoes and may even lessen disease pressure by reducing the amount of moisture on plant leaves.

For a top yield you should keep your potato vines well watered during the growing season, and special during the time that the potatoes are blooming, because during blooming the plant start with the developing of the new tubers.

The best time is to water of potatoes in the morning, so that the leaves can dry up, this will prevent diseases.

As soon as the leaves are turning yellow and start to die you should discontinue watering to allow he skin of the tubers to harden off before harvesting.

Traditionally potatoes are grown in rows. Distance between planted potatoes seed is 15 in., with the rows spaced 2 1/2 to 3 ft. apart.

If space in your garden is limited or if you would only like to grow a small crop of potatoes, you may prefer to plant one or two potato mounds.

Each 3-4 foot diameter mound can support 6 to 8 potato plants. With either method, the first step is to cultivate and turn the soil one last time before planting, removing any weeds, rocks or debris.

This will loosen the soil and allow the plants to become established more quickly.

Your potato plants will benefit from the addition of compost.

However, too much organic material can increase the chances of potato scab. Potato scab is a bacterial infection which doesn’t affect the usability of your potatoes, but it makes them look pretty ugly.

To lessen the likelihood of this, mix the organic matter into the soil below the potato seed, where it will feed the roots, but not contact the newly forming potatoes.

How to plant potatoes in row

Dig a shallow trench about 4 inches wide and 6-8 inches deep.

The spacing at which you place potatoes will determine the harvested potato size.

For most household uses, you will want to plant potato 15 inches apart in this trench.

The potato tuber cut on pieces plants to grow a new potato plant. When the piece of potato tuber is planted it is called a “seed” potato.

Only certified seed potatoes should be planted in the home garden. Certification insures that the seed tubers are free of disease.

Certified seed can be obtained from a number of reputable garden supply stores. Do not purchase potatoes from the grocery store to plant in the home garden.

These may carry harmful potato diseases that will hurt the growth of your crop.

Tubers at the grocery store may also be treated with sprout inhibitors that may also hurt the growth of the plant in the garden.

Potato tubers have buds known as eyes on the skin surface from which new plants grow (or sprout).

Tubers are ready to cut into seed pieces when one or more of the eyes begin to sprout. However, they can be cut before the eyes sprout.

Cutting the potato into seed will cause more eyes on the seed to sprout. After selecting seed potatoes, cut them into seed pieces weighing approximately 1.5 to 2 ounces.

Smaller-sized seed pieces usually result in weaker plants and reduced “recovering” capabilities when a late frost injures emerging potato vines.

If you can buy small seed, no cutting is necessary—just plants each seed.

Each cut potato seed piece should be block-shaped and should contain at least one eye or short sprout.

In cutting seed, it is preferable to make the first cut lengthwise to divide the cluster of eyes that are evident at one end of the potato.

Each pound of seed contains an average of eight to ten potato seed pieces. In estimating how much seed to purchase, remember that it takes about 9 to 10 pounds of seed potatoes to plant 100 feet of row.

An important practice to discourage rotting of potato seed pieces is to “heal” the freshly cut pieces by storing them at room temperature (60–70˚F) with fairly high humidity for 5 to 7 days before planting.

This allows the freshly cut surfaces to develop a protective coating that will help prevent potato seed decay.

Growing potatoes in bags is very simplest growing potatoes way you can use if you have a lack of place in garden.

The bags with planting potatoes you can put in any sunny places. You no need a garden, no digging.

Bag holds 36 quarts of soil and has Drainage holes in bottom. Unlike regular pots and plantes, these bags take up virtually no storage space when the season is over.

Choose you favorite variety seed of potatoes. Cut off on 3 or 4 parts and be sure that each has 1-3 eyes. Put them in bag with eyes up.

You should plant between 3 to 5 seed potatoes per bag. Place the bags in any sunny place. You can add compost or fertilizer if it is necessary. Water you potatoes properly.

When your potatoes are ready, empty out the bag and enjoy the real taste of home grown potatoes. For best results use 3 bags and plant every 4 to 6 weeks to spread your harvest over a longer period. Webbing handles make it easy to move around.

Bags for growing potatoes are made from woven polyethylene with wipe clean surfaces. Flap at bottom of bag allows you to check your potatoes.

It is very fun and simple way to grow your own potatoes in buckets. You can do it with your children.

All what you need for growing good yield of potatoes are buckets about 50 cm (20 inches), compost or soil and seed potatoes.

Certainly, you need to drill holes in your bucket for drainage. Also you should drill the holes about 2-3 inches from the bottom of the container on the side of the container at least six inches apart.

Then you need to prepare potatoes seed. Place the potatoes which you want to plant in a warm site with plenty of light so that their shoots start growing. It should be done about ten days before planting.

Cut the potatoes on pieces with at least 3 eyes on each. Do not cut them if your potatoes are less than 2 inches long.

Put the seed potatoes with the eyes facing up. Then fill the bucket near to the top with compost or soil.

When you grow potatoes in a bucket you can use garden soil, potting soil, pure compost, or a combination of peat moss, wood chips, compost, and perlite. You’ll want to be sure your potting medium, whatever you choose, will allow for enough aeration so that the soil does not become compacted. Put about 4 to 6 inches of potting medium into your bucket.

Place the bucket in a spot that has reasonable light on bricks for drainage. The ideal temperature to grow potato in buckets is 10-15° C (or 50-60° F).

Don’t forget to turn the bucket regularly so the plant grows straight, and keep the soil moist.

There are many premade containers and buckets you can buy that are specifically meant for this purpose. Your own using wood, plastic buckets with the bottom cut out are also good when you decide to grow potatoes in buckets.
