What is Organic Farming?
Organic farming is a technique used in farming without the use of any chemicals or synthetics. Its aim is to produce crops which have the highest nutritional values with least impact on nature. Crop rotation, green manure, use of natural fertilizers and biological pest control form the crux of organic farming. It is a proactive ecology management strategy. This strategy enhances the fertility of the soil, prevents soil erosion and at the same time protects the humans and animal kingdom from the side-effects of chemicals and synthetics. Many of the farm products, like, vegetables, fruit, herbs, meat, milk, eggs, etc. are produced organically by some farmers.

“Organic” as defined by law, implies quality assurance. The words “natural” and “eco-friendly” mean that organic farming techniques might have been used, but it does not necessarily mean completely following organic techniques.

Pros and Cons of Organic Farming
Like everything else, organic farming also has its pros and cons…
The most important of the advantages of organic farming is that it maintains the life of the soil, not only for the current generation, but also for the future generations. Water pollution is reduced with organic farming. Most of the time after it rains, the water from the fields, which contains chemicals, gets drained into the rivers. This pollutes the water bodies. In organic farming, since no chemicals or synthetics are used, water pollution reduces as well.

Organic farming helps in building richer soil. Rich soil is obtained by intelligently rotating crops. The rich soil helps in plant growth. The rate of soil erosion is reduced drastically. A French study has revealed that the nutritional quality and micro-nutrients are present in higher quantities in organically produced crops. The micro-nutrients promote good health. Organically grown food tastes better too. The overall cost of cultivating the crops reduces as the farmers use green manure or worm farming to replenish the lost nutrients of the soil. The other option that the farmers use, is to grow legumes in rotation with other crops. The life of organically grown plants is longer than the plants cultivated by traditional methods. Organically grown crops are more drought tolerant. The chemical fertilizers cause the plant to ripen fast. When the crop does not get water it withers and dies, which is not the case with organic crops.

Along with the pros, there are certain cons too. The first disadvantage is low productivity. With the highly developed chemicals and machinery, the farmer is able to multiply his harvest manifold times. The organic farmers use the cultivation method as opposed to drilling method used by the traditional farmers. The cultivated soil is prone to wind and water erosion. The traditional farmers opine that direct drilling does not cause any disharmony in the soil structure. The next argument is that the organically produced food is expensive. The cost is very often 50-100 percent more than the traditional food. The other valid argument is that organic food is not always available. There is a reason behind that. The organic farmers grow crops in accordance to the season. Neither do they artificially grow any crop nor do they extend the life of the plant or use chemicals, synthetics or pesticides. Therefore, oranges will be found only in winter and mangoes only in summer. Looking at it from the health benefits point of view, there is no doubt that you will benefit if you eat a particular food item, when it is actually in season.

After weighing the pros and cons of organic farming, it is noticed that the pros outweigh the cons. It is therefore best to consume organically grown food, although it is expensive.

What Constitute a Vegetable, Herb or Fruit?

We have all come across these terms. And frankly speaking, they can be confusing. For example, the tomato can sometimes be considered a bit of both fruit and vegetable and some books consider a banana herb and not a fruit. But is there a clear cut definition?

Botanically speaking, anything that bears a seed or is a seed is considered a fruit. There are different kinds of fruit, i.e. nuts are a kind of fruit.  Vegetables are any part of the plant that doesn’t have to do with making new plants. Lettuce is a leaf, carrot is a root, and celery is a stem.  I think I heard a story of how the legal definition of a fruit vs. veggie was established as a way of avoiding taxes or tariffs or something.

Technically, a tomato is a berry.  Just for further enjoyment, an apple is a fluid-filled hypanthium.  🙂 The particular item you are discussing will determine the specific best term to describe it. Generally you can safely call the product of fertilization a “fruit”.  (In the supermarket we routinely call the structure bearing fruits “fruit”). Generally fruits will germinate into plants which will again flower, offering another opportunity for fertilization. (Note that bananas we find in the store bear tiny almost-remnants of seeds which will not germinate…in the wild, banana “fruits” have seeds (fruits, being the products of fertilization) which are much larger which will germinate).  If one discusses a part of a plant which is not the direct product of fertilization or the structure bearing it, then one could safely call the item an herb.  For example, basil leaves are vegetative structures not specifically the result of fertilization and are most easily described as herbs. We do not have an adequate definition for ‘vegetable’, but our feeling for its routine meaning is any part of a plant consumed whether a stem (celery), a leaf (lettuce), a root or tuber (radish, or potato, respectively), and in some cases the fruit of fertilization or structures bearing them (cucumbers, yes-tomatoes).  Added to this are items such as mushrooms (basidiocarps of fungi) and you get the idea….the term vegetable has come to mean almost anything which is not animal or mineral which we find in the ‘produce’ section of the supermarket.  Thus, the term vegetable has somewhat lost a botanical usefulness in that there are more specific terms to use depending on the particular structure being discussed. Note that there are specific botanical definitions for berries which can be found in any good plant classification text; you can see this is essential, for example, in distinguishing between raspberries, blueberries, and tomatoes (also berries). We hope this shed some light on the challenge of plant classification and gives some insight as to why scientific names were established to pin down a particular organism to prevent confusion with many common names or possibly similar terms for different organisms.

The transplanting process can be a shock to rapidly growing seedlings especially when set out into the cold windy garden in the spring. This is especially true for transplants started in the greenhouse, cold frame, hotbed or home. These young seedlings can be made somewhat resistant to heat, cold temperatures, drying and whipping winds, certain types of insect injury, injury from blowing sand and soil particles and low soil moisture by a process termed “hardening.”
The term “hardening” refers to any treatment that results in a firming or hardening of plant tissue. Such a treatment reduces the growth rate, thickens the cuticle and waxy layers, reduces the percentage of freezable water in the plant and often results in a pink color in stems, leaf veins and petioles. Such plants often have smaller and darker green leaves than non hardened plants. Hardening results in an increased level of carbohydrates in the plant permitting a more rapid root development than occurs in non hardened plants.
Cool-season flower and vegetable plants can develop hardiness allowing them to withstand subfreezing temperatures. Unhardened cabbage seedlings have been reported to be damaged by temperatures of -2 degrees C (28 degrees F) while hardened cabbage will tolerate temperatures as low as -6 degrees C (22 degrees F).
Warm-season types of plants even when hardened, will not withstand temperatures much below freezing. If transplanted to the garden or field prior to the average last killing spring frost, such plants should be provided protection by hot caps or other such devices.
Any of the following can be used to harden transplants. A combination of all these techniques at one time is more effective.
1. Gradually reduce water – water lightly at less frequent intervals but do not allow the plants to wilt severely.
2. Expose plants to lower temperature than is reported as optimal for their growth. If biennials are exposed to cold for an extended period, they may bolt in lieu of developing properly. Note: Placing the plants outside during the day to encourage hardening and then bringing the plants back into the warm house during the night often reverses the hardening process. Plants could be placed in a cold frame or other area that does not freeze during the night hours without lose of the hardening process.
3. Do not fertilize, particularly with nitrogen immediately before or during the hardening process. A starter solution or liquid fertilizer could however be applied to the hardened transplants one or two days prior to transplanting into the garden or at the time of transplanting.
4. Gradually expose the plants to more sunlight. This results in the development of a thicker cuticle layer thereby reducing water loss.
Hardening is not necessary for all transplants. We recommend that with the exception of tomatoes, plants that are susceptible to frost should not be hardened. Overly hardened plants while withstanding unfavorable outside conditions are slow to get started and may never overcome the stress placed on the plant during the hardening process. We also recommend that plants be hardened for no longer than seven to ten days before planting to the garden site.
