Modern day lifestyle has taken its toll on agriculture. People are forced to cultivate in large numbers to suffice the ever-growing population. Also tremendous improvements in the field of agriculture have raised the overall productivity by large number. Also one can have greater yield from a particular land. Improved seeds and irrigation methods have brought greater interest among the cultivators. Also irrigation methods like drip agriculture, has been welcomed by people all over the world. Though its capital cost is quite high. The running cost involved is manageable and also can yield huge benefits for the cultivators. Researchers have also developed newer ways of cultivation. These cultivation methods have produced amazing results in past two decades. Greenhouse cultivation is one such unique discovery that had revolutionized the thinking of common man. There are some cultivation methods that are suitable only for particular location but greenhouse cultivation can be adopted in any region of earth provided it receives enough sunlight.
Greenhouse cultivation
Greenhouse cultivation can be regarded as cultivation of variety of crops within closed room entitled by glass walls. Also roof of greenhouse would offer better gateway to sunlight. Basic ideology of greenhouse is that to trap the heat generated through sunrays and making it available for the plants to survive on it. Also there are quite unique advantages provided by greenhouses for the plants within glass walls. The heat retaining capacity of greenhouse has indirectly activated the plants. It had stimulated metabolic mechanisms to speed up. This greenhouse has also protected surface contaminants that tend to travel through air. Clean air can be supplied to the plants that are cultivated. Also greenhouse plants can enjoy the cushion of having protected environment. The greenhouse shields them from all pollutants that are air-borne. The site selection and construction play a major role in the cultivation of crop. The proper aesthetic design can permit clean airflow throughout site. Variety of plants can be grown in greenhouses. Vegetables, fruits, ornamental plants and medicinal plants can be grown in greenhouse.
Vegetable cultivation in greenhouse
Schwen Greenhouse in Winter
Vegetables can be grouped based on their season al growth and harvest periods. There are some plants that throng during the summer season. Some plants would love cold conditions. Summer vegetables like tomato need sufficient sunlight throughout their cultivation period. Proper ripening of fruits can be instituted by optimum sunlight. Presence of excessive moisture can damage the plants. Also the fruits can be damaged by moisture. There are vegetables like radish, broccoli that find winter season as comfortable for them to grow. Their harvest can be scheduled during winter season. So these vegetables can be termed as winter vegetables. Cultivation of vegetables of different kind can be brought under common roof through greenhouse cultivation. Green house cultivation of vegetables needs careful monitoring. Effective care of plants can yield huge turn over at end of cultivation.
Protection from cold
Winter vegetables are morphologically structured to resist low temperatures. But vegetables that grow in summer come under serious damage when the temperature drops below certain level. Winter season takes huge toll on vegetables like tomato. So greenhouse cultivation has employed thermometers at various locations to monitor the temperature change that takes place. One can identify any lowering of temperature through thermometer indication. If any situation occurs what should a cultivator do? This question arises in mind. The answer would be to have heaters to regulate the temperature. Electric heaters are available to take care of any temperature change. One can also use thermal regulators to produce desired temperature as suitable for the crops. This can eliminate excessive damage to surface of leaves through cold conditions prevailing inside the greenhouse. Also some cooling devices are to be installed if the heaters over do their job and produce totally non-conducive environment for plants.
Things to remember for farmers
There are several things that a cultivator should keep in mind before adopting artificial heating to the greenhouse. Excessive heating can be catastrophic for plants. Also one needs to have proper precautionary measures if the temperature reaches beyond the permissible levels. Extreme situations are to be worked out before hand to avoid costly mishaps. The heaters used in greenhouse should be checked periodically for correctness. Also monitoring the behavior of plant’s vegetative part can regulate effective cultivation.
The climatic conditions of all the areas throughout the world are drastically changing. The reasons for this sudden change weather are many. Some of them are:
- Depletion of the ozone layer.
- Increased greenhouse gases.
- Over pollution.
- Intake of high energy from outer space.

Due to these reasons there has been a situation of irreversible climatic change that has occurred to our mother earth. The past procedures what we followed for many things are not possible on today’s date. So a new approach to the existing procedure must be followed in order to survive in this world. This case is also applicable to agriculture.
We all know that for every man living they have to depend upon food, which is got only through cultivation. The day old cultivation procedure followed by all the men are outdated and has many problems associated with it. They are:
- Too high utilization of water.
- The place required for cultivation has to be very large, which is not usually got.
- Proper water supply must be there, which is also not possible due to drying up of rivers.
Due to these reason the conventional method has failed to make up to the expectation of the humans. The remedy to the current crisis is to go in for greenhouse cultivation.

Greenhouse cultivation is the process of growing the plants in a closed atmosphere mostly a glass house. This method made its existence due to its capability to grow plants in cold environment. It traps the incoming sunlight and makes it warm for the plants to grow. But nowadays the greenhouse is used more extensively due to the following reason.
- Due to the availability of natural heat within the greenhouse.
- The advantage of closed environment is associated with the greenhouse.
- The timely watering should be done in this process.
- The unmanned cultivation is possible with the greenhouse.
- The growing up of plants one over the other can also be done.
These advantages go hand in hand with the development of the greenhouse. The temperature inside the greenhouse can be increased extensively by the use of small greenhouse heaters. By using them a temperature of 70 degree can be maintained when the outside temperature is 0 degrees. They are available with various specifications. One of the configuring methods is based upon the size and heating temperature. The price associated with the heater is too little and the method they work is simple so the works can be easily monitored.
This handy portable heater is ideal for controlling the temperature in conservatories and greenhouses. It has 2 heat settings as well as a cool air option. It also features a thermostatically controlled frost guard.
The cultivation field has found turmoil due to the fewer amounts of rainfall and abnormal weather condition prevailing throughout the world. The rate of death due to no intake of food has increased rapidly. The reasons for these things are:
- The climate is changing rapidly due to many factors like ozone depletion and greenhouse effect.
- The other thing that retards the growth is the over pollution. This has changed the morphology of many plant specimens.
- The rainfall level did not to the expected level. This has also resulted in the drying up of many plants.
- The other most important reason is the over population which has left the growing demand of food in geometric progression while the demand satisfactory rate is in arithmetic progression.
These things have left us with a forced improvement in the field of cultivation. The revolutionary method that got its applause from all the people around the globe is the greenhouse cultivation method.
What is this method?
This method is a new comer to the field of cultivation. The idea about this is not known to many of the people. This is nothing but growing the plant in a closed atmosphere. The origin of this method dates back to 17 the century. This method was developed only to make the plants grow in extreme cold weather. The working principle of this is very simple as this works by making the trapping of sunlight and there by increasing the temperature inside the greenhouse and makes it suited for the plants. But the greenhouse has made considerable amount of improvement in recent years. The process that they have additionally added is due to the advancement in the field of science. The various add-ons to the greenhouse are growing plants one over the other. Automatic watering of the plants is also possible with this process. The plants can be made pest free and protective growing makes them mare yielded than their competitors on the normal ground. The plants that are grown on the greenhouse are different as they use different greenhouse seeds. The greenhouse seeds are made genetically adaptable to the closed environment and yield higher than their counterparts. For this reason alone people prefer the greenhouses rather than the normal conventional way. The seeds are made only after special treatment and prolonged research. The reason for this is that they have to serve the purpose of making. The seeds are far more better and pest resistive than the normal seeds. Going in for these is intelligent.
