Hi bloggers.hope you are all doing good and safe.
Protected cultivation is the modification of the natural environment to achieve optimum plant growth.
PRESENT SCENARIO OF PROTECTED CULTIVATION:
In general, protected structure are used to overcome low temperature in temperate region or high temperature in the countries having tropical climate.the need of protected structure directly depends upon the climate of the region, growing season and kind of crop to be grown.
HIGH TECH OR CLIMATE CONTROLLED GREENHOUSE:
this type of green house is constructed to achieve higher degree of climate control to enhance the cultivation period of crops.evaporative cooling and heaters are used to maintain required temperature inside green house spaces as and when needed.the climate is usually accomplished through automatic systems.
Such type of green house is used for growing high value blemish free crops tomato,cherry tomatoes,sweet pepper, cucumber for long period.these green house are mainly being used in several European countries.,Morocco,Israel,usa and Japan.
These greenhouse are mostly used for long duration cultivation of tomato and sweet pepper over a long period of time.in most of the countries,the green house are made of plastic except the glass greenhouse in netherlands.glasshouse and rigid plastic houses are longer life structure and are therefore mostly located in cold regions,where these structures and are therefore mostly located in cold regions,where these structures can be used for the crop production throughout the year.asian continent has maximum area under green house and china leads amongst countries follow by Italy,Spain,japan.
Prospect and strategies:
Protected cultivation undoubtedly offers several advantages to grow vegetables of high quality even under unfavorable climatic conditions.this production system however require high input costs and good management.whether it is economic viable depends on the cost incurred on the structure and the remuneration earned for the produce.above all,to make its succeed venture growers need to make proper planning and vigil.
Advantages:
Production of quality produce.
Provides good economic return
Provide opportunities for export.
Hope you guys came to know about minimum about protected cultivation.it includes lot of method and requires lot of strategy.future world depends on the protected structure cultivation due to the problem faced by the climate change and global warming.in a decade india will be the topmost country in protected cultivation progress.
Have a good day bloggers ❣️
