India has three distinct crop seasons in the northern and interior parts of the country, namely Kharif, Rabi, and Zaid.

Important Points

Lets' look at the cropping season of India:

• The Kharif season (June-September) largely coincides with Southwest Monsoon under which the cultivation of tropical crops are possible.
  • Major Crops- Rice, Cotton, Jute, Jowar, Bajra, and Tur.
• The Rabi season (October-March) has low-temperature conditions which help in the cultivation of temperate and subtropical crops.
  • Major Crops- Wheat, Gram, and Mustard.
• The Zaid season (April-June) is a short duration summer cropping season beginning after harvesting Rabi crops.
  • Major Crops- Watermelons, Cucumbers, Vegetables, and Fodder Crops.

From the above, we can conclude that Wheat is not a Kharif crop as it is grown in the Rabi season.

​The correct answer is Truck farming.

Key Points

• The farmers specialize in vegetables only, this type of farming is known as Truck farming.
• In the regions where farmers specialize in vegetables only, the farming is known as Truck farming, and the distance of truck farms from the market is governed by the distance that a truck can cover overnight, hence the name truck farming.
• Vegetable farms are in some regions known as truck farms: "truck" is a noun for which its more common meaning overshadows its historically separate use as a term for "vegetables are grown for the market".
• The production of crops of some vegetables on an extensive scale in regions especially suited to their culture primarily for shipment to distant markets known as Truck farming.
• The major truck-farming areas are in California, Texas, Florida, along the Atlantic Coastal Plain, and in the Great Lakes area.
• Centres for specific crops vary with the season. Among the most important truck crops are tomatoes, lettuce, melons, beets, broccoli, celery, radishes, onions, cabbage, and strawberries.

Concept:

Software maintenance:

Any changes done in the software during its execution such as error correction, optimization etc. is software maintenance. Its objective is to preserve the value of software over time.

Explanation:

Types of software maintenance are:

Perfective maintenance: when there are new requirements from user side, then at that time changes made in the software is known as perfective maintenance. It makes the software more enhanced, clean structured, better than previous.

Adaptive maintenance: Changes done in the software environment that includes any work initiated as consequence of moving the software to different hardware or software is known as adaptive maintenance.

Preventive maintenance: It prevent software from future problems.
