  1. Crop rotation

  2. Inter-cropping

  3. Mixed cropping

  4. Intra-cropping

Show answer
Correct Option: B
Explanation:
Inter-cropping is growing two or more crops simultaneously on the same field in a definite pattern. A few rows of one crop alternate with a few rows of a second crop. The crops are selected such that their nutrient requirements are different. This ensures maximum utilization of the nutrients supplied, and also prevents pests and diseases from spreading to all the plants belonging to one crop in a field. Thus, both crops give better returns.
So, the correct answer is 'Inter-cropping'.

  1. It makes better use of natural resources, sunlight, land and water

  2. Soil erosion is effectively arrested

  3. The produce of each crop can be marketed and consumed separately

  1. Crop rotation

  2. Mixed cropping

  3. Terrace farming

  4. All of the above

Show answer
Correct Option: B
Explanation:

Mixed cropping is a system of planting two crops at a time on the same land. It is also known as polyculture i.e two types of crops are sown and irrigated at a time. The benefits of mixed cropping are that the plant will get nutrients from the soils.

So, the correct option is ' Mixed cropping'.

Mixed farming referred only to ________________.

  1. Growing of crop together by mixing the seeds

  2. Growing of cash crops and food grains together

  3. Crop production combined with dairy farming at farm

  4. Growing of fruits and vegetable mixed

Show answer
Correct Option: C
Explanation:

Explanation: Mixed farming is an agrarian system that mixes arable farming with the raising of livestock at the same time. When on a farm along-with crop production, some other agriculture based practice like poultry, dairy farming or bee keeping etc. is adopted, then this system of farming is known as mixed farming.

  1. Crop rotation

  2. Inter cropping

  3. Mixed cropping

  4. None of the above

Show answer
Correct Option: C
Explanation:

When the same land is used for the cultivation of more than one crop is known as mixed cropping. The same field is divided into smaller regions. The seeds of different crops are sown and cultivation of different crops is carried out in the same piece of land. 

Thus, the correct answer is option C. 

Which of the following biofertilizer bacteria is a phosphorus solubilizer?

  1. Azotobacter

  2. Azospyrillum

  3. Basillus   & Pseudomonas

  4. Cyanobacteria

Show answer
Correct Option: C
Explanation:

A.Azotobacter is a genus of usually motile, oval or spherical bacteria . It has several metabolic capabilities, including atmospheric nitrogen fixation by conversion to ammonia.
B.Azospirillum bacteria can promote plant growth. 
C.The bacteria Basillus  & Pseudomonas convert non labile Phosphorous  through either inorganic Phosphorous solubilizing or organic Phosphorous mineralization processes.
D.Cyanobacteria, also known as Cyanophyta, are a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen.
So the correct option is ' Bacillus  & Pseudomonas ' .
