Vertical farming Select the correct answer using the code given below: (a) 1, 2 and 3 only (b) 3 only (c) 4 only (d) 1, 2, 3 and 4 4. With reference to solar water pumps, consider the following statements:
  1. Solar power can be used for running surface pumps and not for submersible Pumps.
  2. Solar power can be used for running centrifugal pumps and not the ones with piston.
Which of the statements given above is/are correct? (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 5. Other than poaching, what are the possible reasons for the decline in the population of Ganges River Dolphins?
  1. Construction of dams and barrages on rivers
  2. Increase in the population of crocodiles in rivers
  3. Getting trapped in fishing nets accidentally
  4. Use of synthetic fertilizers and other agricultural chemicals in crop- fields in the vicinity of rivers
Select the correct answer using the code given below. (a) 1 and 2 only (b) 2 and 3 only (c) 1, 3 and 4 only (d) 1, 2, 3 and 4 only   ANSWERS 1. (b) - The assets of the commercial bank in India are Cash in hand, Investments, Loans, Advances, Bills discounted and purchased, while the liabilities are Capital and Reserves, Deposits, Borrowings, and other liabilities. 2. (c) The ‘Sarkaria Commission’ recommended that the Governor should be an eminent person from outside the state and should be a detached figure without intense political links. Governor should not have taken part in politics in recent past and should not be a member of the ruling party. The Commission was set up in June 1983 to examine the relationship between state and central governments. 3. (d) Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value added crops with complementary marketing opportunities. Introducing a greater range of varieties in a particular agro - ecosystem leads to diversification of agricultural production which can also increase natural biodiversity, strengthening the ability of the agro-ecosystem to respond to these stresses. So (1) is correct. The discourse on Legume intensification is currently framed as ‘Sustainable Intensification’ (SI), and commonly encompasses three dimensions: (i) increased productivity; (ii) maintenance of ecosystem services; and (iii) increased resilience to shocks. So (2) is correct. When the water pressure in the tensiometer is determined to be in equilibrium with the water pressure in the soil, the tensiometer gauge reading represents the matric potential of the soil. Such tensiometers are used in irrigation scheduling to help farmers and other irrigation managers to determine when to water. Its also considered as eco-friendly agriculture as it help control the excessive use of water distorting the quality of the soil. So (3) is correct. Vertical farming is the practice of growing crops in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. So (4) is correct. 4. (d) Solar water pumps are specially designed to utilize DC electric power from photovoltaic modules. The pumps must work during low light conditions, when power is reduced, without stalling or overheating. Low volume pumps use positive displacement (volumetric) mechanisms which seal water in cavities and force it upward. Lift capacity is maintained even while pumping slowly. These mechanisms include diaphragm, vane and piston pumps. These differ from a conventional centrifugal pump that needs to spin fast to work efficiently. Centrifugal pumps are used where higher volumes are required. A surface pump is one that is mounted at ground level. Surface pumps work well when they draw water through suction less than 10 or 20 feet. A submersible pump is one that is lowered into the water. Most deep wells use submersible pumps. And both are compatible with the photovoltaic array (For Solar power). 5. (c)
