Q9032. Consider the following soil textural classes found in Rajasthan:
I. Clayey soil
II. Sandy soil
III. Silty soil
IV. Loamy soil
Arrange the above classes in the increasing order of their inherent water retention capacity:
I. Clayey soil
II. Sandy soil
III. Silty soil
IV. Loamy soil
Arrange the above classes in the increasing order of their inherent water retention capacity:
Explanation
The water retention capacity of soil is primarily determined by its texture and pore space. Sandy soils have the lowest retention due to large pores. Loamy soils have intermediate retention, followed by silty soils. Clayey soils, characterized by very fine particles and small pores, possess the highest inherent capacity to hold water, making them the most moisture-retentive among all classes.
Q9033. Read the following statements regarding the Indira Gandhi Matritva Poshan Yojana:
I. It addresses maternal and child undernutrition.
II. It provides cash benefits directly linked to specific maternal health behaviours.
III. It aims to finance the higher education of the mother.
Which of the above statement(s) is/are correct?
I. It addresses maternal and child undernutrition.
II. It provides cash benefits directly linked to specific maternal health behaviours.
III. It aims to finance the higher education of the mother.
Which of the above statement(s) is/are correct?
Explanation
This program is dedicated to improving maternal health and infant nutrition by providing financial incentives to pregnant women. The assistance is tied to specific health-seeking behaviors, such as attending prenatal check-ups and completing necessary vaccinations. By focusing on these critical periods, the scheme aims to reduce maternal mortality and ensure that children are born with a healthy weight.
Q9034. The characteristic shrink-swell behavior of the black soils in the Kota and Bundi districts is primarily due to the dominance of which clay mineral?
Explanation
The shrink-swell behavior characteristic of black soils in Kota and Bundi is caused by the dominance of the montmorillonite clay mineral. This specific type of silicate clay has a lattice structure that expands when water enters the layers and contracts upon drying. This mineralogical property is responsible for the deep cracks and the high plasticity observed in these heavy soils.
Q9035. Which scheme ensures the distribution of subsidised food grains to the economically disadvantaged sections of society?
Explanation
Ensuring that no citizen suffers from hunger is a priority of this food security initiative. It provides essential food grains at highly subsidized prices to those in need, serving as a critical buffer against poverty and food price inflation. This program is a key part of the state’s broader strategy to eliminate malnutrition and provide basic sustenance to all.
Q9036. Which of the following pairs of soil type and its highly suitable commercial crop in Rajasthan is incorrectly matched?
Explanation
While black soils are excellent for cotton and soybean, and desert sandy soils support hardy crops like moth bean, the pairing of red loam soil with sugarcane is traditionally incorrect for Rajasthan. Red loams in the south are better suited for maize. Sugarcane typically requires deeper, more fertile alluvial or heavy soils with very high water availability and nutrient levels.
Q9037. Read the following statements about the Mukhyamantri Nishulk Dawa Yojana:
I. It significantly reduces the out-of-pocket expenditure of patients.
II. It provides essential medicines free of cost at government health institutions.
III. It is available only to those living below the poverty line (BPL).
IV. It relies on a centralized procurement system to ensure drug availability.
Which of the above statement(s) is/are correct?
I. It significantly reduces the out-of-pocket expenditure of patients.
II. It provides essential medicines free of cost at government health institutions.
III. It is available only to those living below the poverty line (BPL).
IV. It relies on a centralized procurement system to ensure drug availability.
Which of the above statement(s) is/are correct?
Explanation
This healthcare initiative ensures that essential medicines are available free of charge at all government health facilities. By using a centralized procurement system, the state maintains a steady supply of high-quality drugs, significantly reducing the medical expenses of patients. This program is open to all patients, helping to make quality healthcare accessible and affordable for the entire population.
Q9038. Saline and alkaline soils in Rajasthan are defined pedologically by the presence of:
Explanation
In Rajasthan, saline and alkaline soils are pedologically defined by the excessive accumulation of soluble salts, including sodium chlorides and sulfates. These salts often form a white crust on the surface. These conditions typically arise in areas with poor drainage and high evaporation rates, leading to chemical imbalances that hinder plant growth and degrade the overall productive capacity of the land.
Q9039. Which of the following pairs is correctly matched?
Explanation
Providing free diagnostic services is a crucial component of modern public healthcare management. This scheme allows patients to access expensive laboratory tests and imaging services without paying any fees at government medical centers. By removing the financial barriers to accurate diagnosis, the initiative ensures that diseases are detected early and patients can receive timely and effective medical treatment.
Q9040. Consider the following conditions:
I. Faulty agricultural practices and over-irrigation
II. High rate of evaporation in arid climates
III. Inadequate surface and subsurface drainage
IV. Capillary upward movement of water
V. Heavy application of organic farmyard manure
Which combination of the above contributes significantly to the development of soil salinity in Rajasthan?
I. Faulty agricultural practices and over-irrigation
II. High rate of evaporation in arid climates
III. Inadequate surface and subsurface drainage
IV. Capillary upward movement of water
V. Heavy application of organic farmyard manure
Which combination of the above contributes significantly to the development of soil salinity in Rajasthan?
Explanation
The development of soil salinity in Rajasthan is driven by several presidential factors, including faulty agricultural practices and over-irrigation. High evaporation rates in arid climates cause dissolved salts to rise through capillary action. When coupled with inadequate surface and subsurface drainage, these salts accumulate in the topsoil. While organic manure is beneficial, these other physical and climatic factors are the primary drivers.Answer key for these questions
