Attempt all the questions:
Q1. Define rainfed
farming and write its characteristics. Explain the detrimental effects of
unfavourable weather conditions on rainfed farming.
Rainfed
farming, also known as dryland farming or rainfed agriculture, is a type of
agricultural practice that relies predominantly on rainfall for water supply
rather than irrigation. It is commonly practiced in regions where irrigation
infrastructure is limited or non-existent, and where precipitation is the
primary source of moisture for crop growth. Here are some characteristics of
rainfed farming:
Reliance on
Rainfall: Rainfed farming depends on the natural precipitation patterns in a
region. Farmers do not have control over the timing, intensity, or distribution
of rainfall.
Climate
Sensitivity: Rainfed agriculture is highly sensitive to climatic variations.
Changes in rainfall patterns, temperature extremes, and other climatic factors
can significantly impact crop yields.
Risk and
Uncertainty: Since rainfall is unpredictable, rainfed farming is associated
with higher levels of risk and uncertainty compared to irrigated agriculture.
Crop failures due to droughts or erratic rainfall can lead to economic losses
for farmers.
Water
Conservation: In rainfed farming, water conservation practices are crucial for
maximizing water use efficiency. Techniques such as mulching, contour farming,
and rainwater harvesting are often employed to minimize water loss through
evaporation and runoff.
Crop Selection:
Farmers in rainfed areas typically choose crops that are well-adapted to the
local climate and require less water. Drought-resistant crop varieties and
traditional rainfed crops are commonly cultivated.
Soil
Conservation: Soil erosion is a major concern in rainfed farming due to the
reliance on natural rainfall. Soil conservation measures like terracing,
contour plowing, and cover cropping are implemented to prevent soil degradation
and erosion.
Limited
Infrastructure: Rainfed farming areas often lack proper irrigation
infrastructure, such as dams, canals, and wells. This limits the availability
of water for agricultural activities and increases dependence on rainfall.
Drought:
Extended periods of drought can lead to water stress, reduced crop yields, and
even crop failure. Droughts deprive crops of essential moisture, stunting
growth and development.
Floods: Intense
rainfall events can cause flooding in rainfed farming areas, resulting in soil
erosion, waterlogging, and damage to crops. Floods can wash away topsoil and
nutrients, reducing soil fertility and productivity.
Erratic
Rainfall: Inconsistent rainfall patterns, including late onset or early
cessation of rains, can disrupt crop planting schedules and growth cycles.
Erratic rainfall can lead to uneven germination, poor crop establishment, and
yield losses.
Extreme
Temperatures: Extreme temperatures, such as heatwaves or cold snaps, can stress
crops and impair their growth. Heat stress can cause wilting, leaf scorching,
and reduced photosynthesis, while frost damage can kill or injure sensitive
crops.
Pests and
Diseases: Unfavorable weather conditions can create conducive environments for
pests and diseases to thrive. Increased humidity, warm temperatures, and
waterlogged soils can exacerbate pest and disease pressures, leading to crop
damage and yield losses.
Q2. What is the
management practices for aberrant weather conditions (local and improved), explain?
Q3. What is crop
diversification? Describe the suggested crop diversification in rainfed regions
of India.
Q4. Describe the
on-field water conservation.
Q5. Explain sprinkler
irrigation method. Discuss the advantages and disadvantages of sprinkler irrigation.
