Study Notes

Cropping Pattern vs Cropping System

Cropping pattern refers to the types and arrangement of crops over time and space.
Cropping pattern considers the proportion of land dedicated to specific crops at a given time.
It involves the yearly sequence and spatial arrangement of crops and fallow periods.
Factors influencing a cropping pattern include climate (rainfall, temperature), soil type, and available technology.
Cropping systems are a combination of cropping patterns and management practices designed to maximize benefits from available resources.
The goal of a cropping system is to efficiently utilize resources such as land, water, and solar energy.
A cropping system aims to maintain production stability and achieve higher returns.

Mono cropping

Growing the same crop or a single crop on the same land year after year.
Results in a 100% cropping intensity.
Merits:
- Produces higher quantities of specific crops.
- Improves efficiency in farming operations.
- Simplifies management procedures.
- Potentially generates higher earnings.
Demerits:
- Increased susceptibility to widespread crop failures.
- Reduces biodiversity in the agricultural ecosystem.
- Increases vulnerability to harmful organisms (pests and diseases).
- Continuous use of the same soil can lead to disease and pest build-up.
- Soil degradation can occur, rendering land unusable.

Multiple Cropping

Cultivating two or more crops on the same field within a year.
Intensifies cropping in both time and space.
Merits:
- Maintains soil vigor and fertility, supporting long-term crop growth.
- Promotes efficient utilization of resources like fertilizers and moisture, resulting in optimal productivity.
- Effectively controls weed growth.
- Reduces the incidence of pest and disease attacks.
- Decreases the risk of economic loss due to crop failure.
- Provides additional income for farmers.
- Contributes to nutrient diversity in the farmers' food sources.
- Helps control soil erosion.
Demerits:
- Large-scale mechanization is challenging as different machinery is required for different crops.
- Intercultural operations like weeding, manuring, fertilizing, and irrigation become more complex in intercropping systems.
- The incidence of pest and disease attacks can increase if suitable alternate hosts are present.

Multiple Cropping Types

Intercropping
- Two or more crops are grown simultaneously on the same land.
- Aims to effectively utilize space and resources.
- Types of intercropping:
  - Row intercropping
  - Patch intercropping
  - Strip intercropping
  - Multi-storied intercropping
  - Alley intercropping
Characteristics of a good intercrop:
- It should not negatively impact the growth and yield of the main crop.
- It should mature earlier or later than the main crop.
- Ideally, it should be a legume crop to maintain soil fertility and productivity.
- It should have different growth habits and nutrient requirements.
- It should have different rooting depths.
- It should differ in canopy development and sunlight requirements.
Mixed cropping
- Seeds of different crops are mixed together and broadcasted.
- Several crops are cultivated simultaneously on the same land without a fixed row pattern.
- The main objective is to minimize the risk of total crop failure and provide farmers with food and fodder security.
- Key differences between intercropping and mixed cropping:
  - Intercropping aims to utilize space efficiently, while mixed cropping is focused on risk reduction.
  - Intercropping uses specific planting patterns, while mixed cropping has no fixed planting pattern.
  - Separate fertilizers and pesticides are used for different crops in intercropping, but the same inputs are used for all crops in mixed cropping.
Relay cropping
- Two or more crops are grown simultaneously during their respective life cycles.
- The succeeding crop is planted before harvesting the preceding crop.
- The second crop is planted after the first has reached its reproductive stage but before harvest.
- Examples: potato planted before maize harvest and radish planted before potato harvest.
Sequence/Sequential cropping
- Two or more crops are grown in quick succession on the same land in a single farming year.
- Sowing the succeeding crop and harvesting the preceding crop occur almost simultaneously or in close succession.
- No overlapping occurs between the cropping cycles.
- Example: After maize harvest, potato is sown, and chili is sown after potato digging.
- Types:
  - Double cropping: Two crops are grown sequentially in a year.
  - Triple cropping: Three crops are grown sequentially in a year.
  - Quadruple cropping: Four crops are grown sequentially in a year.
  - Ratoon cropping: Cultivating regrowth after harvest.

Cropping Intensity

The ratio of total cropped area to the total farm area in a year, expressed as a percentage.
Calculated as: (Actual cropped area / total farm area) * 100.
Example: If a farmer has 20 hectares of land, and 18 hectares are cropped in one season and 12 in another, the cropping intensity is (18 + 12) / 20 * 100 = 150%.

Land Equivalent Ratio (LER)

Represents the relative land area needed under sole cropping to produce the yield achieved through intercropping.
Calculated as: (Yield of base crop in intercropping / Yield of base crop in sole cropping) + (Yield of intercrop in intercropping / Yield of intercrop in sole cropping).
LER > 1 indicates a benefit from intercropping, while LER < 1 suggests a disadvantage.
