The GCA of an irrigation canal is 50000 hectares out of which 80% is CCA. If the intensity of irrigation for Rabi season is 60% and for Kharif season is 20%, then the crop ratio will be

Concept:

The crop ratio is calculated as the ratio of the area under cultivation for the Rabi season to the area under cultivation for the Kharif season. It helps in understanding the distribution of water and cultivation patterns between different crop seasons.

Calculation:

Given:

• Gross Command Area (GCA) = 50,000 hectares
• Culturable Command Area (CCA) = 80% of GCA
• Intensity of irrigation for Rabi season = 60%
• Intensity of irrigation for Kharif season = 20%

1. Calculate the Culturable Command Area (CCA):

\( \text{CCA} = 0.8 \times \text{GCA} \)

\( \text{CCA} = 0.8 \times 50,000 \, \text{hectares} \)

\( \text{CCA} = 40,000 \, \text{hectares} \)

2. Calculate the area irrigated during the Rabi season:

\( \text{Area for Rabi} = \text{Intensity of irrigation for Rabi} \times \text{CCA} \)

\( \text{Area for Rabi} = 0.6 \times 40,000 \, \text{hectares} \)

\( \text{Area for Rabi} = 24,000 \, \text{hectares} \)

3. Calculate the area irrigated during the Kharif season:

\( \text{Area for Kharif} = \text{Intensity of irrigation for Kharif} \times \text{CCA} \)

\( \text{Area for Kharif} = 0.2 \times 40,000 \, \text{hectares} \)

\( \text{Area for Kharif} = 8,000 \, \text{hectares} \)

4. Calculate the Crop Ratio:

\( \text{Crop Ratio} = \frac{\text{Area for Rabi}}{\text{Area for Kharif}} \)

\( \text{Crop Ratio} = \frac{24,000}{8,000} \)

\( \text{Crop Ratio} = 3 \)
