Intercropping: Growing of two or more crops simultaneously on the same piece of land (field). There is a crop intensification in both time and space dimensions. There is intercrop competition during all or part of crop growth.
Type of intercropping:
1. Mixed intercropping
2. Row intercropping
2. Strip intercropping
4. Relay intercropping
Definitions of Intercropping system:
1. Mixed Intercropping: Growing two or more crops simultaneously with no district row arrangement.
2. Row Intercropping: Growing two or more crops simultaneously where one or more crops are planted in rows.
3. Strip Intercropping: Growing soil conserving and soil depleting crops in alternate strips running perpendicular to the slope of the land or to the direction of prevailing winds for the purpose of reducing errosion.
4. Relay Intercropping: Seeding planting two or more succeeding crops after flowering and before the harvest of the standing crop.
Advantages:
1. Intercropping gives higher income per unit area than sole cropping.
2. It acts as an insurance against failure of crop in abnormal year.
3. Intercrops maintain soil fertility as the nutrient uptake is made from both layers.
4. Reduce soil runoff.
Limitations: Intercropping system is uneconomical and undesirable during rabi.
Crops to be considered for intercropping.
A) Kharif crops:
1. Medium black soils:
a) Pearl millet + Red gram 2: 1
b) Pearl millet + Horse gram / Kidney bean / cow pea Inter row of pearl millet.
3. Soils up to 20 cm depth
a) Pearl millet + red gram (30 - 60 - 30 cm)
B) Rabi crops:
Safflower + Gram (2: 1)
D) Fodder for milch animals: Sorghum bajara + Cowpea or horse gram or kidney bean.
