Article Synopsis
- Some strategies can enhance water usage in crops facing deficit by improving yields and reducing evapotranspiration (ET) to support sustainable production systems.
- Four experiments were conducted in the Brazilian semi-arid region to assess the effects of spacing, planting orientation, nitrogen fertilization, and intercropping on water dynamics for forage cactus and cactus-sorghum intercropping.
- Results showed that intercropping significantly boosted water productivity (by 130%), while certain nitrogen levels reduced ET but caused higher deep drainage losses; optimized practices included specific spacings and orientations for better water use efficiency.
