Potatoes are a critical global crop, with annual production reaching 375 million tons (FAO, 2023). As water scarcity and climate variability challenge agricultural productivity, efficient irrigation methods like drip systems are becoming essential for sustainable farming.
Rivulis Trials: Methodology and Key Findings
The trials compared drip irrigation (Rivulis system) against conventional sprinkler irrigation in two distinct settings:
- Spring Trial: Sandy soil irrigated with river water.
- Winter Trial: Clay soil irrigated with drilled well water.
Both trials used the same potato varieties (‘Vogue’ and ‘Liseta’) destined for the fresh market.
Spring Trial Results
- Total yield: 53 tons/ha (vs. regional average of 45 tons/ha).
- Drip vs. Sprinkler:
- Higher marketable yield (more uniform tuber size).
- Larger average potato weight (improved quality).
- 18% less water used compared to sprinklers.
Winter Trial Results
- Drip outperformed sprinklers in total and marketable yield.
- 40% less water used—a critical advantage in water-scarce regions.
Why Drip Irrigation Wins
The trials confirm that drip irrigation:
✔ Increases yield and marketability (better uniformity, fewer rejects).
✔ Slashes water use (18-40% savings).
✔ Works across seasons and soil types (sandy & clay).
✔ Improves input efficiency (less fertilizer leaching, precise delivery).
A Sustainable Future for Potato Farming
With global water stress threatening agriculture, Rivulis’ drip irrigation offers a proven solution—boosting yields while conserving resources. Farmers, agronomists, and policymakers must prioritize such technologies to ensure food security and climate resilience.
