Short Summary

This study develops and validates differentiated irrigation schedules based on plant evapotranspiration and critical water stress to manage climate risks in agriculture. It demonstrates that these schedules can save 20% of irrigation water while increasing crop yields by 15–20% for cabbage and apple seedlings.

Objective

• To develop and validate scientifically based (differentiated) irrigation schedules that optimize water use according to plant development phases and critical water stress, aiming to save irrigation water and increase crop yields under climate change risks.

Study Configuration

• Spatial Scale: Experimental plots (using lowland peat substrate for cabbage seedlings and sandy soil for apple seedlings), Michurinsky Garden of the Russian State Agricultural Academy named after K.A. Timiryazev.
• Temporal Scale: Growing season, seedling period (cabbage), 1st, 2nd, and 3rd years of life (apple seedlings).

Methodology and Data

• Models used: Not explicitly stated as a simulation model. The study utilizes a conceptual framework for "scientifically based irrigation regimes" and references theoretical approaches for evapotranspiration calculation (e.g., Konstantinov's formula).
• Data sources: Experimental field measurements (evapotranspiration determined by the weight method, yield, root system development), long-term experiments, and literature review (e.g., FAO, ICID data for global agricultural trends).

Main Results

• Differentiated irrigation schedules, tailored to plant development phases and evapotranspiration, resulted in a 20% saving in irrigation water compared to generally accepted schedules.
• These schedules led to a 15–20% increase in yield for white cabbage (variety “Number one Gribovsky 147”) and apple seedlings.
• For cabbage seedlings, the differentiated schedule involved reducing pre-watering soil moisture to 40-50% FC in early stages (seedlings – 2-3 leaves), increasing it to 50-60% FC (2-3 to 4 leaves), and further to 60-80% FC (4-6 leaves).
• For apple seedlings, the differentiated regime maintained 70-90% FC in the 1st year and 60-80% FC in the 2nd and 3rd years, with the depth of moisture increasing from 30 cm to 50 cm.
• Reduced soil moisture in non-critical periods (e.g., early vegetative stage) was shown to reduce moisture loss by evaporation from the soil surface and promote better root system development.
• Maintaining soil moisture below 100% FC prevented infiltration of irrigation water to underlying horizons, particularly in light sandy soils, and reduced disease development in cabbage seedlings.

Contributions

• Development and experimental validation of specific differentiated irrigation schedules for white cabbage and apple seedlings, demonstrating quantifiable benefits in water saving and yield increase.
• Emphasizes the integration of plant ontogenesis, critical water stress, and evapotranspiration dynamics into practical, resource-saving irrigation management.
• Highlights the potential of precision irrigation, including remote-controlled drip irrigation systems, to enhance water-saving effects and optimize resource utilization in agriculture.
• Provides a practical framework for implementing environmentally sound irrigation strategies to mitigate climate change risks and enhance food security.
