FERTIGATION A Nutrient

Using fertigation to eficiently deliver water and nutrients at the same time to exactly where they are needed can reduce the volume of water used compared to conventional agricultural systems and can achieve up to 90 percent water use eficiency.

Fertigation: An Effective Tool For Enhancing Water and Nutrient Use

What is fertigation? The technique of fertigation was first observed in late 1960s in Israel. Fertigation is the use of combination of drip irrigation and fertilizers to create a controlled nutrient release system resulting in significantly lower leaching losses of nutrie. ts while meeting.

The fruit set period is a critical stage in fruit tree growth, determining both yield and fruit quality. During this phase, trees have heightened nutritional demands, making rational fertilization essential to improve fruit retention, promote development, and enhance quality. Water-soluble fertilizers (WSFs) are efficient and eco-friendly options ideal for this stage. Below are key recommendations for applying WSFs during fruit set:

1. Understand Variety-Specific Traits Different fruit tree varieties require distinct nutrients. Before fertilization, identify the nutritional needs of your specific variety. Generally, fruit set demands higher levels of nitrogen (N), phosphorus (P), and potassium (K), along with microelements like iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu).

2. Select Appropriate WSFs Choose formulations based on tree variety and soil conditions. Common WSFs include urea, monoammonium phosphate, and NPK blends. High-nitrogen formulas support flower bud differentiation and fruit enlargement, while low-nitrogen options enhance coloration and maturation.

3. Timing Fruit set typically occurs in spring, varying by region and climate. Apply WSFs 20–30 days post-flowering, when trees transition to the reproductive phase and nutrient demand peaks.

4. Application Methods

   • Foliar Spraying: Dilute WSFs and spray directly onto leaves for rapid absorption. Avoid overapplication to prevent foliar damage.
   • Root-Zone Drench: Dissolve WSFs in water and irrigate the root zone. This minimizes nutrient loss but requires careful dosing to avoid root burn.

5. Dosage Apply 5–10 kg/mu (or adjust based on soil tests and tree age). Over-fertilization risks salt buildup and root injury.

6. Frequency Administer 2–3 applications at 7–10-day intervals:

   • First: Base nutrient supply.
   • Second: Supports flowering and early fruiting.
   • Third: Aids fruit expansion and ripening.

7. Monitor Effects Regularly test soil nutrients and observe tree health. Soil analysis and visual assessments of growth help refine fertilization plans.

8. Precautions

   • Avoid mixing WSFs with alkaline substances, which reduce efficacy.
   • Prevent overdosing to mitigate soil salinization and root damage.

9. Disease and Pest Control During fruit set, prioritize integrated pest management (IPM) using biological, physical, or targeted chemical controls. Minimize ecological disruption by balancing fertilizer and pesticide use.

10. Holistic Management Complement fertilization with pruning, thinning, and disease prevention. A synergistic approach ensures optimal yields and fruit quality.

By tailoring WSF applications to variety traits, phenological stages, and environmental factors, growers can maximize productivity while fostering sustainable orchard practices.
