Blue and yellow shade nets enhance fig fruit nutrient density and extend shelf life

Utilizing photoselective shade nets in specific colors can significantly improve the nutritional content of figs and prolong their postharvest quality.

Horticulturae · 2021

Key Findings

01Blue shade nets resulted in the highest nitrogen content in 'Sabz' cultivar figs.
02Color nets (blue and yellow) increased calcium concentration in 'Siah' cultivar figs.
03Yellow shade nets increased magnesium content in 'Siah' and phosphorus content in 'Sabz' cultivar figs.
04Photoselective nets positively affected postharvest quality by reducing fruit weight loss and extending shelf life.

Application

Design takeaway

How to apply

When designing agricultural systems or developing new produce, consider how light filtration through colored materials can be used to achieve specific nutritional profiles or extend shelf life.

Project actions

01When researching materials for agricultural applications, consider their optical properties and how they interact with light.
02Investigate how different light spectra affect plant growth and fruit quality for your design project.

Method & Evidence

AimTo investigate how different colored shade nets (blue and yellow) influence the mineral nutrient composition and postharvest shelf life of two fig cultivars under rain-fed conditions.

MethodExperimental research

ProcedureFig trees of two cultivars ('Sabz' and 'Siah') were subjected to three light conditions: blue shade net, yellow shade net, and no shade (control). The experiment was conducted under rain-fed conditions and arranged in a randomized complete block design with three replications. Mineral element analysis of the fruit, fruit weight loss, and shelf life were measured.

ContextHorticulture, agricultural technology, postharvest management

Variables

IVColor of shade net (blue, yellow, none)

DVMineral element content (N, Ca, Mg, P), postharvest shelf life, fruit weight loss

CVFig cultivar ('Sabz', 'Siah'), rain-fed conditions, randomized block design, replication

Strengths & Limitations

Strengths

+Investigates a novel application of shade nets beyond simple light reduction.
+Includes analysis of both fruit quality and postharvest performance.

Limitations

The cost and availability of specific colored nets, as well as potential impacts on other plant growth factors not studied here, are practical limitations.

Reliability & validity

The use of a randomized complete block design with replications enhances the reliability and validity of the findings by minimizing bias and accounting for environmental variability.

Think critically

Beyond nutritional enhancement and shelf life, what other potential benefits or drawbacks might arise from using colored shade nets on crops, considering factors like pest resistance, water retention, or overall plant health?

Design Principles

"Light spectrum manipulation through photoselective materials can be leveraged to enhance the nutritional and shelf-life characteristics of agricultural products."

This research introduces an innovative agro-technological approach that directly impacts product quality and marketability. By manipulating light spectrum with colored nets, growers can enhance the intrinsic value of their produce, potentially commanding premium prices and reducing post-harvest losses, thereby improving profitability.

What This Means for Your Design

Putting blue or yellow covers over fig trees can make the fruit have more nutrients and stay fresh for longer after picking.
