1、Full article: Potato yield response to foliar application of phosphorus as affected by soil moisture and available soil phosphorus
Plant dry matter yields, P-accumulation and phosphorus use efficiency (PUE) with or without foliar application were determined at five soil P-levels in combination with two soil moisture levels.
2、Phosphorous and Foliar Applied Nitrogen Improved Productivity and Quality of Potato
This study was therefore planned to evaluate the effect of soil applied phosphorus (DAP) and foliar application of nitrogenous fertilizer (urea) on growth, yield and quality of potato.
3、EFFECT OF FOLIAR FERTILIZERS ON PHYSIOLOGICAL CHARACTERISTICS OF POTATO
The experiment with three commercial foliar fertilizers (EPSO Microtop, Drin, Megagreen) and control treatment (without foliar fertilizer) was arranged in a randomized complete block design with three replications.
4、The Effect of Foliar Fertilization on the Yield and Quality of Different Crops
To avoid these complications, preventive foliar fertilization can be useful, specially for varieties with a high potential of yield and quality, and in climatically suboptimal years.

Hutchinson et al. (2002) concluded that to optimize fertilizer use efficiency of potato, the nutrient released from fertilizers should be low early in the season and increase through full flowering and into bulking before tapering off.
Impact of Nitrogen Fertilizer and Foliar Spray of Selenium on Growth, Yield and Chemical Constituents of Potato plants
Therefore the present investigation aimed to study the response of Potato (Solanum tuberosum L.) to nitrogen fertilizer and foliar spray of Selenium on the vegetative growth, tuber yield and chemical composition.
Effect of Phosphorus and Potassium Fertilizer Rates on Yield and Yield Component of Potato (Solanum tubersum L,) at K/Awlaelo, Tigray, Ethiopia
A study was conducted to evaluate the effect of phosphorous and potassium fertilizer rates on the yield and yield components of potato (Solanum tuberosum L.) grown on sandy clay loam soils of K/Awlaelo Wereda, Tigray, Ethiopia during 2012 rainy season.
Influence of Source and Time of Potassium Application on Potato Growth, Yield, Economics and Crisp Quality
Net income and benefit:cost ratio were highest for K-chloride followed by K-sulphate and lowest for K-nitrate. The study suggests that for crisping potatoes, K-sulphate is more suited than K-chloride, as it not only increased tuber dry-matter percentage and crisp yield, but also decreased crisp oil percentage.
Nanotechnology promotes the R&D of new
The new screening criteria of new-generation micronutrient foliar fertilizers have been put forward from the viewpoints of material engineers, and our recent research efforts using nanotechnology to design and develop new foliar fertilizers have been summarised.
Effect of humic acid multinutrient fertilizers on yield and nutrient use efficiency of potato: Journal of Plant Nutrition: Vol 39 , No 7
A field experiment was conducted to study the effect of humic acid multinutrient fertilizers like Grow Flow 45H and HA-NPK complex on crop yield, nutrient content and uptake, and nutrient use efficiency of potato.
When applying foliar fertilizers to enhance potato yields, it is crucial to select products suited to local climate and soil conditions while paying attention to timing and application methods. Here are some recommendations:
-
Select Appropriate Foliar Fertilizers: Choose fertilizers based on the potato’s growth stage, soil environment, and weather. For example:
- Early growth stage: Use compound fertilizers rich in nitrogen (N), phosphorus (P), and potassium (K) to promote seedling development.
- Mid-growth stage: Opt for foliar sprays containing microelements (e.g., zinc, magnesium) to support flower bud differentiation and blooming.
- Pre-harvest stage: Apply organic-rich fertilizers (e.g., humic acid or fish hydrolysate) to improve tuber quality and yield.
-
Timing of Application: Adjust spraying schedules according to growth phases:
- Seedling stage: Use "early-stage" fertilizers to boost root and shoot development.
- Flowering stage: Apply "mid-stage" fertilizers to enhance flowering and nutrient uptake.
- Tuber formation stage: Use "late-stage" formulas to stimulate tuber enlargement and final yield.
-
Application Methods: Tailor spraying techniques to the fertilizer type and crop stage:
- Ensure even coverage on leaves, avoiding overapplication to prevent burn.
- Water-soluble fertilizers: Dilute directly with water.
- Oil-based formulations: Mix with water first, then add vegetable oil before dilution.
- Powder formulations: Combine with water and add syrup or honey to improve adhesion.
-
Dosage Adjustment: Modify application rates based on growth phases:
- Early stages: Apply lower doses to avoid stunting growth.
- Mid to late stages: Gradually increase dosage to meet rising nutrient demands.
-
Key Precautions:
- Spray on sunny, windless days to maximize absorption.
- Avoid midday heat to reduce evaporation and leaf damage.
- Target the underside of leaves for better penetration.
- Follow a "light but frequent" approach to prevent over-concentration.
For optimal results, combine different foliar fertilizers at specific growth stages, adhere to proper application techniques, and monitor plant responses and soil moisture. Adjust strategies as needed to achieve higher yields.
