1、Improving crop drought resistance with plant growth regulators and
In this review, we summarize these two strategies reported in recent studies, focusing on the mechanisms by which these exogenous treatments regulate crop drought resistance. Finally, future challenges and directions in crop drought resistance breeding are discussed.
2、Effects of Foliar Fertilization: a Review of Current Status and Future
Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.
3、Foliar Fertilization: An Approach To Enhance Nutrient Use Efficiency
Observed effects of foliar fertilization included yield increases, resistance to diseases and insect/pests, improved drought tolerance and enhanced crop quality.
4、Foliar application of trace elements in alleviating drought stress
In such circumstances, foliar application of mineral nutrients is more effective than application of fertilizers directly in soil. Rapid absorption of nutrients by leaf tissues and a direct application to the site of demand makes this method faster.
Potential Foliar Chemicals for Enhancing Yield and Drought Tolerance in
In pulse crops, synchronized flowering altered the source-sink relationship due to the rapid translocation of nutrients from leaves to the developing pods. Additional nutrition through foliar...
Foliar nutrition: Potential and challenges under multifaceted
The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.
Biofertilizers as an eco
Natural compounds effectively alleviated drought stress. These eco-friendly agents act by modulating different physiological, biochemical and molecular facets. Drought is a severe abiotic stress adversely affecting agricultural activity worldwide.
Foliar nitrogen and phosphorus fertilization
Foliar fertilization is more demanding with respect to technical knowledge and management skills than is the conventional use of solid fertilizers. If not carried out appropriately, foliar fertilization with nitrogen or phosphorus will imply a considerable risk of causing negative yield responses.

However, under certain circumstances, foliar fertilization is more economic and effective. Foliar symptoms, soil and plant tissue tests, and crop growth responses are principal nutrient disorder diagnostic techniques.
Foliar Spray of Fe
Foliar fertigation of both levels of Fe-Asp was found more effective for improvement of all studied growth attributes of water-stressed sunflower plants, in comparison with both levels of FeSO 4.
Drought resistance agents and foliar fertilizers are two commonly used plant nutrient supplements that play important roles in agricultural production. their effects and suitable application scenarios differ.
First, it is essential to clarify that each type of fertilizer has specific functions, and neither can be simply deemed superior. When selecting fertilizers, factors such as crop growth stages, soil conditions, and climatic environments must be comprehensively considered.
1. Function of Drought Resistance Agents:
Drought resistance agents are designed to enhance plants' ability to withstand drought. Their primary role is to help plants maintain normal physiological activities under dry conditions, reducing the negative impacts of water stress. These agents often contain ingredients that improve plant stress resistance, such as alginic acid and humic acid. These components can modify soil structure, increase water retention capacity, and thereby boost plants' resilience to drought.
2. Function of Foliar Fertilizers:
Foliar fertilizers are sprayed directly onto plant leaves to provide essential nutrients and promote growth. They typically contain readily absorbable nutrients like nitrogen (N), phosphorus (P), and potassium (K). Through foliar application, these fertilizers quickly supply nutrients to plants, accelerating growth rates and increasing yields.
3. Comparative Effectiveness:
From the perspective of enhancing drought resistance, drought resistance agents outperform foliar fertilizers. Ingredients like alginic acid and humic acid improve soil structure and water retention, directly mitigating water stress. In contrast, while foliar fertilizers deliver essential nutrients, they do not address soil structure issues, resulting in weaker drought resistance benefits.
foliar fertilizers may offer advantages in specific situations. For instance, when soil quality is poor or environmental conditions are harsh, foliar fertilizers can rapidly provide nutrients to stressed plants. Additionally, they have practical benefits, such as ease of use and faster results.
Both drought resistance agents and foliar fertilizers have distinct advantages. The choice depends on factors like crop growth stages, soil conditions, and climate. Drought resistance agents are preferable for improving drought tolerance in challenging soils or climates, while foliar fertilizers are ideal for rapid nutrient supplementation and growth promotion. Regardless of the option selected, proper application methods are critical to maximizing effectiveness.
