1、Fawzy, Z.F., Behairy, A.G. and Shehata, S.A. (2005) Effect of potassium fertilizer on growth and yield of sweet pepper plants (Capsicum annuum, L
ABSTRACT: Irrigation with high salinity water influences plant growth, production of photosynthetic pigments and total phenols, leading to reduction in crop yield and quality. The objective of this study was to investigate the effects of potassium (K) foliar application in mitigating the negative ...
2、Potassium for better crop production and quality
Among many factors, an adequate and well balanced nutrition with mineral nutrients is a fundamental issue in achieving a high crop production and a better quality in practical agriculture.
3、Mineral sources of potassium for plant nutrition. A review
In this context it is appropriate to review current knowledge of alternative sources of K, which is the seventh most abundant element in the Earth’s continental crust, present in feldspars and (much less commonly) feldspathoid minerals including nepheline and leucite.
Liquid fertilizer production by alkaline hydrolysis of carcasses and the evaluation of developed fertilizer in hot pepper cultivation
In this study, the injected bacteria during the process of composting liquid fertilizer from the hydrolyzed solution of pig carcasses possibly acted as plant-growth promoting bacteria, but the promotion of crop growth was not observed in hot pepper growth.
The effects of potassium fertilization on water‐use efficiency in crop plants
The application of K fertilizer to plants is a simple agronomic practice used to increase crop tolerance to a temporary water shortage.
Effect of N and K Fertilizers on Yield and Quality of Greenhouse Vegetable Crops
A fixed field experiment was designed to study the effects of nitrogen (N) and potassium (K) fertilizers applied to optimize the yield and quality of typical vegetable crops. Application of N and K fertilizers significantly increased the yields of kidney bean.
Impacts of long
Crop yields in all the treatments with P fertilizer were significantly higher than those in N alone and CK treatments in both long-term experiments, suggesting that P fertilizer had a greater contribution in improving crop yield than N fertilizer after long-term lack of K fertilization.
Potential of industrial de
Potassium is a valuable element because it is an essential nutrient for plant growth. To avoid yield losses in agricultural production, potassium fertilizer has to be spread on the soil (Hopkins and Hüner, 2009).
Effects of Different Organic Fertilizers on Growth, Yield and Quality of Capsicum Annuum L. Var. Kulai (Red Chilli Kulai) – Biosciences Biotechnology
From this study, the best of organic treatment can be determined for optimum growth, yield and quality of chilli. Farmers may use those treatments as an alternative ways in order to avoid excessive application of chemical fertilizer to the soil.
Effects of the applications of phosphorus and potassium fertilizers at different growth stages on the root growth and bioactive compounds of Salvia
Here, we conducted a 2-year greenhouse experiment to investigate the effects of applying phosphorus (P) and potassium (K) fertilizers at different growth stages on root growth and production of bioactive compounds in S. miltiorrhiza.
Hot peppers, also known as chili peppers or Capsicum annuum, are widely cultivated as both a vegetable and a spice. The use of potassium fertilizer plays a critical role in their cultivation, as it enhances disease resistance, promotes fruit development, and improves quality. Below is a detailed analysis of the optimal potassium fertilizer choices for growing hot peppers:
I. Selecting the Right Type of Potassium Fertilizer
-
Potassium Sulfate This is a common inorganic potassium fertilizer that effectively promotes plant growth. It improves soil permeability, enhances water absorption by roots, and stimulates root development. Additionally, potassium sulfate aids in nitrogen uptake, boosts photosynthetic efficiency, and supports overall crop growth.
-
Potassium Chloride Compared to potassium sulfate, potassium chloride has a higher potassium content but poorer water solubility, requiring dilution before use. It is suitable for soils with poor drainage or high salinity, as it improves soil structure, reduces salt accumulation, and increases yield and quality.
-
Potassium Nitrate A compound fertilizer containing nitrogen, phosphorus, and potassium, potassium nitrate provides balanced nutrients tailored to different growth stages. Its fast-acting and long-lasting effects accelerate crop growth and boost productivity.
II. Application Methods
-
Base Fertilization Prior to planting, apply potassium fertilizer as a base application, mixed with organic materials like chicken manure or cow manure. This ensures a steady release of nutrients throughout the crop’s lifecycle.
-
Topdressing During growth, apply additional potassium based on plant health and soil tests. Dissolve the fertilizer in water for irrigation or mix it with soil. Topdressing should coincide with peak growth stages to maximize results.
-
Foliar Spraying For potassium-loving crops like hot peppers, foliar spraying during vigorous growth can supplement nutrient intake. avoid excessive concentrations to prevent leaf damage.
III. Key Considerations
-
Soil Conditions Match fertilizer type to soil pH and texture. For acidic soils, prefer potassium sulfate or chloride; for alkaline soils, use potassium nitrate. Avoid high-concentration potassium in saline-prone soils to prevent salinization.
-
Dosage Apply 5-10 kg per mu (approx. 0.7-1.5 lbs per 100 sq ft) of potassium fertilizer, adjusted for crop variety, soil fertility, and climate. Excessive use may lead to overgrowth, reducing yield and quality.
-
Timing Base fertilization before planting ensures sustained nutrient supply. Topdress during peak growth phases for rapid uptake.
Using potassium fertilizer wisely is essential for hot pepper cultivation. By selecting the right type, applying scientifically, and considering soil and timing factors, farmers can significantly improve yield and quality. Prioritize balanced nutrition and sustainable practices to maximize results.
