A nutrient called potash is used in small quantities in the fields. It has been found from various researches that most of the crops absorb the same or more amount of nitrogen from the soil. potassium Nutrients called. It is advised to the farmers that when the soil is not able to provide the required amount of potassium for high production, then the farmer should. He should supply potassium in the soil through fertilizers to get potentially high yield. ,
Ashish Rai, Soil Specialist of Krishi Vigyan Kendra Parsauni East Champaran said that research shows that about 70-75 percent of absorbed potassium is found in leaves and straw of plants and remaining part in grains, fruits, kernels etc. Spraying of potash in paddy makes the grain strong and quality.
potassium in plants
It is clear that without potassium, no plant can grow and no crop can complete its life cycle. Potash normally activates more than 60 beneficial enzymes and is directly or indirectly involved in plant growth. Most of the absorbed potassium in plants remains in the form of free cations (K+).
main functions of potassium
- Potassium stimulates photosynthesis in plants to produce photosynthesis products or plant food.
- It encourages the transport of photosynthesis products to seeds, roots, fruits, tubers.
- Potassium plays a major role in the formation and transfer of sugars in plants, so it is of great importance in the production of cane and tuber crops.
- Potassium increases protein production in plants and improves nitrogen efficiency.
- Potassium makes an important contribution to the crops in facing harmful insects-pests, attack of diseases, drought and fog etc.
- Its abundance in plants does not allow the plant to fall.
- Potassium enhances water absorption by the roots of plants.
- By improving the quality of potassium crops, for those crops in which quality is important, such as tobacco,
- Fruit and fibrous crops preserve them.
- Potassium is essential for enhancing the ability of biological-nitrogen-fixation through beneficial bacteria.
Methods of Potash Fertilizer Application:
- Apply potassium fertilizer in a place where plant roots can absorb it. If there is no proper irrigation system, do not apply it on dry soil- surface where roots are not likely to develop. Conversely, fertilizer applied to the surface after rain or irrigation can reach the bottom with water and contribute to the growth of plants.
- Do not apply potash fertilizer directly to leaves, seeds, or roots, otherwise leaves may scorch. This fertilizer should be used by mixing it with the soil, so that the concentration is reduced.
- Spraying of potash fertilizer at the soil-surface during land preparation is extremely effective, as it allows the potash to reach a depth where the roots are spread and it can be easily absorbed.
- Fertilizer can be applied in strips over rows, in rows with seed, under and next to seeds, or in adjacent strips several weeks or months after the crop has grown.
- According to the crop, potassium can be given to potassium by using fertilizer through drip irrigation with irrigation-water.
