Which nutrient deficiency could result in stunted growth and poor fruit development?

Potassium plays a crucial role in plant growth and development, particularly in the processes of photosynthesis, protein synthesis, and water regulation. A deficiency in potassium can lead to stunted growth because it impairs the plant's ability to produce energy and manage cellular processes effectively. Additionally, potassium is vital for fruit development as it affects the size, quality, and overall yield of the fruit.

In plants, potassium helps in the movement of water, nutrients, and carbohydrates within cells, influencing the growth of roots and the overall robustness of the plant. When potassium levels are low, you may observe symptoms such as yellowing of the leaf edges, poor root development, and ultimately, less desirable fruit characteristics like small size or poor flavor. Therefore, potassium deficiency is directly linked to both stunted growth and poor fruit development, making it a significant nutrient for horticultural practices.
