The study looked at how different amounts of water and fertilizer affected the growth and quality of greenhouse-grown cucumbers. They found that giving the right amount of water and fertilizer led to taller plants, more leaves, and higher yields of good-quality cucumbers. Using a specific combination of water and fertilizer resulted in the highest yield and best quality cucumbers, while also saving water. This shows that by adjusting water and fertilizer levels, farmers can grow more cucumbers that are both high in quantity and quality.
