The researchers studied how different types of fertilizers affect the growth and yield of chilli plants. They used a variety of chilli called Jwala and tested different combinations of organic and inorganic fertilizers. The best results were seen with a mix of tank silt, farmyard manure, and inorganic fertilizer, which led to taller plants with more branches and higher yields. This combination also increased the uptake of important nutrients like nitrogen, phosphorus, and potassium, as well as micronutrients like iron and zinc. Overall, using a mix of organic and inorganic fertilizers can help chilli plants grow better and produce more fruit.
