ANS:B - Ammonium sulphate The most suitable fertilizer for paddy cultivation is ammonium sulfate. Paddy, or rice, is a crop that benefits from nitrogen and sulfur fertilization. Ammonium sulfate provides both nitrogen and sulfur, making it an ideal fertilizer for paddy fields. The ammonium form of nitrogen in ammonium sulfate is readily available to paddy plants, promoting vegetative growth and enhancing grain yield. Additionally, sulfur is an essential nutrient for rice plants, particularly in areas with sulfur-deficient soils, as it plays a crucial role in protein synthesis and overall plant health. So, the correct option is: Ammonium sulfate Ammonium sulfate (NH4)2SO4 is an inorganic salt that is commonly used as a nitrogen and sulfur fertilizer in agriculture. It is a white, crystalline solid that is highly soluble in water. Here are some key points about ammonium sulfate:
