Managing sulphur deficiency in rabi crops

摘要

Sulphur is increasingly being recognized as the fourth major plant nutrient after nitrogen, phosphorus and potassium. Sulphur deficiency in crop has been recognized as a limiting factor not only for crop growth and yield but also for poor quality cropproduce. Sixteen elements have been recognized as essential plant nutrients. These elements are categorized in to two groups namely: macro (carbon, hydrogen, oxygen, nitrogen, phosphorous, potassium, calcium, magnesium and sulphur) and micro (zinc, iron, manganese, copper, molybdenum, boron and chlorine) nutrients. Macronutrients are required in large amounts. Whereas, micronutrients are required relatively in small amounts but are equally essential. The farmers are generally taking care to supply macronutrients to crops but sometimes ignore the sulphur and micro nutrients thereby, resulting in poor yield of the crops under deficient conditions.
