**3. Nutrients minerals**

These are elements essential for plant to complete its cycle [6]. They are divided into macro and micronutrients [7].

#### **3.1. Macronutrients**

The macronutrients are composed by nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulphur (S). Large amount of these elements are required for plants to develop and meet its physiological activity. The macronutrients play a vital role in plant structure [8].

#### **3.2. Micronutrients**

These elements are responsible for the regulatory activity of the cell organelles. These nutrients are absorbed and found in lower concentrations in plant tissues and supply the nutritional exigency of the plant [9].
