Directions: The following items consist of two statements, Statement I and Statement II. You are to examine these two statements carefully and select the answers to these items using the code given below:Statement I: Growth of plants is smooth with a complete fertilizer.Statement II: A complete fertilizer always contains N, P, K.

The correct answer is Option 2.The growth of plants is smooth with a complete fertilizer. Hence statement I is correctNitrogen, Phosphorus, Potassium, Calcium, Magnesium, etc. are the essential elements for plant growth.Plants cannot absorb these elements directly from the air even though elements like Nitrogen is available in a large AMOUNT (some of the plants in association with N2-fixing bacteria, especially roots of legumes, can fix this atmospheric nitrogen into biologically usable forms).Some of these elements will deplete in the soil very quickly and hence plants can absorb it in the form of complete fertilizers. A complete fertilizer always CONTAINS N, P, K. Hence statement II is correct.A complete fertilizer is a fertilizer that contains the THREE main plant NUTRIENTS: Nitrogen (N), Phosphorus (P), and Potassium (K).Potassium helps plants to develop strong stems and growing fast.Nitrogen helps plants for the growth of leaf and green color.Phosphorous helps plants to form new roots, MAKE seeds, fruit, and flowers.There are six essential nutrients namely nitrogen, phosphorus, potassium, magnesium, sulfur, and calcium are essential for the growth of plants. Hence Statement II is not the correct explanation of Statement I.
