Correct Answer: 1, 3 and 4 only. Precise management of irrigation quantity along with the rate and timing of nutrient application are of critical importance to obtain desired results in terms of productivity and nutrient use efficiency (NUE). • It helps control of your irrigation water's alkalinity (mostly bicarbonates and carbonates), as well as the pH of your growing media. Statements 1 is correct. • The fertigation allows application of right amounts of plant nutrients uniformly to the wetted root volume zone where most of the active roots are concentrated Statements 2 is correct. • This helps enhance nutrient use efficiency. It has been found to improve the productivity and quality of crop produce along with improved resource use efficiency. Statements 3 is correct. • Fertigation is considered eco- friendly and has no relation with controlling leaching of nutrients. Statements 4 is NOT correct. Hence the answer is Option A.
