Attempt This Question
Not attemptedCorrect Answer: (c) 1 and 3 only
Drip irrigation supplies water only at the plant root zone; the drier inter-row area suppresses weed growth (statement 1) and the low-velocity, point-source application minimises surface runoff, thereby reducing soil erosion (statement 3). Drip does not inherently lower existing salt levels in soil; without leaching it can even lead to salt accumulation, so statement 2 is not a consistent advantage. Thus statements 1 and 3 only are correct. ([jcannabisresearch.biomedcentral.com](https://jcannabisresearch.biomedcentral.com/articles/10.1186/s42238-025-00302-x?utm_source=openai))
