Which of the following stage is critical for irrigation in Rice crop?
Answer: C
The critical stage among the options is Early tillering.
Rice is sensitive to water stress at several stages: early tillering, panicle initiation, booting and flowering. Stress during tillering reduces the number of productive tillers and so the number of panicles, which is why early tillering is listed as a critical stage for irrigation.
Crown root irrigation refers to wheat's first critical irrigation, not rice. Sprouting is not an irrigation stage of the transplanted crop, and tasselling (spelt 'Tarselling' in the paper) is the critical stage of maize.
