Which effects are generated by advection in the crop fields... | Agrigyan

• Short Day Plants $\rightarrow$ (IV) Rice: Rice (Oryza sativa) initiates floral induction only when the photoperiod is shorter than its critical day length.
• Long Day Plants $\rightarrow$ (I) Wheat: Wheat (Triticum aestivum) requires photoperiods longer than its critical day length to transition from vegetative growth to heading and flowering.
• Day Neutral Plants $\rightarrow$ (II) Tomato: Tomato (Solanum lycopersicum) flowers regardless of day length, controlled primarily by physiological node number and vegetative vigor.
• Intermediate Plants $\rightarrow$ (III) Andropogon: Andropogon scoparius requires an intermediate photoperiod window (neither too long nor too short) to initiate flowering.

Correct option: (4) (A) - (IV), (B) - (), (C) - (I), (D) - (ttl)

• Advective Microclimatic Effects:
• Oasis Effect (A): Sensible heat advection from hot, dry surrounding arid landscapes into an isolated, moist irrigated field. The imported thermal energy significantly increases evapotranspiration (ET) beyond local net radiation ($LE \gt R_n$).
• Clothesline Effect (B): Occurs when warm, dry air enters the leading outer edge of an isolated crop canopy, driving intense localized ET along field borders.
• Thermoelectric Effects: The Seebeck effect and Peltier effect are physical thermoelectric circuit phenomena unrelated to microclimatic heat transfer.
• Conclusion: Statements (A) and (B) only represent advection effects in crops. (Correct answer: Option 1)
