Show Solution

The Correct Option is A

Solution and Explanation

The average yield of a Mandarin orange crop (Citrus reticulata, Rutaceae family) cultivated in subtropical and tropical climates is determined by considering cultivation details. Mandarin trees require well-drained soil, approximately 1.5 meters deep, with adequate organic content and low salt levels. Key varieties include Nagpur santra, Khansi mandarin, and Coorg mandarin.

Commercial propagation uses methods like 'T' budding on rootstocks such as jamberi or rangpur lime. Under these agricultural conditions, the estimated average yield per tree ranges from 80 to 160 fruits, representing expected production from a healthy tree under optimal circumstances.

Therefore, from the provided options (80-160 fruits/trees, 180-200 fruits/trees, 200-280 fruits/trees, 300-600 fruits/trees), the accurate average yield for a Mandarin orange crop is 80-160 fruits/trees.
