High Density Planting (HDP) is a modern farming technique where a higher number of plants are accommodated in a unit area compared to traditional methods. For banana cultivation, HDP usually involves closer spacing, such as or , which significantly increases the plant population per hectare.
Step 1: Understand standard vs. high density.
Traditional banana planting usually accommodates about 1,500 to 2,500 plants per hectare. High density planting seeks to double or triple this number to maximize yield per unit area.
Step 2: Evaluate the numbers.
While the exact number can vary based on the specific spacing (e.g., triangular vs. rectangular), a common standard for "high density" in many commercial banana varieties is approximately 5,000 plants per hectare.
Step 3: Conclusion.
Option (B) represents the standard approximate value used in agricultural examinations for high density banana populations. Hence, the correct answer is (B).
Final Answer:

A short-day vegetable is one that requires a period of darkness longer than its critical photoperiod to initiate flowering. In agricultural classification, crops grown during the winter months (Rabi crops), like the Pea, are typically categorized as short-day or day-neutral plants depending on the specific cultivar.
Step 1: Analyze the options.
(A) Tomato: Generally classified as a day-neutral plant, as it flowers regardless of the length of the day.
(B) Pea: Often categorized as a short-day plant in several agricultural contexts because it thrives and flowers during the shorter days of winter.
(C) Chilli: Typically categorized as day-neutral.
(D) Radish: Generally a long-day plant, meaning it requires more than 12 hours of light to flower.
Step 2: Conclusion.
The Pea is the most suitable choice among the options for a vegetable that prefers or requires shorter daylight durations for its reproductive cycle. Hence, the correct answer is (B).
