Correct option is C
The correct answer is: (C)3 - 3.5 kg/ha
Explanation:
For small-seeded types of watermelon (Citrullus lanatus), the recommended seed rate is 3 - 3.5 kg per hectare.
Since small-seeded varieties have smaller seed size and a higher germination percentage, a slightly higher seed rate is used to achieve the desired plant population.
The seed rate is also influenced by plant spacing, soil fertility, and climate conditions.
Information Booster:
Watermelon is a warm-season crop, grown best in sandy loam soil with a pH of 6.0 to 7.5.
The ideal spacing is 2.5 - 3.0 m (row to row) × 0.6 - 1.2 m (plant to plant).
A proper seed rate ensures optimum plant population, which leads to better fruit development and higher yield.
