For indeterminate and determinate hybrid tomato cultivars grown using raised bed nursery management or plug-tray seedling production under protected conditions, the recommended seed rate is $100 - 125\text{ g/ha}$ (or $100 - 150\text{ g/ha}$).
In comparison, standard open-pollinated (OP) varieties require a seed rate of $350 - 400\text{ g/ha}$ due to lower seed vigor and larger seedling requirements.
Correct Option: Option 3 (100-125).

Which of the following pigment is responsible for the pink colouration in guava pulp?
Pink Pulp Pigmentation in Guava (Psidium guajava):
Pink- and red-fleshed guava varieties (such as Lalit, Arka Kiran, Taiwan Pink, and Ruby) owe their rich pinkish-red internal pulp colouration to the carotenoid pigment Lycopene ($\gt 4 - 7\text{ mg} / 100\text{ g}$).
In contrast, anthocyanins impart red coloration in apples and strawberries, while xanthophylls impart yellow hues.
Correct Option: Option 4 (Lycopene).

Cause: Occurs under conditions of high ambient temperature, low relative humidity, and dry wind when transpiration rate exceeds root water uptake, leading to localized water deficit and cellular collapse of the internal spongy mesophyll tissue, producing chlorotic translucent spots that turn necrotic.
Correct Option: Option 3 (Grapefruit).

Litchi fruit reaches optimum harvest maturity when total soluble solids : titratable acidity ratio reaches
Harvest Maturity Index of Litchi (Litchi chinensis):
Litchi is a non-climacteric fruit that must reach peak physiological ripeness on the tree before harvesting.
The standard chemical maturity index is when the TSS : Titratable Acidity ratio reaches $\ge 40$ (TSS attains $18 - 20^\circ\text{Brix}$ while titratable acidity declines to $0.4 - 0.5\%$, yielding $\frac{20}{0.5} = 40$).
Correct Option: Option 4 (40).
