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.

Which of the following methods is highly suitable for drying of hydrangea flowers ?
EXPLANATION
Techniques in dry flower making – Drying, bleaching, dyeing, embedding, pressing
Drying Methods for Hydrangea (Hydrangea macrophylla):
Hydrangea mophead blooms have large, papery, delicate petaloid sepals that easily crumple, shrink, or turn brittle if dried in air or pressed.
Water Drying Method: Freshly harvested mature hydrangea inflorescences (cut when individual florets feel slightly papery) are placed in a container with a small amount of water ($2-5\text{ cm}$).
As the water is slowly transpired and naturally evaporates over 10–14 days in a dark, dry room, the florets desiccate gradually from the base upward, retaining natural globular form, petal texture, and soft antique coloration without drooping.
Correct Option: Option 2 (Water drying).
