Marigold

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 560 mm of water here in its growing months. Rain in its months gives about 10 mm it can use in a normal year (0 mm in a dry one), and the soil holds about 0 mm from the monsoon at sowing.

Temperature

Grows best at 18–27 °C on average, and survives 11–34 °C.

Here, in its growing months (day / night):

• Oct 33 °C / 18 °C
• Nov 28 °C / 11 °C
• Dec 23 °C / 7 °C (outside its best range)

Money

Yield: about 49 quintals an acre, the typical figure across India (no figures for your state).

Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.
