Nagpur orange season: when to harvest ambia and mrig fruit
Harvest timing comes from three things: fruit maturity, the market's prices and arrivals, and the next days' weather. Maturity means colour, size, juice and the sugar-to-acid balance; rain stops harvest and spoils fruit. Maturity can be tested in the orchard; a test is given here, not a number.
Last checked (AI-assisted): 15 Oct 2026. Checked on 15 Oct 2026 against published ICAR, state agricultural university and FAO guidance with AI assistance. Not yet reviewed by an agronomist or tested with farmers. No spray, pesticide, fertiliser or irrigation amount is given here; for those, test your soil and ask your KVK or an agronomist.
Maturity signs
Colour: from green to orange-yellow. Ambia fruit ripens in the warm air of October and November, so it can be mature while the rind is still greenish. Mrig fruit ripens in the cool season and colours well.
Rind: gives slightly under thumb pressure, no longer hard; the fruit parts easily when lifted. Juice: cut fruit is juicy with balanced sweetness and acidity. The CCRI sugar-to-acid ratio (TSS/acid) can be measured at the KVK.
Fruit on one tree does not mature together; harvest in two or three rounds.
The market
Prices fall when arrivals peak. Check your market's past arrivals and prices on Agmarknet and, if you can, shift the harvest a little away from the crowded weeks. No price figure is given here.
The weather
Rain in harvest week wets fruit, marks it and shortens storage. Decide the harvest only after a 5-day forecast. The satellite message carries the weather; if the fruit is ready and rain is coming, harvesting earlier beats waiting.
How to harvest
In the morning after the dew dries, with clippers, leaving a short stalk. Do not pull fruit off (rind damage). Keep wet or damaged fruit separate. Shade and clean crates, never heaps on the ground.
What the satellite shows
The satellite cannot tell whether fruit is mature. It shows orchard greenness and the weather. A small drop in greenness after harvest is normal; it is not a warning.
What to check in your field or orchard this week
- Pick and cut 5 fruit from the outside of the canopy: how are juice and the sugar-to-acid balance?
- The 5-day forecast: any rain?
- Did you check today's arrivals and prices at your market?
A Watch message says only what changed and what to check. It never names a product, a fertiliser or an irrigation amount.
Questions
Does colour mean the fruit is mature?
Not always. Colour depends on cool nights. The juice and sugar-to-acid test is more reliable; have it measured at the KVK.
Should I hold fruit on the tree waiting for better prices?
A few days is fine, but over-mature fruit drops. Fruit left late on the tree delays the stress for the next bahar; it is better to finish ambia harvest by the first week of December. Decide by the weather and the tree's condition.
Does the satellite give a harvest date?
No. It shows only the weather and greenness. Harvest is decided by the orchard test and the market.
