A Banana Consignment that Lost Value Between Field and Market
A 2 ha Grand Naine banana plantation in Raver taluka, Jalgaon, shoots bunches over about eight weeks. The grower harvested 12 t in a single lot 70 days after flower opening, when fingers were still angular and only about three-quarters full. Bunches were de-handed in the field and washed in the same tank all morning before packing into 20 kg CFB boxes with no ventilation, no liner and no cushioning. The truck to Delhi, about 1,400 km and 34 hours, ran at ambient 34 C. On arrival, 22% of fingers were bruised, split or rotting at the crown, ripening was uneven, and the lot fetched Rs 9/kg against the Rs 16/kg being paid for properly handled fruit. Grade-C fruit, roughly 3 t a week for five months, is currently dumped at Rs 4/kg. The grower now wants to invest Rs 12 lakh in a banana chips line and asks whether that is the right first move.
1. Rank the handling faults in order of economic damage and give the corrected protocol from field to ripening.

Ranking of faults by money lost
- Harvest at 70 days with angular, three-quarter fingers. Immature fruit cannot develop proper sugar, ripens unevenly and is more prone to mechanical damage. This alone explains much of the Rs 7/kg price gap.
- Ambient transport at 34 C in 20 kg unventilated boxes. Respiration heat cannot escape, the fruit softens, bruises and the crown becomes an anaerobic rot site. Over 34 hours this is the largest cause of the 22% loss.
- Reusing the de-latexing water all morning. Latex and soil build up a heavy inoculum load; crowns are infected before packing.
- No pre-cooling, no cushioning, no liner, oversized packs.
Corrected protocol
- Harvest at 80-85% maturity, judged by finger fill and a colour chart, roughly 900-1,100 degree-days after shooting; harvest in the cool early morning.
- De-hand on a clean mat, dip in running clean water with 2 g/L alum to remove latex, then treat crowns with carbendazim 0.1% plus a suitable sticker for crown rot.
- Pack 13 kg in ventilated CFB boxes with a perforated polyliner and cushioning; add a potassium permanganate ethylene absorbent sachet.
- Pre-cool to 13-15 C within 4-6 hours and move the truck at 13-15 C, not ambient.
- Ripen with ethylene at 100-150 ppm for 24 hours at 18-20 C and 90-95% RH. Calcium carbide is illegal and detectable, so it is not an option.
2. Evaluate the Rs 12 lakh chips line with the figures given - recovery, seasonality, margin and payback - and decide whether it should be the first investment.

Working the numbers
- Raw material: 3 t a week for 5 months, about 20 weeks, so roughly 60 t of grade-C fruit a year.
- At 20% recovery, 60 t gives about 12 t of chips.
- Revenue at Rs 250/kg = Rs 30 lakh.
- Costs: raw material valued at its current alternative use of Rs 4/kg = Rs 2.4 lakh; processing at Rs 80/kg of chips = Rs 9.6 lakh; packaging at Rs 20/kg = Rs 2.4 lakh; depreciation on Rs 12 lakh over 10 years = Rs 1.2 lakh. Total about Rs 15.6 lakh.
- Margin: roughly Rs 14.4 lakh a year, with a payback of under one year on paper.
But the paper case has three weak points
- The plant runs only 20 weeks a year; labour must be re-trained each season and idle capital is real.
- Grade-C supply depends on the main crop being harvested and handled at all - if the handling problem persists, fruit quality degrades further and even chips-grade material shrinks.
- FSSAI licensing, a stable buyer and working capital for 60 days of stock are not in the Rs 12 lakh.
Decision: fix the handling protocol first. It costs very little, and at the observed figures it protects roughly Rs 7/kg on 12 t per lot (about Rs 84,000) plus 22% of the fruit - far more than the chips line returns per rupee invested. Then start the chips line as a parallel activity, initially on a smaller scale or as a toll-processing arrangement, once the main crop is reliably reaching market at Rs 16/kg.
3. The grower says cold-chain transport will cost more than the loss he is suffering. How would you test that claim with him?

Put both options on one sheet, per truck load
- Current practice: 12 t at Rs 9/kg = Rs 1.08 lakh realised; loss relative to the Rs 16/kg benchmark is Rs 84,000, plus the 2.6 t of unsaleable fruit (about Rs 24,000 at the reduced price) - roughly Rs 1.08 lakh of value lost per load.
- Improved practice: a ventilated 13 kg pack, pre-cooling and a reefer or ventilated truck. If refrigerated transport to Delhi costs, say, Rs 6-8/kg more than ambient, that is Rs 72,000-96,000 on 12 t. Realisation at Rs 16/kg on 12 t is Rs 1.92 lakh.
- Net comparison per load: about Rs 1.92 lakh minus Rs 0.90 lakh extra freight = Rs 1.02 lakh, against Rs 1.08 lakh today - close to break-even on freight alone. The gain becomes clear once the 22% loss and the repeat-order value of consistent quality are counted.
Practical way to test it
- Send one trial consignment of 2-3 t in ventilated 13 kg packs with pre-cooling and one ambient control, both to the same buyer, and record arrival loss, price and buyer feedback.
- Compare a ventilated truck against a reefer on one trip; many growers find ventilated night transport over 34 hours recovers most of the benefit at a fraction of reefer cost.
- Use the trial data to approach the buyer for a committed price for graded fruit, which turns a cost argument into a price argument. If the buyer will not pay for quality, the investment case fails and the chips line becomes the better use of the Rs 12 lakh.
