The Delayed Canal and the Sowing Window
A block agriculture officer in a rain-fed block of Kandhamal district must advise 40 marginal farming families in the first week of July. The block's average rainfall is 780 mm, of which 85 per cent falls between mid-June and September, and it usually stops abruptly around 20 September. The soils are red laterite, with low water-holding capacity and a pH near 5.3. A medium irrigation canal command covers 18 per cent of the block, but water will be released only after 20 August because the reservoir stands at 41 per cent storage on 1 July. Each rain-fed family holds about 1.2 hectares and has grain for 45 more days. Four options are on the table: (a) long-duration paddy of 145 days, transplanted in July; (b) short-duration direct-seeded paddy of 95 to 100 days; (c) ragi of 90 to 95 days; (d) pigeon pea of 160 days as a sole crop. Many farmers reject ragi, saying it is a crop of the old days and that no one will buy it.
1. For the families with no canal water, which option should be recommended, and on what reasoning? Show the comparison, not just the name of the crop.

Advise ragi, or short-duration direct-seeded paddy where the field is low-lying and retains moisture - and not transplanted long-duration paddy.
Reasoning by criteria:
- Effective moisture window. Rain-fed crops must have their most water-sensitive stage, flowering, inside roughly 15 June to 20 September, about 95 days. A 145-day paddy transplanted in July would flower around mid-October, after the rain has stopped.
- Water need against supply. Transplanted paddy needs roughly 1,200 to 1,400 mm; the block receives 780 mm. Red laterite holds little water, so a 10-day dry spell at flowering causes heavy loss. Ragi needs roughly 400 to 500 mm and tolerates a dry spell at the vegetative stage. Direct-seeded paddy avoids transplanting shock and the nursery water demand.
- Household risk. With only 45 days of grain left, the family cannot absorb a total failure, so the low-variance crop wins over the high-yield one.
The belief that ragi is 'old-fashioned' is a preference, not an agronomic constraint. Answer it with a demonstration plot, a buy-back arrangement with the block's millet procurement centre, and a small processing link - not with an instruction.
2. A seed dealer offers hybrid maize seed on credit at 2 per cent per month, with a promise to buy the grain at harvest at 'the market rate'. Should the 40 families accept? Justify.

Partly, and only with conditions.
The credit is not the main risk; the price clause is. 'Market rate' transfers the whole price risk to the farmer. If maize glutted the mandi at harvest, the family would repay a fixed debt from a low price. A failed crop would still leave the debt.
Cost check. Credit of about Rs 12,000 for five months at 2 per cent per month is Rs 1,200 - small against a moneylender's 5 per cent per month. Hybrid maize of about 110 days also fits inside the rainy window, but it needs more fertiliser and is more drought-sensitive at flowering than ragi.
Recommended conditions: (i) a buy-back price written down as a floor figure, not 'market rate'; (ii) the dealer's seed on only part of the holding, so a failure does not sink the household; (iii) low-lying fields only, where moisture is better; (iv) enrolment under crop insurance before the cut-off date; (v) the family keeps its 45 days of grain untouched as a buffer.
3. Separately, what should the block office do about the 20 August canal date, beyond choosing crops?
Read the worked answer
The canal date is an administrative decision, not a rainfall fact, so it is the part most open to change.
- Match release to the crop calendar. The office should place before the reservoir authority the actual requirement: an earlier release for short-duration paddy in the command, or a later, smaller release for a low-water crop. The command's 18 per cent of area should be planned crop by crop, not as 'paddy area'.
- Protect the tail-end. In a delayed release, head-reach farmers take more than their share. The office should publish a rotation (warabandi) schedule by outlet, with dates and hours, before the release.
- Reduce dependence. Farm ponds and field bunding under the watershed programme extend the effective season; direct seeding cuts the nursery water demand.
- Cover the residual risk. Insurance enrolment is a deadline task, not advice. A household that has already lost a crop cannot insure it later.
- Do not promise double cropping. With 41 per cent storage in July, a rabi promise would be a false assurance; the plan should state one sure crop plus a possible second.
