Pigeon pea, known across South Asia and Africa as toor dal, is a major Indian and African crop and genuinely drought tolerant, per the crop database's own description. Unlike most legumes on this site, it's naturally a short-lived perennial shrub in frost-free climates, though it's grown here with the same annual-style sowing and harvest data as the site's other dried pulses.
Water need
Genuinely drought tolerant per the crop database -- its deep root system, typical of a shrubby perennial, helps it ride out dry spells.
Calories at a glance
3,430 kcal/kg dried -- a genuine calorie staple, in the same league as the site's other dried pulses (scale is log-based across all 55 core crops in the calculator).
Temperature Range by Month
Month on the bottom, temperature up the side. The pale green background is what the plant can survive at all -- fatal above or below it, labelled directly on the chart where that applies to your zone. The coral band is its ideal range, and only fades in during the months this zone would actually have the crop in the ground -- reusing the exact same sowing/harvesting data as the calendar further down the page. The blue line is real monthly climate data (not a modelled estimate) for a representative rural/agricultural location in this zone -- a small farming town or agricultural research station rather than a major city, to avoid the warmer bias city weather stations have. For the actual verdict on how well this crop does in your zone, see the badge at the top of the page -- that's based on the site's own researched yield figures, not this chart.
Quick Start: Sowing to Drying
- Sow direct once the soil is warm. Sow seed direct once the soil has genuinely warmed -- pigeon pea is a warm-climate crop and needs sustained heat to establish well.
- Water while establishing, then ease off. Water while young plants root in; pigeon pea's real drought tolerance takes over once established, needing little further irrigation.
- Let plants develop as a shrub. Give plants room to grow -- pigeon pea is genuinely shrubby by nature, and in frost-free zones can be left to crop again the following year rather than pulled as a true annual.
- Leave pods on the plant to dry fully. For dried storage, leave pods on the plant until they've dried and the beans inside rattle, rather than picking them young.
- Shell and finish drying indoors. Shell the dried pods and spread the beans out somewhere warm and airy for a final week of drying before storing in an airtight container.
Sowing & Harvesting Calendar
Pick your zone under "Temperature Range by Month" above and this updates too. Maritime, Boreal and Alpine show no window at all, since this site's own yield data marks pigeon pea as not viable in those zones.
Calories & Yield
Pigeon pea is a genuine calorie staple when dried at about 3,430 kcal per kg -- Tropical gives the best yield here, and it's not viable at all in Maritime, Boreal or Alpine zones.
| Climate Zone | Yield per plant | Calories per plant | Viability |
|---|---|---|---|
| Tropical / Humid | 3.0 kg | 10290 kcal | Viable -- best yield |
| Subtropical | 2.5 kg | 8575 kcal | Viable |
| Mediterranean | 2.0 kg | 6860 kcal | Viable |
| Temperate Maritime | -- | -- | Not viable |
| Temperate Continental | 0.72 kg | 2469.6 kcal | Challenging (60% yield) |
| Cool / Boreal | -- | -- | Not viable |
| Arid / Semi-Arid | 2.0 kg | 6860 kcal | Viable |
| Highland / Alpine | -- | -- | Not viable |
Figures per plant sown, dried weight, from the site's own crop database. Continental already reflects the 60% penalty applied to challenging zones.
A note on varieties: pigeon pea is mostly grown as regional landrace populations rather than widely marketed named cultivars available to home growers -- real, verifiable named-variety diversity at this scale is genuinely thin.
Seed Saving -- Quick Guide
Pigeon pea looks like a typical self-pollinating legume but isn't quite as reliable as beans or peas -- its flowers are visited by insects often enough that real crossing between varieties can happen.
SERVINGS, NOT DAILY CALORIES This works out plate-sized servings of pigeon pea from your seed during its fresh harvest window only, not your group's full daily calorie needs. For that, use the main calculator.
Estimated for your selected zone above, using this site's own germination, loss and yield figures for pigeon pea -- a helping is roughly what you'd put on a plate as part of a meal with other veg. Treat it as a planning estimate, not a promise.
Storage & Preservation
Pigeon pea is grown here specifically for dried storage -- pods are left on the plant until fully dry, then shelled and given a final week of airing indoors before going into an airtight container.
Stored this way in a cool, dry place, dried pigeon peas keep for a genuinely long time -- years rather than months, the same storage league as this site's other dried pulses.
Growing Pigeon Pea Without Bought Inputs
Pigeon pea's genuine drought tolerance and deep, shrub-like root system are themselves an input-free advantage -- it keeps producing through dry spells with little supplemental watering once established.
Pod borer caterpillars are the main pest to watch for -- checking pods regularly and hand-picking affected ones usually keeps light infestations in check without spraying.
Pigeon pea fixes its own nitrogen via bacteria in root nodules, genuinely improving the soil for whatever's grown there next -- and where frost never touches it, its real perennial nature means it can keep doing so for several seasons from the same planting.
Frequently Asked Questions
Is pigeon pea really a perennial, not an annual?
In warm climates, genuinely yes -- the crop database itself notes it's perennial in tropics, and Cajanus cajan is a short-lived perennial shrub by nature, often cropping for two to five years where frost never touches it. This site still models its sowing and harvest data annual-style, which fits how most gardeners outside true tropical zones actually grow it.
Why isn't pigeon pea viable in Maritime zones on this site?
Pigeon pea is a genuine warm-climate crop that needs sustained heat to set pods, and a cool, damp Maritime growing season simply doesn't give it that -- the crop database's own zone data marks it not viable there.
Is pigeon pea a major world crop?
Yes -- the crop database calls it a major Indian and African crop outright, and it's genuinely one of the most important dried pulses in South Asian and African cuisine, known there as toor dal or arhar dal.
