What the research guides add
Urd bean is the same crop as black gram, an Indian pulse, and Feedipedia gives the temperature and soil window it likes.
- It is generally found in lowlands but can grow up to 1,800 m above sea level provided there is neither frost nor prolonged cloudiness. (Feedipedia)
- Optimal growth conditions are average day temperatures of 25 to 35°C and annual rainfall of 600 to 1,000 mm. (Feedipedia)
- It grows better on rich black vertisols or loamy, well-drained soils with a pH of 6 to 7. It can withstand acidic soils (down to pH 4.5) if lime and gypsum are added, but is sensitive to saline and alkaline soils. (Feedipedia)
- It is often used as a dry-season intercrop in rice or wheat, as it has a beneficial effect on soil nutrient status. (Feedipedia)
- It has poor tolerance of wet tropical climates, but in high-rainfall areas it can be grown in the dry period on residual moisture. (Feedipedia)

Frequently Asked Questions
How long do urd beans take to grow?
Typically 60–140 days, depending on cultivar and growing conditions.
What soil pH do urd beans need?
A pH of about 6–7. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
Plan next season before the problems start
Short-season growing is arithmetic before it is technique: days to maturity against frost-free days decides what will finish at all. The Canada Garden Planner does that subtraction for your region before you sow.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against Canadian hardiness-zone and frost-date data, with provincial agriculture and university extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
