What the research guides add
Rice bean is a short-day legume of the Himalayan foothills, and Feedipedia lists the conditions it tolerates.
- A short-lived perennial legume usually grown as an annual, and a fast summer-growing crop found from sea level up to 1,500 m in Assam and 2,000 m in the Himalayan hills. (Feedipedia)
- It requires a short day length to produce seeds. (Feedipedia)
- It does better where average temperatures range from 18 to 30°C and tolerates 10 to 40°C, but does not withstand frost. (Feedipedia)
- It is suited to annual rainfall of 1,000 to 1,500 mm but is fairly tolerant of drought; it can better tolerate harsh conditions than cowpea, including waterlogging and acid soils. (Feedipedia)
- It grows on a wide range of soils, including shallow, infertile or degraded soils; high soil fertility may hinder pod formation and reduce seed yield. (Feedipedia)
- In India and Nepal it is sown in February and March for a summer harvest and in July and August for a December harvest. (Feedipedia)

Frequently Asked Questions
What soil pH do rice beans need?
A pH of about 6.8–7.5. 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
Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.

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 RHS and Met Office guidance. 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.
