Why, and how to make it work

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 470 mm of water here in its growing months. Rain gives about 90 mm it can use in a normal year, and 40 mm in a dry year.

Temperature

Grows best at 16–25 °C on average, and survives 7–32 °C.

Here, in its growing months (day / night):

  • Jul 34 °C / 26 °C (outside its best range)
  • Aug 35 °C / 26 °C (outside its best range)
  • Sep 35 °C / 25 °C (outside its best range)
  • Oct 34 °C / 25 °C (outside its best range)

Soil

Soil for Rajmash (Kidney Bean): 8 out of 10 (good).

  • The pH here suits it.
  • Low nitrogen matters less: it makes its own.
  • Many fields here are short of phosphorus, which it needs a lot.
  • Many fields here are short of sulphur, which it needs a lot.
  • Most fields here are short of organic carbon.

Likes pH 5.5–7.5.

  • Short of sulphur Your soil is likely short of sulphur.

    Use single super phosphate instead of DAP, or add about 100 kg of gypsum per acre before sowing.

    Ask your Krishi Vigyan Kendra what to add for this crop.

  • Short of boron Your soil is likely short of boron.

    Mix 4 kg of borax per acre into the soil before sowing.
