Temperature and water requirements’ change for sunflower are assumed to be the same as that for
sesame
Temperature and water requirements’ change for chickpeas and lupine are assumed to be the same
as that for lentils
Temperature and water requirements’ change for garlic are assumed to be the same as that for onions
Temperature and water requirements’ change for medicinal crops are assumed to be the same as
that for clover
