Nitrogen deficiency in a bean plant reveals itself through pale leaves, especially lower down on the plant. The problem can be addressed by simply adding nitrogen, but the crop will take some time to absorb it. Because beans grow rapidly, this time lag may ultimately affect plant size.
You therefore need to respond quickly to a nitrogen deficiency. Spray urea at 5kg/ha to get some nitrogen into the leaves to speed up the process while the plant is starting to take up the applied nitrogen through the roots.
Don’t overdo things, however; if you stimulate growth too much, you might end up with too many leaves, which will usually lower the yield.
ENSURE THAT SUFFICIENT NITROGEN IS APPLIED IN THE EARLY STAGES
