Why did the wheat price in India fall down by 50 per cent between 1928 and 1934?

Due to depression

The Great Depression in 1929 had a major effect on prices, income, and production of goods in many countries. India also faced many such negative effects in the rural segments. One such effect was the decline in the wheat prices. It fell to almost 50% during 1928-1934. This, in turn, worsened the plight of the farmers. There was a large amount of unused crop and nobody to purchase it.
