Market surplus of wheat crop is depends upon the volume of production, which ultimately increases with the increases in farm size. Since family requirement, irrespective of farm size usually remains the same, large farm owners had more surpluses to offer for sale in the market in comparison to others. Higher marketable surplus of wheat crop in the farms can be achieved by raising productivity level of wheat. It is well known fact that productivity level is higher on the farms operating with higher technology and mechanization which generally is true for large farm. The total marketable surplus was estimated 77.43%, but in the case of small farms, the percentage of marketable surplus was 46.22%. The marketable surplus increased as the size of farms increases it was estimated at 62.21% in medium farms and 86.76% in large farms. Overall wastage of wheat production at different levels harvest and post harvest and post harvest storage was estimated at 6.76%. It was 8.45% in the case of small farmers, 7.33% in medium farms and 6.38% in large farms. In country like India, where about 26% of the population lives below poverty line, these food grown losses comes under a criminal wastage. There is no doubt that these losses cannot be brought at the zero level but can be significantly reduced through better management and infrastructure.
