Easiest way is to do grading at the farm level. Immediately after harvest, the farmers must go for grading which is generally based on size, color and variety. This will help them to get better rates and fair returns as per quality. Simple gradation of size viz., watermelons big, medium and small, betel leaves big and small, bananas variety wise, orange size wise, potatoes size wise, rice size, broken pearl like brownish etc. At rural places, the labour charges will be economical and gradation done at that stage makes further processing and marketing easier.
It is seen in the market that the same variety of mangoes but big in size is sold at Rs.20 per kg whereas small size is sold at Rs.15 per kg. The taste is the same. The difference is in bigger mangoes where the eatable portion is more compared to smaller ones and the seed size will be same. This gives a simple example of direct advantages of grading.
Once grading is done and exhibited in term of size, color and freshness, no more explanation is required as visual observation of the consumer is adequate.
