The present study was conducted to analyze the production and marketing system of Khasi Mandarin in Eastern Himalayas of India. The data was collected through pre-tested schedule by personally interviewing the farmers selected through multistage sampling technique. The objectives were studied using analytical tools like semi log exponential function, marketing cost, marketing margin, price spread and marketing efficiency analysis using Acharya’s and Shepherd’s approach The results of the study revealed that the compound growth rate of area (-1.42%) and production (-0.36%) of Khasi mandarin was negative and had badly affected the Khasi mandarin cultivation in the study area. However, the positive growth rate of productivity (1.08%) was responsible for maintenance of production at a decent level. The marketing efficiency estimated by using both Acharya’s approach and Shepherd’s approach was found highest in Channel- I (Producer - Retailer – Consumer) followed by channel-II (Producer – Merchant wholesalers– Retailers – Consumers) and channel –III (Producer – Pre-harvest contractors – Wholesalers – Retailers – Consumers), respectively. The producer’s share in consumer’s rupee was also maximum in channel-I (50.43%) followed by channel-II (36.55%) and channel-III (20.38%). It was found that price spread was maximum in channel III (` 5080.00) followed by channel II (` 3820.00) and channel I (` 2537.50).
