The present study analyses the total yield gap in paddy crop in to three different gaps viz. yield gap-I, yield gap-II and total yield gap. The study based on primary as well as secondary data was carried out in three districts of plain zone namely Rajnandgoan, Mahasamund and Dhamtari districts. At the second and third stage of sampling, two blocks and two villages were selected from each district and each block, respectively to constitute a total of 6 blocks and 12 villages. Primary data were collected from a sample of 240 paddy farmers (20 from each village) through personal interview method and secondary data were collected from respective districts of K.V.K in crop year 2016-17. Most of the sample farmers were growing Rajeshwari (IGKV R -1) variety of paddy crop. Yield gap analysis shows that 13.22 per cent yield gap was estimated between potential and potential farm yield where as yield gap between potential farm yield and actual yield was estimated overall 20.00 per cent. Index of realized potential farm yield was observed 71.78 per cent on marginal farms to 89.44 per cent on large farms with an overall average of 80.00 per cent. It may be inferred from the study that the use of important variable has to be carefully extended by the paddy farmers to minimize the yield gap. Besides, the input supply of quality inputs viz. seeds, farm yard manure, irrigation and plant protection measures on different categories of farms may help to reduce the yield gap of the crop on the one hand and raise the income of the cultivators on the other.
