The performance of Gramapriya, a layer variety for rural/ tribal areas, was evaluated under intensive and free-range conditions of Tripura under all India Coordinated Research Project on Rural Poultry. The fertile eggs were procured from Project Directorate on Poultry, Hyderabad and hatched in the institute hatchery. The fertility was 81.25 % and hatchability on fertile eggs set and total eggs set were 79.97% and 64.71 %, respectively. The chicks were reared under standard managemental conditions up to 8 weeks in farm. In the farm body weight was 299.2 ± 3.76, 432.6 ± 7.27 and 688.0 ±12.76 at 4,6 and 8 weeks of age. The cumulative feed consumption was 1165g up to 6 weeks of age. Then 240 birds were distributed at the rate of 12 birds (6males+ 6females) to 20 farmers. Then body was recorded at 10,12,14,16,18,20 and 40 weeks of age at farm and farmers house (Free range) simultaneously. The average body weight was 932.8 and 914.7g, 1262 and 1006g, 1445 and 168.7g, 1581and 1213g, 1744 and 1364g, 1860and 1556g and 2773 and 2614 g at farm and farmers hose during 10,12,14,16,18,20 and 40weeks of age, respectively. The age at sexual maturity was 127.0 and 193.6 days and egg production up to 40 weeks of age was 62.13 and 34.62 eggs at farm and farmers house, respectively. Though the birds reached sexual maturity at around 190 days in the farmer’s house the persistency of lay was better and farmers were willing to keep females for longer periods. Mortality was well with in the limits during brooding (2.53%), growing (0.76%) and laying periods (2.17%) period in the farm. At farmers house the mortality was mainly due to predators (30-40%). broodiness was not observed in the birds at farmers house. Farmer could sell coloured eggs @ Rs.3-5 and male birds @ Rs. 60-90 per kg live weight or Rs.200-250 per bird weighing around 2.5-3.0kg due to color and medium size. Farmers earned around Rs.750 to 1500 by sale of eggs and male bird by rearing Gramapriya birds under scavenging conditions.
