A field experiment was conducted during winter (rabi) season (October-April) of 1993-95 at New Delhi, to assess the production potential, energetic and competition functions of potato (Solanum tuberosum L.) and linseed (Linum usitatissimum L.) planted in sole stand, additive and replacement series. Tuber yield of potato (28.6 Vha) and seed yield of linseed (1.76 Vha) were the highest in sole stand, while the total productivity in terms of tuber equivalent yield (31.3 Vha), energy output (97.8 x lo3MJlha), energy return (72.7 x lo3MJlha), LER (1.44) and net returns (Rs 12,800lha) were the highest when every fourth row of potato interspaced 60 cm was replaced with 3 rows of linseed interspaced 20 cm (180160 cm, 3 : 3 row ratio). Net returnlrupee investment was the highest in sole linseed (Rs 1.6) followed by 3 : 3 planting pattern (Re 0.70). The aggressivity values revealed dominance of linseed over potato, while the highest value of relative crowding coefficient (2.47 and 3.76 of potato and linseed respectively) and their product (9.30) in 3 :3 planting pattern.References
