Abstract:
The present study was carried out during Kharif, 2019 to study the growth of menthol mint and sugarcane as influenced by intercropping system. Results revealed that, growth of menthol mint was not significantly influenced at initial stage (45 DAP). But, in later stages significant variation in menthol mint growth because of sugarcane was observed. At 90 DAP, maximum plant height, spread, number of branches leaf area and total dry matter production (59.29 cm, 52.07 cm, 43.81, 1277.72 cm² plant^-1, 44.77 g plant^-1 respectively) were observed in sole menthol mint (T₁). Among the intercropping system with different row proportions studied, maximum plant height (50.37cm) observed in menthol mint (1 row) in sugarcane (120 cm) (T₂). While, plant spread, number of branches, leaf area and dry matter production (45.97cm, 38.53, 1095.37 cm² plant^-1, 40.95 g plant^-1 respectively) were observed in menthol mint (2 rows) in sugarcane (180 cm) (T₄). In case of sugarcane, height was not significantly affected by the intercropping system. While, maximum number of tillers per plant, leaf area, dry matter production (6.58, 14069.82 cm² plant^-1, 993.47 g plant^-1 respectively) were observed maximum in sole sugarcane (T₈) at 120 DAP. Among the intercropping system with different row proportions studied, maximum number of tillers per plant, leaf area and dry matter production (6.27, 13372.69 cm² plant^-1, 973.93 g plant^-1 respectively) at 120 DAP were observed in menthol mint (1 row) in sugarcane (120 cm) (T₂).
