The present study was carried out at the Instruction–cum-Research farm of Assam Agricultural University, Jorhat, summer, 2016..The experiment was laid out in factorial randomized block design replicated thrice to assess the “Integrated nutrient management and spacing in Tulsi”. The treatments consisted of two different species Ocimum sanctum (V1), Ocimum gratissimum (V2), along with two different plant densities viz., 40×40cm (S1), 50×50cm (S2) and four doses of integrated nutrient management - 6ton/ha Vermicompost (F1), 20-10-10 N-P2O5-K2O kg/ha + 3t/ha Vermicompost (F2), 40-15-15 N-P2O5-K2Okg/ha + 3t/ha Vermicompost (F3), 60-20-20 N-P2O5-K2O kg/ha + 3t/ha Vermicompost (F4), Between the two species of tulsi significant influence on various growth parameters were found. O. gratissimum (V2) was found statistically superior in regards to growth attributes in all the growth stages than that of V1. This species also recorded significantly higher in almost all the yield attributing characters than that oft Ocimum sanctum. The highest leaves yield (4.46t/ha) and oil yield (29.60kg/ha) yield were obtained in O. gratissimum and was significantly superior over that of O. sanctum. Results revealed that between the two spacing, 40×40cm (S1) showed statistically superior values in regards to almost all the growth and yield attributes. However, fresh leaves yield (3.26t/ha) as well as oil yield (21.84kg/ha) obtained in 40×40cm (S1) were significantly higher than that of 50×50cm (S2). Among the four sources of INM (F4) was found statistically superior in regards to growth and yield attributing character than that of all other nutrient treatment levels.
