Abstract

An experiment was carried out in the medicinal and aromatic plant block of Experimental Farm (Horticulture), Department of Horticulture, College of Agriculture, Assam Agricultural University, Jorhat during 2010-2011 and 2011-12. The experiment was laid out in Randomized Block Design with seven treatments viz,T0=control, T1=100% RF + FYM 5t/ha (RF: reference dose of fertilizer @ 10 : 60 : 30 kg/ha N, P2O5 and K2O, T2=75% RF + Azotobacter @20 g per plant + PSB @20 g per plant + FYM 5t/ha, T3 =50% RF+ Azotobacter @20 g per plant + PSB @20 g per plant + FYM 5t/ha,T4 =25% RF+ Azotobacter @20 g per plant + PSB @20g per plant + FYM 5t/ha, T5 =50% RF + FYM 5t/ha + Vermicompost 1t/ha, T6 =50% RF + FYM 5t/ha + Enrich compost @2t/ha (AAU made) and three replications for two years to determine the biometric and yield performance of Rauwolfia tetraphylla under different nutrient sources. The soil of the experimental plot was sandy loam having pH of 4.8, organic carbon (10.05 %), available N (243.32 kg/ha), available P2O5 (24.98 kg/ha) and available K2O (94.75 kg/ha). The maximum value of plant height (89.15 cm), leaf number (374.70), leaf area index (2.62), branches (19.09), flowers (372.54) and fruits per plant (295.09), seed and root yield (8.94kg/ha and 2809.64kg/ha) were recorded under treatment T2. The highest value of total alkaloid(1.28mg/100g dry weight), Phenol(1.69mg/100g dry weight), Tannin (0.45mg/100g dry weight) and Flavonoids (1.70mg/100g dry weight) were recorded by the treatment receiving vermicompost in combination with 50% RF dose of fertilizer and organic manures (T5).
