| dc.description.abstract | The study entitled “Studies on productivity of Tectona grandis and Gmelina arborea based Silvipastoral system at Kanke, Ranchi” was conducted in Agroforestry research field situated of Birsa Agricultural University, Kanke, Ranchi during the session 2017-2018. The tree were established in the year 2009 and the species taken were Tectona grandis (Teak) and Gmelina arborea (Gamhar) and the forage crop such as Sudan grass (Sorghum sudanense) and Hybrid Napier grass (Pennisetum glaucum × Pennisetum purpureum) which were grown under Silvipastoral system with the following objectives: (i) To find out the Productivity of Tectona grandis and Gmelina arborea.(ii) To estimate the yield and biomass of Hybrid Napier and Sudan grass. The design adopted was Randomized Block Design with twelve treatments and three replications. They were: T1: Teak + Hybrid Napier, T2: Teak + Sudan, T3: Gamhar + Hybrid Napier, T4: Gamhar + Sudan, T5: Teak + Gamhar + Hybrid Napier, T6: Teak + Gamhar + Sudan, T7: Teak, T8: Gamhar, T9: Teak + Gamhar, T10: Sole Hybrid Napier, T11: Sole Sudan, T12: Control. From the present study it was observed that the growth performance of different tree species varied significantly from treatment to treatment under Silvipastoral system. In year 2017 maximum average tree height and diameter at breast height was recorded in T3 (5.73 m) and T1 (8.55 cm), followed by T4 (5.55 m) and T2 (8.00 cm) whereas the minimum was observed in T9 (4.16 m) and T9 (5.18 cm) respectively. The same trend was followed in the year 2018 for average tree height T3 (6.29 m) > T4 (6.11 m) > T9 (4.51 m) and for diameter at breast height was T1 (8.90 cm) > T2 (8.40 cm) > T9 (5.59 cm). Average total biomass of tree species in first year ranged from 7.81 kg tree -1 to 21.32 kg tree -1, whereas in the consecutive year it was ranged between 10.19 kg tree -1 to 25.57 kg tree -1 and the total biomass was found maximum in the combination of Tectona grandis with Hybrid Napier grass. Green fodder yield was significantly higher in open conditions than under tree shade at both the cuts. The maximum green fodder yield was in Sole Hybrid Napier (T10; 183.09 q ha-1) and the minimum was in Gmelina arborea and Tectona grandis with Sudan grass (T6; 90.00 q ha-1). Average total biomass of forage grass ranged from 31.31 q ha-1 to 77.36 q ha-1. The maximum total biomass was found in Sole Hybrid Napier (T10) and lowest in Tectona grandis and Gmelina arborea with Sudan grass (T6). Total biomass and total productivity potential of Silvipastoral systems was found highest with the combination of Tectona grandis with Hybrid Napier i.e. 29.14 t ha-1 and 21.0 t ha-1yr-1 respectively and the minimum total biomass was found in Sole Sudan grass (T11; 2.42 t ha-1) and total productivity was in Tectona grandis (T7; 2.09 t ha-1yr-1). Annual contribution of this category towards total litter production was 505.16 g m-2 yr-1. leaf litter in the species accounted for 95.40 per cent and wood (branches and twigs) contributed 4.49 per cent to the total litter. The highest litter-fall 156.30 g m-2 was recorded in the month of February followed by 151.72 g m-2 in January 151.72 g m-2 while the least litter fall 4.83 g m-2 was observed in the month of August. | en_US |
