Abstract:
Teak acceptance in agroforestry is also based on its high timber value; it is suitable for furniture, doors, decorative furniture, boards and any kind of construction work. Investigations of the interactions between trees and crops in traditional agroforestry studies in village Bade Urla, Block Abhanpur, District Raipur, Chhattisgarh, showed that the growth parameters of paddy decreased under the shade of Tectona grandis. Plant height found minimum at under the shade of Tectona grandis i.e., (33.64 cm, 70.59 cm, 109.40 cm) in 30 DAT, 60 DAT, 90 DAT and the control was maximum (35.14 cm, 73.39 cm and 111.60 cm) in 30 DAT, 60 DAT, 90 DAT. Number of total tillers m-2 at harvest was found maximum (146.46) at control and minimum (117.93) at under the shade of Tectona grandis. Number of effective tillers m-2 at harvest was significantly highest in control (121.85) i.e. control condition and lowest in under shade of Tectona grandis (85.08). Dry matter accumulation hill-1 at harvest was found maximum (13.54 g) at control and minimum (11.61 g) at under the shade of Tectona grandis. Panicle weight plant-1 at harvest was found maximum (21.32 g) at control and minimum (18.41 g) at under the shade of Tectona grandis. Significantly highest panicle length plant-1 at harvest was observed in control (27.74 cm/plant) and lowest in under the shade of Tectona grandis (26.56 cm/plant). Number of filled grains panicle-1 at harvest was found maximum (193.31) at control and minimum (183.39) at under the shade of Tectona grandis. Number of unfilled grains panicle-1 at harvest was recorded maximum under the shade of Tectona grandis (58.51 grains/panicle) and minimum found when the crop was grown under control (50.54 grains/panicle). With increasing distance from the tree base grain yield 39.11 q ha-1 & straw yield 44.54 q ha-1 significantly highest at control and lowest grain yield 35.39 q ha-1 & straw yield 41.58 q ha-1 under the shade of teak because the plant species under the agroforestry system depends on the same supply of growth and development resources, such as light, water, nutrients and thus the performance of the other components as well as the system as a whole will impact one component of the system. It is reasonable to believe that the decline may be related to the reduced availability of light together along with competition.
