Abstract
The present investigation conducted in 10 villages of Tehri Garhwal District lies between 1400 to 2000m altitudes. Agrobiodiversity was studied by socio-economic survey, which was done with the help of a common questionnaire, semi structured inter-views with head or the old person of the family and field observations. In order to ensure the correct answers to the questionnaire, 25 households visited in each village. The productivity of tree in agrisilviculture model was estimated by measuring the height and girth of all individual trees and the crop productivity includes grain productivity, straw productivity, and biological yield. The recorded data was analyzed statistically to find out significance of the parameters.
The Volume of trees in this system ranged from 3.02 in V3 village (Saunkoti) to 7.03 m3/ha V6 village (Khatiyar). In all the documented species, maximum volume was recorded (10.43 m3/ha) in Celtis australis and minimum was recorded (1.00 m3/ha) in Juglans regia. Above ground biomass of trees in this system varies from 2.15 to 4.06 t/ha in V3 (Saunkoti) and V6 village (Khatiyar), respectively. In all the recorded species, maximum above ground biomass was recorded (4.64 t/ha) in Celtis australis and minimum was recorded (0.49 t/ha) in Juglans regia.
Mean productivity of cereals within the villages varies from 775.20 to 1129.0 kg/ha in V6 and V1 village respectively. The mean crop residue within the villages varies from 2792.40 to 4395.40 kg/ha in V4 (Dargi) and V7 (Khatiyar) village respectively. Mean biological yield within the villages vary from 3884.40 kg/ha to 5443.40 kg/ha in V4 village (Dargi) and V7 village (Sabli talla) respectively. Mean harvest index within the villages varies from 20.84 V7 village (Sabli talla) to 29.52 V4 village (Dargi).
The green fodder consumption in rainy season vary from 610.24 kg/day/village to 3463.49 kg/day/village in V9 (Hadum talla) and V3 (Saunkoti) villages, respectively. Per village green fodder consumption in winter season varied from 341.95 kg/day/village to 1947.87 kg/day/village in V9 (Hadum talla) and V3 (Saunkoti) villages respectively. Per village dry fodder consumption in winter season vary from 121.78 kg/day/village to 1535.94 kg/day/village in V9 (Hadum talla) and V2 (Dharsal) village. Per village green fodder consumption in summer season varied from 296.03 kg/day/village to 1761.25 kg/day/village at V9 (Hadum talla) and V3 (Saunkoti) villages respectively. Per village dry fodder consumption was varied from 152.39 kg/day/village V9 (Hadum talla) to 1523.33 kg/day/village V2 (Dharsal village).
From farmers point of view the current study suggested that density of Multipurpose tree species are low in villages so, quality base MPT,s should be planted under afforestation programmes on village wasteland and agricultural land. It is inversely proportional to fodder scarcity in lean period then fodder scarcity will be decrease and farmers can be also initiated integrated agroforestry model i.e. agricultural crops +MPT,s + Medicinal plants/Ornamental plants + dairy farming/goat farming. So employment opportunity will be increased in rural areas. Financial support from different funding agencies should be provide to farmers for developing of integrated agroforestry models.
