Abstract
The present study was conducted in four villages of district Tehri Garhwal, Uttarakhand, India in two altitudinal range (1000-1400masl and 1400-1800masl) and two aspects (Northern and Southern).For the estimation of production potential of Indian Barnyard millet(Echinochloa frumentacea (L.)Link) under Wild Himalayan Cherry (Prunus cerasoides D. Don), various growth and yield parameters were studied along with different distances (0-1 m, 1-2m, 2-3 m, 3-4 m and control) from tree base during Kharif season. The outcome of the study revealed that the production potential of Barnyard millet under Prunus cerasoides was reduced as compare to control. In case of elevation, lower elevation and northern aspect show maximum production potential as compare to upper elevation and southern aspect. In all the study sites, grain yield of Barnyard millet ranged between 235.97-849.97 kg/ha and straw yield ranged between 1285.80-3240.58 kg/ha. Overall results indicated a gradual increase in growth and yield performance of barnyard millet with increasing distance from tree base of Wild Himalayan Cherry. Enumeration of various trees of Wild Himalayan Cherry for Growing Stock, Volume and Carbon stock was done by measuring height and diameter individually for all the trees. Result revealed that the value of GSVD (Growing stock volume density), AGBD (Above ground biomass density), BGBD (Below ground biomass density) ranged between 18.91-29.12 M3/ha, 22.74-34.94 Mg/ha and 7.64-11.64 Mg/ha respectively. TBD (Total biomass density) and TCD (Total carbon density) in all study sites was between 30.25- 46.59 Mg/ha and 15.10- 23.29 Mg/ha respectively. Wild Himalayan Cherry was contributing 10.04 Mg/ha and 4.99 Mg/ha towards biomass and carbon stock respectively which accounts for 6.5% of total biomass and total carbon stock in study sites. Lower elevation was storing more amount of carbon (20.95 Mg/ha) in the form of tree biomass as compare to upper elevation (17.39 Mg/ha) in study sites. Soil bulk density and soil moisture in study sites varied between 1.18-1.31 g/cm3 and 27.84-36.73% respectively. Outcome from the soil bulk density and soil moisture revealed increasing trend with soil depth in all sites whereas, N, P, K, soil organic matter and soil organic carbon decreased with increasing soil depth. N, P and K in study sites ranged between 215.04-236.49 kg/ha, 44.20-55.71 kg/ha and 167.71-174.65 kg/ha respectively. Soil organic matter and organic carbon in study sites varied between 2.53-3.57 % and 1.38-1.42 % respectively.
