National Bamboo Mission envisages bamboo plantations over more than 1.7 ha which will need more than 7 crore plants. It is not enough to rely upon seedlings alone to meet this requirement and several organizations have started experimenting propagation by vegetative methods. These experiments have not finally concluded, but trends noticed in them can be predicted to some extent. Besides new techniques and machinery have also to be evaluated. Basing on these trends of bamboo have also to the evaluated. Basing on these trends seven bamboo species which include Bambusa balcooa, B. bambos, B. nutans etc. have been identified for pan Indian large scale plantations while 8 other species which include Dendrocalamus asper, Phylostachys pubescens, Guadua angustifolia etc. can be tried for regional plantation.- Stable Variegated Mutant in Dendrocalamus Asper (schult.)

Knowledge of carbon (C) pools in soils is helpful in devising practices for efficient carbon management in intensive cropping systems. Carbon fractions of soil organic carbon are used asan indicator for land-use induced change in soil quality. The present study evaluated carbon pools under Terminalia chebula(chebulic myrobalan) based agroforestry system supplied with different nutrient sources, viz. farmyard manure, poultry manure, vermicompost, wheat straw and inorganic fertilizer (NPK @ 100:80:60). Carbon fractions, viz. very labile (C1 frac), labile (C2 frac), less labile (C3 frac) and non-labile (C4 frac), were analysed at 0–15 and 15–30 cm soil depth. The higher value of C1 frac (13.8%), C2 frac (4.8%), C3 frac (8.3%) and C4 frac(11.1%) were recorded under agroforestry as compared to open system. Among the nutrient sources, all the carbon fractions were higher under 100% integrated nutrient sources as compared to controlled treatment. Microbial biomass carbon (MBC) was recorded higher (298.31 μg g–1 ) under agroforestry system compared to the open system (290.63 μg g–1 ) at 0–15 cm. Among the different nutrient sources, higher MBC (458.66 μg g–1 ) at 0–15 cm and lower (340.59 μg g–1 ) at 15–30 cm soil depth was recorded in 100% integrated treatment.Thus, agroforestry-based land-use types and integrated nutrient management are more efficient for soil health and carbon management in Himalayan foothills.Keywords

Agroforestry has great potential for carbon (C) sequestration among different land uses of the Himalayan region, India. However, our knowledge of C sequestration in particular, agroforestry system around the world is poor. Therefore, we conducted a study to understand biomass accumulation and carbon allocation in different components of the agroforestry system. The highest stem biomass was recorded in Eucalyptus tereticornis (69.43 ± 0.90 Mg ha–1), branch biomass in Populus deltoids (5.04 ± 0.35 Mg ha–1), leaf biomass also in P. deltoids (2.21 ± 0.12 Mg ha–1), and ischolar_main biomass in Albizia procera (14.01 ± 0.44 Mg ha–1). The highest (81.01%) C allocation was recorded in the stem of Toona ciliate, branch of P. deltoids (5.73%), leaves of E. tereticornis (2.93%) and ischolar_main of Anthocephalus cadamba (16.83%). The highest CO2< mitigation (160.5 ± 2.55 Mg CO2 ha–1) and C sequestration (45.33 ± 0.60 Mg ha–1) were recorded in E. tereticornis. The highest wheat crop biomass (11.85 ± 0.23 Mg ha–1) and C stock (3.59 ± 0.05 Mg ha–1) were recorded in P. deltiodes. However, soil carbon stock was recorded in E. tereticornis (37.5 ± 3.52 Mg ha–1). Thus, trees on farmlands with crops are suitable for biomass production and C allocation in different components under changing climatic scenarios.Keywords
