Impact of different silvipastoral systems on understorey vegetation and soil properties

Abstract

The present investigation was carried out in seven different silvipastoral systems . T -TvizCedrus deodara, - 12Robinia pseudoacacia, - Cupressus torulosa, - Prunus armeniaca, - Ailanthus altissimaTTT, T - mixed 3456plantations and T - grassland (control) of Sindh range, Ganderbal Forest Division, Kashmir Province. It aimed 7to assess floristic composition of different plantations and their impact on understorey vegetation and soil nutrients. The results revealed that 12 shrub and 43 herb species were found in all these systems. Cyanodon dactylon Ailanthus altissima Cupressus torulosa was the dominating species under grassland (control), and plantations. was dominating under plantations.was Oxalis acetosella Cedrus deodara Lolium perenne dominating species under mixed stand, and plantations. Maximum Robinia pseudoacacia Prunus armeniaca available nitrogen was recorded in T - plantation (363.76 kg ha ), whereas the highest 2Robinia pseudoacacia-1values for phosphorus and potassium (23.44 kg ha and 312 kg ha respectively) were recorded in T --1-15Ailanthus altissima plantation. Maximum soil organic carbon and electrical conductivity (2.14% and 0.51 dSm , -1respectively) was recorded in T -plantation. pH in different plantation types followed the 5 Ailanthus altissima trend of T >T T T T >T T plantations.
