Abstract

An experiment of Melia composita and Emblica officinalis in combination with medicinal plants i.e. Rauvolfia serpentina and Withania somnifera was conducted in degraded lands at Naukragrant, Haridwar (Uttarakhand) and Handesra, Mohali (Punjab). The geometry of M. composita and E.officinalis in RBD at 6m x 4m with R. serpentina and W. somnifera as intercrop spacing (60x60cm) tree to crop line along with seasonal agriculture crops like Masoor and Groundnut was kept.

The growth performance of trees and soil status were observed. Initially, soil was found slightly alkaline with pH values (8.20 and 8.18) at sites Naukragrant and Handesra respectively. The average soil pH was found neutral (7.71) at site Naukragrant and slightly alkaline (7.82) value showed at site Handesra after four years of plantation. The Organic Carbon, available nutrients (Nitrogen and Phosphorus) values indicates increases at both sites and highest values found at site Naukragrant as compared to site Handesra.

Initially growth of E. officinalis performed better in respect of height at site Handesra and similarly M. composita performed better height at site Naukragrant respectively. It is also observed that E. officinalis (3.06 mt. and 27.44cm) with agriculture crops at site Naukragrant (Haridwar) and M. composita (9.38 mt. and 41.78cm) without crops at site Handesra (Mohali) performed better in respect of maximum height and girth in degraded land after 3 years plantation respectively.

The fresh yield of R. serpentina (135.30 q/ha at 90% survival) under Aonla and W. somnifera (41.57 q/ha at 50% survival) under Melia also performed maximum at site Handesra (Punjab). Similarly Masoor (8.0 q/ha) and Groundnut (13.75 q/ha) performed well under Aonla at site Naukragrant (Haridwar). M. composita and E. officinalis based agrisilvi- medicinal agroforestry have proved to be the most successful as it thrives best in adverse agro-climatic conditions as well as degraded lands.
