Abstract
Leaf production, leaf fall, leaf protein and net primary productivity have been reported for 4-year-old fodder trees in the mid-western Himalaya (altitude 1350 m; rainfall 1100 mm). The species include; Grewia optiva, Robinia pseudoacacia and Celtis australis growing in the open and Quercus glauca, Q. leucotrichophora and Ilex odorata growing in the forest. G. optiva, R. pseudoacacia and C. australis showed two distinct periods of leaf flush, and their leaves were short-lived (180 to 360 days) compared with the remaining three species which retained their leaves for more than two years, and had only one flush period during March–April. The open site species showed much higher leaf production, and the leaves contained a significantly (P < 0.05) higher protein content, compared with the forest group. Net primary productivity of G. optiva, C. australis and R. pseudoacacia was significantly (P < 0.05) higher than the forest species, which may be related to their high leaf production and rapid turnover rate of the leaves. The results are useful for management of these species in agroforestry systems.
