Persistency and productivity of perennial grass species in rangeland of cool sub-tropical and sub-temperate Himalayan region.

摘要

Improved varieties of perennial grass species, namely, Setaria (Setaria anceps) vars. PSS-1 and S-92; Guinea grass (Panicum maximum) var. HGP₂; Broad leaf Paspalum (Paspalum wetsteinii) var. PS-I; Napier-bajra hybrid var. NB-37; Kikuyu grass cv common (Pennisetum clandestinum); Rhodes grass (Chloris gayana) var. Callide, Pangola grass (Digitaria decumbens) cv local alongwith natural vegetation as a check were studied for persistency and productivity for five years i.e., 1999-2003 under natural rangelands in the cool sub-tropical and sub-temperate Himalayan region. On the basis of green fodder yield, dry matter yield, quality parameters and persistency, Setaria var. PSS-1 and S-92, and Broad leaf Paspalum var. PS-I were found superior for introduction in the rangelands of cool sub-tropical and sub-temperate Himalayan region.
