Study on grass yield and composition under two age group plantations of Pinus roxburghii and open grassland was conducted at Kyarighat, 23 km from Shimla on Shimla-Kalka road during the year 1979, 1980 and 1981 respectively. Abundance, frequency, density and I.V.I. (Improtance Value Index) of each grass species under three sites have been recorded. Maximum yield (5094.36 kg/ha/yr) has been recorded in open grassland followed by Pinus roxburghii plantations of the year 1971 (4067.23 kg /ha/yr) and the year 1953 (3415.50 kg /ha/yr) respectively in decreasing order.

Abstract


Study on grass yield and composition under two age group plantations of Pinus roxburghii and open grassland was conducted at Kyarighat, 23 km from Shimla on Shimla-Kalka road during the year 1979, 1980 and 1981 respectively. Abundance, frequency, density and I.V.I. (Improtance Value Index) of each grass species under three sites have been recorded. Maximum yield (5094.36 kg/ha/yr) has been recorded in open grassland followed by Pinus roxburghii plantations of the year 1971 (4067.23 kg /ha/yr) and the year 1953 (3415.50 kg /ha/yr) respectively in decreasing order.
