A field experiment was conducted during Kharif 2013 and Kharif 2014 on sandy loam soil to study the effect of vegetative barriers and improved forage species on growth and productivity of degraded grasslands under mid hill sub temperate conditions of Himachal Pradesh. Napier bajra hybrid (Pennisetum purpureum L. x P. Americanum L.) as vegetative barrier produced significantly taller plants as compared to setaria grass planted as vegetative barrier. Shoot population was significantly higher in vegetative barrier of setaria grass, whereas leaf stem ratio was significantly higher in vegetative barrier of napier bajra hybrid. Each forage species in sole stand and also in the grass + legume mixture produced taller plants, more number of shoots and higher leaf stem ratio under the influence of different vegetative barriers as compared to no vegetative barrier. Vegetative barrier of setaria grass (Setaria anceps L.) gave significantly higher green forage (301.96 q ha-1) and dry forage yield (66.22 q ha-1) during two years of study. Planting of grass legume mixture i.e. setaria + stylosanthes produced 25.42, 87.51 and 92.29 per cent higher green fodder yield over setaria, stylosanthes and existing forage species, respectively. The respective increase in dry fodder yield was 11.75, 70.55 and 118.86 per cent.
