dc.description.abstractThe present investigation entitled “Effect of different pruning intensities on growth and yield of different grasses under harar based silvipastoral system” was conducted at experimental farm of RHR&TS, Jachh, Kangra, of Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the year 2019. The experiment was laid out in a split plot design. The design consist of four main pruning treatments i.e. 0%, 20%, 40%, 60% and one in open condition and four sub treatments i.e. Napier grass, Guinea grass, Setaria (S-92), Setaria (PSS-1). The Napier grass (NB-37) recorded the maximum plant height and Setaria (S-92) recorded the lowest plant height under Terminalia chebula. Whereas, Setaria (S-92) has recorded the maximum number of shoots per meter square which was followed by setaria (PSS-1) and Napier grass (NB-37) has recorded the lowest number of shoots per meter square. Tree and grass species have shown significant interaction and have therefore reported significant difference in plant height, leaf-stem ratio, number of shoots /m2 and number of tillers per tussocks. Among different pruning intensities of harar the maximum grass growth was recorded in 60% pruning and the minimum was recorded under tree without pruning. Whereas, among different grasses the maximum leaf stem ratio was recorded in Napier grass (NB-37) whereas the maximum number of shoots /m2 and number of tillers per tussock were recorded in Setaria (S-92) grass. Significantly higher green fodder yield and dry fodder yield were recorded in case of Napier grass (NB-37). Setaria grass (PSS-1 and S-92) recorded the maximum crude protein yield and crude protein content among all the grasses. Among different pruning treatment 60% pruning recorded the highest yield and tree without pruning recorded the lowest yield per ha. The maximum tree height and d.b.h were recorded in 20% pruning. The maximum harar fruit yield was recorded in 40% pruning treatment. The highest value of available nitrogen, phosphorus, potassium in soil was recorded in tree without pruning treatments and the lowest value was recorded under open condition. Soil properties viz. soil pH, OC and EC were also higher in tree without pruning treatment. Among different pruning treatments the highest benefit cost ratio was recorded in 60% pruned tree planted with Napier grass.en_US
