Abstract

A field experiment on growth of tree species and yield performances of different blackgram varieties under Bijasal based agrisilviculture system was carried out. The experimental plots were laid out in randomized block design with nine treatments and four replications. The findings indicate that the maximum height increment of Bijasal (Pterocarpus marsupium) was found in T₁ :Bijasal+ Black gram (Var. Birsa Urd-1) 52.42 cm followed by T₄ :Bijasal+ Black gram (Var. Uttara) 49.97 cm, T₂ :Bijasal+ Black gram (Var. Birsa Urd-2) 46.12 cm which was at par with each other whereas the maximum collar diameter increment was found in T₁ :Bijasal+ Black gram (Var. Birsa Urd-1) 0.69 cm followed by T₄ :Bijasal+ Black gram (Var. Uttara) 0.64 cm, which was at par with each other. The maximum height of black gram was found in T₉ : Sole Black gram (Var. Uttara) 63.52 cm and minimum in T₃ : 9 Bijasal+ Black gram (Var. WBU-109) 52.75 cm. The grain yield of black gram was found significantly superior in T₆ : Sole Black gram (Var. BU-1) 13.76 q ha^-1 followed by T₉ - Sole Black gram (Var. Uttara) 12.87 q ha^-1, T₇ - Sole Black gram (Var. Birsa Urd -2) 12.10 q ha^-1 which was at par with each other and minimum in T₃ : Bijasal + Black gram (Var. WBU-109) 9.9 q ha^-1.
