Description Two field experiments were conducted under rainfed conditions during rabi seasons of 2004-
05 and 2005-06 and two field experiments during kharif season of 2005-06 at Regional Agricultural
Research Station, Bijapur, University of Agricultural Sciences, Dharwad on medium black soils to
assess the performance of Senna (Cassia angustifolia Vahl) in the existing cropping systems of
northern dry zone of Karnataka. In the experiment on comparative performance of senna with different
rabi crops, the sole crop of senna recorded significantly higher leaf yield (880.13 kg ha-1) and pod
yield (342.45 kg ha-1) over intercropped senna. Intercropping of chickpea + senna recorded
significantly higher senna equivalent yield (1872.86 kg ha-1), gross returns (Rs. 37, 457 ha-1), net
returns (R. 27, 098 ha-1) and B:C ratio (2.62). In another experiment on comparative performance of
senna with rabi sorghum and sunflower at different row proportions, the sole crop of senna recorded
significantly higher leaf (894.64 kg ha-1) and pod (335.41 kg ha-1) yield as compared to intercropped
senna. Intercropping of sorghum with senna in 1:3 row proportions recorded significantly higher senna
equivalent yield (1232.15 kg ha-1), gross returns (Rs. 24, 643 ha-1), net returns (Rs. 16, 108 ha-1) and
B:C ratio (1.89). The experiment on comparative performance of senna with cotton, pigeonpea and
castor at different row proportions, the sole crop of senna recorded significantly higher leaf (952.64 kg
ha-1) and pod (357.86 kg ha-1) yield as compared to intercropped senna. Intercropping of senna with
cotton in 1:1 (1671.48 kg ha-1, Rs. 33, 429 and Rs. 21, 271 ha-1) and 1:2 (1734.38 kg ha-1, Rs. 34, 687
and Rs. 22, 529 ha-1) row proportions recorded significantly higher senna equivalent yield, gross
returns and net returns, respectively. In the experiment on comparative performance of senna with
pearlmillet, groundnut and sunflower at different row proportions, the sole crop of senna recorded
significantly higher leaf (964.33 kg ha-1) and pod (358.62 kg ha-1) yield as compared to intercropped
senna. Intercropping of senna with groundnut in 1:1 (1898.85 kg ha-1, Rs.39, 976 ha-1, Rs. 28, 888 ha-
1 and 2.61) and 3:3 (1962.64 kg ha-1, Rs.39, 253 ha-1, Rs. 28, 253 ha-1 and 2.57) row proportions
recorded significantly higher senna equivalent yield, gross returns, net returns and B:C ratio,
respectively.
