The experiment was conducted at Research Farm, Department of Agronomy, CCS Haryana
Agricultural University, Hisar, during the Rabi season of 2021-22 and 2022-23. It consisted of
11 treatments. Sole barley, Sole field pea, Sole linseed, barley + field pea (3:3), barley + field
pea (4:4), barley + field pea (5:5), barley + field pea (6:6), barley + linseed (3:3), barley +
linseed (4:4), barley + linseed (5:5) and barley + linseed (6:6). The experiment was laid out in
randomized block design with three replications. All the yield attributes were recorded
maximum under sole cropping of different crops when compared with their respective
intercropping systems in various row ratios. Intercropping of barley with field pea (6:6) was
found most economical as compared to barley+linseed and sole cropping of barley, field pea
or linseed. The maximum barley equivalent yield of 71.37 and 66.09 q ha -1 was recorded in
barley+fieldpea intercropping having 6:6 or 5:5 rows, respectively. Barley crop produced
significantly highest number of tillers/m 2 (122.2) and test weight was 47.4g when grown as a
sole crop followed by barley + field pea (6:6). Barley with field pea (6:6) fetched maximum
net returns and B:C of 87111 Rs./ha and 3.39, respectively. Intercropping experiments face
challenges related to complex management because it requires careful planning besides
considering the crop compatibility and resource allocation.
