SUMMARY

The experiment was conducted to evaluate the performance of berseem under different row proportions in intercropping system under irrigated conditions during rabi 2020-21 and 2021-22. The field experiment was laid out in factorial randomized block design (FRBD) with two factors replicated thrice. The first factor was intercrops viz., oats and barley and second factor row proportions viz., 1:1, 1:2, 1:3, 2:1, 2:2 and 2:3. The total treatment combinations were fifteen along with sole berseem, sole oats and sole barley. The results revealed that among the different intercrops, berseem recorded significantly higher yield advantage along with oats as compared to barley. Berseem + oats (1:3) intercropping systems recorded significantly higher system green forage productivity (35.10 t/ ha ), system dry forage productivity (9.52 t/ha), light interception ratio, relative yield total (0.55). This was on par with berseem + oats (1:2) (8.27 t/ha) and berseem + oats (2:3) (7.19 t/ha).

Key words: Barley, berseem, intercropping systems, oats and row proportions
