Assessment of Onion Seed Quality Intercropped with Beet Leaf

To investigate the efficient strategy for onion seed production in intercropping systems a field experiment was conducted at CCS HAU, Hisar in two rabi seasons (2018-19 & 2019-20). Onion was grown as the main seed crop while beet leaf an intercrop with different leaf cutting frequencies. The superior onion seed quality parameters were in sole onion treatment i.e., test weight (3.73g), germination (79.7%), vigour I (1285.2), vigour II (137.5), tetrazolium (94.0%), electric conductivity (0.20 µS/cm/50 seeds) and accelerated ageing test (48.3%). Among intercropping treatments, the highest seed quality parameters were from combination, onion + beet leaf (1 row) with 3 cuttings i.e., test weight (3.53g), germination( 75.0%), vigour I (1187.1), vigour II (122.7), tetrazolium (92.0%), electric conductivity (0.21 µS/cm/50 seeds) and accelerated ageing test (46.3%). The minimum seed quality parameters were from combination, onion + beet leaf (2 rows) 3 cuttings and left for seed crop.
