Quantitative information about sowing time and soil temperature on seedling emergence in chickpea (Cicer arietinum L.) is scarce. Therefore, fifteen cultivars of chickpea were evaluated CCS Haryana Agricultural University, Hisar for cumulative seedling establishment based on per cent germination and thermo tolerance index (TI) i.e; ratio of seedlings surviving to total number of seedlings emerged during rabi seasons of 2004 and 2005 under field conditions. The TI value was constantly higher in Pusa 256 cultivar in all the experiments. The TI values ranged between 0.85 to 1.00 in Experiment 1, 0.84 to 1.00 in Experiment 2, 0.88 to 1.00 in Experiment 3, 0.84 to 1.00 in Experiment 4, 0.84 to 0.94 in Experiment 5 and 0.72 to 0.94 in Experiment 6. In general, the early sown (October) cultivars recorded higher rate of seedling emergence than the cultivars late sown (November). The results suggest
that poor stand/seeding establishment of some chickpea cultivars might be due to lower initial seeding emergence rather than subsequent seedling survival and the importance of environmental conditions before emergence.
