Abstract:

A field experiment was conducted with 'LH 84' perennial lucerne (Medicago sativa L.) at Central Research Farm, Indian Grassland and Fodder Research Institute, Jhansi, Uttar Pradesh, India, from 1993-94 to 1995-96. The experiment was laid out in 33-confounding design with all combinations of 3 irrigation schedules (irrigation water:cumulative pan evaporation ratio of 0.5, 0.75 and 1.0), 3 cutting intervals (25, 35 and 45 days) and 3 K levels (0, 49.8 and 99.6 kg K/ha) replicated twice. Significantly higher green forage (103.4 tonnes/ha), dry matter (22.1 tonnes/ha), and crude protein (3.6 tonnes/ha) yields were obtained with irrigation at 0.75 IW:CPE ratio and 107.1, 22.5 and 4.0 tonnes/ha, respectively, with 35-day cutting interval. Yields were increased significantly only up to 49.8 kg K/ha, however, beyond this level there was no significant difference. The highest water-use efficiency of 37.2, 29.4 and 30.6 kg dry matter/ha-mm was recorded from irrigation at 0.5 IW:CPE, cutting interval at 35 days and with 99.6 kg K/ha respectively.
