Description The field experiment was conducted in Alfisols to develop a package of agronomic management practices for large-scale nucleus seed production of a cytoplasmic-nuclear male-sterile (CMS) line ‘ICPA 2043’. The treatments included two planting ratios (4:1 and 3:1) of male sterile (MS):male fertile (MF) lines; two row-to-row distance (75 cm and 150 cm); two plantto-plant spacings (30 cm and 50 cm); and two irrigation frequencies (14 and 18 day intervals). The phenological attributes of ‘ICPA 2043’ were significantly influenced by the direct and interactive effects of row ratio, irrigation and plant spacing. Individual plants at wider spacing showed significant positive effect on various agronomic traits such as stem diameter, number of branches, weight of dry biomass, number of pods and yield/plant over closer spacing. These attributes however, did not translate into increased seed yield due to plant population. The study showed that the optimum spacing and irrigation for producing maximum seed yield of ‘ICPA 2043’ was 75 cm x 30 cm in 3:1 row ratio with irrigation at every 18 days(fromflowerinitiation topoddevelopment) which produced seed yield at 2013 kg/ha while in 4:1, spacing of 75 cm x 30 cm with irrigation at every 14 days produced the highest seed yield of 1693 kg/ha.
