Abstract
To evolve a suitable fertilizer management schedule for rice variety Cheradi, an experiment was conducted at State Seed Farm, Kottarakka, Quilon District during the second crop season of 1984-85. The treatment consisted of four graded levels of fertilizers (40: 20: 20, 50:25:25, 60:30:30 and 70:35:35 kg NPK/ha) and four times of application of nitrogen. The experiment thrice in a Factorial Randomised Block Design. Growth characters such as plant height, number of tillers/m2, LAI, CGR and dry matter production were the highest at the level of 70: 35: 35 kg NPK/ha. Interaction between levels of fertilizers and time of application of nitrogen influenced the LAI at active tillering stage. The LAI was the highest when 70 kg nitrogen was given 50% as basal, 25% each at active tillering and panicle initiation stages.
