The response of sugarbeet variety Kaweterma to different fertility levels was ascertained in the field. The treatments included six N-P levels viz. 0-0 (control), 50-50, 75-75, 100-100, 125-125 and 150-150 N-P kg per ha. Application of N-P fertilizers in higher quantities (150-150 kg per ha) resulted 93230 per ha plant population, 62.50 cm leaves length, 37.38 leaves per plant, 2.22 kg sugarbeet weight per plant, 83.142 m.t per ha beetroot yield, 22.37% brix content and 11.34% sugar recovery. N-P application at the rate of 125-125 and 100-100 kg per ha produced 92367 and 90053 per ha plant population, 61.25 and 58.75 cm leaves length, 35.91 and 31.95 leaves per plant, 2.21 and 2.13 kg sugarbeet weight per plant, 80.588 and 79.484 m.t per ha beetroot yield, 22.34 and 22.11% brix content and 11.31 and 11.19% sugar recovery. It was observed that there was a gradual improvement in all the growth and yield components with increasing fertility levels. However, this increase was uneconomical when applied beyond 100-100 kg per ha, because differences amongst 100-100, 125-125 and 150-150 kg N-P per ha for all the parameters were statistically non-significant. Hence, 100-100 kg N-P level was considered to be an optimum level for economical production of sugarbeet under Tandojam conditions.
