Abstract :

BACKGROUND: Nitrogen is a crucial component of plant nutrition, and its deficiency limits productivity of crops more than any other element. To manage the sorghum crop for achievement of maximum forage production, the farmer should be concerned about nitrogen requirement and plant height. OBJECTIVES: This research was carried out to evaluate response of morphological traits, seed protein content and prussic acid concentration of Sorghum to different level of urea fertilizer and cutting height. METHODS: Current study was conducted via split plot experiment based on randomized complete blocks design with three replications along 2012 year. The main factor included three level of urea fertilizer (200, 300 and 400 kg.ha-1) and three level of cutting height (7, 12 and 14 cm) belonged to subfactor. RESULT: Result of analysis of variance revealed effect of different level of urea fertilizer, cutting height and interaction effect of treatments on all studied characteristics was significant at 5% probability level. Assessment mean comparison result of interaction effect of treatments on all measured traits indicated the maximum amount of seed yield (693 gr.m-2), panicle length (15.43 cm), stem diameter (15.90 cm), plant height (174.73 cm), prussic acid concentration (276.96 ppm) and seed protein concentration (10.90%) were noted for 400 kg.ha-1 urea and 7cm of cutting height and lowest amount of mentioned traits belonged to 200 kg.ha-1 urea and 17cm of cutting height treatment. CONCLUSION: Generally result of studied research revealed 400 kg.ha-1 urea fertilizer and 7cm cutting height had the highest amount of studied characteristics and it can be advice to farmers.
