Abstract: The study was conducted to determine the effect of plant spacing on forage yield, yield components and quality of Mott elephantgrass at the Agronomic Research Area of Agronomy (forage production) Ayub Agricultural Research Institute Faisalabad. Mott grass was sown at 45x45 cm, 60x60 cm, 75x75 cm, 90x90 cm 105x105 cm and 120x120 cm spacing (inter row and intra row spacings). Among the different spatial arrangements the first three spacings i.e. 45x45 cm, 60x60 cm and 75x75 cm proved to be more productive, appropriate and acceptable ones. Plant spacing 45x45 cm gave significantly the maximum forage yield t ha-1, fat %, protein content and digestibility against the minimum at 120x120 cm spacing under the agro-ecological conditions of Faisalabad (Pakistan).
