\textbf{Abstract}
\begin{abstract}
\normalsize{
A field experiment was conducted to study the influence of harvesting time on growth, yield and quality of three forage sorghum cultivars during 2013 at research farm, Department of Agronomy, University of Agriculture, Faisalabad. The experiment was comprised of four harvesting intervals (\mbox{25\,\%}, \mbox{50\,\%}, \mbox{75\,\%} and \mbox{100\,\%} flowering) and three cultivars (Sorghum 2011, JS-263 and JS-2002) for evaluation. Randomised complete block design (RCBD) with factorial arrangement and three replications was used in the experiment. Net plot size was \mbox{1.8\,m} $\times$ \mbox{6\,m}. The data was recorded for yield and quality relating traits viz.,higher plant height was recorded 51.3 (\mbox{100\,\%}), number of leaves per plant, leaf area per plant, stem diameter, plant density, forage yield, dry matter yield, dry matter (\%), crude protein contents (\%), crude fiber contents (\%) and ash contents (\%). The growth yield and quality parameters differed among the cultivars. As for harvesting intervals growth and yield was increased with delaying the harvest but quality was decreased. For getting higher forage yield of good quality the sorghum cultivar JS-2002 can be sown under Faisalabad conditions and it should be harvested at \mbox{50\,\%} flowering. Among sorghum cultivars maximum plant density (51 m$^{-2}$), more number of leaves (14.09), more leaf area per plant (2724.7 cm$^{2}$),  higher weight per plant (137.92 g), high forage yield (55 t ha$^{-1}$), more dry matter yield  (15.70 t ha$^{-1}$),  high crude protein content (\mbox{7.51\,\%}) and more ash content ( \mbox{8.20\,\%}) was recorded with JS-2002 cultivar. Among  harvesting interval taller plants (\mbox{241.22\,cm}), more number of leaves (15.15), higher leaf area per plant (2732.7 cm$^{2}$),  more stem diameter (\mbox{1.05\,cm})  more weight per plant (137.74 g), maximum forage yield (61.33 t ha$^{-1}$), more dry matter yield (21.37 t ha$^{-1}$), maximum dry matter (\mbox{38.44\,\%}) and more crude fiber content (\mbox{33.73\,\%}) was resulted with \mbox{100\,\%} flowering interval.}
