Data was recorded on 12 divergent varieties during growth on quantity and quality parameters. Significantly different parameters of the experiment were emergence, green and total leaf number, fresh and dry leaf and stem weight, plant height, green and dry matter yield, crude protein (CP), mineral matter (MM) and nitrogen free extract (NFE). Variety F-9706 showed the highest emergence (343) per square meter. Variety No-1863 responded for the highest green (13.3) and total leaf (15.7) number per plant with 258.3 g and 20.3 g fresh and dry matter of leaves, respectively. Highest stem fresh matter (307 g) was also reported for No-1863. The dry stem mass was the highest (49.7 g) in local Tandojam. Hegari produced the tallest plant with 237.3 cm of height amongst the set of varieties. Mean leaf area was not significantly different in varieties but was measured the highest (324.5 cm2) in variety No-1863. The highest fresh matter yield of 62629 kg ha-1 was reported for variety F-9809. Significantly the highest dry matter of 17419 and 16966 kg ha-1 was reported for variety F-9809 and No-9806, respectively. Significantly the highest CP (7.97%) and MM (8.25%) were observed for JS-88. Ether extract (EE) and crude fiber (CF) of the varieties were non-significant from each other. The NFE was reported the maximum (54%) in F-9601 and F- 9603. The varieties dry matter yield by regressing with production (CP, MM, CF, EE and NFE kg ha-1) showed a strong positive relationship. Summation of production and quality traits revealed the superiority of Hegari, JS-88 and No-9806 over other varieties for general cultivation in Peshawar and of similar climatic regions as a source of good forage crop.
