Abstract
Field experiments were conducted to determine the effect of wheat grain quality under optimal planting date suitable for dual purpose (DP) system and to compare and find out wheat cultivars with good quality parameters after recovered from cutting at stem elongation stage. The experiments were laid out in randomized complete block design with split plot arrangement having three replications during winter 2009-2010 and 2010-2011 at New Developmental Farm (NDF), Khyber Pakhtunkhwa Agricultural University Peshawar. Six wheat cultivars (Saleem-2000, Bathoor-2007, Fakhre-Sarhad 99 (FS-99), Uqab-2000, Siran-2008 and Ghaznavi-98), three planting dates (15th October, 30th October and 14th November) and two cutting treatments (cut and no-cut) were included in the experiments. Results indicated that planting in end of October and 14th November resulted in higher grain moisture, crude protein, wet and dry gluten content. Wheat cultivar Ghaznavi-98 and Siran-2008 were higher in ash content whereas higher crude protein content was recorded in wheat cultivars Bathoor-2007, Uqab-2000 and Siran-2008. Crude fiber and wet gluten were in similar range for all cultivars except Bathoor-2007 and FS-99 however higher dry glutens were found in Uqab-2000 and Saleem-2000. Cutting treatment had not significantly reduced all quality parameters except dry gluten. It was concluded from the study that cutting of wheat 70 days after planting had no adverse effect on the quality of wheat grain except gluten content planted either on 30th October or 14th November and thus wheat can be used as a dual purpose crop for forage early in the season with reduced gluten content than only for grain. Wheat cv. Bathoor-2007, Uqab-2000 and Siran-2008 can be planted for dual purpose wheat without any penalty on grain quality. (C) 2015 Friends Science Publishers
