GhoneimAdel EbidAzza 6200726To evaluate the effect of different wheat seed categories with farmers seed for yield and yield components. An experiment was conducted at Agriculture Research Farm, NWFP Agricultural University, Peshawar, during 2003-04. The experiment was laid out in Randomized Complete Block (RCB) design with four replications. The seed categories were pre-basic, basic and certified seed of wheat varieties Bakhtawar-92 and Fakhri Sarhad from CCRI, Pirsabak and were compared with farmers seed of the same varieties collected from 4 location of the province. Maximum emergence m-2 (183) was recorded from pre-basic seed of Bakhtawar-92 and Fakhri Sarhad collected from CCRI, Pirsabak followed by basic and certified seed category of the same location. Farmers seed collected from Peshawar locality gave minimum emergence m-2 (73) among different seed categories. Pre-basic cateroy of Bakhtawar-92 obtained from CCRI, Pirsabak gave maximum spikes m-2 (347.3), grains spike-1 (52.30), biological yield (11500 kg ha-1), grain yield (4931 kg ha-1), thousand grain weight (52.75 g) and harvest index (43.11%), followed by basic and certified categories of the same varieties and location. Among farmers seed, Bakhtawar-92 collected from Charsadda and Nowshera locality performed better in all yield parameters as compared to other locations. Farmers seed collected from Peshawar and Mardan performed poorly in maximum yield parameters. It is concluded that pre-basic seed of Bakhtawar-92 and Fakhri Sarhad obtained from CCRI, Pirsabak showed better performance in all agronomic parameters and may be recommended for higher production under the agroclimatic conditions of NWFP-Pakistan.]]>Agrawal, A.P. and R.K.
