Abstract
Five experiments were conducted to determine the response of wheat (Triticum Aestivum L) to row spacing, Nitrogen, Seed rate and Sowing Technique. Ten wheat varieties were compared for different agronomic traits at agronomic research area, Faculty of Agriculture, Gomal University, D.I.Khan. Based on the yield components and grain yield, these varieties are ranked as Inqilab-91> Sughat> Daman-98> Pirsabak-91> Bakhtawar-92> Dera-98> MH-97> Sulaiman-96> Punjab-96> Sarsabz.

The effect of different row spacing in wheat variety Inqilab-91, revealed significant effect on tillers m-2, number of spikes m-2, 1000-grain weight, biological yield and grain yield. Highest number of spikes, biological yield and grain yield were obtained from cross sowing technique (30 x 30cm2).

In an other experiment the effect of different nitrogen levels (0, 50, 100, 150 and 200 kg ha-1) on four wheat varieties viz. Daman-98, Raj, Bakhtawar-92 and Inqilab-91 was studied. Different nitrogen levels significantly affected plant height, number of spike m-2, spike weight, biological yield, grain yield and grain protein content positively. Among wheat varieties Daman-98 and inqilab-91 produced toe maximum plant. height, spike weight, grains spike-1, 1000-grain weight, biological yield and grain yield. Grain yield and biological yield were statistically similar at the doses of 150 kg N ha-1 and 200 kg N ha-l. Among varieties Daman-98 and Inqilab-91 proved to be the best varieties. However, the protein content of wheat grains increased with an increase in nitrogen.

Six wheat varieties (Daman-98, Raj, Punjab-96, Inqilab-91, Dera-98 and Bakhtawar-92) were tested at seed rates of 50, 100, 150 and 200 kg ha-1 during 1999-2000 and 2000-2001. Among varieties, Daman-98 produced significantly taller plants, maximum spike weight, spike length, number of grains, heavier grains and maximum grain protein content. Interaction among varieties and seed rates indicated that maximum grain yield was produced by Daman-98 in plots where seed rate of 200 kg ha-1 was used during both years which were statistically at par with grain yield of Inqilab-91 and Bakhtawar-92.

Keeping in view the result of cross sowing technique in the row spacing experiment, a comparative study of routine sowing technique with cross sowing technique for yield components and grain yield was conducted during 2000-2001 and 2001-2002. Cross sowing technique (30 x 30 cm2) with cultivar Dera-98 produced maximum grain yield as compared to routine sowing technique. (30 cm single row) in both years. The results revealed that cross sowing technique of 30 x 30 cm2 and varieties significantly affected the plant height, spikes m-2, grains spike-1, 1000 grain weight, biological yield, straw yield and grain yield. Interaction among cultivars and sowing techniques was also found significant. So it is concluded from these results that cross sowing technique (either 30x 30 cm2 or 45 x 45 cm2) are the best way of obtaining the higher grain yield using seed of any improved variety of wheat under agro-ecological conditions of Dera Ismail Khan.
