A field experiment was conducted during 1993-94 at NWFP Agricultural University, Peshawar, Pakistan in order to study the productive efficiency of the newly designed geometry of planting, rows, 4th skip in 30 cm apart rows, 3rd row skip in 30 cm apart and 50 cm between pairs. Three seed rates, 50, 100, and 150 kg ha-1 were also studied. Maximum grain yield of 2395 kg ha-1 was obtained from the highest seeding rate of 150 kg ha-1. Row geometry had significant effects on spikes m-2 and thousand grains weight. Though, row geometry had no significant effect on grain yield, however, the geometry with 3rd row skip in 30 cm apart rows produced the highest yield of 2302 kg ha-1followed by 4th row skip in 30 cm apart rows geometry with 2291 kg ha-1. Plant height increased as increased the seed rate and planting geometry. The highest straw yields of 6407 and 6460 kg ha-1 were produced at the highest seed rate (150 kg seed ha- 1) and the narrowest planting geometry (pair of rows 30 cm apart and 50 cm between pairs), respectively. Planting geometry with 4th row skip in 30 cm apart rows, and sowing rate of 50 kg seed ha-1 gave the highest harvest indices of 28.12 and 27.73 % respectively. It was found that wider row geometry technology could be adapted without having any adverse effect on the ultimate grain yield. This system besides facilitating interculture, also permits convenient intercropping in wheat during vegetative growth period.
