Field investigations were conducted during Rabi season of 2014 and 2015 to study the effect of different seeding rates on different genotypes of wheat crop when sown through seed cum fertilizer drill at farmer’s field in tribal areas of Gariyaband District in Chhattisgarh. The experiment was laid out in split plot design with three replications. Three wheat varieties (HD-2864, HD-2932 and MP-3336) were tested at 5 seeding rates (100,110,120,130 and 140 kg ha-1). Seed rate significantly affected all the plant traits. The results revealed that wheat sown at the seed rate of 140 kg ha-1 significantly showed promising results in terms of taller plants (70.89cm & 71.41cm), maximum number of effective tillers and m-2 (372.33 & 376.44), grains spike-1 (58.0 & 58.67), 1000 grain weight (39.64g & 39.78g) and grain yield (36.45 qha-1& 36.34 qha-1) during both the years respectively, in comparison to the other lower seed rates. This increase in yield was associated with the progressive increase in all growth and yield components. Among the varieties evaluated HD-2864 was most efficient and recorded maximum values of all the growth, yield attributes and yield.
