Abstract: A set of two experiments were conducted to evaluate the potential of wheat grain yield against seed rate and integrated use of fertilizer (organic and inorganic). The study was carried out during 2016-18 in the field area of Faculty of Agriculture, Gomal University, Dera Ismail Khan, Khyberpakhtun Khwan-Pakistan. Both the experiments were laid out in randomized complete block design with seven treatments (T1 to T7) under four replications. The results of first experiment (impact of seed rate on grain yield) indicated that there was a negative correlation between seed rate and no of tillers. As seed rate increased, no of tillers decreased. Although, grain yield increased with an increase in seed rates but 1000 grain weight and grain yield exhibited non-significant differences during both the years. Maximum grain yield was obtained, with integrated use of chemical fertilizer and farm yard manure (Experiment No.2), at 20 t ha-1 FYM + 138 kg P2 O5 and 120kg ha-1 N during consecutive years.
