Abstract

Experiment was conducted to study the response of different wheat varieties to various seed rates. The experiment consists of five different wheat varieties (V1 = Nasir - 2k, V2 = Salim - 2k, V3 = Bakhtawar-92, V4 = Fakhre-e-Sarhad and V5 = Lucky J-03) were sown at five various seed rates (S1 = 60 kg ha-1, S2 = 80 kg ha-1, S3 = 100 kg ha-1, S4 = 120 kg ha-1 and S5 = 140 kg ha-1). Data recorded from the varieties treatments revealed that maximum tillers m-2 (377), leaf area index (4.10), grains spike-1 (68), 1000-grain weight (45.24 g), grain yield (4022 kg ha-1), biological yield (16660 kg ha-1), net income (Rs. 61921), BCR (4.99 %) and MRR % (499.49) was noted from the plots sown with variety Fakhr-e-Sarhad. Statistical analysis of the data also revealed that seed rates were significantly affected all parameters except biological yield and harvest index. It can be inferred from the data showed that maximum ((369) tillers m-2, grains spike-1 (65), leaf area index (4.03), 1000-grain weight (45.30 g), grain yield (4222 kg ha-1), biological yield (15030 kg ha-1), net income (Rs. 62119), BCR (5.18 %) and MRR % (518.03) was noted from the plots seeded with 120 kg ha-1. In case of interaction between varieties and seed rate it was observed that maximum (420.25) tillers m-2, leaf area index (4.79), grains spike-1 (74), 1000-grain weight (47.33 g), grain yield (4676 kg ha-1), biological yield (19535 kg ha-1), net income (Rs. 66863), BCR (5.47 %) and MRR % (546.95) was noted from the plots sown with FakhreSarhad and seed rate was used at120 kg ha-1.
