The experiments were conducted to observe the impact of plant geometry and seed rates on growth, yield attributes, productivity as well as weed dynamics of wheat (Triticum aestivum L.). Experiment was laid out in split plot design with total 12 treatment combinations and replicated thrice. The treatment comprises of plant geometry (Broadcasting – M1, 25 cm Spacing – M2, 22.5 cm Spacing – M3 and 20 cm Spacing– M4) and seed rate (100 kg ha-1 - S1, 125 kg ha-1- S2 and 150 kg ha-1 -S3). The crop responded significantly better growth, yield attributes and yield with 22.5 cm plant geometry rather than other plant arrangement. In case of seed rate, 125 kg ha-1 was found most suitable to obtain the maximum yield. The weed population found in sowing of crop 25 cm apart and minimum weed population was observed under the sowing of crop 20 cm apart. The maximum number of weed population viz., Chenopodium album, Anagallis arvensis, Phalaris minor and Cyperus rotundus were observed maximum under the seed rate of 100 kg ha-1 and minimum number of weed population were also observed under the sowing of 150 kg ha-1 of seed rate. the maximum gross income (Rs 71722 ha-1) was obtained at 22.5 cm part which was higher other plant geometry, broadcasting (Rs 39728 ha-1) and 25 cm (rs 66949 ha-1). The maximum net return was recorded under the seed rate 125 kg ha-1 (Rs 47799 ha-1) than other seed 100 kg ha-1 and 150 kg ha-1. The highest benefit: cost ratio under 125 kg ha-1 seed rate which is significantly higher in comparison to 150 kg (3.30).
