Abstract:
The investigation entitled “Study on effect of surface seeding, seed rate and seed priming on yield of field pea under rice-based utera cropping system” was conducted at Research cum Instructional Farm, I.G.K.V, Raipur (C.G.). The main objective was to evaluate the effect of surface seeding, seed rate and seed priming on yield attributes of field pea taken as utera crop. The soil of the experimental field was vertisol with low, medium and high content of N, P and K, respectively and neutral in reaction. The test variety was Indira Matar-1. The experiment was laid out in Randomized Block Design having three replications and nine treatments viz. T₁: Dry surface seeding 80 kg ha^-1, T₂: Dry surface seeding 100 kg ha^-1, T₃: Dry surface seeding 120 kg ha^-1, T₄: Soaked seed surface seeding 80 kg ha^-1, T₅: Soaked seed surface seeding 100 kg ha^-1, T₆: Soaked seed surface seeding 120 kg ha^-1, T₇: Seed priming (1% KNO3) 80 kg ha^-1, T₈: Seed priming (1% KNO3) 100 kg ha^-1 and T₉: Seed priming (1% KNO3) 120 kg ha^-1. The results revealed that treatment T₉: seed priming (1% KNO₃) 120 kg ha^-1, gave highest seed yield (1058 kg ha^-1) and stover yield (2290 kg ha^-1), but it remained at par with T₈: seed priming (1% KNO₃) 100 kg ha^-1 and T₆: soaked seed surface seeding 120 kg ha^-1.
