In India pulses production and productivity is low and inadequate to meet the demand of nation. The alternate option to increase the pulse production is through seed amelioration by combining the seed hardening, coating and pelleting techniques. The current study was aimed to evaluate integrated seed treatment on seed yield and quality in blackgram. The seeds were first preconditioned by keeping them in between two layers of moist gunny bag for one hour. Then, the preconditioned seeds were soaked for three hours in 100 ppm ZnSO₄ solution at 1/3 volume of seeds and shade dried to their original moisture content (hardened seed). Then the hardened seeds were supplemented with Polymer 3 ml/kg + Carbendazim 2 g/kg + Imidacloprid 1 ml/kg for integrated seed treatment and field experiments were carried out along with untreated seed. Among the seed treatments, integrated seed treatment recorded higher pod set per cent (84.00), number of pods/plant (52.00 pod yield/plant (27.60 g), pod yield/ha (752 kg), number of seeds/pod (6.00), seed yield/plant (17.6 g) and seed yield/ha (590 kg) which were respectively 3.70, 8.33, 4.15, 3.01, 20.00, 4.14 and 1.89 per cent higher than mere hardened and untreated control seeds thus suggesting that integrated seed treatment can be recommended for improving the productivity of blackgram.
