Effect of Seed Treatment and Nutrient Schedule on the Productivity of Blackgram (Vigna mungo L.)

Background: Blackgram (Vigna mungo L.) is an important short duration crop and grown throughout the country. Seed treatment can improve seedling establishment better stand; it also improves plants ability to tolerate stress at early growth stages foliar application has advantage of quick efficient utilization nutrients, elimination nutrient losses through leaching fixation in soil helps regulating uptake nutrients by thus improving productivity. Methods: A field experiment was conducted during rabi 2018 Instructional Farm, College Agriculture, Vellayani, Thiruvananthapuram assess effect different levels seed treatments schedule on yield blackgram. The attributes, attributes viz., number pods per plant, seeds pod, length 100 weight, grain yield, haulm harvest index were favorably influenced treatments. Result: with borax @ 1 g kg-1 sodium molybdate observed superior increasing plant height (135.84 cm), trifoliate leaves (7.61), (24.16), pod (5.23 weight (6.74 g), (1005 kg ha-1) (0.38). Significantly higher nodule (41.83), effective (33.83) nodules (58.83 mg) plant-1 flowering documented seed. In case significantly (7.33) 2 maximum (1854 reported basal ½ N + full P K followed as spray 13:0:45 15, 30, 45 60 DAS produced more (6.52 (872 (1750 ha-1). Interaction boron molybdenum showed significant influence respect yield.
