Abstract:
The aim of this research was to determine the effect of different levels of potassium on growth and yield of different blackgram varieties. A field experiment was conducted during Kharif 2021, at College of Agriculture, Central Agriculture University, Imphal, Manipur. The soil of experiment plot was clay in texture, nearly acidic in soil reaction (pH 5.96), medium organic carbon (0.75%), available N was low (280.39 Kg/ha), medium available P₂O₅ (188.16 Kg/ha) and available K₂O (20.67 Kg/ha). The observations of twelve treatments were replicated thrice with factors potassium levels (0, 20, 30 and 40 Kg K₂O ha^-1) and Varieties (Pant U-31, Uttara and CAU BG-1) in a Factorial Randomized Block Design the findings shows that growth and yield attributes viz. The result showed that higher plant height (38.34 cm), Maximum number of branches (6.00), Maximum fresh weight (49.10), maximum dry weight (13.13), higher pod length (4.66), highest number of pods per plant (36.01), seed yield (1125 Kg/ha) were significantly recorded with 40 Kg K₂O ha^-1.
