Abstract

An experiment was conducted in the Vegetable Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (Uttar Pradesh) Thirteen treatments having one cultivar were laid out in Randomized Block Design (RBD) with three replications. Find out the effect of nitrogen, phosphorus and Potassium (NPK) on growth, and yield of black cumin. On the basis of present investigation it is concluded that the application of treatment T6 70:65:65 (Urea=152.17kg/ha, Single Super Phosphate=406.25kg/ha, Murate of Pottash= 108.33kg/ha) was superior in terms of growth and yield viz. plant height (60.23), number of primary branches per plant (8.25), number of primary branches per plant (14.96), days to flower bud appearance (63.48), days to 50% flowering (56.46), number of capsule plant-1 (37.47), seed yield plant-1 (8.59g), seed yield plot-1 (103.12g) and seed yield (7.20q ha-1) of Black cumin.
