GROWTH, YIELD AND QUALITY OF NIGELLA (Nigella sativa L.) AS INFLUENCED BY ROW SPACING AND NITROGEN LEVELS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 52
Abstract
An experiment was conducted during Rabi season of 20015-16 at Horticultural experimental farm, College of Horticulture, Mandsaur to study the effect of row spacing and nitrogen levels on growth, yield and quality of Nigella. The experiment was conducted in split plot design having 3 row spacing (15 cm, 22.5cm and 30cm) in main plot and 3 levels of nitrogen (20, 40 and 60 Kg N ha-1) in sub plot. Wider row spacing of 30 cm significantly increased the plant height, number of branches per plant, fresh and dry weight of plant, number of capsules per plant (25.94), number of seed per capsule (72.71), test weight (2.29 g), seed yield (12.18 q ha-1), straw yield (22.98 q ha-1), biological yield (35.16 q ha-1), protein content in seed (21,25%) and oil content in seed (0.77 %). Further, these attributes were minimum in treatment 15 cm row spacing. Whereas, non significant effect was observed in harvest index (%). Among various levels of nitrogen applied 60 kg N ha-1 higher growth, yield and quality attributes. Application of 60 Kg N ha-1 significantly increased the growth attributes like plant height (79.11 cm), number of branches per plant (8.88) fresh weight per plant (78.77 g) and dry weight of plant (19.51 g) at harvest. Similarly, 60 kg N ha-1 significantly increased the capsules per plant (24.31), seed per capsules (63.90), test weight (2.24 g), seed yield (11.72 q ha-1), straw yield (20.87 q ha-1), biological yield (32.59 q ha-1), protein content in seed (20.35%) and oil content in seed (0.77%). Thus, the sowing of nigella at 30 cm row spacing and application of 60 kg N ha-1 gave significantly higher growth, yield and quality of nigella.
