Abstract:
The present research titled “Effect of different doses of nitrogen on growth and yield of brinjal (Solanum melongena) Rama University, Mandana, Kanpur was undertaken with the objective of assessing the effect of different doses of nitrogen on growth and yield of brinjal from February to June, 2021. The experiment was carried out in Randomized Complete Block Design. There were 5 treatments comprising T₁ (0 kg N/ha), T₂ (50 kg N/ha), T₃ (100 kg N/ha), T₄ (150 kg N/ha) and T₅ (200 kg N/ha) which was replicated four times. Application of 150 kg N/ha showed maximum plant height and plant spreading at 30 DAT (38.825 cm and 137.85 cm), 60 DAT (38.825 cm and 52.40 cm) and 90 DAT (93.95 cm and 94.04 cm respectively) along with highest number of branches per plant (14.02) followed by 200 kg N/ha compared to control treatment. Least days taken to first flowering (48.45 days), and days taken to 50% flowering (77.50 days) was observed in T₄ (150 kg N/ha) with highest fruit length (25.34 cm), average weight of fruit (175.4 g), and fruit diameter (3.890 g). Application of 150 kg N/ha also recorded higher yield per plant (7.937 g) and yield per hectare (38.693 t/ha) compared to control treatment. The results showed that the Nitrogen showed significant effect on all growth and yield parameter of brinjal. It is also suggested that 150 kg N/ha is more favourable for production of brinjal and maintenance of soil environment.
