Effect of different levels of NPK on growth and yield of brinjal (Solanum melongena L.)

A field trial was conducted to evaluate the effect of different levels of NPK on the growth and yield of brinjal (Solanum melongena L.). The experiment comprised five treatments with different NPK levels i.e. control, 50:25:25 kg ha-1, 75:37.5:37.5 kg ha-1, 100:50:50 kg ha-1 and 125:62.5:62.5 kg ha-1 and replicated three times. Results indicated that growth parameters such as plant height, number of leaves per plant, number of branches per plant, and branch length, as well as yield parameters like the number of fruits per plant, fruit length, fruit diameter, fruit weight, and yield per plant, were significantly highest with T5 (125:62.5:62.5 kg NPK ha-1), followed by T4. The lowest values were observed in the control treatment.
