Abstract

The current study, which was conducted at the Agricultural Research Farm of Rama University in Mandhana, Kanpur, India, was titled Effect of varying amounts of Nitrogen (N), Phosphorus (P2O5), and Potassium (K2O) on growth and development of Sweet Orange (Citrus sinesis Osbeck) plants. In terms of maximum plant height (83.57 cm), maximum number of leaves (421.04), maximum number of branches (26.36), maximum stem diameter (3.04 cm), maximum spread of canopy (42.36 cm), maximum length of inter-nodes (9.68 cm), and maximum chlorophyll content (4.58 mg/g), the results showed that treatment T2 (850 g / plant Nitrogen, 600 g / plant Phosphorus, and 850 g / plant Potash) achieved the best results followed by treatment T9 (800 g / plant Nitrogen, 400 g / plant Phosphorus and500 g / plant Potash) and the minimum was recorded in T4(700g / plant Nitrogen, 400g / plant Phosphorus and 400g / plant Potash).
