Effect of NPK fertilizers on growth, yield attributes and economics of Melia dubia

A field experiment was conducted to study the effect of different levels of NPK on the performance of Melia dubia. Treatments consist of three levels of nitrogen (150, 250 and 350 g N plant⁻¹), two levels of phosphorus (75 and 150 g P plant⁻¹) and two levels of potassium (150 and 300 g K plant⁻¹) were tried in RBD replicated three times. The experiment was conducted in a soil having red sandy loam in texture, non-calcareous, neutral in reaction with low nitrogen and phosphorus and medium in available potassium. The growth attributes viz., plant height, collar diameter and volume index were recorded. The growth attributes were influenced by N, P and K at different levels. Among N, P and K levels, the application of 250:150:150 g NPK plant⁻¹(T4) influenced significantly the growth attributes followed by 250:75:150 g NPK plant⁻¹(T3).
