ABSTRACT
The present study was carried out to observe the effect of applying N, P and K fertilizers at different rates and combinations on growth and yield of rice line PB-95. The fertilizer treatments comprised the T1 (control), T2 (0-75-75), T3 (60-75-75), T4(120-75-75), T5 (180-75-75), T6 (120-0-75), T7 (120-500-75), T8 (120-100-75), T9 (120-75-0), T10 ((120-75-50) and T11 (120-75-100) NPK kg ha-1. The results showed that application of NPK significantly increased the crop yield and maximum paddy and straw yield were obtained from plot fertilized @ 120-100-75 NPK kg ha-1. Harvest Index was highest at control, N physiological efficiency index and N fertilizer efficiency decreased with increasing N levels. Similarly, P physiological efficiency index decreased while P fertilizer efficiency increased with increasing P levels.
