Abstract
A field experiment was conducted during the rainy (kharif) season (July October) of 2000 and 2001 at Indian Agricultural Research Institute, New Delhi, to study the effect oi pianting geometry and nitrogen levels on growth, yield attributes, yield and nitrogen use efficiencies of PRH 10 scented hybrid rice (Oryza sativa L.). Planting ge ometry did not influence growth, yield attributes, yields and nitrogen use efficiency. However, each unit increase in N level led to significant increase in growth, yield attributing characters, and yield of rice.The maximum grain yield (65.5 qlha) was recorded with highest level of N.The maximum response was observed at 75 kg Nlha and thereaf ter it decreased with the increase in N level.The nitrogen use efficiency (NUE), apparent recovery (%), nitrogen ef ficiency ratio (NER) and physiological efficiency index of absorbed nitrogen (PEIN) were significantly higher at lower level of N and decreased significantly with increasing N levels.
