Abstract

Nitrogen is prone to serious losses (more than 50%) under paddy field conditions. Splitting fertilizer-N (to supply N-demands of RICE s growth in key stages) is an imperative practice in fertilizer dressing management in paddy fields. This study was under taken to provide information to how the RICE variety (improved var. shafagh) will respond to some best (recommended) split of fertilizer-N (urea) and some N-spray at heading stage, while hill spacing is quite densely (20cm×20cm) established.For the improved variety of shafagh, different N-splitting treatments could not significantly prove any superiority as far as RICE YIELD was concerned, and the same was true for different N-spray treatments at heading stage. But all the 3 best N-splitting could bring the YIELD level much higher (at least 1.5 ton per hectare) than ever obtained by this variety in the region. In fact, this completely new YIELD level (9160 kg ha-1) for the variety of shafagh which was obtained under densely plant population (20cm x 20cm) is a new challenge for RICE production in the region. Challenge for sustainability of the new YIELD increase (1.5 tons per hectare) will open the scope in research to involve new farming practices.
