Abstract: A field experiment was conducted for 3 consecutive years (2012 to 2014) on clay loam soil at Pearl millet Research Station, Junagadh Agricultural University, Jamnagar, Gujarat to study the appropriate nitrogen (0, 60, 80 and 100 kg/ha) and phosphorus (0, 15, 30 and 45 kg/ha) requirement of newly developed pearl millet (Pennisetum glaucum L.) hybrid to realize their maximum production potentiality under Saurashtra conditions. The pooled results revealed that the growth parameters, viz. plant height and total tillers/plant and yield attributes, viz. effective tillers/plant and test weight were increased with increasing nitrogen levels. Nitrogen 100 kg/ha (3146 kg/ha), was superior to 60 and 80 kg/ha in respect of grain yield, while in case of stover yield, 100 kg N/ha (4821 kg/ha), being at par with 80 kg/ha and significantly higher over 60 kg/ha. Moreover, maximum net returns (Rs 33124) and B:C ratio (2.63) was also recorded by the same treatment. Among the phosphorus levels, 45 kg P2O5/ha, being at par with 30 kg/ha was superior to 15 kg/ha in respect of grain (2768 kg/ha) and stover (4300 kg/ha) yields. The highest net returns (Rs 27213) and B:C ratio (2.17) was recorded with 45 and 15 kg P2O5/ha, respectively.
