| Popis: | A Field experiment was conducted at Research Farm, Chaudhary Charan Singh Haryana Agricultural University, Hisar, during the kharif seasons of 2004 and 2005 to find out suitable spacing for pearlmillet hybrids along with nitrogen and phosphorus levels to increase the productivity and quality of pearlmillet. The experiment was laid out in split plot design allocating two hybrids and three plant densities in main plots and four fertility levels in sub plots replicated thrice. Highest grain yield (35.3 q/ha) was recorded when the crop was sown at a spacing of 45 t 12 cm and fertilized with 90 kg N + 45 kg P2O5 ha-1 but was at par with 60 kg N + 30 kg P2O5 ha-1. Pearlmillet HHB 67-2 recorded relatively higher value for consumptive water used and water use efficiency. This hybrid also fetched highest protein yield. Wider spacing (60 t 12 cm) resulted significantly higher protein content over closer spacing but 45 t 15 cm spacing resulted into higher protein yield. Further higher protein yield was harvested when the crop was fertilized with 90 kg N + 45 kg P2O5 ha-1. |
