Optimization of sowing and fertilizer requirement of barley (Hordeum vulgare) under irrigated condition

A field experiment was carried out at Wheat Research Station, Gujarat Agricultural University, Vijapur, during the winter seasons of 1996–97,1997-98 and 1998–99, to find out the appropriate sowing time (15, 30 November and 15 December), nitrogen (60, 80 and 100 kg/ha) and phosphorus (0, 20 and 40 kg/ha) requirement of barley (Hordeum vulgare L). Sowing time and fertilizer levels positively influenced the productivity. Timely sown, i.e. 15 and 30 November, crop resulted in significantly better grain and straw yields than the late-sown (15 December). Nitrogen 100 kg/ha, being at par with 80 kg/ha, was superior to 60 kg/ha in respect of grain and straw yields. Among the phosphorus levels, higher grain yield achieved under 40 kg P2O/ha over the lower levels. Significantly higher N and P uptake was recorded in 15 November sown crop. Application of N 80 kg/ha and P 40 kg/ha also recorded significant values for nutrient uptake. Sowing of barley during the second fortnight of November and nourished with 80 kg N/ha and 40 kg P/ha fetched better profit.
