Responses of Irrigation and Fertilizers on the Growth and Yield of <i>Hordeum vulgare</i> L.
An experiment was conducted to study the influence of soil moisture, NPK fertilizers and variety on yield and yield components of barley (Hordeum vulgare L.). Plant height, tiller number, extrusion length, spikelet number, plant weight, grain number, 100-grain weight and grain yield were observed highest in the I2 (40 mm irrigation water) and F3 (120N 75P 45K) treatments. I2 (40 mm irrigation water ) and F3 (120N 75P 45K) treatments had the highest consumptive water use (CWU). But the highest water use efficiency (WUE) was observed in the I0 (no irrigation) and F3 treatments. Cultivar BARI-Barley-2 had the highest CWU, while cultivar BL-1 had the highest WUE.
Key words: Barley; Irrigation; Fertilizer; Grain yield; Consumptive water use; Water use efficiency.
