Abstract
The effect of irrigation practices and variable fertilizer was studied on the seed yield, stalk yield, and other plant growth characteristics of sunflower. The study was conducted at Malakandher Farm of NW.F.P. Agricultural University during kharif 1991. Crop water use efficiency and field water use efficiency were calculated using balance sheet method for the estimation of effective rainfall and pan evaporation method for the calculation of consumptive use of crop. The statistical analysis indicated that the effect of irrigation practice was significant at 5% and 1% probability levels. The effect of variable fertilizer was found insignificant, which might have occurred due to rainfall soon after the second irrigation. Under the prevailing circumstances the furrow irrigation method with an application of 18.28 cm of water during the growing season increased the weight of sunflower seed and stalk compared to basin irrigation method with an application of 30.48 cm of water. The same counts for the crop water use effect and field water use effect.
