Abstract

The increasing demand for food as a result of population growth has led to more pressure on the limited water resources for irrigation. For this reason, increase of yield per unit of water is more important as compared with yield per unit of land. Chemical nutrients are taken up by plant roots in solution form. Thus, an adequate amount of soil moisture is essential to facilitate this process. The objective of this study was to investigate the effect of various irrigation amounts on YIELD COMPONENTS, efficiency of applied water and fertilizers when used as FERTIGATION. Consequently, a field experiment was carried out with SUNFLOWER (Helianthus Annuus L.) as a complete randomized design with 20 treatments and 3 replicates. The fertilizers were applied by FERTIGATION. Four levels of the water (60, 80, 100 and 120% treatments I1 to I4) and five rates of the recommended fertilizers (0, 60, 80, 100, and 120% treatments F0 to F4) were applied. The results indicated that in FERTIGATION method, there were significant differences (p£1%) in total dry matter, grain yield and biomass between treatments.Treatment 14 with 10221 kg ha-1 dry matter, 7365 kg ha-1 biomass, and 2856 kg ha-1 grain yield and treatment II with 6051 kg ha-1 dry matter, 4292 kg ha-1 biomass, and 1760 kg ha-1 gr, ain yield had maximum and minimum yield respectively. Also treatment F1 with 8554 kg ha-1 dry matter, 3301.57 kg ha-1 grain, and treatment F0 with 7065.3 kg ha-1 dry matter had maximum and minimum yield respectively. There were significant differences in WATER USE EFFICIENCY (WUE) between 14 and other treatments. On the basis of dry matter WUE, and grain yield WUE, treatment I4 with 1.07 and 0.30 kg m3 had maximum WUE respectively. The results showed that by increasing yield, WATER USE EFFICIENCY increased and affected by fertilizers treatments. The results indicated that FERTIGATION method provided the nutrients in readily available forms for plant uptake. Thus due to higher availability of nutrients, yield and fertilizer use efficiency increased, which in turn increased the WATER USE EFFICIENCY.
