Effect of Different Irrigation Water Levels on Yield and Quality Parameters of Fodder Beet
Abstract
The study was carried out at the Agricultural Research and Application Farm of Faculty of Agriculture, Isparta University of Applied Sciencesin 2021, with the aim of determining the effect of different irrigation water levels on the yield and quality parameters of fodder beet by the experiment of randomized complete block design with three replications. The study used Rota fodder beet variety. Applied irrigation water amounts were determined according to Penman-Montheith method by considering the total reference evapotranspiration (ETo) of ten days for five different ratios (S1: ETo×1.20, S2: ETo×0.90, S3: ETo×0.60, S4: ETo×0.30; S5: ETo×0.00). Drip irrigation method was used for irrigation. Applied irrigation water amounts ranged between 131.9 mm – 643.6 mm. Crop water consumption (ET) ranged between 337.1 mm – 782 mm. At the end of the treatments, it was observed that fresh leaf yield varied between 570 and 1788.1 kg da-1 while these values were from 1865.7 to 7838.8 kg da-1 for fresh root yield, from 2435.8 to 9626.9 kg da-1 for total fresh yield, from 134.1 to 255.5 kg da-1 for leaf dry matter yield, from 469.9 to 1247.6 kg da-1 for root dry mater , from 12.2 cm to 25.4 cm for tuber length, and from 6.5 to 12.4 cm for tuber diameter. The yield response factor (ky) was 1.04. The water use efficiency was 72.3 – 145.0 kg ha-1 mm-1, the irrigation water use efficiency was ranged from 111.7 to 157.5 kg ha-1 mm-1. The S2 irrigation treatment was the most appropriate irrigation program under adequate irrigation water conditions. In terms of irrigation deficit conditions, results indicated that there may apply irrigation water at 60% or 30% of reference evapotranspiration from S3 or S4 irrigation program.
