حجم آب مصرفي یکي از فاكتورهاي مهم در آبیاري محصولات كشاورزي بوده و در حجمهاي مختلف آبیاري با توجه به ایجاد شرایط متفاوت رطوبتي خاک در طول فصل رشد و همچنین، امکان شستشوي مواد مقدار محصول ميتواند تحت تاثیر قرار گرفته و متفاوت ، غذایي خاک در اثر اعمال حجمهاي بالاي آبیاري باشد. این پژوهش با هدف بررسي تأثیر حجمهاي مختلف آب آبیاري بر عملکرد كینوا رقم تیتیکاكا در 13922 تا 3322 كشت بهاره در یزد انجام شد. بدین منظور شش تیمار حجمهاي مختلف آب آبیاري تعریف و در قالب طرح بلوکهاي كامل تصادفي با سه تکرار اعمال گردیدند. آبیاري با استفاده از سیستم قطرهاي (تیپ) انجام و تیمارهاي مختلف حجم آب آبیاري با اعمال گردیدند.

The amount of applied water is one of the important factors in crops irrigation, and the amount of production can be varied in different applied water, depending on the different soil moisture content as well as the possibility of soil nutrients leaching due to high volumes of irrigation. This study was done to investigate the effects of different irrigation water volume on yield of quinoa (Titicaca cultivar) in spring planting at Yazd. For this purpose, different volumes of irrigation water (from 3300 to 13600 m3.ha-1 for the entire growing season) were examined in a randomized complete block design with three replications. Irrigation was carried out with using a drip irrigation system (tape), and the different irrigation volumes were applied with varying irrigation interval from 3 to 20 days and keeping constant irrigation depth at each irrigation. Electrical conductivity of irrigation water was 10 dS.m-1, and volume of used water in each irrigation was measured by a water counter. At the end of growing season, some parameters such as plant height, panicle length and width, panicle number per plant, stem diameter, 1000 seed weight, biomass yield, seed yield and harvest index were measured and compared. The results showed significant effect of applied water on all measured parameters, except panicle width and panicle number per plant. The highest biomass (970 g.m-2) was observed in the 5700 m3.ha-1 treatment of applied water with 10 days irrigation frequency, the highest seed yield (320 g.m-2) and the highest harvest index (39.14%) were observed in 13600 m3.ha-1 treatment of applied water with 3 days irrigation frequency. The results of correlation coefficients showed that seed yield was significantly correlated with 1000seed weight (R2=0.821**) and panicle length (R2=0.711**). In addition, water use efficiency of quinoa varied from 0.24 to 0.62 kg.m-3 at different treatments of applied water. According to this index, the optimum irrigation frequency of quinoa and the applied water volume by the drip irrigation system (tape) were about 14 days and 4350 m3.ha-1, respectively, which is recommended under conditions the similar to this study.
