Ertragskomponenten und Wasserstressindex von Mungbohnen bei Defizitbewässerung

This study was conducted in 2018 growing season to determine the response of mung bean water stress. Effects different irrigation levels on yield and components potential use crop stress index (CWSI) scheduling were also investigated. Five (I100, I75, I50, I25 I0) applied through drip system. Amount supplied varied between 20–445 mm. Plant consumption (ET) values 125–521 The highest (163 kg/da) obtained from full-irrigation (I100) lowest (39.7 rain-fed (I0) treatment without irrigations. heights 58.6–21.2 cm, first pod 17.4–29.3 number branches per plant 1.00–2.77 pods 3.2–18.9. Water efficiency (WUE) 0.31–0.50 kg/m3 usage (IWUE) 0.37–0.77 kg/m3. Crop 0.13–0.93. lower limit (LL) equation as Tc-Ta = ?2.9674 × VPD + 4.1341 (R2 0.66) upper (UL) identified 9.7 °C. Highly significant (p < 0.01) correlations seen CWSI yield. Based present findings, I75 recommended under deficit conditions. 0.13–0.22 can be used initiate irrigations for drip-irrigated bean.
