Integrated Application of K and Zn as an Avenue to Promote Sugar Beet Yield, Industrial Sugar Quality, and K-Use Efficiency in a Salty Semi-Arid Agro-Ecosystem

چکیده
Salinity combined with a deficiency of potassium (K) and zinc (Zn) negatively affect sugar beet yield quality. A two-year (2017/18–2018/19) field trial was undertaken to investigate the mediating role soil-applied K [120 (K120) 180 (K180) kg ha?1] foliar-applied Zn [0 (Zn0), 150 (Zn150), 300 (Zn300) ppm] in alleviating salt-stress (8.60 dS m?1) based on morpho-physiological responses, quality, K-use efficiency BTS 301 Kawemira cultivars. Application K180 × Zn300 more effective resulted 23.39 37.78% higher root (RY) pure (PSY), respectively, compared control (K120 Zn0). It also enhanced sucrose, (PS), purity but decreased impurities (?-amino N, K, Na), alkalinity index, loss. However, K120 recorded efficiency. PSY correlated positively (r = 0.776 **, 0.629 0.602 0.549 0.513 **) RY, fresh weight (RFW), top yield, PS, diameter, respectively. The stepwise path-coefficient analysis demonstrated that RFW were most influential PSY-affected attributes. Integration + can correct deficiencies soil mitigate effects via improving growth,

Nitrogen effects on yield, quality and K/Na selectivity of sugar beets grown on clays under semi-arid, irrigated conditions
In a four-year experiment, five nitrogen rates (0, 60, 120, 180 and 240 kg N ha-1) were tested over irrigated sugar beets grown on clays, underMediterranean conditions, in centralGreece. There, sugar beets are commonly grown under water shortages, high temperatures and high soil Na concentrations. Contrary to previous reports, N rates did not affect significantly population density (as asse...
متن کاملDevelopment of a New Model to Estimate the Technical Quality of Sugar Beet in the Semi – Arid Climate
Determination of the amount of sugar in sugar beet is usually accomplished by polarimetric method in sugar industry. This method is not accurate due to impurities such as sodium, potassium and amino-nitrogen that are present and might cause some errors in the evaluation of the technical quality of sugar beet. In this research, 7309 samples of sugar beet from two semi- arid county, Isfahan and C...

construction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
