effects of potassium application under different irrigation intervals on yield and water use efficiency of two genotypes of sugar beet in furrow irrigation
نویسندگان
چکیده
experiments were conducted in 1998 and 1999 to study the effects of different levels of potassium and irrigation intervals on yield and water use efficiency of two genotypes of sugar beet (a37.1 and 12681) in khorasan agricultural research center (torogh, iran). potassium levels were; no potassium application, increasing potassium to 5% of soil cation exchange capacity (cec) and second treatment plus plant requirment to potassium. irrigation interval were 9, 12, 15 and 18 days. in 1998, the amount of water in each irrigation was based on local farmer usage (that is 739 mm). in 1999, for increasing water stress, the amount of water decreased 25% as compared to the previous year. root yield and white sugar yield in two years and water use efficiency in first year were significantly affected by irrigation amount (p

Effects of different irrigation methods and hormone application on water use efficiency, yield, and leaf biochemical traits in potato
Investigation of different irrigation methods on plants is necessary due to limited water resources and the increasing need for food products. The purpose of this study was to evaluate the effect of sprinkler and drip irrigation systems and hormones on morphological and physiological characteristics of potato. Treatments included sprinkler and drip irrigation systems and hormones (gibbere...
متن کاملYield and water use efficiency of early potato grown under different irrigation regimes
Potato grown for early or off-season production plays a crucial role in the economy of several areas in the Mediterranean countries. Irrigation is important for determining yield and earliness, thus a better investigation of plant response under various pedo-climatic conditions can help to improve resource use efficiency and farmer income. A two-year field research (2009-2010) was carried o...
