Response of potato plants for different sources of potassium with different foliar rates of boron and molybdenum [electronic resource].

Includes references.

Two field experiments were conducted during the two successive fall seasons of 200212003 and 200312004 on potato cVo Spunta at EL-Zahraa village, Mansoura, Egypt, to study effect of two potassium sources (SUlphate or chloride) at the recommended rate and so different foiiar spraying rates of boron (50 and 75 ppm) or/pius molybdenum (25 and 50 ppm) twice at 60 and 75 DAP, in addition to their interactions on vegetative growth characters, tubers quality, tuber minerals content and total tuber yield. The resuits indicated - generally - that K2S0, application was mar" effective than KCL on the vegetative growth parameters, tuber quality characters and the yield and its components. Application of K,sO, led to higher tubers yield production (8.9511.33 %) than KCL application during the 1st and 2nd seasons, respectively. Foliar spraying of potato plants with (8 at 75 ppm + Mo at 50 ppm) twice at 60 and 75 DAP was significantly increased most vegetative growth parameters and led to in improve the tuber quality parameters i.e. dry matter, starch, specific gravity and the protein of tUber, as well as, the tuber weight and total tuber yield compared with the other treatments in both seasonso
