ABSTRACT
Two field experiments were performed at the Experimental Farm of
Ismailia Agricultural Research station farm during 2014/15 and 2015/16
seasons. This study aimed to identify effectiveness of foliar spraying with
three doses of potassium i.e. zero, 1.5 and 3g/L and three rates of
micronutrients i.e. zero, 200 and 300 ppm and their interaction in improving
straw and seed yields and their components of Giza 9 flax cultivar under
sandy soil conditions. The results indicated that increasing dose of
potassium foliar spraying from zero up to 3g/L significantly increased straw,
seed yields and their components. Increasing rate of micronutrients foliar
application from zero up to 300 ppm had significant effect on all characters
studied except for fiber percentage appeared insignificant effect. Significant
interaction between potassium and micronutrients foliar application were
recorded in technical stem length, main stem diameter, straw yield/plant,
straw yield/ fad and seed yield/ fad.
