EFFECT OF DIFFERENT RATES OF PHOSPHOR SAND POTASSIUM FERTILIZATION ON FRUIT PRODUCTION AND QUALITY OF STRAWBERRY CV. CHANDLER.
This study was carried out to elucidate the response of strawberry cv.
Chandler 102 levels of P·Fertilizer (31 and S2Kg P20:YFed.) and 3 levels f K fertilizer (240 Kg 1<20/Fed. as soil application (SA), 120 Kg K20 as soil application (SA) + 120 Kg K20 as loliar spray (FS), and 240 Kg 1<20 (SA) + 120 K20 (FS)/Fe . as well as Iheir combinations.
Obtained results show that P·appUcation had favorable i"flue~s on plan, growth and early and total yieldlFed. P.supply at 31Kg P20sfFed increased fruit welghl, whereas p. supply al62Kg P205iFed increased fruit firmness and lolal soluble solids. it also increased K% but did not on N% in fruit.
Results also show thai applying K·fertilizer at 240 Kg 1<20 (SAr. or 120 Kg K20(SA) + 120Kg K20 (FS)/Fed. gave the highest early and total yield/Fed. K supply at 240 Kg K20 (SA)/Fed increased frull firmness in March haNssting whereas K app6catfon at 120 Kg 1<20 (SA) + 120Kg KlO (FS)/Fed. gave the hig[est values conceming fruit T.S.S% and total acid~y (TA)%. K-1ectilization at the fate .ro Kg KzO (SA)/Fed gave the highest levels of N,P and K contents of fruit <XJmpnring ilh other K levels used.
Obtained data indicated thal application of 62 Kg P20S +240 Kg ~O as soil application /Fed. gave the highesl early and tolal yield with fruiw of high firmness which Increase the fruit ability to shipping and marlceting. Such result COuld be recommended.
