The purpose of this research is to investigate the effect of potassium fertilizer source by fertigation on strawberry productivity and quality parameters. The trial was conducted during 2015-2016 in the experimental greenhouse of the Hassan II Agronomic and Veterinary Sciences of Rabat. Strawberry plants of the cultivar ‘Fortuna’ were planted on October 13th in 40 liter pots equipped with a gravity fertigation system. Tested treatments were (1) Potassium sulfate for the whole growing cycle (PS/PS) (2) Potassium Nitrate during the vegetative period and Potassium sulfate during the fruit production period (PN/PS) and (3) potassium Nitrate for the whole growing cycle (PN/PN). An experimental block design with three repetitions was adopted. The total amounts of applied nitrogen, phosphorus, potassium, magnesium and calcium are identical for all potassium source treatments. Potassium sulfate has a slightly higher electrical conductivity than potassium nitrate source, 1.9 dS/m and 1.6 dS/m respectively. While the two solutions have a semilar pH of 6.1. The average yield obtained is 900 g with a slight advantage for the PN/PS treatment. These differences potassium fertilization source are not statistically significant. The measured parameters of fruit quality in the normal range for strawberries with an average Brix degree of 5.3, a juice acidity level of 0.35 to 0.65 % and a dry matter content of 7.8 at 9.0 %. These strawberry quality parameters were not significantly affected by potassium fertilization source. We concluded that the both sources, potassium sulfate and potassium nitrate, have equivalent effects on strawberry productivity and quality.
