Abstract

In soilless culture, lack of correct management in fertigation causes stress in plants due to restricted root volume and low water holding capacity of the substrate. The present study tries to assess management of fertigation practice and Foliar application of potassium sulfate in a soilless culture of strawberry cv. paros. For this purpose, a factorial experiment has been conducted with two factors, namely fertigation frequency at three levels (1, 4, and 10 times per day) and Foliar application with potassium sulfate at three levels of concentration (0 as control, 1, and 2 g/L). The experiment has been carried out based on a complete randomized design with three replications in Vali-e-Asr University of Rafsanjan. Results show that increasing the fertigation frequency up to four times a day leads to a significant increase in dry weight of shoot and root, number of fruits, concentration of chlorophyll a and b, leaf relative water content, and leaf Ca and Mg content. The highest values of leaf area, fruit weight, number of inflorescences, as well as potassium and iron content of leaf and root have been obtained by 10 times of fertigation per day. Application of potassium sulfate foliar with a concentration of 1 g/L has had the greatest impact on leaf area as well as shoot, root, and fruit dry weight. Vegetation index has increased in plants, treated with 2 g/L potassium sulfate, compared with those without any Foliar application treatment. The highest content of leaf soluble carbohydrates belongs to the plants, treated with once-a-day fertigation and Foliar application of 2 g/L potassium sulfate.
