چکیده

Increasing population growth has led to more food needs. Mineral nutrition management of plants is a key factor in determining the quantity and quality of leafy vegetables. Optimizing the concentration of nutrients is essential in order to obtain the maximum yield and quality of these products. Today, commercial food solutions and different standards are recommended for plant nutrition under water conditions. However, due to various nutritional needs of different herbs, different stages of plant growth and diversity in atmospheric conditions of different places, it is not possible to introduce a nutrient solution for a plant. This research was carried out with the aim of investigating the effect of X Ferrule and Hoagland solutions on quantitative and qualitative characteristics of two lettuce varieties (Lactuca sativa) in non-soil cultivation. This research was carried out as a factorial experiment in a completely randomized design with three replications in a pot. Varieties containing Ferdows and Taftan and dietary solutions containing X Ferrule solution with concentrations of 1.10, 1.20, 1.30, 1.40, 1.50 and 1.80, the X Ferrule were also enriched in concentrations of 1/10, 20/1, 30/1, 40/1, 50/1 and 80/1, and alternate feeding that's mean it was done one time with a solution of X Ferrule with concentrations of 1.10, 1.20, 1.30, 1.40, 1.50, 1.80 and another time with Hoagland solution 1.4. The seeds of these cultivars were cultivated separately and after 45 days the seedlings were transferred to the main pots. Ten days after culturing, nutrition began with the above mentioned solutions. After 60 days, the traits were evaluated. Evaluation of the results of variance analysis of the simple effect of nutrient solution on fresh and dry weight of shoot and root, bush height, potassium and chlorophyll index at 1% probability level and on the diameter of the crown, nitrogen and phosphorus at a 5% probability level and simple effect of cultivar on plant height, root volume
