Effect of Potassium Iodide and Salicylic Acid in the Cultivation of Hydroponic Strawberries (Fragaria L)

Abstract

The fortification of essential foods that the majority of the population consumes has a very great advantage in nutrition; Since it is one of the most effective ways to fill some deficiencies, the objective of this work is to increase the nutritional value of strawberry cultivation under hydroponic conditions, the methodology started with the disinfection with 10% chlorine of the hydroponic system, it was located In the basket, to place the seedlings, the nutrition was implemented with the initial Steiner's solution at 50% and later at 100%, three salicylic acid (AS) treatments were carried out: 0.0012 g / L, 0.0030 g / L, 0.0070 g / L and control (0 salicylic acid) and Potassium Iodide (KI) with treatments of 0.0014g / L, 0.0016g / L and 0.0018g / L and control (0 iodine). In soluble solids, a total of three fruits were selected per treatment, it was shown that (T3), repetition 1 (0.0014 g / L) with KI, obtained an average of 8 fruits, the (T1), repetition 2 (0.0030 g / L) with AS (Salicylic Acid) with an average of 23.3 g of fruit weight, repetition 1 (0.0014 g / L) with IK, obtained an average of 8.8000 ºBrix, the ANOVA analysis shows in AS a P value of 0.034, in the control has a P value of 0.054 and in IK a P value of 0.040, which tells us that there is a positive significance in relation to the control towards the weight of the fruits, for which treatment number three is suggested for subsequent work .
