Abstract

Degraded and salt affected soils are appearing more often in cultivated areas. These specific problems could reduce nutrient uptake, which can result in quality and yield loss of the cultivated plants. In order to cope with this pedo-climatic condition growers are applying fertilizers; however, due to inadequate application, soil degradation will continue. Five Gladiolus varieties were subjected to foliar fertilization treatments to assess the effect on the plant’s growth parameters, vase durability and daughter corm production. Our results indicate that plants treated with foliar fertilization show significant increase in the measured parameters, flower stem length, vase durability and daughter corm production. In conclusion, our study suggests that application of foliar fertilization can increase Gladiolus plants decoration and propagation, even with a smaller footprint on nature.

Highlights

In the world 20% of the cultivated land is degraded and salt affected, which is affecting nutrient uptake and resulting in quality and yield reduction of the cultivated plants
The results of the present study indicated that a variety-specific response exists to fertilization were as follows: for ‘Green Star’, ‘Zizane’, and ‘Frizzled Coral Lace’ the highest foliar fertilization; in most cases the treatments significantly, positively influenced the percentage increase was recorded with Fitofolis (3.92%, 13.58%, and 15.54%) compared flower stem growth (Figure 2) compared to the controls
The present study provides new experimental data on the responses of five Gladiolus varieties to foliar fertilization

Summary

Introduction

In the world 20% of the cultivated land is degraded and salt affected, which is affecting nutrient uptake and resulting in quality and yield reduction of the cultivated plants. These factors are contributing to crop losses worldwide [1,2]. Foliar fertilization can be sprayed at optimum times and concentrations, according to the requirement of different plants, at different growth stages. This type of fertilization can be more suitable to the plant’s needs, in contrast to root fertilization [4,7,8]
