Special Issue Information

Dear Colleagues,

Plant growth and development is largely determined by nutrient availability in soil. Thus, to ensure better crop productivity and quality, it is essential to understand the dynamics of nutrient uptake, interactions, factors affecting their availability, etc. Crop plants are frequently subjected to nutrient imbalance, which adversely affects several metabolic processes and, in turn, crop yields. Balanced fertilization, recycling of crop residues, agronomic biofortification, application of micronutrients in soil, biofertilizers, etc. offer good solutions to overcome nutrient deficiency. The increasing deficiency of nutrients, especially micronutrients, is being reported in several parts of the world; high-yielding crop varieties, the sole application of straight fertilizers, the non-addition of organic manures, imbalanced fertilization, etc. are a few reasons for deficiencies. Nutrient deficiencies are emerging as an obstacle in the way of sustainable crop production. Inadequate consumption of any one of the essential nutrients limits plant growth owing to adverse metabolic disturbances, leading to reduced yield and quality, even when all other nutrients are present in adequate amounts. Keeping in view the specific role of each nutrient in plants, it is very essential to manage them accordingly in soil to ensure better soil health and sustainable crop production. Hence, this Special Issue on ‘The Role of Macro and Micronutrient in Plant Growth and Development’ is a timely effort.

The aim of the paper is to assess the impact of Foliar Fertilizations (FF) on the yield and quality of sunflower seeds. This research was carried out in the agricultural years of 2019–2021 in the experimental field of the university. The method of planting in the field was carried out in subdivided plots with three repetitions and six fertilization options. The experimental variants were as follows: Control (Mt), V1—FF 10:10:10+ME (microelements), V2—FF 8:10:0+8B (Boron)+ME, V3—FF 15:0:0+2S (Sulfur)+1B+ME, V4—FF 15:0:0+4B+ME, and V5—FF 8:8:8+ME. FF treatments were carried out in the vegetation phases specific to the sunflower crop. These varied from 2–6 L ha−1, depending on the chemical composition of the product. The application of treatments with FF to the sunflower culture positively influenced both production and its quality expressed by specific quality indices, namely the content of proteins, lipids, carbohydrates, fibers, and minerals. The results were discussed not only in view of classical statistics but also using the Principal Components Analysis (PCA), which allows a more complex evaluation of the effects of foliar treatments on the production and quality of sunflower seeds.
