Nowadays, organic fertilizers play an important role in agriculture. They are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. They provide high yield, better quality products and a shorter period of harvesting crops. In this study, the mineral elements: primary macronutrient (N, PO3- and K+), secondary macronutrient: (Ca2+, Mg...

The aim of the research was to evaluate physiological quality and early growth corn seedlings based on doses times seed soaking in biostimulant. Factorial treatments three (8, 16 24 hours) levels biostimulant (2.5, 5.0 7.5 mL L-1 water) were evaluated, plus two control that were: 1) sterile distilled water, 2) seeds without soaking. germination speed index (GSI), emergence (ESI), root length (R...

This study evaluated the effect of foliar biostimulants on fruit quality of adult 'Valencia' orange and 'Biancolilla' olive trees. Half of the selected orange and olive trees were sprayed twice before harvest with the SUNRED® commercial mix containing phenylalanine, methionine, mono-saccharides and oxylipins from plant extracts as well as potassium salts and urea. Orange and olive yields and fr...

The objective of the study was to evaluate the effect of the biostimulant Kelpak on true protein and simple sugar contents of Dactylis glomerata and Festulolium braunii at different nitrogen rates. A field experiment was set up as a randomised sub-block design (split-split-plot) with three replicates. The following factors were ha, pure-sown grass species and cultivars (monoculture). Protein co...

The study investigated the impact of biological and agricultural conditions on chemical composition energy value pea seeds for poultry feed. In experiment, species assessed was (Pisum sativum L.), a determinate form, cultivar (cv.) Cysterski. During field response peas to following experimental factors assessed: first factor—irrigation (yes, no), second factor—nitrogen fertilization (0, 20 40 k...

ABSTRACT Biostimulants currently available on the market include those containing seaweed extract. There is sufficient scientific evidence to conclude that applying biostimulants agricultural crops can positively impact plant growth and yield. However, results differ between plants species environmental conditions. As such, present study aimed assess effects of doses application times a biostim...
