abstract = "Razvoj nauke i tehnologije dovodi do stvaranja novih pristupa u oplemenjivanju useva i različitih metoda za podsticanje povećanja produktivnosti viših biljaka. Jedna od najnovijih metoda je implementacija ekološki prihvatljive tehnike korišćenja pulsirajućeg elektromagnetnog polja niskih frekvencija (PEMP). U radu su prikazani rezultati uticaja elektromagnetne stimulacije semena soje na broj zrna po biljci, masu 1000 zrna i prinos zrna u različitim agroekološkim uslovima. Soja zauzima važno mesto u pogledu ishrane ljudi i životinja, jer seme soje obiluje bogatim sadržajem ulja, proteina i masti. U trogodišnjem istraživanju u periodu od 2013-2015 korišćena je sorta soje Valjevka, gajena pri različitim količinama organskog granuliranog živinskog đubriva formulacije 4:4:4 (kontrola – bez đubrenja, 750 kg.ha-1 i 1300 kg.ha-1). Pre setve, seme je bilo podvrgnuto stimulaciji elektromagnetnog polja niskih frekvencija (PEMP) u sledećim konfiguracijama: kontrola - bez stimulacije i stimulacija naizmeničnim magnetnim poljem (PEMP) sa indukcijom od 30 mT i vreme ekspozicije od 15 min. Utvrđeno je da je varijabilnost ispitivanih parametara zavisila od sva tri faktora i to na statistički značajnom nivou od 1%. Istovremeno, vrednosti ispitivanih parametara je bila najveća u 2014. godini uzgoja u odnosu na 2013. i 2015. godinu (izuzev mase zrna po biljci koja je bila najveća u 2013) pri đubrenju od 1300 kg.ha-1 i stimulaciji semena sa PEMP. Prosečan broj zrna pri stimulaciji semena bio je za 32,64% (77,82) viši nego bez PEMP (58,67). Masa 1000 zrna sa PEMP je iznosila 155,99 g, što je bilo više za 2,06% u odnosu na varijantu bez PEMP (152,83 g). Prosečan prinos zrna soje za sve tri godine istraživanja sa stimulacijom semena je bio 4,85% (3481,25 kg.ha-1) viši nego bez PEMP (3320,14 kg.ha-1). Stimulacija semana sa PEMP ima ekonomsku opravdanost, obzirom na rast cena soje na svetskoj berzi. Rezultati sugerišu da PEMP tretman semena soje ima potencijal u kvalitetnoj, bezbednoj i visoko rodnoj proizvodnji i da se suprotstavi neželjenim efektima poput suše i nedostatka đubriva., The development of science and technology leads to the creation of new approaches in crop breeding and various methods to encourage increased plant productivity. One of the latest methods is the implementation of an environmentally acceptable technique of using a pulsed low frequency electromagnetic field (PEMP). The paper presents the results of the influence of electromagnetic stimulation of soybean seeds on the number of grains per plant, weight of 1000 grains and grain yield in different agroecological conditions. Soybeans occupy an important place in terms of human and animal nutrition, because soybean seeds are rich in oil, protein and fat. In a three-year study in the period from 2013-2015, the soybean variety Valjevka was used, grown with different amounts of organic granular poultry fertilizer formulation 4: 4: 4 (control - without fertilization, 750 kg.ha-1 i 1300 kg.ha-1). Before sowing, the seeds have been subjected to the stimulation of low frequency electromagnetic field (PEMF) in the following configurations: control - without stimulation and stimulation alternating magnetic field (PEMF) with the induction of 30 mT and exposure time of 15 min. It was found that the variability of the examined parameters depended on all three factors at a statistically significant level of 1%. At the same time, the values of the examined parameters were the highest in 2014 in relation to 2013 and 2015 (except for the mass of grain per plant, which was the highest in 2013) during fertilization of 1300 kg.ha-1 and stimulation of seeds with PEMP. The average number of grains during seed stimulation was 32.64% (77.82) higher than without PEMP (58.67). The weight of 1000 grains with PEMP was 155.99 g, which was 2.06% more than the variant without PEMP (152.83 g). The average yield of soybean grain for all three years of research with seed stimulation was 4.85% (3481.25 kg.ha- 1) higher than without PEMP (3320,14 kg.ha-1). Stimulation of seeds with PEMP has economic justification, given the growth of soybean prices on the world stock market. The results suggest that PEMP treatment of soybean seeds has the potential in quality, safe and high-yield production and to counteract the adverse effects such as drought and the lack of fertilizer.",
