Effect of foliar nutrition on soybean yield and quality in organic production

Abstract

Organic agricultural production recorded a continuous growth in output and demand, globally speaking, in order to meet consumer needs for quality and safe food. The plots of the Institute for Field and Vegetable Crops in Bački Petrovac, the experiment performed soybean for method in organic production, in four replications in 2011. This paper studied the influence of foliar nutrition, with microbial fertilizer on the yield and chemical composition of grain, soybean varieties in NS Galina. We studied the following properties: soybean yield (kg/ha), content (%) and yield (kg/ha) of total protein and oil content of soybeans. Have been achieved very high yields of soybean in 5,746 amounted to an average kg/ha. Yields ranged from 5,604 kg/ha in the control variant to 5,887 kg/ha for foliar feeding options. Average grain yield was higher in the variants of foliar feeding of 283 kg/ha or 5.05% compared to the control variant. Differences defined in oil content soybean material between the control and foliar nutrition were not statistically significant, while the protein content was the same in both variants. Higher protein and oil yield in the was recorded as either a foliar nutrition. Were done, the values of the correlation coefficient between the studied traits. There was a significantly high positive correlation between yield and oil content (0.73**) and a negative correlation between yield and protein content (-0.35) and between oil and protein content in soybean (-0.45). The organic production of soybean foliar nutrition proved to be a successful method for improving the yield of soybean. Research to be continued.

Organska poljoprivredna proizvodnja beleži kontinuirani rast obima proizvodnje i tražnje posmatrano u globalnim okvirima, u cilju zadovoljenja potreba potrošača za kvalitetnom i zdravstveno bezbednijom hranom. Na parcelama Instituta za ratarstvo i povrtarstvo, u Bačkom Petrovcu, izveden je ogled soje po metodama organske proizvodnje, u četiri ponavljanja, 2011. godine. U radu je proučavan uticaj folijarne ishrane sa mikrobiološkim đubrivom na prinos i hemijski sastav zrna, kod NS sorte Galina. Ispitivana su sledeća svojstva: prinos zrna soje (kg/ha), sadržaj (%) i prinos (kg/ha) ukupnih proteina i ulja u zrnu soje. Ostvareni su izuzetno visoki prinosi soje i u proseku su iznosili 5.746 kg/ha. Prinosi su varirali od 5.604 kg/ha u kontrolnoj varijanti do 5.887 kg/ha u varijanti folijarne ishrane. Prinos zrna soje u proseku bio je viši u varijanti folijarne ishrane za 283 kg/ha ili za 5,05 % u odnosu na kontrolnu varijantu. Definisane razlike sadržaja ulja u zrnu soje između kontrolnog materijala i folijarne ishrane nisu statistički značajne, dok je sadržaj proteina bio isti u obe varijante. Odrađene su vrednosti koeficijenta korelacije između ispitivanih svojstava. Zabeležena je pozitivna visoko statistički značajna korelacija između prinosa i sadržaja ulja (0,73**) i negativna korelacija između prinosa i sadržaja proteina (-0,35) kao i između sadržaja ulja i sadržaja proteina u zrnu soje (-0,45). U organskoj proizvodnji soje folijarna ishrana pokazala se kao moguć metod za poboljšanje prinosa soje. Ispitivanje treba nastaviti.
