Abstract
The study examined the effects of seed inoculation, NPK fertilization, and nitrogen fertilization on yield components and bean seed yields of Galeb cultivar. Microexperiments in the field were performed during 2019 in the agroecological conditions of central Šumadija (locality Rača Kragujevačka), on brown forest soil type (Eutric Cambisol). The research included a two-factor factorial design of the following variants: a) fertilization: 1) Control (unfertilized), 2) NPK 6:24:12 (400 kg ha-1 a.m.), 3) AN 34% N (200 kg ha-1 a.m.), 4) NPK 6:24:12 (400 kg ha-1 a.m.) + AN 34% N (200 kg ha-1 a.m.), b) seed inoculation: 1) without inoculation and 2) with inoculation. The applied agro-technique was a standard one, i.e. identical to the regular beans production. The research showed that increased nutrition, regarding the yield’s components, increased the number of pods per plant from od 26.5% (variant AN) to 52.9% (applied variant NPK+AN), along with the number of seeds per plant increasing from 11.0% (AN) to 28.0% (NPK+AN), as well as the mass of the seed per plant from 31.0% (AN) to 75.9% (NPK+AN). During the fertilization process, bean seed inoculation caused the number of pods per plant to decrease by 2.2%, the number of seeds per plant decreased by 1.6% while the plant seed’s mass reduced by 4.7%. Additional fertilization in the form of nitrogen fertilization only (AN) increased the bean seed yields by 9.3%, while NPK fertilization at the beginning increased it by 31.3%. Also, the number of seeds in NPK+AN variant was increased by 22.9%. As for the variant without fertilization, seed inoculation enabled a higher yield by 70 kg ha-1 compared to the treatment without inoculation. The highest bean seed yield (1.96 t ha-1) was obtained with the combination of NPK fertilizer at the start and seed inoculation caused by nodule bacteria.
