dc.description.abstract | Sweet maize, a popular vegetable, occupies an important place in the population's diet, and in
recent decades, the area under this crop has been increasing. In this paper, the influence of
cover crops (CC), with and without the application of microbiological fertilizer, on the yield
and yield components of sweet maize (hyrbid ZPSC 421su, FAO 400) was examined. The
experiment was carried out at the "Zemun Polje" Maize Research Institute during 2014/15-
2015/16. CC consisted of four types of plants: 2 legumes: T1-common vetch, T2-field pea, 2
non-leguminous species: T3-winter oats and T4-fodder kale. Two variants with mixtures
were: T5-common vetch + winter oats and T6-field pea + winter oats and two controls T7
(straw) and T8 (bare soil). CC was sown in autumn, plowed at the end of April or May, after
which 1/2 of the plot was treated with microbiological fertilizer. Sweet maize was sown in
mid-May at a density of 65,000 plants per ha. For industrial processing, the shape, size and
uniformity of the corn cob, grain size, and row configuration are important. CC influenced the
increase in the number of grain rows and the number of grains in a row, the most in the
variant T4, and the weakest in the variants with mixtures (T5 and T6). The highest cob length
values were measured in the T4 variant. The largest cob diameter was measured in 2016 in T4
(4.6 cm), and the smallest value in controls (3.1 cm and 3.3 cm) in 2015. By comparing the
examined years, we can see that in the first year the highest yield was achieved in the T4
variant (6261.70 kg ha-1), while the lowest was achieved in the T6 variant (2732.88 kg ha-1) in
the second year. | sr |
