Effects of the sowing density on the yield and the number of germinated seeds in seed maize
Uticaj gustine setve na prinos i broj klijavih zrna u semenskom kukuruzu
Abstract
The trials were carried out in the regular production of the seed maize ZP 680 at the agricultural estate "Nova Budućnost" Žarkovac during 2001 and 2002. Sowing densities (71,400, 85,500, 99,900 plants ha"1) affected varying of yields (4.01, 4.38. 4.40 t ha"1). The 1000-seed weight decreased over increased densities (305.6, 2912, 282.5 g). Germination was even over densities (95.0, 94.9, 94.7 %). A greater number of germinated seeds per area unit (13,122,000, 15,022,000, 15,569,000) was obtained in greater densities. The percentile share of fractions in the weight was uniform over all sowing densities.
Ogledi su izvedeni u PD "Nova Budućnost" Žarkovac 2001 i 2002. godine u prirodnim uslovima gajenja semenskog kukuruza ZP 680. Gustine setve (714.00, 85.500, 99.9.00 bilj/ha) su uticale na variranje prinosa (4.01, 4.38. 4.40 t/ha). Masa 1000 semena opadala je sa povećanjem gustine (305.6, 2912, 282.5 g). Klijavost je bila ujednačena po gustinama (95.0, 94.9, 94.7 %). U većim gustinama dobijen je veći broj klijavih semena po jedinici površine (13.122.000, 15.022.000, 15.569.000). U sve tri gustine procentualno učešće frakcija u masi bilo je ujednačeno.
