20.500.12556/DKUM-91478 Increased planting speed did not affect silage and grain yield of maize, while saving seed and energy Optimal planting speed of vacuum maize planters is usually suggested by planter’s manufacturers, while increased planting speed may influence plant spacing and finally yield. Our hypothesis was that by increasing planting speed over the suggested level plant spacing variability will also increase which will result in decrease of silage and grain yield and saving of seed and energy. The field trial consisted of three planting speeds of 7, 9 and 11 km/h in the form of random blocks. The following measurements were taken as follows: plant spacing, silage and grain yield, fuel and energy use at planting. Results in this study show that planting speed did not have significant influence on silage and grain yield of maize, while up to 10% less seed was needed per hectare and fuel and energy use was lower for 15%. By the increase of planting speed the distance between the plants in a row, and in most cases also the plant spacing variability increased. It was noticed that by increasing planting speed plant density decreased. This research established that at higher planting speeds significant increase of the silage yield per individual plant and of the grain yield per individual plant was achieved. The ear parameters also show that the kernel mass per individual ear, the ear mass, and the cob mass, as well as the individual kernel mass, are larger at the planting speed of 11 km/h than at the planting speed of 7 km/h. At the latter planting speed, significantly higher fuel consumption per hectare and higher energy use was achieved than at the other two planting speeds. Overall the main benefits of planting speed of 11 km/h is saving seed and energy at planting while maintaning the same level of silage and grain yield compared to lower planting speeds used in the trial. energy use grain yield maize planting speed plant spacing seed savings silage yield vacuum planter hitrost sejanja pridelek koruza razmik rastlin vakumska sejalnica poraba energije prihranek semena silaža true false true Forum, PagePress Publications Angleški jezik Slovenski jezik Znanstveno delo 2025-01-07 08:51:20 2025-03-11 08:14:50 2025-03-12 03:12:41 0000-00-00 00:00:00 2020 0 0 Str. 206-213 št. 3, št. članka 1612 Letn. 15 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-03-02 2020-06-27 0000-00-00 633 21921027 10.4081/ija.2020.1612 1125-4718 Vucajnk-2020-Increased_planting_speed_did_not.pdf Vucajnk-2020-Increased_planting_speed_did_not.pdf 1 67C501A91C67BE2E7D14FFCA1164A996 dab15c386608ad248a5c4495321fb0cbcf8326ab24b1902bcd9ab445b5744b51 2befe01a-ccd5-11ef-8aab-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187639 https://doi.org/10.4081/ija.2020.1612 0 36e4d6f9-ccd5-11ef-8aab-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187640 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
