Testiranje sejalice za setvu širokorednih useva AMAZONE EDX 6000-TC
Testing of planter AMAZONE EDX 6000-TC
Projekat: Unapređenje kvaliteta traktora i mobilnih sistema u cilju povećanja konkurentnosti, očuvanja zemljišta i životne sredine (MPNTR - 31046)
Sažetak
Setveni agregat je jedan od najbitnijih faktora u celokupnoj proizvodnji ratarskih kultura. Njegov značaj se ogleda kako u kvalitetu setve tako i sa ekonomskog aspekta u vidu brzine setve. Parametri rada ovog sistema su pokazatelji kvaliteta rada velikog dela ukupne proizvodnje. Stoga se ovim parametrima mora pokloniti puno pažnje. Količina isejanog semena u redu i razmak između semena su bitni faktori u proizvodnji što ima uticaj na ujednačen rast i razvoj biljaka i stabilan prinos. Ovi parametri zavise od eksploatacionih mogućnosti setvene jedinice sejalice. Aritmetička sredina razmaka (Ks), standardna devijacija razmaka između biljaka (SD) i koeficijent varijacije (CV), obično se koriste za opisivanje uniformnosti setve. Aritmetička sredina razmaka zavisi od semena ili gustina biljaka i uzdužne raspodele. U radu su prikazani podaci dobijeni ispitivanjem sejalice AMAZONE EDX 6000-TC T testom za nezavisne uzorke, testom homogenosti varijanse, Dankanovim testom i LSD testom.
Abstract
The sowing unit is one of the most important factors in the overall crop production. Its importance is reflected both in the quality of sowing and from the economic point of view in the form of sowing speed. The operating parameters of this system are indicators of the quality of work of a large part of the total production. Therefore, a lot of attention has to be paid to these parameters. The amount of seed sown in the row and the distance between the seeds are important factors in production which has an impact on the uniform growth and development of the plants and a stable yield. These parameters depend on the operating capabilities of the sowing unit of the planter. Arithmetic mean spacing (Ks), standard deviation of plant spacing (SD) and coefficient of variation (CV), are commonly used to describe the uniformity of sowing. The arithmetic mean of the spacing depends on the seed or plant densities and longitudinal distribution. This paper presents data obtained by testing the AMAZONE EDX 6000-TC T seeder for the independent specimen test, the homogeneity test for variance, the Duncan test and the LSD test.
