Spelt grain yield (triticum aestivum ssp spelta) depending on growing localities

Abstract

The paper examined the impact of growing localities on grain yield spelt (Triticum aestivum spp. spelta). The first location was a “Radmilovac” experimentally well-Faculty of Agriculture in Zemun on leached chernozem soil type, and second region is the mountains Zlatar, in mountainous conditions at over 1.000 m above sea level. In both localities research was conducted as to examine the effects of different microbiological fertilizers (Slavol) on spelt grain yield in organic farming systems. Microbiological fertilizer (Slavol) was applied in top-dressing at both locations. In the first locality in the fall, we used organic fertilizer (Ofert Royal) and in the second locality used microbiological fertilizer Uniker alone and in combination with soil additives (hydrogel and zeolite). In the first location (Radmilovac) gave the grain yield of 4.80 t ha-1 (2010/11) and 5.07 t ha-1 (2011/2012) on the control 4. 35 t ha-1 and the variant with top dressing 5.60 t ha-1. Applying the statistical analysis of data on grain yield in second locality, it was found that the greatest difference in yield was recorded between the investigation years: 4.60 t ha-1 (2010/11) and 2.82 t ha-1 (2011/12). When applying top dressing some differences were recorded, but they were not statistically significant (3.66 t ha-1 : 3.76 t ha-1).

U ovom radu ispituje se značaj lokaliteta gajenja na prinos zrna alternativne vrste pšenice-krupnika (Triticum aestivum spp. spelta). Prvi lokalitet je eksperimentalno ogledno dobro Poljoprivrednog fakulteta “Radmilovac”. Usev je gajen na zemljištu tipa izluženi černozem. Drugi lokalitet je selo Radijevići, opština Nova Varoš-lokalitet Zlatara, nadmorska visina preko 1000 m. Ispitivan je uticaj različitih mikrobioloških i organskih đubriva i oplemenjivača zemljišta na prinos zrna krupnika u organskom sistemu gajenja. Mikrobiološko đubrivo (Slavol) je primenjeno u prihranjivanju u oba lokaliteta. U prvom lokalitetu, u jesen smo primenili organsko đubrivo (Ofert Royal) a na drugom lokalitetu mikrobiološko đubrivo Uniker samostalno ili u kombinaciji sa oplemenjivačima zemljišta (hidrogel i zeolit). Dobijeni prinosi zrna su bili veći u prvom lokalitetu, posebno u varijantama sa prihranjivanjem (5,60 t ha-1), u odnosu na kontrolnu varijantu (4,35 t ha-1). Posmatrano po godinama istraživanja, veći prinosi su dobijeni 2011/12 (5,07 t ha-1) a u 2010/11 (4,80 t ha-1). Na osnovu statističke analize dobijenih rezultata u drugom lokalitetu, ustanovljeno je da su najveće razlike u prinosu zrna između ispitivanih godina: 4,60 t ha-1 (2010/11) a 2,82 t ha-1 (2011/12). Takođe, postoje i razlike u varijantama sa prihranjivanjem (3,76 t ha-1) u odnosu na kontrolu (3,66 t ha-1), ali one nisu statistički značajne.
