Uticaj rokova setve na prinos, ukupnu klijavost i masu 100 semena piskavice (Trigonella foenum graecum L.)
Effects of sowing dates on the yield, total germination and 100-seed weight of fenugreek (Trigonella foenum greacum L.)

Sažetak
Ispitivan je uticaj rokova setve domaće sorte piskavice na prinos, ukupnu klijavost i masu 100 semena. Ogled je postavljen u Pančevu 2007 i 2008 godine po metodu slučajnog blok sistema sa četiri ponavljanja. Setva je obavljena u osam rokova: I (07.03), II (17.03), III (27.03), IV (07.04), V (17.04), VI (27.04), VII (07.05) i VIII (17.05.) Požnjeveno seme dosušeno je do 9% vlage, očišćeno od primesa, a nakon toga je izmeren prinos. Iz svakog ponavljanja uzeti su uzorci semena za ispitivanje ukupne klijavosti i mase 100 semena. Naklijavanje semena vršeno je u klijalištu semenske laboratorije Instituta za proučavanje lekovitog bilja 'Dr Josif Pančić' u skladu sa ISTA standardima. Na osnovu analize varijanse utvrđeno je da rokovi setve veoma značajno utiču na sve ispitivane osobine. Faktor godine bio je veoma značajan za prinos i ukupnu klijavost semena, dok za osobinu masa 100 semena nije bilo značajnog uticaja. Interakcija rokova setve i ispitivanih godina bila je veoma značajna za ukupnu klijavost, a za prinos i masu 100 semena nisu utvrđene značajne razlike. Najveći prinos semena ostvaren je u V i IV roku setve i LSD testom utvrđena je značajna razlika u odnosu na ostale rokove setve. Seme iz četvrtog roka setve (07.04) imalo je najveću klijavost i masu 100 semena. Na osnovu dvogodišnjih rezultata utvrđeno je da je optimalni rok za setvu piskavice u lokaciji Pančevo od 07.04. do 17.04 (IV i V rok).
Abstract
The effects of eight sowing dates of the domestic cultivar fenugreek on the yield, total germination and 100-seed weight were observed in the present study. The four-replicate trial was set up according to a randomised block design in Pančevo in 2007 and 2008. Sowing was done on eight dates: I (March 7), II (March 17), III (March 27), IV (April 7), V (April 17), VI (April 27), VII (May 7) and VIII (May 17). Harvested seed was dry down to 9% moisture, cleaned off all admixtures and then the yield was determined. Seed samples were drawn from each replicate for testing total germination and the100-seed weight. Seeds were germinated according to the ISTA Rules in a germination cabinet at the Institute for Medicinal Plant Research 'Dr Josif Pančić'. According to the analysis of variance, all sowing dates very significantly affected all studied traits. The factor year was very important for the yield and total seed germination, while there were no significant effects on the 100-seed weight. The sowing date x year interaction was very important for total germination, while there were no significant differences in yields and 100-seed weights. The highest yield was obtained on the V and IV sowing dates, while the performed LSD test showed significant difference in relation to other sowing dates. The greatest germination and 100-seed weight were recorded in the seed of the fourth sowing date (April 7). Based on the two-year results, it can be concluded that the optimum dates for fenugreek sowing in the location of Pančevo range from April 7 to April 17 (i.e. IV and V sowing dates).
