Influence of row spacing and sowing rate on birdsfoot trefoil (Lotus corniculatus L.) seed yield

Abstract

This paper presents the results of studying the effect of different row spacing and sowing rate on birdfoot trefoil seed yield. The case study was a local variety of birdfoot trefoil "Bokor" in agroecological conditions in nortwestern Serbia (southern part Mačve) of land pseudogley in the village Bogosavac. The data were processed statistically-variation, analysis of variance, and the significance of differences determined from the LSD test. Substantially lower yields were achieved with plants sown in wider spaced rows employing lower sowing rates. The lowest average yield of 97.1 kg / ha of seed is determined at the minimum distance between rows of 12.5 cm, while the highest average yield of 155.9 kg / ha of seeds established at a distance of 25 cm. At the largest spacing of 50 cm, the average seed yield was 155.7 kg / ha. In the variant with the highest standards using a seeding 8 kg / ha appeared the highest average seed yield of 166.33 kg / ha.

U radu su prikazani rezultati proučavanja uticaja različitog načina setve i količine semena na prinos semena žutog zvezdana. Predmet istraživanja bila je domaća sorta žutog zvezdana Bokor u agroekološkim uslovima Severozapadne Srbije (Južni deo Mačve) na zemljištu tipa pseudoglej u selu Bogosavac. Dobijeni podaci su obrađeni varijaciono-statistički, analizom varijanse, a ocena značajnosti razlika utvrđena je LSD testom. Znatno niži prinosi ostvareni su kod biljaka gajenih na većem međurednom rastojanju i manjom setvenom normom. Najveći prinos semena ostvaren je kod biljaka gajenih na međurednom rastojanju 25 cm i upotrebom 8 kg/ha semena (155,9 kg/ha). Najmanji prosečan prinos 97,1 kg/ha semena, utvrđen je na najmanjem rastojanju između redova od 12,5 cm, dok je najveći prosečan prinos 155,9 kg/ha semena ustanovljen na rastojanju od 25 cm. Na najvećem međurednom rastojanju od 50 cm, prosečan prinos semena iznosio je 155,7 kg/ha. Na varijanti sa upotrebom najveće norme setve 8 kg/ha, utvrđen je najveći prosečan prinos semena 166,33 kg/ha.
