INFLUENCE OF SUGARBEET SEED TREATMAN AND SOWING DISTANCE IN A ROW ON FIELD GERMINATION AND SUGARBEET

U radu se iznose rezultati istraživanja utjecaja načina dorade sjemena i razmaka sjetve u redu na poljsku klijavost i sklop šećerne repe. lstraživanja su provedena u Podravini (Kalinovac) u trajanju od dvije godine. lspitivan je način dorade sjemena (pilirano, polirano i inkrustirano) i razmak sjetve unutar reda (6, 12 i 18 cm). Varijante sijane na 6 i 12 cm nakon nicanja su prorjeđivane, kod varijanti na 6 cm ostavljena je svaka treća biljka a kod varijanti na 12 cm svaka druga biljka. Razmak između redova je iznosio 50 cm. Usporedujući različite načine dorade sjemena, (pilirano, polirano i inkrustirano) signifikantno opravdan utjecaj na poljsku klijavost i sklop nije dao prednost ni jednoj varijanti, iako se neznatno boljom pokazala poljska klijavost inkrustiranog sjemena. Povoljne vremenske prilike u vrijeme sjetve u drugoj godini pokusa dovele su do općenito viših vrijednosti poljske klijavosti, ali također ne ističući ni jedan način dorade sjemena. Uspoređujući utjecaj razmaka sjetve unutar reda ni u jednoj godini pokusa nije bilo opravdanih razlika između tri ispitivana razmaka na poljsku klijavost. No, signifikantno opravdane razlike su dobivene u broju biljaka nakon sjetve a prije vađenja , posebice u korist sjetve na 6 cm, zatim na 12 cm a najmanje vrijednosti sklopa su dobivene sjetvom na 18 cm bez prorjeđivanja.The influence of sugarbeet seed treatment and sowing distance in a row on field germination and sugarbeet stand were investigated. The trials were carried out in Podravina in a two years period. Three ways of seed treatment (polished, pelleted and incrusted seed) and three sowing distances (6, 12 and 18 cm) were investigated. After germination, a variant sown at 6 cm distance was thinned out at 18 cm and another variant sown at 12 cm was thinned out at 24 cm. Distance between the rows was 50 cm. The results showed that no variant of seed processing had significant influence on sugarbeet stand and field germination. Only insignificant higher field germination was with incrusted seed. Favourable weather conditions in the second year of trial, at the time of sowing brought to higher field germination for all seed processing variants. Also different variants of sowing distance showed no significant influence on field germination. However, significantly highest sugarbeet stand was at 6 cm of sowing distance and the lowest stand was at 18 cm of sowing distance without thinning
