The effect of N fertilization on share of alfalfa leaf and protein content in grass-leguminous mixtures
Uticaj đubrenja N na udeo lista lucerke i sadržaj proteina u travnoleguminoznim smešama
Abstract
Different ratio of plant organs means that their role and contribution to forming of total yield and quality is different. Objective of this research was to monitor changes in the share of alfalfa leaf in mixtures depending on the type of mixture and N fertilization. Trial was set in the period 2003-2004 as twofactorial trial according to method of random block system in four repetitions. Research included three mixtures: alfalfa+cocksfoot (Medicago sativa + Dactylis glomerata); alfalfa+cocksfoot+tall fescue (Medicago sativa + Dactylis glomerata+Festuca arundinaceace); alfalfa+cocksfoot+tall fescue +sainfoin Medicago sativa + Dactylis glomerata+ Festuca arundinaceace+Onobrychis sativa) and pure alfalfa (Medicago sativa) crop as control variant, as well as four fertilization variants 0, 70, 140 and 210 kg N ha-1. Statistically highly significant differences in the effect of both investigated factors on the share of alfalfa leaf were established only in the first investigation year. The ...lowest share of leaf was determined in pure alfalfa crop 53.7%, whereas the mixture II had the highest share of leaf of 58.2%. The greatest share of leaf was established in treatments with 210 kg ha-1 - 58.0%, and the lowest share of alfalfa leaf in total yield was determined in treatments without N - 53.3%.
Različit odnos biljnih organa znači da je njihova uloga i doprinos u formiranju ukupnog prinosa i kvaliteta različita. Cilj ovih istraživanja je bio da se prate promene u udelu lista lucerke u smesama u zavisnosti od vrste smese i đubrenja N. Ogled je postavljen u periodu 2003-2004. god. kao dvofaktorijalni ogled po metodi slučajnog blok rasporeda u četiri ponavljanja. Istraživanjima su obuhvaćene tri smeše: lucerka+ježevica (I); lucerka+ježevica+visoki vijuk (II); lucerka+ježevica+visoki vijuk+esparzeta (III) i čist usev lucerke, kao i četiri varijante đubrenja 0, 70, 140, 210 kg N ha-1. Ispitivanjima su utvrđene statistički visoko značajne razlike u uticaju oba ispitivana faktora na udeo lista lucerke kao i visoko značajan uticaj đubrenja N na sadržaj SP samo u 2003 godini.
