Influence of mineral nutrients on the number of leaves and root weight of sugar beet

Abstract

Šećerna repa je važna industrijsku i prehrambenu sirovina. Rezerve ulja semena šećerne repe igraju važnu ulogu u uspešnom klijanju i razvoju rasada. Proizvodne površine su ograničene a kod proizvodnje šećerne repe važno je poštovati pravila plodoreda pa se postizanje povećanja prinosa korena vrši raznim agrotehničkim merama među kojima važnu ulogu ima i primena hraniva. Na oglednim poljima PSS Instituta Tamiš tokom tri godine, izvedena su ispitivanja sa tri sorte šećerne repe. Ispitivan je uticaj različitih količina NPK hraniva na broj listova i težinu korena. Najveća brojnost listova kao i najveća težina korena zabeležena je kod sorte Otis. Promena rastućih količina NPK hraniva u malom procentu je uticala na brojnost listova kod sorti ali je značajno uticala na prosečnu težinu korenva, povećanje je u nekim slučajevima iznosilo skoro 50%.Sugar beet is an important industrial and food raw material. Sugar beet seed oil reserves play an important role in successful germination and seedling development. Production areas are limited, and in the production of sugar beet, it is important to follow the rules of crop rotation, so achieving this increase is done by various agrotechnical measures, among which the application of nutrients plays an important role. On the experimental fields of PSS Institute Tamiš, tests were carried out on three varieties of sugar beet during three years. The influence of different amounts of NPK nutrients on the number of leaves and the weight of the roots was examined. In these experiments, the highest number of leaves as well as the highest weight of the roots was recorded in the variety Otis. The change in the growing amounts of NPK nutrients affected the number of leaves in the varieties by a small percentage but significantly affected the average weight of the roots, the increase in some cases was almost 50
