The effect of the increased amounts of nitrogen on morphological and technological characteristics of malting barley

Abstract

Experiments have been conducted at the Center for Agricultural and Technological Research in Zaječar. Materials research were six genotypes of malting barley, which are fed during the growing season following quantities of nitrogen 40, 60, 80 and 100 kg ha-1. Control was the variant without recharge. The results showed that genotypes respond to increased amounts of nitrogen morphological and biological characteristics, as well as changes in technological value of seeds. Effects of nitrogen were significantly associated with distribution of rainfall during the highest water consumption.

Ogledi su postavljeni u Centru za poljoprivredna i tehnološka istraživanja u Zaječaru. Materijal istraživanja bilo je šest genotipova pivarskog ječma koji su tokom vegetacionog perioda prihranjivani sledećim količinama azota 40, 60, 80 i 100 kg ha-1. Kao kontrola poslužila je varijanta bez prihranjivanja. Dobijeni rezultati pokazali su da genotipovi reaguju na povećane količine azota promenom morfoloških i bioloških osobina, kao i promenama tehnološke vrednosti semena. Efekti upotrebljenog azota značajno zavise od rasporeda padavina u periodima najveće potrošnje vode.
