Accumulation and Use of Nitrogen in Durum Wheat Cultivar Predel as Influence by Fertilization
Year: 2017
Type: article
Abstract: A field study was conducted during 2012-2014 to assess the effect of nitrogen fertilization on the N concentration and uptake of durum wheat cultivar Predel. N in rates 0; 80; 120 and 160 kg ha-1 was applied. The results showed that N fertilization increased grain yield with 33.7-60.9 %. The average total dry biomass in maturity was 9.7 t ha-1. At N160P80 the dry biomass was 12.44 t ha-1. The N concentration increased with went up of N rates. At the three rates the N concentration of grain increased with 8; 27 and 45 % to the unfertilized. NP fertilization improved the N concentration. N uptake with grain was in range 52.7 - 116.8 kg ha-1, and upake with straw - 22 to 59 kg ha-1.
