Partial factor productivity of nitrogen fertilizer on grain and grain protein yield of durum wheat cultivars
Abstract. This study was conducted at the Field Crops Institute in Chirpan, Bulgaria, on Pellic vertisols soil type under non-irrigated conditions in the period of 2011 –2013. Tests were made on the effect of nitrogen fertilization at rates of 0; 60; 120 and 180 kgN/ha on seven durum wheat cultivar...

| description | Abstract. This study was conducted at the Field Crops Institute in Chirpan, Bulgaria, on Pellic vertisols soil type under non-irrigated conditions in the period of
2011 –2013. Tests were made on the effect of nitrogen fertilization at rates of 0; 60; 120 and 180 kgN/ha on seven durum wheat cultivars. The cultivar response
was studied regarding the yield produced out of a unit of applied nutrient. It was found that the partial nitrogen productivity of grain and protein decreased by
increasing the applied amounts of nitrogen fertilizer into the soil. The rate of N yielded the highest average partial productivity of nitrogen (69.8 kg/kg). The 60
Elbrus and Deana cultivars had the highest partial nitrogen productivity of grain (47 –50 kg N/kg). The Elbrus cultivar manifested a tendency for the highest
efficiency in forming the grain protein yield (7.2 kg N/kg) out of a unit of applied nitrogen fertilizer. The partial nitrogen productivity increased in favourable
temperature and moisture weather conditions during wheat vegetation. |
