%0 Journal Article %T A preliminary study on the effect of different N and P levels on the grain yield and some yield characteristics of Amaranth (Amaranthus mantegazzianus) %A Zeynep DUMANO£¿LU %J - %D 2018 %X To evaluate the influence of different N and P levels on the productivity of amaranth, a pot experiment under outdoor condition was conducted on a amaranth genotype (cv. Don Juan) with five nitrogen (0, 50, 100, 150, 200 kg¡¤ha-1) and three phosphor levels (0, 50, 100 kg¡¤ha-1). Some traits tested in the experiment were plant height, harvest index and grain yield, crude protein content and weight of thousand grain. Results indicated that increasing N and P levels positively affected above mentioned traits compared to the control, and the highest grain yield for amaranth obtained from 100 kg P and 150 kg N application per hectare %K Horozibi£¿i %K azot ve fosfor seviyeleri %K tane verimi %U http://dergipark.org.tr/zfdergi/issue/36236/408886
