The effects of nitrogen (N) addition on productive and physiological traits of Triticumdicoccum were assessed under two N levels (0, unfertilized, and 90 kg N ha−1) in fieldconditions, in two growing seasons. In the study case, the N supply (90 kg N ha−1) was appliedin three-split applications (20% at pre-plant stage, 40% at tillering stage, 40% at stemelongation). In unfertilized conditions, t...

host plant's quality in the food chain of a herbivorous insect influences the insect's life performance, and thus abundance in its population. the effect of different ratios of n: k fertilization (40:60), (40:40), (40:0) kg/ha vs. control (0:0) were determined on chemical content parameters (n, k and c %) of the bean plant and as well on the performance of aphis fabae scop. experiment...
