comparison of aphis fabae performance on bean plant under different fertilization regimes of n/k
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...
متن کاملStem perimeter, height and biomass of maize (Zea mays L.) grown under different N fertilization regimes in Beijing, China
In this study, nitrogen fertilizer was applied to corn (Zea mays L.) at conventional (excessive) and recommended levels, and the growth response was assessed by measuring plant height and stem perimeter. Corn plant maximum height was observed in recommended rates of N fertilizer treatment, and the height without N fertilizer was the same as that receiving excess N fertilizer. Stem perimeter was...
متن کاملEffects of cutting or grazing grass swards on herbage yield, nitrogen uptake and residual soil nitrate at different levels of N fertilization
On a Flemish sandy loam soil, cut and grazed swards were compared at different levels of mineral nitrogen (N) fertilization. Economically optimal N fertilization rates were 400 (or more) and 200 kg N ha yr on cut and grazed swards respectively. Considering the amounts of residual soil nitrate-N in autumn, these N rates also met the current Flemish legal provisions, i.e. no more than 90 kg ha ni...
متن کاملEffect of gibberellic acid on some fluorescence and chlorophyll characteristics of Cyclamen persicum Mill. seedlings under different light regimes
The use of growth regulators and light quality change are two methods to improve plant performance. Therefore, a factorial experiment was conducted in a completely randomized design. Factors included three light modes (greenhouse light (control) and LED combination light of white: red: blue as 70: 10: 20 and 40: 40: 20 ratios) and gibberellic acid in four concentrations (0, 20, 40 and 60 mg/l)....
متن کاملPhotosynthetic performance of an Arabidopsis mutant with elevated stomatal density (sdd1-1) under different light regimes.
In the Arabidopsis mutant sdd1-1, a point mutation in a single gene (SDD1) causes specific alterations in stomatal density and distribution. In comparison to the wild type (C24), abaxial surfaces of sdd1-1 rosette leaves have about 2.5-fold higher stomatal densities. This mutant was used to study the consequence of stomatal density on photosynthesis under various light regimes. The increased st...
