“…Maximum role in population fluctuation of whitefly was played by nitrogen (80.62 %). Aphids: Host plant quality is known to be an important fac-tor affecting aphid demography, survival, fecundity and life expectancy (Dixon 1987;Rostami et al, 2012). Fertilization also influences the distribution and population dynamics of aphid pests seriously (Tan et al, 2012).…”

Nutrition of plants has a substantial impact on the predisposition of plants to insect-pests. Regulated and balanced crop fertilization can be helpful in altering host plant susceptibility to sucking insect-pests. Hemipteran herbivores are sensitive to alteration in host plant nutrition. Primary pest defence of plants like biochemical, physical and mechanical properties can be enhanced by balanced fertilization with plant nutrients. All plant nutrients may affect plant health but two of them namely, nitrogen and potassium play a major role. The effect of other nutrients is less frequently mentioned. Most studies revealed that generally excessive use of nitrogen decreases crop resistance to pests whereas potassium increases the same. So, the agricultural practices like excessive, injudicious and unscientific use of fertilizers can result in nutrient imbalance and finally into increased attack of insect-pests. Careful consideration of present and future information on this topic can lead to better predictive capabilities in hemipteran insect-pest management.

“…The current trends in the chrysanthemum industry are focused on improving flower quality and creating environmentally-friendly production systems [4,5]. To achieve these goals and accelerate chrysanthemum production, further innovation is needed in improving fertilization regimes and other production techniques [6,7]. In many areas of the world, especially in China, chrysanthemum plants are cultivated under greenhouse conditions, and the over-application of chemical fertilizers has influenced the soil quality and caused serious environmental problems [8,9].…”

Abstract:Organic fertilizers are generally thought to be an effective way to sustain soil fertility and plant growth. To promote the productivity of chrysanthemum, five sources of liquid organic fertilizers (L1-L5), as well as a chemical fertilizer, were applied at an early stage of the growth cycle to investigate their effects on plant growth. In the short-term pot experiment, the liquid organic fertilizers significantly promoted root and aboveground growth by 10.2-77.8% and 10.7-33.3%, respectively, compared with the chemical fertilizer. The order of growth promotion was: L1 (shrimp extracts) > L2 (plant decomposition) > L4 (seaweed extracts)/L5 (fish extracts) > L3 (vermicompost). Morphological and chemical analyses indicated that, compared with other organic fertilizers, the treatment with shrimp extract (L1) produced the greatest increases in root dry weight, total length, surface area, volume, tips, and thick root length, respectively. Furthermore, the shrimp extract treatment significantly increased the nutrient contents and altered the soil's functional microbial community at the rhizospheric level compared with the chemical fertilizer treatment. Thus, the shrimp extract liquid organic fertilizer could be part of an effective alternative to chemical fertilization during the early stage of chrysanthemum growth.

“…For both experiments, the jackknifing technique was employed to estimate means and 95% CI (confidence interval) for all life table parameters. This technique is done by repeated calculation of the parameter estimates by excluding 1 sample in turn as described by Meyer et al (1986), and used in the studies of Maia et al (2000), Zamani et al (2006), Hosseini et al (2010), Rostami et al (2012), and Eini et al (2017).…”
