<p>During 2014-2017, 22 species were identified in the yellow bowl trap type installed in winter rapeseed crops established at A.R.S.D. Secuieni. Of these, 11 species are specific to winter rapeseed crops and 11 species were accidental identified because of the proximity with different agricultural crops (maize. sunflower. grain cereals). The highest abundance was registered by <em>Epicometis hirta</em> Poda species which accounted 914 specimens collected during the analyzed period. The species were integrated into classes of dominance ((D1 - subrecedent species. D2 - recedent species. D3 - subdominant species. D4 - dominant species and D5 - eudominant species). <em>Meligethes aeneus</em> F., <em>Ceuthorrhyncus napi</em> Gyll. and <em>Epicometis hirta</em> Poda. being considered eudominant species belonging to the D5 class. The <em>Ceuthorrhynchus napi </em>Gyll.,<em> Meligethes aeneus </em>F.,<em> Epicomites hirta </em>Poda.,<em> Psylliodes chrysocephala</em> L.,<em> Subcoccinella 24 punctata L., Oulema melanopa </em>L. species were classified in the constancy class - C4 - euconstant species. <em>Meligethes aeneus</em> F., <em>Epicometis hirta </em>Poda<em> </em>and <em>Ceuthorrhynchus napi </em>Gyll. species recorded the highest values for the index of ecological significance (W %) and were classified in the W5 class - characteristic species. The collected entomofauna belongs to five orders:<em> </em><em>Coleoptera, Heteroptera, Lepidoptera,. Diptera </em>and<em> Hymenoptera. </em>The highest number of species (17 species) and the highest number of collected speciemens (3246 specimens) belonged to the <em>Coleoptera</em> order.</p>
The present paper presents the results obtained regarding the evolution of stem and fiber production in monoecious hemp, under the pedoclimatic conditions of the Center of Moldova, between 2012 and 2016. The biological material used was represented by four monoecious hemp varieties created at S.C.D.A. Secuieni, respectively, Denise, Diana, Dacia – Secuieni and Ratza. The stems yields achieved, have varied widely, ranging from 7860 kg/ha at Denise variety, in 2016 (a very warm agricultural year from the thermal point of view and rainy from the pluviometric point of view), and 15167 kg/ha, at Dacia - Secuieni in 2014 (a normal agricultural year both from the thermal and pluviometric point of view). On average, during the five years studied, the highest production of fiber was obtained in the Dacia-Secuieni variety in 2014, of 5005 kg/ha, and the lowest of 2279 kg/ha at Denise variety in 2016.
Knowledge of the particularities of the new varieties response to environmental conditions is important for the best possible territorial zoning and site stating that they need to occupy in varieties structure for each area. This paper presents research results of environmental testing of six Romanian triticale varieties at the Agricultural Research-Development Station (A.R.D.S.) Secuieni, Neamţ county, Romania, during 2007-2012 and followed the zoning of the most adapted and performing genotypes, increasing their biodiversity, so as to diminish the genetic and environmental vulnerability of agroecosystems. On average for the five years of experimentation, triticale yields achieved ranged from 6984 kg/ha (Cascador) and 8439 kg/ha (Haiduc). Of the five years of experimentation, the crop years 2008-2009 and 2010-2011 were normal in terms of rainfall, the yields achieved in these years being the highest. Depending on the average yield achieved in the five years of experimenting, the top three varieties were ranked Haiduc (8439 kg/ha), Stil (8320 kg/ha) and Plai (7961 kg/ha), the first two varieties having a very low coefficient of variability (<10). During the experiment, Romanian triticale varieties showed good resistance to winter, lodging and diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
