Research regarding the behaviour of some perennial grasses and legumes mixtures in order to establish temporary grassland exploited in meadow regime

In making perennial grasses and legume mixtures is envisaged that the species or varieties used to properly reflect the stationary conditions, the annual climatic variations sometimes influence different the components behavior, and therefore the productivity. The researches were conducted during 2013-2015 in the Agricultural Research - Development Station Secuieni, where was followed the influence of four nitrogen doses on a phosphorus agrofond in an experience of five mixtures of perennial grasses and legumes used in meadow regime. The nitrogen fertilizers are used in smaller doses in mixtures, because this element is provided by symbiotic bacteria living on the roots of legumes. The results showed that the dynamic of biomass accumulation was done in three growth cycles, for the first cycle it took 53 days, for the second cycle 42 days and for the third cycle 52 days. The highest production of 24.03 t/ha dry substance it was recorded at Festuca arundinacea 30% + Dactylis glomerata 20% + Festuca pratensis 20% + Medicago sativa 20% + Trifolium pratense 10% mixture and fertilized with N80+40P40 dose, and the lowest of 14.59 t/ha d.s. was obtained at Dactylis glomerata 30% + Lolium perene 40% + Medicago sativa 20% + Lotus corniculatus 10% mixture in the unfertilized variant

Researches regarding the influence of distance between rows on the stem and fiber yields at some monoecious hemp varieties under the center of Moldavia pedoclimatic conditions

Hemp is part of the textile plants group with high-value for human and industrial use. Hemp has over 25,000 uses, ranging from food, paints and fuels to clothing and building materials. Hemp is currently considered to be a plant of increasing importance for Europe, being used for fiber and oil extraction and as medicinal plant. Hemp fibers are the most resistant plant fibers and as such, in the past, they were the most prized raw material of the textile industry worldwide.In this paper we present the results regarding the evolution of monoecious hemp crop on the production of stems and fiber, under the pedoclimatic conditions of the Center of Moldova, between 2012 – 2015. The biological material used was represented by three varieties created at A.R.D.S. Secuieni, respectively, Denise, Diana and Dacia and were sown at a distance of 12.5 cm, 25 cm respectively 50 cm between rows. The obtained results revealed that the studied factors influenced to a great extent the production of stems, which varied widely, ranging from 8113 kg / ha to the Denise variety at a distance of 12.5 cm in 2015 (agricultural year characterized as very dry from pluviometric point of view), and the highest yields were obtained at the Denise variety of 15683 kg / ha, at a distance of 25 cm in 2013 (agricultural year characterized as normal from rainfall point of view). On average, for the four years studied, the highest obtained production of fiber was achieved by Dacia variety, at 12.5 cm, of 3388 kg / ha, and the lowest yield of 2546 kg / ha was achieved by Denise variety at a distance of 50 cm between row

Researches concerning the influence of organic fertilizers over production and quality at Echinacea purpurea MOENCH. (L.)

Echinacea purpurea (L.) Moench, is a perennial plant, native to North America, from which there are used in therapeutic purpose the aerial parts and the roots. The aerial parts contains flavonoides, polyphenolic acid, coffee acid, volatile oil etc. The medicine prepared from this plant determines the rise of self defense system of the human body ( by mobilizing the leukocytes and extending the phagocytosis activity and inhibits virus multiplication). Since on the international and national market is required that the vegetable raw material to be produced in ecological system without chemical fertilizers, the research conducted at A.R.D.S. Secuieni, during 2008 – 2011 aimed to establish the optimum doses of muck at Echinacea purpurea L. (Moench.) species and track its impact on the herba production but also on the content in active principles. As a result of the performed determinations it was found that the on average over the three years of experimentation the highest height (91.74 cm) and weight (108.26 g) was at the plants from the variant fertilized with fermented muck in dose of 40 t/ha. In this variant the dry herba production obtained during three vegetation years were 39.14 g/ha in the second year, 72.13 g/ha in the third year and 74.02 q/ha in the fourth year. The highest coffee acid content (79.7 mg/100ml tincture) was determined in leaves from plants fertilized with 30t/ha muck and the highest content in polyphenolic acid (2.657 g clorogenic acid) was determined in flowers from plants fertilized with 40t/ha muck

Partial results regarding the behavior of some millet genotypes in the pedoclimatic conditions of A.R.D.S. Secuieni

At the national level, the areas cultivated with millet are very small, this species is not in the attention of researchers and farmers, therefore the information and studies about millet are limited. Starting from 2022, at the Agricultural Research – Development Station Secuieni, research was initiated on the behavior and productivity of five millet genotypes (Panicum miliaceum L.), the results obtained are presented in the present paper. Among the genotypes studied (the variety Marius, the local population Secuieni and the three genotypes from the Vegetal Genetic Resources Bank "Mihai Cristea" Suceava is noted a good adaptability of the species to the A.R.D.S. Secuieni area’s pedology and the 2022’s climatic conditions. Thus, the average grain yield of the tested millet genotypes was 2528 kg/ha - for the variants sown at 12,5 cm distance between rows, 2328 kg/ha - for variants sown at 25 cm distance between rows and 2221 kg/ha – for the varieties sown at 50 cm distance between rows

Behavior of some Romanian triticale varieties in the climatic conditions of the center of Moldavia, Romania

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

Behavior of white and blue lupine varieties in pedoclimatic conditions of the A.R.D.S. Secuieni

Lupine is a source of protein as well as dietary fiber. Lupine seeds are an excellent meat substitute for people who adopt a vegetarian lifestyle and have significant cholesterol-lowering properties, contributing greatly to cardiovascular health. Taking into account the growing interest, in recent years, for this crop, within A.R.D.S. Secuieni was followed the behavior of six varieties of lupine (3 varieties of white lupine and 3 varieties of blue lupine) in the pedoclimatic conditions in Central of Moldavia. In the first year of testing lupine culture, compared to the yield recorded by the control (average experience - 2736 kg/ha), very significant yield increases were recorded for the varieties Wars (3063 kg/ha) and Dieta (4050 kg /Ha). In the second year of testing, only one variety obtained a control higher yield of 2519 kg/ha (Medi). On average, in the two years of testing, lupine yield varied from 2138 kg / ha obtained by the Menhit variety (blue lupine) to 3205 kg/ha at the Dieta variety (white lupine)

The contribution of agricultural research and development station Secuieni, Neamţ county, Romania, to the supply of soybean seed

In the 2008-2012 period, in the Seed production laboratory from Agricultural Research and Development Station (A.R.D.S.) Secuieni, Neamţ county, Romania, were cultivated three varieties of soybean, Granat, Eugen and Onix, created at A.R.D.S. Turda, Cluj county. These varieties were well adapted to the climatic conditions of A.R.D.S. Secuieni, obtaining yields of up to 3000 kg/ha. During 2008- 2012, the following amounts of seeds were produced: PB1(pre-basic seed 1): 11000 kg in 2008, 8700 kg in 2009, 6500 kg in 2010, 5600 kg in 2011 and 3800 kg in 2012; PB2 (pre-basic seed 2): 45900 kg in 2008, 39000 kg in 2009, 67000 kg in 2010, 32000 kg in 2011 and 27000 kg in 2012. The amount of seed from the biological category PB2 ensure, annual, the required for sowing 300- 700 ha of basic biological category, which is delivered to farmers for the sowing of about 5000-12000 ha. Both in the field of seed production as well as in the ecological testing field (comparative cultures of contest) Onix variety presented the greatest adaptability to the pedoclimatic conditions from the Central Moldavian Plateau, achieving the highest yields

Researches regarding the influence of "Secuieni method" on seed yields at monoecious hemp (Cannabis sativa L.) cultivated in the pedoclimatic conditions of Central Moldavia

In this paper are presented the results obtained regarding the evolution of seed culture at monoecious hemp under the influence of „Secuieni method”, method which consists in applying shearings during the plant intense growth phase. When the plants have a number of 5 – 6 floors with opposite leaves is applied a first cutt of the growth peak at 30 - 35 cm from ground level. After the first shearing, from the insertion of the leaves will grow 2 - 6 lateral shoots, that reached the size of 50-60 cm in the short term, between 15 - 20 days, when it is applied the second cutback at 15-20 cm above the first cutback. The big advantage of this method is that it reduces the plant size and allow harvesting by combines directly from the field, by raising the heder under the insertion of the ramifications with fruits. In A.R.D.S Secuieni pedoclimatic conditions, during 2013 – 2015, were performed researches on this method. The biological material used was represented by three varieties created at A.R.D.S Secuieni, respectively Denise, Diana and Dacia. These varieties were seeded with a seed norm of 6 kg/ha and the distances between the experimented rows were: 25 cm and 50 cm between rows. The obtained results have highlighted that the studied factors influenced in a very large extent the seed yield, that varied widely, ranging from 805 kg/ha at the Denise x 50 cm x uncutt interaction and 1115 kg/ha at the Dacia x 50 cm x two cuttings interaction. The correlation between the applyed cutting and the seed yield it was directly, the correlation coefficients (r) were statistically ensured and construed as being very significant at both experienced distances between rows (25 and 50 cm)
