The paper aimed to present the effects of different types of fertilizers on several soybean quantitative traits (plantheight, first pod height, number of pods per plant, number of grain per plant, grain yield per plant, 1000-grain weightand grain yield) and seeds’ composition (dry matter, protein content, ash content, oil content, total carbohydrates, totalflavonoids, total phenols and total carotenoids content). The experiment was conducted in 2019, in the experimentalfield of Soybean Breeding Laboratory from the Agricultural Research and Development Station Turda (ARDS Turda),and included 15 fertilization trials. An early maturing soybean variety (Caro TD) obtained at ARDS Turda was used forthe experiment. The results showed that increases in yield were obtained with various combinations of the commercialfertilizer. The application of N20P20K0 combined with seed treatment and foliar Bio-fertilizer with 80% amino acids,significantly increased the values for all quantitative traits and also grain yield, while with respect to seed compositionthe best ranked type of treatment was T7(ecological products).
Soybean is one of the most important crops in the world due to its high nutritional value and also because its importance in crop rotation. Soybeans have relatively high requirements for soil nutrients, but also for its structure. Adequate nutrient support can ensure both high and stable yields and a high fat and protein content, soybeans being considered an important source of macronutrients. In order to estimate the genetic parameters of some yield components and quality traits in soybean crop, a two years polifactorial experiment was carried out at Research and Development Station for Agriculture Turda, Romania (RDSA Turda). The experiment had an area of 57 x 35 m and was based on a subdivided parcel design with three replications, using plots of 5 m2. It included 13 soybean cultivars from three maturity groups fertilized with 3 different doses (without fertilization, 150 kg/ha, 200 kg/ha, 250 kg/ha complex fertilizer) and two mineral fertilizers (NPK 16:16:16 and NPK 27:13.5:0). Seven varieties (Perla, Carla TD, Felix, Onix, Caro TD, Ada TD, Raluca TD) and six perspective lines (T-295, T-161, T-165, T-6117, T-166, T-6126) developed at RDSA Turda were used for the experiment. Yield, insertion of the basal pods, number of pods/plant, number of grain/plant, grain weight/ plant and thousand kernel weight (TKW), were studied. Regarding the quality parameters, fat and protein content were analysed. The results obtained reveald that yield, yield elements, protein and fat content were very high influenced by the genotype. Small influence of the experimental factor dose of fertilization in yield was observed. Regarding the genetic parameters, for seed size (TKW) was recorded high values for heritability in broad sense, for genetic advance and also for genetic advance in percent, sugesting that soybean grain yield cand be improved by the direct selection of genotypes with high values of TKW.
Soybean is one of the most important sources of vegetable oil and protein. The aim of this study is to evaluate the behavior of 75 European soybean genotypes from four maturity groups regarding the influence of climatic conditions of 2020 on soybean main growing and development stages. The experiment was conducted at the ARDS Turda in 2020, using a complete randomized block design with three replications. Dates of emergence (VE) and beginning of flowering (R1), were recorded for all 75 soybean cultivars from each of the four maturity groups (000 to I). Results obtained show that growing, and development stages of the studied soybean genotypes are according both with: thermal units and daily period from sunrise to sunset. Effects of daylength and temperature on soybean development were estimated. The rate of development to flowering was fastest for the very early genotypes than for genotypes in the semi-early maturity group (MG).
Soybean is considered one of the main multipurpose crop and the quality of soybean based products have increasingly received attention. Soybean growers have invested into agronomic practices to maximize production and increase its potential, one of the practices are the usage of foliar fertilizer. In order to quantify the effects of foliar fertilization on soybean seed quality, an experiment was carried out at Research and Development Station for Agriculture Turda, in two consecutive years (2020-2021) and was based on a randomized blocks design with three replications. Seventy-five soybean genotypes from four maturity groups were analyzed. A small influence of foliar fertilization on soybean yield was observed with a slight decrease for the early genotypes when foliar fertilization in both growth and development stages were applied. Regarding the quality, an improvement of the chemical composition of soybean seeds can be reached by applying foliar fertilizers. The results from this study revealed that yields was not increased by treatments applied on soybean growing season.
"Soybean is an important economical crop used for human consumption, animal feed and industrial raw material. Also, soybean is succesfully used in crop roatations with the main cereal crops because it’s biological nitrogen-fixing capabilities. A great diversity of pests and diseases including nematodes, insects and phytopathogenic fungi are known to affect soybean crop. From plant emergence to grain maturity, pests Tetranychus urticae and Etiella zinckenella, pseudofungi Peronospora manshurica and fungi Fusarium sp. and Botrytis cinerea can cause economic damage. In this study was evaluated the influence of tillage systems, different types of fertilizers and pesticide treatments on the most economical important diseases and pests of soybean crop in a field experiment at Agricultural Research and Development Station (ARDS Turda) in the climatic conditions of 2020. Teo TD, an early maturing soybean variety created at ARDS Turda, was used for the experiment. Based on the assessments made, soil tillage system, fertilization and control of pests and diseases have differently influenced the downy mildew and T. urticae attack. To reduce the attack of pathogens in soybean crop, the best technological option is plowing, balanced fertilization and application of fungicides, either without or in combination with an insecticide. The T. urticae populations developed on mineral, organic and green fertilized plants. Integrated control methods must combine agro-technical measures with the application of chemical treatments in accordance with the warning of the appearance of the first adults. "
