The current study presents some stability parameters (coefficient of variation, environment variation, regression coefficient, deviation from regression, coefficient of determination and ecovalence) of grain yields and the main components of its. Twenty-two spring wheat cultivars were tested in yield trials during three years being analyzed the number of grains per spike, thousand kernel weight and spike density The genotypes: Durom and Marcius indicated over the experimental years, a high stability for grain yield, based on three or more parameters (CV, s2, b, sd2) and a good adaptation. Corso and Henica genotypes have a good stability for number of grains per spike with a medium number of grains, and TD 1524-71 is the most unstable genotype for thousand kernel weight. Regarding the correlation between stability parameters for analyzing characters there is a different and additional reaction according to differently performance of genotype.

The purpose of this research is to study the potential for yield and quality indicators for winter wheat genotypes in terms of pedological and climate condition and applied technology, at ARDS Turda during 2014 – 2015. Depending on the climatic conditions that are associated with applied technology is a decisive factor in successful wheat crop for all genotypes that were studied at Ards Turda during the 2014 – 2016. That’s wy each genotype responded differently to the conditions of the ARDS Turda also through the two levels of fertilisations applied in the winter with fertilizers 20:20:0, 250 kg/ha assuring 50 kg/ha N and P active substance and second level of fertilisations with 150 kg/ha ammonium nitrate assuring 50 kg/ha N active substance. All genotype that were studied in terms of yield and quality indicators were influenced by the fertilization level. The influence of pedo-climatic conditions, applied technologies and fertilizers level at ARDS Turda showed that all genotypes with small yield had higher protein and gluten content respectively Zeleny index.

Using Near Infrared Spectrometry has become lately quite a developed technique in the different physico-chemical parameters of the feed as a procedure is extremely elegant and precise use. This paper aims to highlight a way of direct analysis method undestructive protein and total nitrogen using near infrared spectrometry in conjunction with reflected attenuated total. Tests were conducted on samples of maize cob and maize stalks from The Research - Agricultural Development Turda. Samples done at each variant separately. Each sample was subjected to destructive method calculations: Kjeldahl method for determinating the protein, and then collected with NIR spectrum. We have built mathematical models for both the cob and stalks, based on these techniques and multivariated analysis allows the determination of an error prediction for the best protein 0.5% and the total nitrogen of 0.1%.

Presented research was carried out in 2021 and 2022 on the Felix soybean variety at the Agricultural Research and Development Station Turda, located in the Transylvanian Plain, Romania. In this experiment, complex fertilizer NPK 20:20:0 was applied as a basic fertilizer in a dose of 200 kg ha−1 at the sowing stage, to which foliar fertilizer Agro Argentum Forte treatment was added in different doses and at different application stages. The main purpose of the study was to identify the suitable stages of foliar application in soybean cultivation for effective vegetative development, yield, and quality purposes. The impacts of the fertilization system and the climatic conditions on the physiological parameters, assimilation, yield, and quality were evaluated. Technology showed that the physiological parameters were positively influenced, following the foliar fertilization with Agro Argentum Forte, with average assimilation values recorded above 23.0 μmol CO2 m−2s−1 in the year 2021 and 22.4 μmol CO2 m−2s−1 in the year 2022. Soybean crop was influenced by climatic conditions and the application of foliar fertilizers in different phases of growth and development, obtaining higher yields, as well as higher protein and oil content. The soybean yield and quality indices (protein, oil, and mass of a thousand seeds) were higher in 2021 than in 2022 for the variants treated with foliar fertilizers compared to the control, resulting in an improvement in seed quality in 2021 with a yield of 3560 kg ha−1, while 2022 saw a lower yield of 1805 kg ha−1. The application of basic mineral fertilizers in combination with foliar fertilization had a significantly positive impact on the quality indicators of soybean seeds. The highest yields were achieved when the foliar treatment was applied in the early pod formation stage.

In this paper we studied two types of maize hybrids of two precocity groups according to FAO 250 – 320 (early) and FAO 340 – 450 (mid- early). Therefore we chase the evolution of each studied maize hybrid and how they turn account on climate condition of SCDA Turda
