Commercial corn hybrids have a very high yield potential, with valuable features of adaptation to more or less favorable growing conditions. In the particular conditions of technology applied in a certain farm and in particular climatic conditions of the crop year, the production and the efficiency can approach more or less the yield potential of these hybrids, through their comparative testing being able to obtain information to determine the best assortment. Evaluation of the results obtained following the testing of three semi-early corn hybrids, from three different companies, at SC Semtop Group in Iaşi county, at sowing plots of 80,000 and 70,000 germinable grains/m², respectively, and under conditions of optimal assurance of the necessary irrigation water allowed to highlight the hybrids that behave best in the respective conditions.

Development of improved technology, new high-yielding varieties, mechanization, enhanced use of chemical and fertilizers led to increased wheat yields, but this development adversely affected agroecology and labor demands in agriculture. Wheat (Triticum aestivum L.) is the most important crop plants, with a significant dietary importance, all due to the high carbohydrate and protein content of the grain and the ratio between them, which satisfies the requirements of human nutrition. Also, it is one of the ancient crops of agronomic importance, having been taken into cultivation by man about 10-12 thousand years B.C. In Romania, wheat cultivation dates back more than 2500 years. On the shores of the Black Sea, on the sites of ancient cities, coins have been found with the image of the goddess Demeter inscribed on one side and wheat ears on the other. The objectives of the research paper are the DNA-based genetic analysis of wheat (Triticum aestivum L.) and einkorn (Triticum monococcum) cultivars belonging to different subspecies or varieties. This study used 50 wheat genotypes, containing local populations, varieties and breeding material provided by the Vegetal Genetic Resources Bank "Mihai Cristea" Suceava. [ABSTRACT FROM AUTHOR]

The main purpose of the research was to test the productive and qualitative potential of 36 sugar beet hybrids from four international suppliers. The research was carried out in 2021, in two farms with high-performance plant cultivation technologies: Agricola 96 from Tiganasi, Iasi county (irrigated regime) and Agri Farm Ltd. from Balanesti, Neamt county (non-irrigated regime). The maximum biological sugar production in the irrigated system was 11.15 to/ha (hybrid Fiammeta), and in the non-irrigated system 12.20 to/ha hybrid Borjana). Knowing the productive and qualitative potential of sugar beet hybrids depending on the local pedoclimatic conditions, is a basic requirement in choosing the palette of hybrids that will be cultivated in the following years.

Lupinus albus (white lupin) is a crop well adapted to marginal lands and has a large potential for enhanced bio economy use. In general, lupins have the ability to fix atmospheric nitrogen, mobilise soil phosphate and are suitable for low nutritional cultivation. Modern varieties should be selected for high yield of green silage or high yield of seeds which contain more than 20% oil, more than 40% protein and the remaining materials are carbohydrates, mainly oligosaccharides characterized as "prebiotics". In this experiment, three new white lupin sorts were tested in experimental fields. Breeding activities we compensated by optimized cultivation technology for these cultivars. One of the biggest problem in the white lupin cultivation this year was caused by the extreme draught and high temperatures registered during the vegetation period. Results present the observations obtained in 2022 season at the Ezăreni Farm. Comparison of the selected cultivars was performed using two different density condition. Results indicated that white lupins could be an interesting alternative for farmers and can contribute to new optimised crop rotation systems. [ABSTRACT FROM AUTHOR]

White lupin (Lupinus albus L.) is an underutilized crop that started to become extremely interesting for bio and conventional farmers due the high protein content of the seeds and, mainly, due the nitrogen fixation capacity. Nowadays, challenging economic environment and changing climate conditions had led to a bust in fertilizers prices worldwide. Identification and utilization in crop rotation systems of crop with nitrogen fixation capacity is an optimal alternative. One of the biggest problem in the white lupin cultivation technology is caused by the special sensitivity of this species at postemergence herbicide. This sensibility makes weed control a very difficult task for farmers. In this paper we present results obtained in 2022 season at the Ezăreni Farm, Iasi, Romania. Principal yield components were studied and compared among postemergence herbicide variants. Comparative studies were done using the cultivar RUXANDRA, obtained and registered by us.
