Pedoclimatic elements and smart technology act simultaneously on the biological processes of agricultural crops and on the level of harvest, which requires the study of their correlation to determine the continuous influence of these factors in obtaining the planned levels of production. In Romania, annually, over 2.1 million hectares of wheat are cultivated, with annual productions of over 10 million tons, placing wheat crops in the first place as economic importance. Knowing the management of natural resources in quantitative terms is especially valuable when we talk about their sustainable use. Our evaluation includes in this paper the relationship between the pedoclimatic resources of South-Eastern Romania and the zoning of wheat varieties in order to obtain superior quantitative and qualitative productions. The last 11 agricultural years are analyzed, both in terms of the influence of global warming and in terms of wheat zoning to obtain sustainable production to highlight the genetic potential of the varieties under the conditions of the Brailei Plain. A stability of the varieties Glosa, Miranda, Litera (varieties over 15 years old) was observed, but not least of the new ones created by the National Research and Development Institute from Fundulea such as: Pitar, Ursita, Adelina, Izvor.

The five-year research devoted to the study of harvesting methods and desiccation effects on the yields and quality of oil seed flax of dual use was conducted in the field conditions on the dark-chestnut soil in the South of Ukraine during 2013-2017. The study defined the highest effectiveness of pre-harvesting desiccation of the crop by glufosinate ammonium in the dose 2 L ha-1 followed by direct harvesting that can increase the yield of flax seeds by 0.15 t ha-1 or by 11.9%, and the yield of flax straw – by 0.22 t ha-1 or by 12.7%. At the same time, the increase in the yield is accompanied by the improvement of qualitative parameters of the straw through better orientation of the stems in a roll, the share of fibres, which are longer than 200 mm, in comparison with the separate harvesting increases by 8%, and the contamination of the straw decreases 3 times in comparison to the variant without desiccation. Desiccation conducted by using glyphosate preparation in the dose 3 L ha-1 allowed increasing of the net profit by 15.67 euro ha-1. [ABSTRACT FROM AUTHOR]
