“…2). Analyzing the influence of fertilization level on wheat production it was noticed that the additional amount of fertilizer has determined a very significant increase of the production obtained in comparison with the unfertilized land (Ibragimov et al, 2012;Gao et al, 2009).…”

Conservation agriculture is an alternative to conventional agriculture and one of the most efficient systems for sustainable agricultural development, stimulating soil biological activity, increasing organic matter and humus content. In order to evaluate the impact of the conservation agriculture system compared to the conventional agriculture system on wheat yield, a bi-factorial experiment on wheat crop based on split-plot model was organized in the Transylvania Plain, Romania, where there are a few research results in the field and the area has a high potential for the implementation of conservation agriculture system. First factor (' A') was agriculture system, having two levels: ' A1' tillage (classic) system and ' A2' no-tillage system, and the second, 'B' factor was fertilization, with three levels: 'B1' no fertilization, 'B2'-N 80 P 40 kg/ha, which is the average level practiced by farmers in the area and 'B3'-N 150 P 75 kg/ha, which is the recommended level for obtaining a high production performance specific to ' Ariesan' wheat cultivar used in this experiment. The results pointed out that, in comparison with conventional agriculture, the application of no-tillage system determined a lower wheat yield by 353 kg per surface unit. Fertilization assured a significant increase by 610 kg wheat grains per ha. In the case of the conservation agriculture system, the highest production gain was 1,260 kg/ha for 'B3A2' level compared to 'B1A2' level, where the highest fertilization level was applied. The lowest production gain was 410 kg/ha registered by 'B3A1-B1A1' which was the highest fertilizer dose in case of conventional agriculture. In conclusion, the application of no-tillage system increased the efficiency of fertilization in terms of wheat yield compared to the classical agriculture. As a result, it is recommended as farmers dealing with wheat cropping in the area and also in other regions with similar soil and climate conditions to implement conservation agriculture.

In Uzbekistan, special attention is paid to the cultivation of lentils and such types of grain are characterized by high quality indicators and physicochemical characteristics. In Uzbekistan, special attention is paid to the cultivation of lentils. Such types of grain are characterized by high quality indicators and physicochemical characteristics. The physico-chemical parameters of local varieties of lentil grains were studied. The technological characteristics of lentil grains were established, the distinctive characteristics of lentil grains in comparison with well-known varieties have been determined. It was found that in the process of deep processing of lentil grain to obtain a protein isolate, proteins retain their native conformation, as evidenced by the position of the absorption bands Amide I, Amide II and Amide III in the analysis of IR spectra.
