The NPPN regulations in PER DIRJEN PAJAK Number 17 / PJ / 2015 state that the NPPN percentage is grouped by region. Where this grouping of regions causes a difference in the percentage between regional groups. In addition, regulations regarding regional grouping are also found in PERMENKUMHAM Number 27/2016 which divides regional categories for the position of notaries. For the purpose of this research, this type of normative legal research uses a statute approach where the legal materials in this study are analyzed using prescriptive analysis techniques. Based on the results of the author's research, it can be concluded that the NPPN grouping by region is one of the manifestations of the Equality principle where this principle provides the same treatment to people who are in the same condition. The sentence is in the same condition can be interpreted as being in the same regional characteristics which are based on considerations using several variables. Broadly speaking, there is a correlation between the regional grouping of the two regulations, which lies in the basic factor for determining regional grouping, that is regional economic growth. The regional grouping that is regulated in the two rules has also fulfilled the value of justice as proposed by Aristotle's theory of justice. Regional grouping which is regulated by the government has clear and firm reasons so that this grouping is not a discriminatory act but is a form of distributive justice.How to cite item: Rachmatullah, A., Anshari, T., Wisnuwardhani, D.

Methods for early diagnosis of drought tolerance in leguminous crops, based on the screening of physiological indices of resistance to stress, are of great importance for the acceler-ated selection of drought tolerant soybean lines. On the basis of the Volga NIISS, laboratory exper-iments were carried out to assess the physiological and biochemical parameters of drought re-sistance of seedlings of promising soybean samples under conditions of osmotic stress. As a result of studying the indicators of seed germination in a sucrose solution and morphophysiological assessment of seedlings of soybean varieties, samples with a high starting growth rate were identified - 156/2014, D-150 and variety Yuzhanka. A strong direct relationship was established between the indices of seed germination on sucrose solution and the index of root length (r = 0.98), between the index of root length and the dynamics of accumulation of free proline under the influence of a stress factor (r = 0.76). According to a comprehensive assessment of the studied samples, it was found that the greatest decrease in growth processes and the smallest accumulation of free proline were noted in samples VNIIOZ-796/11 and Velichava / 2009. Samples D-150, 156/2014 and variety Yu-zhanka were identified as the most drought-resistant.
Physiological aspects of wheat stress resistance
Authors: Manukyan Irina Rafikovna 
Published: February 2022

The article presents the results of long-term studies of physiological processes and oxidative stress occurring in wheat plants under the influence of phytopathogens, mineral fertilizers and fungicides. The criteria for the damaging effect of oxidative stress are the activity of the enzyme nitrate reductase and the concentration of TBK-active products. Normally, a mobile balance is maintained between the processes of lipid peroxidation and the antioxidant system of cell protection. However, under stressful conditions, the ROS content in cells increases rapidly and oxidative stress develops. The resistance of plants to many environmental factors is determined by the ability of the plant to maintain a consistent course of physiological processes, without causing their significant disruption under stress. The relationship between LPO processes and nitrate reductase activity was observed in all wheat varieties. It was found that the varieties reacted differently to the doses of fertilizers. A high negative correlation r = -83 was established between the POL and NRA processes. Many pesticides have additional effects on plants in addition to their main target effect. Fungicides from the triazole class (Byleton, Tilt, Fundazole) were studied. All of them showed antioxidant properties. The strongest antioxidant effect was observed in the fungicide Tilt (propiconazole). The results obtained by us, regarding the close relationship between the processes of POL and NRA, allow us to use fungicides from the triazole class to increase the resistance of plants to various stress factors, activate the antioxidant system in plant cells, and increase productivity. They, as chemical immunizers, are able to simultaneously restrain the development of diseases and affect the physiological and biochemical mechanisms that increase the resistance of plant organisms to phytopathogens and other stress factors.

The researches of impact assessment of agricultural machines’ movers are done in all countries with the use of mobile energy vehicles, which are used for the rolling of the soil with different multiplicity of passes through the fields. Mathematical model is developed taking into account the adding of arable and subsurface layers’ impact on field productivity. It allows one to predict the yield of crops based on impact of agricultural vehicles that perform technological operations, taking into account the width of the track, width of the unit and overlap area. Method of correct determination of indicators of mathematical model is developed. It includes adjustment of the density of the soil layer 0-40 cm and maximum yield value, the exponent of the model. It also includes determination of the coefficients included in it the transformed equation, which corresponds to the mathematical model, after substitution of these indicators in it. Evaluation of the effectiveness of the pressure of the rear tyres of the beet harvester RKM-6 reduction is performed. The pressure became lower by replacing the tires 21,3-24 on the tires 21,3-26 with data on the change in the soil density in 0-20 and 20-40 cm layers where the RKM-6’s tracks.

In 2 years of research, the most successful combination of high yields and good grain quality indicators was obtained when cultivating winter wheat according to the fallow precursor. Thus, the yield in this version was higher than on wheat after winter wheat by 2.7-3.1 times on the version without fertilizers and, accordingly, by 1.8-1.9 times on a fertilized background. For the entire period of research on both precursors, the application of fertilizers contributed to an increase in the yield of winter wheat grains by 0.8-1.2 t/ha for the precursor black steam and by 1.7-1.8 t/ha for wheat. The positive influence of fertilizers affected not only the yield, but also the content of gluten. On average, their application contributed to an increase in the crude gluten in grain by 1.7% (from 22.5 to 24.2%) in fallow and by 3.6% (from 14.5 to 18.1%) in semifallow land. The largest increase in gluten content in the experience options with fertilization for both predecessors was given by Victoria 11 variety - by 2.8 and 5.9%, the lowest Paritet - by 0.6 and 1.6%. The analysis of the economic efficiency of the cultivated varieties of winter wheat showed that the most cost-effective is the cultivation of winter wheat by the predecessor of pure steam, regardless of the background of nutrition. It was found out that the introduction of mineral fertilizers contributed to a reduction in the cost of a unit of production for steam by 48.5%, for the ear predecessor by 32.8%. Analyzing the obtained data on the economic efficiency of winter wheat, it can be noted that the high values of profitability on average for the predecessors and backgrounds of mineral nutrition were obtained by the varieties Sekletia and Tsaritsa, and the lowest – Partner and Paritet.

The main task of wheat production is to obtain high grain yields, with minimal quality losses. It is distinguished by a number of useful properties for breeding, which was used in the creation of shot winter wheat Sharada. This paper presents the results of a comparative analysis of morphostructural and production characteristics, including grain quality, of the initial Sharada wheat and the macromutant forms isolated from it: "Soft from Sharada" and "Line 1/10- 17", against the background of the indicators of the zoned varieties. It is shown that the selected macromutant forms significantly exceed the original Charade in their morphostructural parameters. At the same time, the "1/10- 17 line" of spherical wheat occupies an intermediate place between the cleaved "Soft from Sharada " of wheat and the original Sharada, both in plant height and in the area of the flag leaf. According to the production characteristics of the "1/10- 17 Line", in particular, according to such an important indicator as the weight of grain from the ear, it is already closer to the "Soft from the Sharada" than to the original Charade and the zoned varieties are rising. The increase in the production indicators of the "1/10- 17 Line" and its proximity to the indicators of the macromutant "Soft from the Sharada" wheat, provides its somewhat larger grains and a large number of them. The production indicators of the grain of the macromutant "1/10- 17 Line" in 2021 significantly exceeded the initial Sharada: the number of grains in the ear - 51.6 pieces; the weight of grain from the ear - 2.16 g; M1000 - 41.36 g. and qualitative indicators: protein content 16.4%; gluten content - 41.2%; IDC - 79 units. At the same time, the increase in the production characteristics of the "1/10- 17 Line" practically did not change the qualitative characteristics of the grain, compared with the original fine-grained Sharada and other varieties of spherical wheat, which makes it and the isolated macromutant "Soft from Sharada" wheat quite valuable starting material for use in breeding practice.
