Background:A pot experiment was conducted to determine the effects of alternate irrigation with saline (S) and fresh (F) water on growth, nitrogen uptake and nitrogen use efficiency in Sorghum crop (Sorghum bicolorL.) manured withElaeagnus angustifolialeaves (GM) using15N.Method:Five types of irrigation systems abbreviated as (F, 2F:1S, 1F:1S, 1F:2S and S) and one rate of Green Manure (GM) were employed.Result:Results showed reductions in both Dry Matter yield (DM) and nitrogen uptake (NY) in sorghum grown under different types of irrigation systems as compared with the control (F). The reduction rates of these two parameters increased with increasing number of irrigations with saline water. However,E. angustifolialeaves applied as green manure mitigated the harmful effect of salinity on plant growth parameters. The percent increments as a result of GM application were 9, 19, 43, 43 and 65% for DM, and 33, 30, 42, 36 and 60% for NY in F, 2F:1S, 1F:1S, 1F:2S and S, respectively. Nitrogen use efficiency of added green manure ranged between 25 and 47% in the different types of irrigation systems. Our results indicated that increment of NY in green manured sorghum plants was mainly attributed to its nitrogen availability. According to the availability of S and F water resources, and the economic returns aimed by farmers in the semi-arid regions, it is recommended to use (2F:1S, 1F:1S and 1F:2S) in combination withE. angustifolialeaf GM. Such a procedure can be considered as a promising agricultural practice to improve yield with a proper water resource investment.

In our country average precipitation is annually 250-300 mm, and when we assuming that we need 47.6-43.0 mm precipitation for getting 1 tons of potato and thus means it is sufficient for 6-7tons  yield For more yield use irrigation systems to provide the fields with enough water and humidity is important issue. Cultivation using rotation is not only for producing high yields but also it is important for stabilizing and improving the soil fertility like the first condition of the soil. Irrigated potato fields have a special effect on reducing diseases and increasing yields, lengthening the rotation in the crop rotation sector, increasing the crop structure in rotation, and the use of alternating green manure. The 3-field rotation with green manure has a total yield of 32.0 t / ha, which is 5.4-14.2 t / ha higher than other crop rotations, and the standard yield is 95.7 percent, which is 0.6-5.9 percent higher than other crop rotations.   Усалгаатай талбайн төмсний ургацад сэлгээний нөлөө Манай орны хувьд жилд дунджаар 250-300 мм хур тунадас ордог бөгөөд 1 тонн төмс авахад 40.0-50.0 мм хур тунадас орох шаардлагатай гэж үзвэл 6-7 тонн ургац авахад хангалттай гэсэн үг юм.[3] Илүү их ургац авахын тулд тариалангийн талбайг хангалттай хэмжээний ус, чийгээр хангахын тулд усалгааны системийг ашиглах нь чухал асуудал юм.

ABSTRACT This study evaluates the agronomic and environmental performance of yellow melons produced in an experimental area in Rio Grande do Norte, Brazil, using conventional methods and alternative systems of cultivation based on the rotation of melons with green manure crops. Two types of alternative management systems were evaluated, spanning twelve treatments: i) tillage, with the incorporation of the green manure biomass into the soil via the subsequent planting of melons into that residue, and ii) no tillage, with the maintenance of the biomass on the soil surface with subsequent planting of melons. Agronomic performance was evaluated by statistical analysis of productivity, while environmental performance was evaluated by analyzing the carbon footprint, according to ISO 14067. Agronomic analysis showed that rotation of melons with maize and Brachiaria resulted in a higher yield of melons for export. Assessment of the carbon footprint of this system in relation to the conventional system showed that the rotation system presented a lower carbon footprint. A scenario analysis showed that the carbon footprint can be further reduced by 42.54%, if: i) production takes place in areas already cultivated for more than 20 years, ii) the amount of inorganic nitrogen applied is reduced by 50%, and iii) commercialization of melons begins in the United States. This study shows the importance of rotating melons with green manure crops to increase production in the semiarid region and reduce the carbon footprint of this fruit.

The article provides a scientific and theoretical analysis of the Draft Code of Best Agricultural Practices' content and its significance for the legal support of ecologization of agriculture in Ukraine. We have studied the content of the Draft Code of Best Agricultural Practices and the Draft Code of Proper Agricultural Practice. It was identified the deficiencies in the wording of the scope of these Draft Codes. It is also proposed to extend the Draft Code of Best Agricultural Practices' content to all agricultural producers without imposing any restrictions. It is noted that in the text of the Draft Code of Best Agricultural Practices, it is mandatory to enshrine the provision on voluntary application (based on paragraph 1 of Article 4 of Council Directive 91/676 / EEC on the protection of waters against pollution by nitrates from agricultural sources of 12.12.1991). Also, we have identified the shortcomings of the provisions of the draft Codes regarding land use management regulation, including the use of the crop rotation system. It is concluded that it is inexpedient to duplicate in the Draft Code of Best Agricultural Practices the legislation governing the organization of crop rotations. It is proposed to limit the indication to the relevant regulations. It is concluded that in parallel with the implementation of the Draft Code of Best Agricultural Practices, work should be carried out to implement the cross-compliance approach in Ukraine. This will motivate agricultural producers to comply with the Code of Best Agricultural Practices provisions and contribute to agriculture's ecologization. Keywords: agriculture, Code of Best Agricultural Practices, legal support, ecologization of agrarian activities, nitrates, mineral fertilizers, soil

Rose cultivation requires many inputs for satisfactory production, making the process expensive. Nowadays, alternative practices have been used for sustainable crop production. Green manure is an agricultural practice that aims to maintain or improve soil fertility, increasing its yielding capacity. The objective of this research was to evaluate the effect of green manure with legumes on the yield and quality of ‘Vegas’ roses. Grafted rose seedlings were cultivated in open field for 30 months. Legumes used as green manure and planted intercropped with rose bushes were forage peanut (Arachis pintoi) and jack bean (Canavalia ensiformis). Pigeon pea (Cajanus cajan) was grown in a separate area, cut, macerated, and applied in the rows between rose bushes every 3 months. Plants of control group received no green manure, only mineral fertilizer and cattle manure, as in all other treatments. The experimental design was randomized block with four treatments (three green manure species plus the control) and seven replications. The highest yield and quality of flower stems in ‘Vegas’ occurred with addition of pigeon pea on the soil surface or chemically treated (control). Forage peanut and jack bean are not suitable for intercropping with ‘Vegas’ rose bushes due to possible nutrient and water competition.
