Zn levels in rice are essential for maintaining consumer health. However, Zn deficient plants can reduce levels of Zn in grains and the ability of plants to express their genetic potentials. This study examines the use of cow manure enriched with Zn heptahydrate on increasing Zn levels of broken skin rice. The experiment was arranged in a randomized single factor group design with seven levels of manure dose treatment, namely: 0; 2.5; 5, 7.5, 10, 12.5, 15 tons ha-1, with 3 replications. Spacing was 30 cm x 30 cm with a size of 3 m x 4 m. The parameters observed were plant growth, the weight of 1,000-grain, percentage of empty grain, production, Zn and protein contents of the brown rice. The collected data were analyzed using analysis of variance with a confidence interval of 5%, followed by the Duncan test of 5%. The results showed that the application of cow manure with a dose of 10 tons ha-1 enriched by 5 kg ha-1 Zn heptahydrate could increase the number of productive tillers, weight of 1,000-grains, production, Zn and protein contents of the brown rice as well as suppress the grainy rice grain of Mekongga variety of lowland rice on the intermittent flooding.   Keywords: brownrice, cow manure, irrigation system, Zn heptahydrate

O aumento da produtividade das áreas cultivadas no Rio Grande do Sul deve-se principalmente ao uso de sistemas de irrigação. Porém, o manejo inadequado destes sistemas pode ser um fator limitante à produção das culturas irrigadas e dentre os elementos a serem considerados para um eficiente controle de regas, pode-se destacar o indicador de déficit hídrico que pode ser via solo, planta ou através da estimativa da demanda evaporativa da atmosfera. Este trabalho teve por objetivo avaliar a produtividade de dois híbridos de milho cultivados sob estratégias de irrigação com diferentes indicadores e lâminas, no município de Jaguari, RS. Os tratamentos constaram de três diferentes estratégias de irrigação: T1 - sensores dielétricos de umidade do solo, T2 - 100% de reposição da evaporação de Tanque Classe A e T3 - 80% de reposição da evaporação de Tanque Classe A. Os híbridos de milho testados foram: BM 1201 e BRS 3150, utilizando-se um sistema de irrigação do tipo mini-pivô central. Na colheita determinou-se os componentes de produção, que foram submetidos a análise de variância e comparação de médias. Os manejos de irrigação influenciaram nos componentes de produção e no rendimento final dos dois híbridos testados. O híbrido BRS 3150 apresentou maior produtividade comparado ao híbrido BM 1201 para as estratégias com sensores de umidade de solo e reposição de 80% da evaporação do Tanque Classe A, sendo que para a estratégia de 100% da evaporação do Tanque Classe A, o híbrido BM 1201 apresentou maior produção.   UNITERMOS: Zea mays L., manejo de irrigação, parâmetros de cultura, rendimento de grãos     SOARES, F.C.; PEITER, M.X.; ROBAINA, A.D.; PARIZI, A.R.C.; RAMÃO, C.J; VIVAN, G.A. MAIZE HYBRIDS PRODUCTIVITY RESPONSE, CULTIVATED UNDER DIFFERENT IRRIGATION STRATEGIES     2 ABSTRACT   This work aimed to evaluate the yield of two corn hybrids cultivated under different irrigation strategies, in Jaguari, RS, Brazil. Treatments consisted of three different irrigation strategies: T1 - measurement sensors of soil moisture, T2 - replacement of 100% of evaporation of Class A Evaporation Pan and T3 - replacement of 80% of evaporation of Class A Evaporation Pan. The tested corn hybrids were BM 1201 and BRS 3150. The experiment was bifactorial, and a central mini-pivot irrigation system was used. At harvest time,  the plants were located in a stove at 65ºC, until reaching constant mass and yield components were determined. Data were analyzed through the analyses of variance and mean comparison, (Tukey's test) at 5%. The irrigation management influenced the yield components and the final yield of the two tested hybrids; the hybrid BRS 3150 presented a greater productivity compared to the hybrid BM 1201 for measurement sensors of humidity and replacement of 80% of evaporation of Class A Evaporation Pan, whereas the hybrid BM 1202 had bigger production for the replacement of  100% of evaporation of Class A Evaporation Pan.   KEYWORDS: Zea mays L., irrigation management, culture parameters, grain yield.

Purpose. Finding ways to increase the gross production of corn grain and increase the culture of farming practices in the country. Methods. Abstract and logical methods are used: analysis, synthesis, induction, deduction, analogy, comparison, generalization, as well as a systematic approach to the features of technical-technological, organizational-economic and market conditions of the whole complex of growing corn hybrids functioning. Results. The list of competitive methods for different technologies of growing corn hybrids for grain is given. The results of scientific observations of corn crops in different years of cultivation in different climatic zones of Ukraine are highlighted. The actual and most cost-effective models of growing corn for grain have been studied. The conditions for improving the country's grain production have been established, which are based on the principle of maximum realization of the significant genetic potential of productivity of new corn hybrids. And this in its turn involves further improvement of technologies for growing each hybrid separately with the effective use of its genetic capabilities in accordance with the specific conditions of the region of growing. The need for additional research on the biology of the development of new corn hybrids of intensive type under climate change is revealed. Examples of successful introduction of the effective models of cultivation corn hybrids technology are given. Conclusions. Realization of the genetic potential of modern corn hybrids will significantly increase grain production and stimulate development of the processing industry. Given the biological characteristics of new corn hybrids and development of new technologies for their cultivation, there is a need to optimize the interaction of hybrids with available hydrothermal resources and organized factors, which will ensure fuller realization of their potential in a particular region.

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

Applying water efficiently is increasingly important for dairy farmers and other users of surface and groundwater resources to maintain sustainable production. However, irrigation is rarely monitored. We used a questionnaire survey and measurements of five spray irrigation systems working in normal farm conditions to make observations on how efficiently irrigation is being managed. Survey results from 93 dairy farmers showed that, although the farmers believe they know how much water is being applied during irrigation, only 60% make measurements, and about 18% measure irrigation uniformity. Catch-can measurement of irrigation application depth for the different spray systems indicated large variability in application depths during irrigation, and field distribution uniformity ranged greatly between the different systems, decreasing in the order of centre pivots >travelling irrigators> K-line. Changes in irrigation system settings were sometimes made without considering application depths or uniformity. If our five case studies are typical, they may explain the large range of seasonal irrigation amounts recorded in the survey. We recommend that farmers monitor irrigation application depths and uniformity to help manage irrigation water efficiently and to help them estimate the value of irrigation to their enterprise.
