SOIL MICROBIOLOGICAL ACTIVITY AND PRODUCTIVITY OF MAIZE FODDER WITH LEGUMES AND MANURE DOSES

SOIL MICROBIOLOGICAL ACTIVITY AND PRODUCTIVITY OF MAIZE FODDER WITH LEGUMES AND MANURE DOSES

1.12 to 2.03 (Macassar) times greater than the control (absolute and chemical) treatment, respectively. This increase may be related to the low phosphorus (P) supply to the plants, thus increasing their enzymatic activity (DICK; SANDOR; EASH, 1994). Pigeon pea may be competing with maize plants for the use of phosphorus (P), leaving such soils with lower phosphorus availability and consequently, contributing to the increase in acid phosphatase activity. In addition, crop biomass and green manure treatments may also stimulate plant growth, metabolism, microbial biomass and consequently, enzymatic production and activity (PIOTROWSKA; WILCZEWSKI, 2012).

Study of Callus Formation, Regeneration, and Possibility of Mucilage Production in the Medicinal Herb Flax

Study of Callus Formation, Regeneration, and Possibility of Mucilage Production in the Medicinal Herb Flax

In this research, the responses of roots and leaves of seedlings produced from in vitro germination of flax seeds were studied. For this purpose, a factorial experiment including culture media with 10 experimental treatments each with three replications that consisted of combinations of micro samples and hormone was carried out using the randomized complete block design to study the extent of callus formation. Three hormonal combinations were used to prepare the culture media for the callus regeneration phase, and the MSFUL was employed as the base culture medium. Results of data analysis showed the most suitable culture medium for callus formation in flax was culture medium number 4(1 mg/L NAA and 2 mg/L BAP). Regeneration results indicated culture medium number 2 enjoyed the maximum callus growth rate, and regeneration culture media numbers 1 and 3 had the same callus growth rates. Culture medium number 2 was suitable for regeneration, callus formation, and callus size, while culture medium number 3 was more suitable in relation to the quantities of produced Flavonols and Flavonoids, and culture medium number 1 with respect to the amount of produced mucilage and harvest index

Public and Private Inputs in Aggregate Production and Growth: A Cross-country Efficiency Approach

Public and Private Inputs in Aggregate Production and Growth: A Cross-country Efficiency Approach

Deterministic and stochastic estimation methods provide similar results and conclusions. Notably, non-parametric and parametric results coincide rather closely on the countries movements vis-à-vis the possibility frontier and on their relative distances to the frontier. The number of countries that can be nominated as efficient was stable throughout the period, with six or seven countries usually on the frontier (Belgium, Canada, Spain, Italy, Japan, Portugal, and the USA). In addition, it is worthwhile noticing the steady improvement in (technical) efficiency throughout the time sample for such countries as Ireland, Norway, and Finland, with the first two countries reaching the efficiency frontier in 2000, and depicting the biggest TFP change in that period. An opposite development can be seen for the case of Japan that shifts away from the efficiency frontier between 1970 and 2000.

THE IMPORTANCE AND POSSIBILITY OF CARCASS QUALITY IMPROVEMENT IN HUNGARIAN PORK PRODUCTION

THE IMPORTANCE AND POSSIBILITY OF CARCASS QUALITY IMPROVEMENT IN HUNGARIAN PORK PRODUCTION

The slaughter data of the National pig database was analysed by the authors. The authors investigated the results of the (S)EUROP grade scheme, which showed the connection between the pig proportions fell into the various grade classes and their prices. The analyses started when the introduction of the (S)EUROP grade scheme took place in 1997 and was based on the official database published each week. For the sake of better overview the results were summed up to monthly intervals. The authors found that in the first period (shortly after the introduction of the grade scheme) the prices of the slaughtered pigs fell into the various grade classes differed from each other by 6-7 %. As a result of the (S)EUROP grade scheme’s introduction the proportion of the slaughtered pigs fell in the grade classes E and U increased from 18% to 27% and from 37% to 44% respectively. The proportions in the R, O, and P classes consequently decreased. Following the first period no changing pattern was found concerning these proportions which means that the improvement of the graded slaughter pigs stopped. Investigating the possible explanations the authors realised that the price differences between the grade classes decreased from 6-7% to 4-5%. Thus the meat processing industry in fact was paying more for one unit lean content of slaughtered pigs when fell into the worst categories than for those which can be found in the best categories. This however does not provide any motivation for the producers for improving carcass quality, which can only be obtained through higher costs. It can be concluded that carcass quality improvement is an important requirement for Hungary. Concerning the EU members the graded slaughter pigs can be found in the E and U categories almost exclusively. The same ratio is only 65% in Hungary. Therefore the modification of slaughtered pig prices of the E and U grade classes is vital in order to motivate the production of slaughtered pigs falling into these categories. Unless this aim is fulfilled the Hungarian slaughter pig sector loses its competitiveness.

Adopting this new format represents a new phase in the history of RBH. Our historiographic tradition of privileging hard copy texts and files made us feel somewhat fearful of this new media of writing. Nevertheless, the fast transformations suffered by the current editorial market imply in a growing trend to the digitalization of publication. The electronic publication provides opportunities for the use of technology in order to enhance the historiographic production, thereby, there is the possibility of writing history far beyond the reach of words and, therefore, narratives can be composed by images, hypertexts, environments in 3D and everything else that digital support can offer to the researcher. Such a change also intends to internationalize the Brazilian historiographic production, besides reducing costs and logistic difficulties involving storage and distribution.

The analysis of solidification process of ferritic-austenitic cast steel

The analysis of solidification process of ferritic-austenitic cast steel

The possibility of increasing the hardness of the copper- containing alloy by ageing has made it reasonable to choose cast steels with copper addition for castings working under corrosive-erosive conditions, such as elements of pump casing, impellers, connector pipes, guide vanes, etc [3]. But the quantity of defected castings (due to hot cracking) and the difficulty with the copper-containing scrap management at piece production have resulted in the fact that Polish power industry still uses imported elements [4].

Production of cabbage grown in pots containing legumes’ root and shoot

Production of cabbage grown in pots containing legumes’ root and shoot

maize from green manures C. juncea and Mucuna sp. was 30% of N from the sunnhemp shoot and less than 20% of N added by the roots of mucuna (Ambrosano, 1995). However, in most studies, green manure root effects are not usually taken into account. This occurs due to the difficulty of roots’ collection and quantifying their N content (Khan et al., 2002). Thus, studies on the effects of different parts of legumes on crop production are expected to contribute to greater scientific understanding and future green manure management. The aim of this study was to assess the effects of root, shoot or whole plant of Crotalaria juncea and Canavalia ensiformis green manure on the growth and yield of cabbage grown in pots.

The comparison of the structure and microhardness of the tool steel C90 and HS 6-5-2 remelted with the electric arc

The tool steels consistute a very important group of materials used for the production, not only tools, but also machine ele- ments, that need to have the increased strength, for example the high-speed steels are used on the rolling bearing operating in high temperatures [1]. Modern technologies such as: laser treatment, electron treatment, CVD, PVD methods, give the possibility of forming the structure of the surface layer of steels providing the demaded properties. The economic factors direct research in using the plasma of the electric arc for shaping the surface layer of the machine elements and tools. Advantages of that method are the possibilities of receiving wider treated areas with one stream of the heat in comparison with the laser technologies or electron

Potential for introducing improved production practices in food legumes with

Potential for introducing improved production practices in food legumes with

ABSTRACT: The restricted maximum likelihood method was used to assess performance following the introduction of improved varieties of chickpea and mungbean (an important source of plant protein in Afghanistan) as compared to local varieties using 242 farmer participatory demonstrations laid out in eight districts in Baghlan, Balkh and Uruzgan provinces in Afghanistan from 2009 to 2012. The impact of the varieties introduced on the enhancement of security of food and nutrition of farmers adopting such technologies was also assessed. Taking an average over the study period, chickpea improved varieties (Madad and Sehat) recorded 56 and 72 % more yield over the local ones, respectively, while in case of mungbean varieties, Mai 2008 and Maash 2008 recorded 22 and 30 % more yield over local ones respectively. Though there is a significant yield difference between the improved and the local varieties of both crops, the difference between the improved varieties of chickpea was not significant while it was significant in the case of mungbean. The study revealed a non-zero variance component for variety type [improved vs. local] × year within district interaction for the yield of chickpea while none of the interactions in mungbean had a positive variance component. Risk analysis showed that at a chosen probability level of 90 %, the improved varieties yielded more than local varieties in both crops (> 1.0 t ha −1 ). Thus, the study highlighted the scope for enhancing the security of both

Technology for sustainable agriculture and agro-industry

Technology for sustainable agriculture and agro-industry

noted that the total potential of available farm land is limited and it should be discussed on how it should or could be managed from the global point of view. The world's cultivated farm land is currently almost 1.3 billion hectares and it is estimated that it can possibly be increased up to 1.5 billion hectares at the maximum because a certain amount of those cultivated farm lands is also changing into desert year by year (Figure 3). Even if more new farm lands are further developed for food or energy bio-resource production, they may bring more environmental jeopardy such as deforestation. Not only for the issue of food but also for energy that more additional farm lands are needed to meet the requirement for both production increase of food and energy. It seems almost impossible to newly develop and reclaim farm lands in two dimensions. A plant (green) factory may, however, provide some possibility to ease this problem if high-rise buildings or architecture are constructed for growing food crops or energy ones. In relation to the topic, a huge structure of 2000 metres high consisting of thousands of truss structural members was proposed as one of the possible future city plans (Figure 4) [9]. This green (plant) factory might play an important role in growing bio-resources used for food and energy in future. Figure 4 shows one of the possibilities of growing and producing food and energy resources in a very huge truss structure based on a technology innovation of the future.

Quality of sorghum silage with leucaena

Quality of sorghum silage with leucaena

An alternative little explored is the use of legumes in the production of silage, it is known that the addition of legumes into grass silage improves the quality of the ensiled mass by increasing the protein content, improving nutrient digestibility, intake and aspects related to the production like weight gain and milk production, due to its high nutritional value (Epifanio et al., 2016; Santana, Cisneros, Martínez, & Pascual, 2015). It is possible to ensile almost all types of forage; however, few species meet the requirements of quantity and quality, and it is important to analyze which species are more economically and nutritionally desirable. Silages of legume alone have poor quality due to high buffering power and low soluble carbohydrate content (Lima, Lourenço, Díaz, Castro, & Fievez, 2010). Nevertheless, the use of legumes mixed with grasses improves the quality of the ensiled mass and increases the protein content when compared to the silage of corn or sorghum alone (Leonel et al., 2008; Lima-Orozco, Castro-Alegría, & Fievez, 2013).

Contribution To The Study Of Reproduction Parameters Of The European Conger Eel Conger Conger Linnaeus 1758 From The Western Algerian Coasts Oran Bay Algeria

Abstract: The demographic structure of the population of the European conger eel (Conger conger; Linnaeus, 1758) from the Western coast of Algeria is made up of young individuals who enlarge more quickly than they grow. The estimated parameters of growth using the equation of Von Bertalanffy are: For females: L∞ = 134 mm ; K= 0,13 ; to = -0,69. For males: L∞ = 108 mm ; K= 0,23 ; to = -0,67 The specimens with most advanced stage of maturation appeared from February to April 2012 for both, female and male. The size at the first sexual maturity was 78 mm in males and 88 mm in females. The sex-ratio was in favor of the females lasting almost all the year excepting during September, December (2011), and January 2012 for males.

Other electrochromic parameters were studied, such as response time, efficiency and reversibility. Chronoamperometric analysis (Figure 8) was also carried out, with follow-up of optical density variations in situ, using a 450 and 700 nm wavelength, in which there was a successive application of –0.6 V for 60 s and 1.2 V for 60 s, and the evolution of color variation on the material could be observed as a result of the cycles. It was also noted that the optical density (OD) variation in situ was 0.73 (450 nm) in the first cycle and increased to 1.09 in the last cycle.

Evaluating the influence of selected parameters on sensitivity of a numerical model of solidification

Evaluating the influence of selected parameters on sensitivity of a numerical model of solidification

Presented paper contains evaluation of influence of selected parameters on sensitivity of a numerical model of solidification. The investigated model is based on the heat conduction equation with a heat source and solved using the finite element method (FEM). The model is built with the use of enthalpy formulation for solidification and using an intermediate solid fraction growth model. The model sensitivity is studied with the use of Morris method, which is one of global sensitivity methods. Characteristic feature of the global methods is necessity to conduct a series of simulations applying the investigated model with appropriately chosen model parameters. The advantage of Morris method is possibility to reduce the number of necessary simulations. Results of the presented work allow to answer the question how generic sensitivity analysis results are, particularly if sensitivity analysis results depend only on model characteristics and not on things such as density of the finite element mesh or shape of the region. Results of this research allow to conclude that sensitivity analysis with use of Morris method depends only on characteristic of the investigated model.

The influence of the arc plasma treatment on the structure and microhardness C120U carbon tool steel

The influence of the arc plasma treatment on the structure and microhardness C120U carbon tool steel

The examination of the structure and microhardness of surface layer of C120 U carbon tool steel after arc treatment are presented in the paper. They are compared with the properties obtained after conventional hardening. The GTAW (Gas Tungsten Arc Welding) method was used. The remelted zone consists of dendritic cells and columnar crystals. Inside the columnar crystals dependent to current arc plasma intensity the martensite or lower bainite was observed. The cooling rate of the remelted zone is similar to the cooling rate obtained in the classical heat treatment. The maximum hardness 650 HV0,1 was measured in material after treatment with a smaller current intensity of arc plasma – 60A. Increases of the current intensity of arc plasma from 60 A to 110 A (for fixed speed rate of source) lead to increases the depth of the remelted zone from 1,2 to 3,1 mm. Thickness of the heat affected zone in the all specimens was similar (1,9 to 2,1 mm).
