Frequent alternations of high and low temperatures and of rainy and dry weather, which were increasingly felt in recent decades have reduced harvests. Thus, the identification of varieties with genetic characteristics that provide a better adaptability presents a particular importance. Although a cultivar is known as the most important technological link in terms of production stability, the quantity and quality are influenced by the climatic conditions. Observations were conducted in the experimental fields of th...

The soil tillage system through the intensity of soil mobility influences its physical state, the capitalization of the fertilization system applied, and together they condition the water conservation in the soil, respectively the development of maize crop. The arable lands damaged by intensive conventional pratices are a cause of the loss of carbon and water in the soil, to a larger or smaller scale, according to soil, season and especially the stage of damage of soils. The purpose of the paper is the research of...

Research aimed at testing new PIONEER oil rape hybrids cultivated on three different fertilisation rates in the soil and climate conditions of the Banat?s Plain, near Jebel, Timis County, Romania. The soil is a typical cambic chernozem, moist phreatic, pH 6.21, and 2.07% humus in the Ap horizon. The climate in the area is moderate continental with little Mediterranean and ocean influences favourable to oil rape cultivation. The trials organised between 2014 and 2016 were bifactorial, with Factor A represented by t...

This article aims to assess the actual possibilities of thermal degradation during the processing of the plastic and the mixed plastic waste. For these materials, it can be problematic to find utilization in some of the available recycling processes. These selected materials have been processed in the prototype unit for thermal degradation in the non-oxygen environment. This technological equipment is designed for continuous feeding of the input material, the retort is heated by flue gas from natural gas and the d...

The tailings resulting from surface excavation mining can turn into areas used for the re-cultivation of various species of plants, which represents, in fact, an ecological reconstruction and rehabilitation of degraded fields. The re-cultivation of tailings can underpin farming or forestry, and the research conducted in this regard recommends using organic and mineral fertilizers in order to provide the necessary nutrients, increase the organic matter content and also improve the soil structure and microbiological...

One of the main objectives of EU energy policy is to increase the share energy from renewable sources to 20% by 2020, in view of increasing this share in the coming years. Sustainable and perspective source in diversification of share and its increasing are targeted grown energy crops. In Slovak regions, the share of the renewable sources in the gross final energy consumption is only 11.6%. Potential for growing energy crops is in all Slovak regions. In terms of soil factor is the possibility of growing on an area...

Nowadays the renewable sources of energy are gaining more and more in importance to meet the society requirements of energy in a sustainable way. Biomass is among the renewable sources of energy which is known and used since ancient times and it is of great importance for present as well as for the future. One source of biomass are agricultural crops through their residues but also as agricultural crops specially designed to produce biomass and known as energy crops. Although the biomass was traditionally used to ...

Recycling vegetable and animal wastes from households, livestock farms, vegetable farms, industry and timber processing, mushroom cultivation, and so on and using them for fertilizing vegetable crops in various forms (mixtures with organic and inorganic matter, compost and green fertilizer) is a permanent concern of researchers and farmers worldwide.In the glasshouse, it was studied influence of four types of compost (composted leaves, mixture of pieces of grape woods and tree branches, waste mushroom compost and ...

Drought and associated effects can cause serious damage to crop maize. Breeding drought tolerance by the development of new hybrids, aims at identifying some accurate screening techniques. The objective of this study was to evaluate the effect of the hydrological conditions (with stress - drought year and without stress - normal year) on the yield and other traits for six maize hybrids grown at ARDS ?imnic, Craiova and to investigate drought tolerance of these hybrids using several stress tolerance indices. Analys...

The paper presents the results from studies carried out in the farming conditions. It has been found that with the application of rational norms of mineral and organic fertilizers used for growing various crops (barley, rape, flax, soybean), soil fertility could be stabilized and their effectiveness enhanced. The content of mineral nitrogen under rape crops was at the level of the control variant. Its content in the variant using liquid manure (biofertilizer) was somewhat lower than that of in the rotted manure - ...
