Ex-ante regulations and ex-post liabilities for using a new technology will induce additional costs for adopters. The standard model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible cost reductions. The case analysed is...

The importance of soybeans derives from the multiple uses in the human nutrition, animal feeding, industry, but also as a plant that improves the physical properties of the soil by improving the soil in nitrogen. Regardless of the use of practical cultures, for obtaining high yield in terms of...

The paper presents the results of research conducted under the conditions of Turda Agricultural Research and Development Station (ARDS Turda) located in the hill area of Transylvania, regarding the influence of the soil tillage system (CS - plow, MC - minimum chisel, MD - minimum disk and NT -...

The formation of the spring barley crop is influenced by the variety chosen in the culture, the pedo-climatic conditions, the precursor plant and the applied technology. Experiences carried out at SCDA Turda in 2019 and 2020 have shown that spring barley grown in no-tillage technology responds...

This paper aims to address the problem of achieving soybean production and how technological factors influence the realization of production. Was choosing the most efficient technological variants of crop. We compared in the experiment realized at ARDS Turda how the two systems works: classic...

Production data registered at winter wheat Ariesan cultivar in 2007-2017 period, indicates suitability for cultivation in system with no ploughing, the difference in production between the two systems classic and conservative is just 81 kg/ha thus, in the classic system the average yield was...

The purpose of this paper is to evaluate the soybean yield obtained from the application of the additional fertilization and economic efficiency determination. Experimental factors: Factor A - the fertilization: a1-N20P20K0 (100 kg/ha), applied simultaneously with sowing, a2-N20P20K0 (100...

The purpose of this paper is to evaluate the soybean yield obtained from the application of the minimum tillage system compared to the classical tillage system. Conservative tillage systems have become an important part of agriculture, and the need to apply these systems is justified by the...

In order to clarify some aspects of the spring barley reaction on the production and accumulation of the protein in grain, at different levels of fertilization, some estimates of this chemical component were made at 16 levels of fertilization with N: P: K in the period 2016-2017. The increase in...

Through the experiment realized at ARDS Turda in 2007, was monitored in comparativ, the evolution the soil under the influence of the tillage system, the crop plant, and the level of fertilization. Increasing the reserve in the macro-elements is much more significant in the case of the...
