Regulations of new CAP reforms moving from product to producer support and now to a more land based approach. This is in response to the challenges facing the sector, many of which are driven by factors that are external to agriculture. These have been identified as economic, environmental and territorial. To achieve these long-term goals, the existing CAP instruments had to be adapted. The reform therefore focused on the operational objectives of delivering more effective policy instruments, designed to improve the competitiveness of the agricultural sector and its sustainability over the long term. Accordingly there is a great need to restructure the formal crop rotation and to introduce new alternative crops as food industrial crops and vegetables. Both cases have high invested special asset and manual work requirement. This paper as a case study gives an analysis of oil pumpkin seed production, which serves as an example of economic and technological planning a formal crop production farm over 100 hectares. The new crop was introduced as a possibility to face with diversification under the new CAP regime of greening. The economic analysis covers five years of production and financial data on the basis of the given crop rotation.

Supercritical fluid chromatographic (SFC) separations of a-tocopheryl acetate, α-, ß-, y- and -tocopherol have been achieved on a Spherisorb S3 ODS2 column in about 15 minutes. Separation efficiency of this method has been optimised with respect to the effect of pressure, percent of methanol in the mobile phase, temperature and flow rate, resulting in theoretical plate numbers (N) varying from 63000 to 90000 per metre. Linear correlations have been found between log k' (retention factor) and fluid density for all of the tested compounds, and a van't Hoff plot yielded linear correlation between log k' and T-1 at constant mobile phase density. Linearity and repeatability were found to be acceptable with detection limits from approximately 20 ng for α-, ß-, y- and ő-tocopherol to 10 ng for a-tocopheryl acetate at a signal to noise ratio = 3. Results obtained by use of the developed SFC method to determination of tocopherols in plant oils obtained by SFE (supercritical fluid extraction) and by aqueous enzymatic processing are presented.

Studies concerning the removal of oil from model wastewater using the hybrid process combining ultrafiltration and nanofiltration were performed. The separation and transport characteristics of the employed membranes were determined. The content of oil in wastewater was estimated by the determination of total organic carbon and oil concentration measurements using a Horiba OCMA-310. The investigations of oil wastewater treatment were carried out in two stages. The permeate obtained from the UF process (the first stage) generally contains less than 6 mg/dm3 of oil, whereas in the NF process (the second stage) the complete removal of oil was achieved.

The carried out investigations evaluated ovicidal activity of mahlab, Prunus mahaleb L. kernel oil against cotton leafworm, Spodoptera littoralis (Boisd.). The chemical constituents of the fixed oil of mahlab were analyzed using gas-liquid chromatography (GLC). Timnodonic (33.07%), oleic (28.71%) and linoleic (24.35%) were the basic fatty acids, while the major hydrocarbon and sterol were found to be heneicosane (62.57%) and β-sitosterol (10.57%). The LC50 values for the one-day-old egg masses were found to be more susceptible than 3-day-old ones. Moreover, the leaf dip technique occurred to be more efficient than spraying technique. The results also showed abnormalities in the external morphology of egg shell, chorion surface, shell imprints and aeropyles of S. littoralis eggs treated with mahlab and KZ oils as compared to a control by using scanning electron microscope. Generally, the tested oils significantly reduced the activities of transaminase enzymes (AST and ALT), acid and alkaline phosphatases and total soluble protein except mahlab oil on acid phosphatase as compared to a control. Additionally, the oils of both mahlab and KZ oil affected some biological aspects such as incubation period, larval duration, larval mortality and pupal weight comparing to a control.
