Chrysanthemum (Dendrathema grandiflora Tzvelev) is an Asteraceae family, very popular ornamental plant in the family, generally characterized by aromatic, deeply lobed, alternate leaves and often large and showy flowers. The main problems in chrysanthemum business is Thrips sp. This pest can attack chrysanthemum plants in all plant growth stadia, but the most harmful attacks occur in early formation phase. Thrips pest control recommendations on chrysanthemums have been provided by various authorized agencies, including through the use of resistant varieties. This study aimed to determine the effectiveness of various bio-pesticides and microbial pesticides. The study was conducted using a randomized block design with 5 replications. The experimental unit consists of 1 m2 land-plot, and each plot is planted with 100 stool with 10 x 10 cm space. Results indicated that the Neem seed, Annona muricata, and Tinospora crispa extract as biopesticides, effectively controlled the total population of Thrips nympa and adult, but has no significant different on the extracts level between three plant species on Thrips population density. The microbial pesticide (Beuveria sp.,) Jatropha curca leaf extract, Mentha cordifolia leaves, were less effective in controlling the Thrips population, although it was better than the Thrips population in control.

Subsidies allocation represents an important source of financing the agricultural enterprises, being analyzed by the scientists from all over the World. The subsidy policy of the Republic of Moldova is different from the subsidy policy of the European Union, being determined by the following factors: the lack of the consistency of the subsidies policies from the Republic of Moldova and the insufficiency of the necessary financial resources in order to apply the policies like in the European Union. Strategically, at the state level, it doesn’t exist a clear subsidy policy for a longer period of time, namely the subsidies measures are not very clear defined and are changing from year to year, which creates difficulties for agricultural producers to access subsidies. In this context this scientific research has the objective to analyze the subsidies effects on competitiveness of the agricultural enterprises, to analyze the subsidies allocated in Moldova compared to neighbor countries, to reveal the measures of subsidizing the agricultural enterprises and to find out if the enterprises can achieve higher competitiveness by subsidies allocation.

In Romania, the value of added tax (VAT) is the most important source of revenue for the general consolidated budget (24.4% in 2015 and 23.1% in 2016), but the degree of compliance is around 80% VAT paid on time in relation to the VAT declared in VAT returns submitted by taxable persons registered for VAT purposes. The paper presents the impact of the measure split VAT payment on insolvent agricultural companies, as it has the role of increasing the voluntary compliance rate of companies in insolvency, reducing VAT evasion, ensuring a fair competitive environment by eliminating the advantages of some economic operators with incorrect fiscal behaviour that does not pay VAT to the state budget. The conclusions drawn from the study revealed that the split VAT measure would reduce the chances of recovery for insolvent agricultural companies, contradicts the payment schedule and the prioritization for the distribution to creditors and contravenes the objective for which insolvency proceedings were regulated.

The structure of rural human resources (from agriculture, industry, constructions) represents the most important production factor in order to achieve economic growth (high GDP). In terms of efficiency, it is more important to assess the way in which the combination of human resources between these three branches contributes to GDP formation. To do this assessment for the period 2013-20120, we applied the nonparametric method of DEA (Data Envelopment Analysis). This method enables ranking regions based on a series of inputs (rural population occupied in agriculture, industry and constructions) and outputs (rural gross domestic product). The data regarding the rural human resources are retrieved from the Amigo data base, the rural GDP Eurostat and the analysis was performed by MAXDATA 6.3 Beta program. The results revealed that, by 2020, if maintaining the 2006-2013 trends, the average technical efficiency will decrease by 5.4%, only the Central and the South-West regions will be performing well and the North-East and North-West regions will become more inefficient. Our results reveal that, in the majority of regions, there is a clear need to reduce the population from agriculture, to increase the population from industry and constructions, and to increase de productivity, to ensure real economic growth.

Field crop residues have become an urgent problem for the Egyptian farmer. Total cultivated area with this crop in Egypt, 189,000 hectare and the estimated quantity of haulm potatoes is about 1,575 Tg with an average of 8.3 Mg/hectare of haulm potato. Varied techniques were used for cutting waste of field crop, and the mechanical shredder residue for handling and use of these wastes were analyzed in order to reduce the size of the waste molecules to fit the various aspects of its uses. To optimize the operating parameters of the performance of farm residues it was used the cutting machine and it was established the minimum cost, power and energy requirements for produce animal feed raw materials from potato haulme. The performance of the machine units was measured under the following parameters four levels of drum speed of 25.13, 30.14, 35.17 and 40.19 m/s (1,000, 1,200, 1,400, and 1,600 rpm), three feed rates of 600, 800, 1000 kg/h, two number of knives on the cutting cylinder from (68 to 48). The performance of the cutting machine unite was taking into consideration machinery productivity, percentages of softness degree, cutting efficiency, fuel consumption, power, energy, and cost analysis. The optimum results and parameters for cutting machine untie when using drum speed 1,600 rpm, 1,000 kg /h feeding rates, and 68 number of knives.0.985 Mg/h productivity, 19,123 kW power, 19,414 kW.h/Mg energy, 6,046 l/h fuel consumption, 99 % cutting efficiency, 85% percentages of softness degree, and 9,850 l.E/h cost analysis.
