  The aim of this study was to the economic assess of biological control  application approach in important date pests biological control. The model used in this research was Pemberton model. Based on the model findings and taking into account the net return on investment and total expenditure that carried out over a period of 18 years, the rate of returns on investment for biological control of spider mite the lesser, the and long horned beetle of date were 61.9, 29.4 and 16.8 respectively. The net profit to expense ratio for biological control of important pests was more than one, so that the bill of two pre-release periods (the first 9 years) and the post-release period (the second nine years) were estimated at 92.6, 35.2 and 22.5 trillion Rials were for Spider mite, the lesser moth and horned beetles, respectively. s. Economic factor is an important factor in the planning of biological control of date pests. According to the research results supporting biological pest control programs, and its successful implementation requires, knowledge managers, planners, investors and operators with economic benefits of investment in this area. From the perspective of economic experts is an important factor, according to the financial resources needed to support the elimination of pesticides to control pests biologically important dates assigned. The government can minimized the price risk of a date palm pest biological control agents by manufacturers guarantee to dates. Manuscript profile

  Efficiency is one of the indicators of economic performance evaluation and shows how the organization has used its resources in terms of production towards the best performance in a period of time. The purpose of this study was to Analysis of Production Boom Based on Economic and Social Performance (Case Study: Nano Motor oil company). Evaluation of Technical Efficiency of Nano Oils Several important indicators in this industry were measured before adding nanomaterials and after adding them, and their efficiency was evaluated according to the coefficients of importance of each of the indicators. In order to evaluate the economic efficiency of nano-oils, the performance of both products has been investigated according to their cost, and for assessing the social efficiency of nano-oils, the index has been used to reduce fuel consumption and reduce air pollution. The test method in this study is the method of comparing the paired data, given the importance of the coefficients. The results of the research indicate that the increase in the efficiency of the nano-motor oil in the case of using nanotechnology in the production process. By changing the technology and moving toward the nano-lubrication of the motor oil, with an increase of 55% of the finished product, the economic efficiency of the manufacturer was 4.89 The percentage of decline, the consumer economic efficiency increased by 40%, and the economic efficiency of the environment increased by 16%. Therefore, in accordance with the proposed social performance model, with the combined economic efficiency of the consumer, the consumer and the environment, it can be concluded that the social efficiency of nano-oils increased by 51.11% and could also boost production.

  8 - Comparative Analysis of Economic Efficiency between Low and High External Input Technology Agriculture in a Harsh Macroeconomic Environment of Imo State, Nigeria

  The study compared economic efficiency among smallholder farmers who practiced low external input technology [LEIT] and high external input technology [HEIT] agriculture in a harsh macroeconomic environment typified by inadequate fertilizer subsidy in Imo State, Nigeria More

  The study compared economic efficiency among smallholder farmers who practiced low external input technology [LEIT] and high external input technology [HEIT] agriculture in a harsh macroeconomic environment typified by inadequate fertilizer subsidy in Imo State, Nigeria. Cross sectional data generated from 160 smallholder farmers randomly selected from 2 out of the 3 agricultural zones in Imo State were used. Profit function was used in analyzing the data. Results showed that the LEIT farmers achieved higher level of economic efficiency relative to their HEIT counterparts, although the difference is statistically non significant. It is therefore recommended that in the face of escalating costs of fertilizer, organic manure could be used. Appropriate policies should be put in place by the government to encourage livestock rearing so as to effectively utilize their bye product-organic manure. Household refuse or bio-degradable from the cities could be channeled to farms to serve as organic manure. Manuscript profile

  In order to investigate the possibility of decreasing forage sorghum (Sorghum bicolor L. var speedfeed) water requirements applying of superabsorbent (SAP), without decreasing the dry matter yield and increasing the water use efficiency, and also to investigate the economic efficiency of applying superabsorbent (SAP), this experiment was conducted in Dashtak region of Zahedan during 2013 and 2014 seasons in a split-split plot with four irrigation regimes, providing 40, 60, 80 and 100% of the water requirements of sorghum, calculated from pan evaporation as main plots, four amounts of SAP )0, 75, 150 and 225 kg ha-1( as subplots and cutting as sub-subplots based on a completely randomized block design with three replications. The results indicated that the effect of irrigation regimes, SAP levels and their interaction effects of the two factors on dry matter yield, water use efficiency, and economic efficiency were significant. The regression models estimated showed that applying SAP in 100% ETc treatment had no effect on this trait but in the other irrigation treatments caused an increased the dry matter yield and water use efficiency. Therefore, applying 75 kg SAP per hectare along with 20% decrease in the sorghum’s water requirement in arid regions, the dry matter yield and water use efficiency is maintained similar to 100% sorghum’s water requirement. Also the greatest economic efficiency of applying SAP was secured at 75 kg SAP per hectare SAP level and 80% of sorghum’s water requirement. Manuscript profile
