Energy Optimization of Traditional and Modern Farms of Broiler Production using Data Envelopment Analysis Approach
The main objectives of this study were to analyze the energy efficiency of broiler production of Mazandaran province in north of Iran based on traditional and modern farms. For these purposes the data envelopment analysis (DEA) approach was applied to the data on energy use in broiler production in individual farms. The results indicated that the percentage of efficient units were founded about 17% and 34% in technical (CCR model) and pure technical (BCC model) for both systems. Also, about 17% of total units of traditional and modern farms had the efficient score fore scale efficiency index. Based on CCR and BCC models of DEA, the average of technical, pure technical and scale efficiency scores of traditional farms was calculated as 0.837, 0.927 and 0.906, respectively; while the modern farms results indicated that technical, pure technical and scale efficiency scores was founded as 0.873, 0.978 and 0.892, respectively. The total saving energy of traditional and modern farms was about 19907 and 6740 MJ 1000 birds-1, respectively. Accordingly, it can be said, comparing to present farms, the total energy requirement of DEA method decreased as 11.16% and 3.57% for traditional and modern farms, respectively. The last part of this research illustrated that diesel fuel, feed and electrical energy had the highest share for total saving energy by the DEA method in both systems of broiler production.

The administration of FADAMA and agricultural sector performance in Nigeria
Agriculture was the mainstay of the Nigerian economy before the discovery of oil in commercial quantity in the late 1960s to early 1970s. The sector provides employment opportunity for a larger portion of the nation’s population. So also is the provision of raw materials for most industries and provision of food for the nation. With the discovery of oil in the country, the sector has been witnessing decline in terms of performance. This has prompted the government in the early 1990s to establish fadama among many other measures aim at alleviating the problem facing agriculture. This study therefore examines the impact of fadama administration on the performance of agricultural sector in Nigeria. The study adopted qualitative analysis by comparing agricultural sector’s performance pre and post fadama establishment. The findings show mixed fortune in the performance of the sector. Whereas the total agricultural production has been on the increase, it has not been enough to meet the domestic consumption as the nation still import some agricultural products especially food items. Also the contribution of the sector to GDP is declining much as labour mobility from the sector to more lucrative sector is becoming rampant. The study therefore concludes that more funding be allocated to fadama in particular and the entire sector in general so as to address the problems detected by the findings.

Field bindweed, Convolvulus arvensis: A new host plant recorded to Tuta absoluta in Egypt
Although the Solanaceae family leaves (tomato, eggplant, potato,…etc.) is a main host plant for the larvae of tomato leafminer, Tuta absoluta; field bindweed, Convolvulus arvensis is recorded as a new host plant to tomato leafminer, T. absoluta as a first time in Egypt. The larvae of T. absoluta were attacked the leaves of C. arvensis completely. This finding confirmed that the tomato leafminer is a polyphagous insect. This allows it to survive in many habitats in the absence of Solanaceae family crops. This result recommended that removing of field bindweed plants from tomato field may be reducing the tomato leafworm population.

Influence of growth media on early growth and development of yam seed
ABSTRACT Suitability of growing media or substrates is essential for production of quality seedlings for transplant. It directly affects the development and later maintenance of the extensive functional system. A good growing medium would provide sufficient anchorage of support to plant, serves a reservoir for nutrient and water, allow oxygen diffusion to the root and permit gaseous exchange between the root and atmosphere outside the root substrate. In the present of study different growth media were used to germinate the seed of white yam (Dioscorea rotundata) under a controlled growth chamber to identify which among the tried media is best for yam seed. The growth media tested were Cocopeat, Peat pellet, Carbonized rice husk, Top soil, Cocopeat + Top soil and Carbonized rice husk + Top soil. Each treatment was measured into a nursery seedling basket, arranged in randomized complete block design, and replicated four times. Daily minimum and maximum Temperature and Relative humidity records were recorded throughout the experiment. At 60 and 90 days after seed sowing, growth response parameters were recorded and were subjected to analysis of variance and treatment means were separated using least significant difference at 5% probability level. Highest germination of 71.65 and 88.65% at 60 and 90 days after sowing respectively were recorded from yam seed planted in Cocopeat and the same trend was observed in respect of growth response parameters observed. Top soil had the least influence as growth medium, which was not significantly different from response from its mixture with other growth media.

Some Physical and Engineering Properties of Persian Shallot (Allium hirtifolium Boiss.)
Persian shallot grows as a wild plant in some mountains of Iran. Persian shallot, a bulb producing plant from Alliaceae, is a wildly growing plant collected for its bulbs. Bulbs of Persian shallot, called “Mooseer” in Farsi, are oval, white skinned, usually of one and rarely of two main bulbs and are completely different from common shallot (Allium ascalonicum). In this study, various physical properties of Persian shallot were determined at a moisture content of 68.62% w.b. The equatorial diameters, polar diameters, shape index, volume and density were 36.647 ±3.30 mm, 33.242 ± 3.47 mm, 1.0898 ± 0.07, 3.5106 ± 0.961 cm3 and 5211.292 ± 1108.463 Kg.m-3, respectively. The static coefficient of friction was obtained on the plywood surface followed by the glass and the galvanized iron sheet surfaces. The shear strength increased with an increase in loading rate. Linear model for describing the mass of Persian shallot, by applying dimensional characteristics and volume was investigated. The results showed that mass modeling of Persian shallot based on oblate spheroid shaped volume (Vosp) and geometric mean diameter (Dgm) are the most appropriate models, respectively.

Economic and social values of family poultry production and its constraints in Ethiopia
Although Ethiopia has large number of chickens, their productivity is marginal and constrained by genetic, environmental and management factors. This paper has tried to review the socio-economic contribution of rural poultry production and its constraints in Ethiopia. Indigenous chickens account for about 98% of the total poultry population. The productive and reproductive performance of the local chickens is very poor with an average egg yield of 30-60 eggs/hen and 6 months age at first lay. To improve the livelihood of rural communities by improving the productivity of poultry, development endeavors and research institution should focus on introducing improved breeds along with full packages and investigating on means of improving the local genotype. Keywords: Chicken, extension, egg, gender
