Eighteen (18) lactating she-camels and two mature male for mating were used to determine the effect of Management System on camel calving interval, The camels were maintained under semi-intensive (N = 9) and Traditional management system (N = 9) in North Kordofan State, western Sudan. The experimental females in each group kept together with the bull during 18 months. Blood samples were collected from jugular vein since 4-months post-partum and continue 14 successive months at monthly interval. The serum samples were separated and stored at -20°C and were analysed for progesterone concentration using progesterone specific radio immuno assay (RIA) kits. The results indicated that under semi-intensive system 77.8% of females had been pregnant in 5th - 8th month post-partum and the calving interval varying between 17 to 20 months. Under traditional system and during the experimental period 44.5% of females were pregnant in the 11th – 16th month and the calving interval varying between 23 to 28 months. The ratios of pregnant vs non-pregnant during experimental period in semi-intensive and traditional were 88.9% vs 11.1% and 44.5% vs 55.5%, respectively. Beside the behavioural signs progesterone level consider a good indicator for pregnancy in camels. In pregnant females Progesterone concentration increased significantly during early months. The range of Progesterone concentration varied between 1.10 – 5.76 ng/ml and 0.67 – 2.53 ng/ml in semi-intensive and traditional system, respectively. Our results allow quantifying this impact. With a supplemented diet including 2 Kg of concentrates and 5 kg of roughages per day, the fertility rate will be improved of 67%. It would be possible to expect more than two fold young camels in a year by supplemented 5 kg of concentrates. We conclude that under semi-intensive management dietary supplement during post-partum and early lactation period improves reproductive parameters for instance shortened calving interval.

The efficiency of chelated forms of trace minerals in poultry nutrition and the trace minerals requirements of poultry were discussed in this review. Trace minerals are essential for all farm animals, and these minerals, individually or together with other mineral, take part in many events such as metabolic activities, development and repair of different tissues, growth, immune and reproductive systems. In the last years, lots of studies related to different organic forms of trace minerals on the effects of broiler and laying hens were carried out. The results of these studies have showed that organic trace minerals added to poultry diets at lower levels than inorganic trace minerals are more efficient than inorganic trace minerals and they provide some advantages in poultry nutrition. One of the most important advantages is the reduction of mineral amount excreted in faces. In addition, the results of researches conducted especially in the last few years have shown that the chelated forms of trace minerals strengthen the poultry immune system, and increase the use of other nutrients. However, there are inconsistent between the effects of different forms of trace minerals used in poultry diets on the performance.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

Binary logit regression model of econometrics was used to identify the factors affecting adoption of recommended agricultural technology by the commercial farmers of Nepal. A survey was carried out in 2012 in 120 households from Kavre district, Nepal. The objective was to appraise factors affecting adoption of recommended technology of cauliflower, finding out the level of adoption, identifying the constraints of cauliflower cultivation, assessing the perceived level of satisfaction and studying the relationship of certain selected variables on the adoption. Education, Occupation, contact with Personal Localite sources of information, Group membership and Experience were the most influencing factors for adoption of recommended technology. Though, other factors were not strong enough to contribute significantly but indirectly influence the adoption decision of farmers as combined effects. Occupation was found as negatively associated. Landholding size was strongly and positively influencing among the non significant factors. The level of satisfaction and the constraints of cauliflower production were also identified. Transfer of technology will be effective if and only if the client adopts the technology. For an effective transfer of technology, it is better to go for activities for the welfare of the socioeconomic factors of the farmers.

Increasing of industrialization and population has resulted in the accumulation of a wide variety of chemicals. Especially, widespread use of synthetic and toxic chemicals have led to an effort to improve new technologies to reduce or eliminate these contaminants from the environment. Chemical methods that used for the treatment of toxic materials are expensive, time-consuming and difficult, especially in extensive agricultural areas. Furthermore these methods led to formation of new chemical pollutants. Recent years, one promising alternative treatment method is to use of microorganisms for the biodegradation of these toxic chemicals. This method is effective, minimally hazardous, economical, versatile and environment friendly. In this study, we thought that microflora of insecticide resistant insects may be a potential reservoir for the isolation of new bacteria that can be used for the biodegradation of insecticides. In this research work, totally 24 bacterial isolates capable of biodegradation α-endosulsan were isolated from the body microflora of insects belong to Orthoptera, Dermaptera, Mantodea and Hymenoptera orders. Based on the some morphological, physiological and biochemical characteristics and fatty acid profiles they were identified as Stenotrophomonas, Pseudomonas, Acinetobacter, Bacillus, Brevibacillus, Flavimonas and Rhodococcus. As a result, these isolates can be used for the treatment of α-endosulfan residues at different environments.
