  • Phytotoxic Effects of Jimsonweed (Datua stramonium L.) Seed Aqueous Extract on Seed Germination of some Cereal Crops Using Probit Analysis

   Several plants are phytotoxic in nature as they produce and release many chemical compounds into the environment. This study was carried out to investigate the phytotoxic effects of the seeds aqueous extract of Jimsonweed (Datua stramonium L.) on seed germination of sorghum (Sorghum bicolor [L.] Moench), millet (Pennisetum glaucum [L.] R. Br.), maize (Zea mays L.) and wheat (Triticum vulgare L.) using probit analysis. Laboratory experiments were carried out at the Faculty of Agricultural Sciences, University of Gezira, Sudan in season 2014/15. Ten concentrations (4.62, 9.26, 13.87, 18.51, 23.12, 27.74, 32.36, 36.98, 41.61 and 46.28 g/l) of the seeds aqueous extract of D. stramonium were prepared from the stock solution (100 g / l). A control with sterilized-distilled water was included for comparison. Treatments were arranged in completely randomized design with four replicates. The seeds were examined for inhibition (%) in germination at three days after initial germination. Data were transformed using Abbott’s formula and subjected to probit analysis (P £ 0.5). The seeds aqueous extract of D. stramonium inhibited the seed germination of the tested cereal crops and there was direct positive relationship between concentration (g/l) and inhibition (%). Also, the seeds of wheat (LC50 = 22.6 g/l) were most sensitive to the seeds aqueous extract of Jimsonweed followed by the seeds of sorghum (LC50 = 26.5 g/l) and maize (LC50 = 27.9 g/l). However, the extract was less toxic to the seeds of millet (LC50 = 32.2 g/l). It was concluded that that the aqueous extract of Jimsonweed (D. stramonium L.) was phytotoxic to the seed germination of the tested cereal crops.

  • EESRA: Energy Efficient Scalable Routing Algorithm for Wireless Sensor Networks

Many recent Wireless Sensor Network (WSN) routing protocols are enhancements to address specific issues with the “Low-Energy Adaptive Clustering Hierarchy” (LEACH) protocol. Since the performance of LEACH deteriorates sharply with increasing network size, the challenge for new WSN protocols is to extend the network lifespan while maintaining high scalability. This paper introduces an energy efficient clustering and hierarchical routing algorithm named Energy-Efficient Scalable Routing Algorithm (EESRA). The goal of the proposed algorithm is to extend the network lifespan despite an increase in network size. The algorithm adopts a three-layer hierarchy to minimize the cluster heads’ load and randomize the selection of cluster heads. Moreover, EESRA uses multi-hop transmissions for intra-cluster communications to implement a hybrid WSN MAC protocol. The paper compares EESRA against other WSN routing protocols in terms of network performance with respect to changes in the network size. Simulation results show that EESRA outperforms the benchmarked protocols in term of load balancing and energy efficiency on large scale WSNs.

  • Effects of alpha-tocopherol and some Medicinal Plants Seeds Powders on Broiler Performance
Abstract The aim of the study was to evaluate the effects of dietary inclusion of alpha-tocopherol and some medicinal plants seeds powders on broiler performance (Black seeds (BS), Fenugreek (FENS), Moringa (MORS), Clitoria (CLIS), Sunflower (SFS). During the finisher period one hundred and five one day old male broiler chicks (Ross308) strain were allocated into seven treatments. In a completely randomized design .The experimental treatments were as follows : Negative control (without additives ) ,200gm / kg alpha-tocopherol (positive control ) and five plants seeds powder in 5% level of inclusion (Black seeds (BS), Fenugreek (FENS), Moringa (MORS), Clitoria (CLIS) and Sunflower (SFS)).Each treatment was replicated three times with 5 birds each .During the entire experimental period the diets were formulated iso nitrogenous iso caloric to meet or exceed the broilers requirements . The chickens were divided in to equal groups, each group was subdivided into three group with 5 chicks each , in a Completely Randomized Design. The birds were fed a pre starter diet during the first week of age , then they received a balanced starter diet (24% crude protein and 3100 kcal metabolisable energy (ME)/kg) during the next 3 weeks .Then a finisher rations were offered during the last 3 weeks , the control group receiving diet based on iso nitrogenous iso caloric ration, and the experimental groups were fed ,the control diet supplemented with tested seeds powders at (5%) of the ration, and α-tocopherol tablets at (200mg/kg) of the ration. The birds were offered quantity of food and free access to water. Overall daily feed intake (ADFI), daily gain (ADG), and feed conversion ratio (FCR) were calculated. At the end of the experiment three birds from each treatment were slaughtered then Carcass weight percentage, and internal organs related to birds live weight was calculated . The results showed that ADFI, ADG, FCR shows a significant difference among the treatments, however BS treatment having the best FCR (1.99).While there was no drastic changes in the internal organs .
