Cadmium(Cd) has been proven to affect plant growth and development. Experiment was therefore, conducted to examine the influence of Cd on aromatic rice cultivars at tillering stage. The experiment was arranged in a randomized complete block design comprising three different aromatic rice cultivars (Meixiangzhan 2, Xiangyaxiangzhan and Guixiangzhan) and three Cd levels (0, 50 and 100 mg/kg -1 soil). Antioxidant enzymes (Superoxide dismutase (SOD), Peroxidase(POD), and Catalase(CAT)), osmolyte accumulation (proline, protein, total sugar, amino acid), lipid peroxidation (in terms of melanodialdehyde(MDA)) and growth parameters (plant height, and total dry matter content) and Cd uptake in rice cultivars exposed to different Cd levels were examined. The results showed that, with increased levels of soil Cd toxicity, activities of SOD and MDA contents increased, while activities of POD and CAT enzymes, as well as osmolyte accumulation and dry matter contents decreased for all cultivars. Cd uptake in roots and in shoots of all the cultivars increased with increased soil Cd contents. Uptake was higher in roots than in shoots with Meixiangzhan 2 showing the highest uptake in both roots and shoots followed by Xiangyaxiangzhan and Guixiangzhan cultivars. The results suggested that soil Cd toxicity have negative consequences on rice growth. Rice roots accumulated higher Cd than shoots and uptake varies amongst cultivars. Conclusively, Cd toxicity impaired early growth in rice by affecting physio-biochemical attributes, however, Guixiangzhan variety performed better than the other two varieties.

Stem rust (Pucciniagraministritici) is a disease of economic importance in wheat (Triticumaestivum L.) worldwide. The objective of this study was to determine the disease severity of the BC1F1 plants in the nursery at Kenya Agricultural and Livestock Research Organization, Njoro. Kingbird (resistant) was crossed with Njoro Bw2 (susceptible) to obtain F1 plants. The F1plantswere backcrossed with Njoro Bw2 to obtain a BC1F1 progeny. Two hundred and forty seeds of the BC1F1 plants, twenty eight resistant and susceptible parents were planted in two replicates and the Modified Cobb’s Scale was used to record their disease severity scores. An excel work sheet programmed with the AUDPC formula was used to compute the Area Under Disease Progress Curve (AUDPC) values for BC1F1 plants. Variation of the disease severity scores and mean AUDPC among the wheat plants was analysed using Analysis of variance (ANOVA). Results showed 47.9% ofresistant plants that portrayed the pseudo black chaff (PBC) trait had low disease severity mean scores ranging from 0 to 1.0414 with mean AUDPC values below 99.8. The resistant plants without PBC were 43.3 % and had disease severity mean score ranging from 0.9098 to 1.3686 with mean AUDPC values ranging from 99.8 to 260.The BC1F1 plants that showed susceptibility to stem rust disease were 21 (8.8 %) and had the highest disease severity mean score ranging from 1.3223 to 1.4914 with the highest mean AUDPC values ranging from 282.5 to 431.3. The ANOVA computation showed that, variation in the disease severity and in the mean AUDPC values among the individual plants (P < 0.001) was significant, but variation in mean AUDPC values from one replicate to another (P > 0.001) was not significant. The BC1F1 wheat plants showed a low disease severity score in the field indicating that these plants received the APR genes for stem rust and this could be useful for wheat improvement through breeding.

Alirajpur district in Madhya Pradesh is one of the important areas with great potential for onion production. In district Alirajpur, onion is grown in an area of 1370 hectares with a production of 20550 tonnes, with a maximum productivity of 15.00 tonnes per hectare. It was found that the majority of the farmers are still lagging behind the adoption of improved onion production technology in the area. It thus, becomes necessary to assess the adoption behaviour of onion growers, towards improved onion production technology therefore the 130 farmers were selected using proportionate allocation method from small, medium and large farmers. This study depicted that majority of the onion growers 37.69 per cent were found to have medium adoption behaviour of overall technology followed by high adoption behaviour 36.15 per cent and low adoption behaviour 26.15 per cent in respect of overall onion production technology respectively

A total of 72 fishes, belonging to three species of order perciform fish: Acanthopagrus bifasciatus (Sparidae), Platax orbicularis and P. teira (Ephipidae), which were collected from Iraqi marine waters, during period October 2013 till July 2014. The results showed tow species of monogenean: Sprostoniella multitestis and Lamellodiscus sp. The study included the prevalence and intensity of fish parasites, where there appeared clear differences in respect to fish species, and showed significant differences at p≤ 0.05. The present study revealed that the highest prevalence (92.85%) of infection in P. teira and mean intensity (25.57) of infection in A. bifasciatus and showed the lowest prevalence (78.43%) in A. bifasciatus and mean intensity (9.33) in P. orbicularis. Significant (p≤ 0.05) differences were noticed in the infection of male (34) and female (25) fish with the parasite. Infection with these monogenean in general showed monthly variation, as it was high during November and January and low during December and June.

Small ruminants are associated with the rural poor. They play a big role in supporting the livelihood system of the poorest men and women livestock keepers, especially in the marginalised areas. Sheep and goat marketing in India is highly unorganized. The general features of sheep and goat marketing are those markets are locally known as hat/animal fair/shandi conduct weekly or bi-weekly at village, block or town and city level. The study is conducted in Tumakuru, Chitradurga, Belagavi and Kalaburagi districts of Karnataka. Total sample size of 60 market intermediaries were chosen. The technique of logit regression is used to know the factors determining sale price of sheep and goat. The results of the study revealed that, per animal marketing cost incurred by sheep and goat farmers was 106.64. The farmers realized less than 82 per cent of the price paid by the butcher and wholesaler. However, the magnitude of price spread in channel-IV (17.18%), channel-II (18.45%) and channel-I (18.45%) were found to be higher than that of channel-III (8.40%). Consequently, the proportion of costs and margins of intermediaries in respective channel were considerably higher than that of channel-III, mainly due to only involvement of local trader between farmer seller and farmer buyer. The physical characteristics namely, body weight, breed, sex were influenced significantly on sale price of goat and sheep. The other factors, existence of large number of buyers in the market, festivals and season were also influenced.

This study was carried out at the Poultry Research Station belong to state Board of Agricultural Research, Ministry of Agriculture, Abu Ghraib. The duration of this study was from 28 November 2013 to 15 May 2014 to evaluate the effect of supplementation different levels of organic selenium(Se-yeast) and inorganic selenium (Selenium selenite) on some productive performances of broiler breeder and selenium levels in plasma ,egg (yolk,albumin). The study included 336 female broiler breeder and 28 males (Ross 308 and arbor acres), 42 weeks old were randomly distributed to 7 dietary treatments experiment with 2 replicates / treatment (24 females and 2 male birds /replicate). The duration of the experiment was 24 weeks, and treatments were as the following: C (Control diet) without supplement, T1, T2 and T3 Supplementing with (Se-yeast) (0.2, 0.4 and 0.6 %) respectively and T4, T5 and T6 with (Selenium selenite) (0.2, 0.4 and 0.6 %) respectively. The results recorded a significant increase in hen day egg production (HD%) and egg weight (g) for the treatments T2(Seyeast)and T5(Selenium selenite) respectively. however, the results showed no significant differences for egg mass (g), feed conversion ratio (FCR) and eggs available for hatching (%). Also, the results appeared that there were no significant differences (P<0.05) between different sources and levels of selenium on its concentration in blood plasma. Nevertheless, the total concentrations of selenium for egg yolk and albumin were significantly higher for T3 treatment which enrolled 12.16 μg/ egg compared with control group and T4, which recorded 10.12 and 10.45 μg/ egg, respectively. Therefore, it was concluded that adding different levels and sources of Se had a significant effect on some productive performance, while organic selenium was more deposited in the internal egg components.

A laboratory study was carried out to; (1) identify the efficient primer(s) which be used to detect alleles,(2) estimate the degree of diversity among the studied genotypes, and (3) determinate the suitable genotypes which show high degree of diversity in order to improve the economic characters for the local genotypes. The present study was conduct at Nebraska University/ Field Crop & Horticulture Department during summer season 2013. Ten selected simple sequence repeat (SSR) marker sets were evaluated in a total of sixteen accessions of bread wheat (Triticum aestivum), twelve of which have been introduced from Mexico, two from USA and two are local genotypes (Latifya and Ibah 95).All the 10 markers were polymorphic and produced 45 alleles (average 4.5). The gmw480marker had the higher percentage of frequency, whilexgwm132 and gmw32 markers had the lowest percentage of frequency, therefore they showed high efficient in categorizing the genotypes studied. The PIC values were 0.32 for gmw480 and 0.99 for xgwm132 & gmw32markers (average 0.86). The dissimilarity coefficient (diversity) ranged between 0.20.99(average 0.80). The highest dissimilarity coefficient for the introduced genotypes was 0.97 for BW49398 genotype while the lowest value was 0.71 for CW15-6732 genotype.
