Abstract: An experiment was conducted to compare the growth and conformation of male Teddy kids (3 months age), under two management systems during the year 2014. The kids were kept at the livestock experimental station, Department of Livestock Management, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University Tandojam. A total of twelve (12) Teddy kids were randomly divided into two groups i.e. A and B having six kids each. The kids of group A were reared under semi intensive management system (concentrates and open grazing) whereas kids of group B were kept under intensive management system (concentrates and green fodder). The duration of the experiment was eight (8) weeks and the observations for growth and conformation traits (girth, height and length) were recorded on weekly basis. The result revealed that the average body weight of kids in group A (8.29 kg) had significantly higher (P<0.05) than B (7.75 kg). Moreover, the average body conformation in respect of girth, height and length of group A kids (48.17cm, 40.5 cm and 39 cm respectively), were significantly higher (P<0.05) than the kids in group B (47.5 cm, 39.33 cm and 37.67 cm respectively). While comparing the economic aspects of kids reared under two management systems, it was noted that more net profit (Rs. 337 /kid) was earned from the kids of group A as compared to the kids of group B (Rs. 245 /kid). In conclusion, the kids reared under semi intensive management system demonstrated better performance in terms of body weight and conformation traits which were more profitable.

Abstract: The pot study was conducted during autumn 2015 at Department of Soil Science, Sindh Agriculture University, Tandojam Pakistan to assess the effect of soil applied potassium sulphate (K2SO4) fertilizer on growth, biomass production and K accumulation of plants of tomato variety Roma. The study was executed in a net-house under natural conditions following completely randomized design. There were six treatments (0, 50, 100, 150, 200 and 250 kg K2O ha-1), each repeated thrice. A recommended blanket dose of 150 kg nitrogen and 75 kg phosphorus ha-1 was also given to the crop. Tomato plants were raised in five kg plastic pots filled with a K-deficient soil (119 mg kg-1). Results of the study indicated that K nutrition significantly enhanced growth, biomass production and K accumulation of tomato plants. K nutrition augmented different plant height (49%), shoot diameter (103%), fresh biomass (134%), dry biomass (182%), number of leaves (75%) and K concentration (3.1 fold). It is concluded that a dose of 100 kg K2O ha-1 was the most optimum for tomato plants at early growth stage. These results need to be verified under field conditions at maturity level of tomatoes.

Abstract: The study was conducted to determine the population fluctuation of red flour beetle Tribolium castaneum on different dry fruits under laboratory conditions from 6th March 2015 to 24th July 2015. Four different dry fruits viz; T1 (almonds), T2 (walnuts), T3 (peanuts), T4 (cashew nuts) and T5 (wheat as control) were used in the experiment. The standard weight of 50g of every dry fruit was kept in plastic jars and covered with muslin cloth. Ten pairs of beetles were released in each jar. Observations were recorded at fortnight interval and population of the live beetles was counted. Results of the study showed that the population of red flour beetles gradually increased in all the treatments control with respect to time. The highest overall mean population of T. castaneum was recorded in wheat (61.61±10.02) followed by cashew nuts (52.90±8.26), almonds (50.01±7.81) and walnuts (43.56±5.89). The lowest population of red flour beetles (27.41±8.26) was recorded in peanut. The highest weight loss was recorded in wheat (18.8 %), followed by cashew nuts (15.6%), almonds (14%), walnuts (11.2%) and peanuts (8%) respectively.

Abstract : Synthesis and Characterization of Zinc Oxide Nanoparticles for Antibacterial Applications

Abstract: ZnO nanoparticles are synthesized for antibacterial applications by a simple co-precipitation method. X-ray diffraction (XRD) reveals that the synthesized ZnO has hexagonal crystal structure with mean crystallite size of 29 nm. Scanning electron microscopy (SEM) and Energy dispersive x-ray spectroscopy (EDX) shows pure ZnO with uniform morphology. UV–VIS absorption spectroscopy yield an absorption edge in the range 300-400 nm which corresponds to a band gap energy of 3.50 eV. Antibacterial activity of ZnO nanoparticles is tested against gram positive and gram negative bacteria by using agar-well method. These ZnO nanoparticles are found to be strongly antimicrobial as they effectively prevent the growth of many test microorganisms with a small minimum inhibitory concentrations (MIC) ~ 80 – 280 µg/ml.
