  Silkworm larvae when fed on leaves from mulberry (Morus laevigata) tree given soil treatment with 2 kg well rotten F Y M along with 0.2%N concentration consumed more food, gained significantly more weight and produced heavier cocoons, as compared to those fed on leaves from trees treated with 2kg FYM + 0.1%N, 2kg FYM + 0.3%N, 2kg FYM + 0.4 %N and 2kg FYM alone.

  The effects of NaCl stress on in vitro induced potato plantlets of variety of potato Solanum tuberosm L.) commercial variety cardinal was studied at Potato Research Center, Abbottabad, NWFP, Pakistan. Five NaCl treatments, each consisting of 0, 1, 2, 3 and 4% were used. Viability percentage, fresh weight of plantlet and height of plantlet was decreased by given range levels of NaCl. The effect of all treatments was very drastic on length of roots and number of roots per plantlet where no response was recorded. The treatment of 4% NaCl depressed all the parameters understudy. The results indicate that the variety "Cardinal" is not salt tolerant, even at 1% salt concentration.

  Calcium carbide is well known as a nitrification inhibitor and its role as a source of ethylene (C2H4), a potent plant growth regulator, is not thoroughly investigated. A pot trial was conducted to evaluate the effectiveness of formulated calcium carbide with different doses of nitrogen fertilizer on nitrogen use efficiency, growth and yield of wheat. At the 1st step calcium carbide was formulated with polyethylene and plaster of paris and named as Matrix-I (21% calcium carbide, 58% polyethylene and 21% plaster of paris). Wheat cv. Inqulab-91 seeds were sown in pots and 5 plants were maintained. Calcium carbide was applied @ 0, 7.5, 15 and 22.5 mg/kg pot soil with 0, 30 and 60 mg N/kg soil. It was noted that nitrogen fertilizer application significantly enhanced almost all growth and yield parameters of wheat. It was also observed that matrix-I not only improved growth and yield parameters of wheat except plant height, which was reduced by CaC2 application, but also enhanced N uptake by different plant parts of wheat, when applied @ 15 mg CaC2 kg-1 soil at 8 cm soil depth. It was further noted that matrix-I better improved N use efficiency when applied with half recommended dose of N fertilizer than that of with full recommended N fertilizer rate.

  In this study bacterial flora of meat in chicken Shawarma (meat) were investigated from five different regions of Lahore. Samples were taken from internal and external part of Shwarma. The contamination was present in both external and internal part of meat. But external part was found to be little more contaminated as compared to internal part. Analysis of microbes includes E. coli, Salmonella, Aerobes and Coliforms. Microbs were found in order of Aerobes > E. coli > Salmonella there is not too much variation of contamination in different regions but there is variation among the number of bacteria. In every part Aerobes were in greater number as compared to E. coli and Salmonella. Shawarma analyzed from the Site III was more contaminated as compared to other sites. The external part of the product showed more microbial load as compared to internal part.

  Weed-crop competition is a complex field of study. The extent of competition is governed by a number of factors including crop species, crop cultivar, crop density, weed species, weed density, the relative time of emergence of the crop and weed, the duration of the weed presence, the efficiency of weed control and soil and environmental factors. The greatest single cause of economic loss is, however, a reduction in yield due to weeds competing with the crop for available light, nutrients and moisture. The effect of Phalaris minor and Avena fatua on wheat was investigated at agronomic research area, College of Agriculture, Dera Ghazi Khan during 2007-2008. The experiment was laid out according to Randomized Complete Block Design (RCBD) having four replications and a net plot size of 5x2.5m. Plant density of 2, 4, 6 and 8 m-2 for Phalaris minor and Avena fatua was maintained. The data collected were analyzed using appropriate statistical techniques. Maximum plant density of wheat (96.500) was observed in T1 (control). All other parameters like total number of tillers (403.25), number of fertile tillers (400.25) and maximum plant height (86.750) was also observed in T1(control). Growth and yield parameters like number of spike lets/spike, number of grains/spike, 1000 grain weight, grain yield and biological yield showed significant response in the presence of Phalaris minor and Avena fatua under study. Maximum grain yield (7.0500 t/ha) was obtained in T1 (control) and T2 (6.8500 t/ha) and T6 (6.8750 t/ha), respectively. Maximum biological yield (14.875 t/ha) was obtained in T1control) and T2 (15.750 t/ha) and T6 (15.975 t/ha), respectively. It can be conclude from the current study that presence of weeds (Phalaris minor and Avena fatua) in wheat has remarkable adverse effect on the yield and its contributing factors. As the density increases, the crop performance is gradually declined.
