Muhammad, Aslam (2004) IMPACT OF DIFFERENT NUTRITIONAL SOURCES ON VARIOUS DEVELOPMENTAL AND PRODUCTIVE POTENTIALS OF SILKWORM, BOMBYX MORI L. PhD thesis, University of Agriculture, Faisalabad.
1.These investigations were INITIATED WITH a lot of laboratory reared, Pakistani strain of Bombyx mori L., larvae, raised on the leaves of Morus laevigata L., mulberry crop, fortified with 9 different mix ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ ups of some mineral sources, (Ts), in three ways (Ms), from the top, through the stem as well as from the soil, giving equal importance to the Ts and Ms, the trials were laid out in a Factorial Experiment under Completely Randomized Design. 2.For this purpose, the project, was split into four almost independent But interrelated sections. The FIRST of these, dealt with the preliminaries on the introduction, review of literature,materials and methods etc. of the dissertation, in a general way, before splitting it further into subsidiary sections. The SECOND and THIRD dealt with the source impact, on exclusively, on the developmental and biological aspects of the Bombyx mori L. as affected by the Ts and Ms. Along with what happened, exclusively, with this source impact, on the productive potential and various characteristics of the silk filament. Finally, however, the information from the preceding two sections, was pooled together, in section four, and a cumulative impact of the nutritional packages on the developmental and productive potentials etc. of the Bombyx mori L. discussed in a general way, with reference to the work of previous scientists, who used nutrients other than, exclusively, minerals, as reviewed in the first section. 3.To wind up, of course, it was finally concluded: that; The influence of various mix-ups of the optimum doses of micro-elements, tested, on 25 different parameters of B. Mori L,life via the mulberry leaves, varied not only with the Ts, but also with the Ms as well as with the TsxMs. The various mineral-induced changes in the silkworm life, were, ultimately, indexed in form of an increase of the quantitum as well as the qualitum of silk ÃÂÃÂ¢ÃÂÃÂÃÂÃÂproduce. The changes, in silk ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ produce, due to the mineral supplementation, was found to be 88.80% or the maximum in Ts and finally, that; These were mainly determined through the changes in empty cocoon weight.
