The aim of this study was to select the best sources of auxin of which it can stimulate the growth of shoots Pineapple plant cuttings. This research is compiled in a completely randomized design (CRD) with 4 treatments and 6 replications. The Data were statistically Analyzed by the DMRT. Level of treatment given proves that no treatment 0%, cow urine concentration of 25%, young coconut water concentration of 25% and Rootone F 100 mg / cuttings. The results showed that cow urine concentrations of 25% and Rootone F 100 mg give the best results in stimulating the growth of shoots pineapple stem cuttings. Experimental results concluded that the effect of this natural hormone were better than the shoots without given hormone.

A propagation method is being developed that allows softwood shoots to be generated from stem sections of dormant woody plant species. These shoots, forced in the greenhouse during the winter, are subsequently collected and processed as softwood stem cuttings to produce clonal plant material. Many species in the nursery industry can only be propagated using softwood cuttings, and this technique allows propagation of these species to be initiated several months earlier than what is typically possible. Current studies involve expanded screening of ornamental tree and shrub species to determine if commercial production using this technique is feasible. Results demonstrate that many species may be propagated using this method, but that some species are more prolific than others with respect to number of softwood shoots produced. Additional studies are currently in progress to determine the environmental (light regime, moisture regime) and cultural (type of media) conditions that are optimal when producing clonal plant material via this technique.

Research studies were carried out to evaluate insecticidal action of two plant products and a synthetic insecticide on a major stored-product insect, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The plant species studied were, Piper nigrum and Eucalyptus camaldulensis, whereas methoprene used as synthetic insecticide. Two formulations viz., powder and ethanol extract of each plant and four concentrations (5ppm, 10ppm, 15ppm and 20 ppm) of methoprene were tested. Repellency was tested using the filter paper test whereas mortality, weight loss protection and anti-feedant potential of all treatments was evaluated by using whole maize grains. Our results were highly significant as compared to control however; P. nigrum was more effective as compared to E. camaldulensis. The investigation of cumulative effects of botanical and synthetic insecticide and isolation of active ingredients of botanicals are further issues to be investigated for their inclusion in. I. P. M programs.
