The Effect of Foliar Fertilizer on the Growth and Leaf Yield of Mulberry
Fermin O. Bayeng Jr.
Abstract
The response of mulberry applied with three foliar fertilizers (Complesal, Crop Giant and Peters Professional) were determined. Results of the study revealed that the difference foliar fertilizers significantly differ on their effects on height increment but did not differ on their effects on the final height, total leaf and average number of nodes per sample plant. Peters Professional effected the highest height increment followed by Crop Giant and Complesal.

Abstract
The case of a small provinced-based handweaving company demonstrated the strategy of the government through the Philippine Textile Research Institute (PTRI) in assisting the development of small and medium enterprise (SMEs).
The enterprise adopted the PTRI developed technologies on handloom weaving and dyeing using natural dyes. From an initial facility consisting of 3 units of 2-harness and piña/silk fabrics in 1995, it now employs 87 weaver producing at least 2,500 yds/month of plain or with designs piña and piña/silk fabrics.

Abstract
The extended storage of hybrid bivoltine silkworm eggs at 5oC after the termination of diapause was studied to determine its effect on the hatchability and rearing performance and to ascertain its storage duration at 5oC after the termination of its diapause and remain viable. The study tested 5 chilling periods; 2, 8, 9, 10, 11, and 12 months cold storage. It utilized a total of 1,800 JC102 hybrid silkworm eggs subjected to varying cold storage duration. The eggs were hatched and reared until cocoon formation for assessment. The 12 economic parameters employed prove that hybrid bivoltine silkworm eggs can remain stored at 5oC and relative humidity of 80 to 85% up to 11 months from egg laying or 9 months from the termination of diapause with minimal adverse effect. But on account of cocoon productivity, the study showed that hybrid silkworm eggs should be maintained in cold storage up to 9 months from egg laying or about 7 months from the termination of diapause. Further chilling of eggs up to 12 months proved detrimental.

Abstract
The garments and textile industry in the Philippines was reviewed with emphasis on the small and medium enterprises (SMEs). The paper presented the technological development of the SMEs in the garments and textile sector. The government support to the SMEs was also discussed giving emphasis on the role of the Department of Science and Technology (DOST) and the Philippine Textile Research Institute (PTRI) which is the only government agency that is mandated to conduct research and development projects for the textile industry sector, render technical services and provide training program. The paper also reflected the investment opportunities and competitive advantage of the industry, its strength, policy environment for SMEs, and financing. Finally, the paper discussed on promoting SMEs business linkages and partnerships internally and externally

Abstract
The study was conducted to identify the physical characteristics of mulberry leaves of different mulberry varieties grown at PTRI-TC, La Trinidad, Benguet. It aimed to establish ground information and basis for more studies on the morphology of mulberry for future selection and breeding purpose
Six Local and five foreign varieties were studied. The parameters for leaf description used were the color of matured leaf, leaf shape, leaf tip, leaf base, leaf margin and leaf texture.
Varietal differences were observed on the leaves of 11 different mulberry varieties. The leaf features alone though, are insufficient basis for varietal identification. The close similarities of the leaf characteristics are confusing and misleading especially to the beginner's eye. Nonetheless, the result of the study using leaf features for mulberry varietal description can be a take off point for other related studies particularly on the nomenclature of existing varieties in the country.
