Aims: This study aimed at enriching the ensilaged quality and nutrient contents of whole-plant water hyacinths (WWH) based silages in different recipes. Study Design: Twelve recipes with three replications each were assigned in a completely random design. Place and Duration of Study: Faculty of Science and Agricultural Technology, Rajamangala University of Technology Lanna, Lampang Campus, Thailand, between October 2018 and September 2019. Methodology: Treatments were twelve recipes including: T1= light wilted WWH+ 1.96% salt,  T2 = light wilted WWH + 4.15% molasses + 8.27% rice bran, T3 = light wilted  WWH + 6.63% molasses + 15.86% rice bran, T4 = light wilted WWH +8.91% molasses + 22.83% rice bran, T5 = moderate wilted WWH + 1.59% Salt, T6 = moderate WWH + 11.17% molasses + 13.33% rice bran, T7 = moderate wilted WWH + 10.75 % molasses + 25.67% rice bran, T8 = moderate wilted WWH + 10.36% molasses + 37.11% rice bran, T9 = extremely wilted WWH + 1.16% salt, T10 = extremely wilted WWH + 5.10% rice bran, T11 = extremely wilted WWH + 4.30% molasses, T12 = extremely wilted WWH + 4.30% molasses + 5.14% rice bran. Each recipe was mixed into triplicates of a 30 kg high-density polyethylene plastic bag under anaerobic condition for 30 days. Results: The results demonstrated that T6, T7, and T8 were quite superior in fermentation characteristics; T3, T4, T6, T7, and T8 were judged outstanding in physical assessment; T4, T6, T7, and T8 were more appropriate in terms of nutritive values. Conclusion: This work demonstrated that WWH can be upgraded into high-quality silage by wilting, chopping into pieces, adding rice bran and molasses, and ensilaged for about 30 days. The finding from this study indicated that T6, T7, and T8 were fit all aspects and recommended as recipes for producing high-quality WWH-based silage for ruminants.

Food handler still fails to play their part even when the government imposes “No Plastic Bag” campaign and a ban on polystyrene foam to pack foods. This research focuses on eco-friendly food packaging based on the perception and practice of young consumers, especially the undergraduates of Mara University of Technology Penang Campus (UiTMPP). Questionnaire was constructed and distributed to 315 respondents.  The collected data were analyzed with simple descriptive statistic of frequency, mean and standard deviation. Most of the respondents are aware on eco-friendlyfood packaging. They agreed that the university should propose some alternative to control and reduce non-biodegradable foods packaging.

The Impact

One of the important aspects in the implementation of new products for production in the open field is the assessment of the impact of environmental conditions on their operation. Typically thermo-climatic research is carried out for such project. The laboratory of Techno-climatic Research and Heavy Duty Machines of Cracow University of Technology, equipped with a large-sized thermo-climatic chamber conducts this type of research. Bearing in mind the assurance of high quality of the conducted research, the quality management system (QMS) was developed and implemented. The article describes the requirements, scope and process of obtaining a Polish Centre for Accreditation (PCA) certificate.

The nutrient uptake and growth rates of the water lettuce [Pisitia stratiotes] were investigated in a batch culture system and a continuous flow system. As the water hyacinth [Eichhornia crassipes] is well known and widely researched as an aquatic macrophyte, water hyacinths were used as a control in a batch culture system. It was found that the specific growth rate of water lettuce was slightly higher in dry season, and in rainy season the growth rate of water hyacinths decreased almost 70%, but the rate of water lettuce decreased only 45%. From this result, water lettuce is thought to be grow up enough even under low solar radiation. The nitrogen, phosphorus and ash contents of biomass were about 1.5 times higher in water hyacinths than in water lettuce (N:2.15% & 1.65%, P:1.67% & 1.03%, ash 19.6% & 19.9% respectively). As the biomass of water lettuce is not so big and heavy (wet weight of water lettuce was under 100g and the width and height of the plant was under 20cm), removal of surplus biomass from water bodies is easy. It was made clear that water lettuce is very effective for removing nutrient from water bodies.

Sterility in wheat in parts of the subtropics has been linked primarily with low-boron soils and its variability between years and locations with variation in the weather. This paper shows, from reciprocal transfers of plants between adequate and zero boron root media at different developmental stages, that the period during which florets are sterilised by boron insufficiency can be very short. For any ear it extends from after its flag leaf tip has emerged until shortly after the flag leaf has become fully expanded. This critical period of up to 1 week in length has already passed when the ear begins to emerge. Because tillers are sequential, the critical stage for the whole plant is longer than 1 week. It was shown that ears could also be sterilised by enclosing the whole plant in a clear plastic bag during this critical period, even though the plants were growing with adequate boron provided in sub-irrigated gravel culture. It is suggested that one of the effects of enclosure is to prevent transpiration and possibly the associated uptake and movement of boron to the reproductive growth centres. The six genotypes tested did not differ in the developmental stage at which they were sensitive, and all were completely sterile when they were grown without boron up to and including that stage. However, it appeared that a prior period in adequate boron had a different effect on sterility amongst genotypes. One genotype (Fang 60) showed evidence of a boron reserve that could be utilised even after a period equivalent to 3 phyllochrons whereas others appeared to have no boron pool. Ears which were fully sterilised by inadequate boron could have their fertility raised marginally by a spray of boric acid even several days after they had emerged. The implications of these results to grain yield in the subtropics are discussed.
