This study was conducted to evaluate the effects of the different levels of chicken dung on the yield, and postharvest qualities of two genotypes of eggplant. The pot experiment was laid-out in a split plot randomized complete block design with chicken dung levels as the main plot and eggplant genotypes (Casino &Morena) as subplot. The levels of chicken dung were divided as T1 (zero), T2 (200 g/plant), T3 (400 g/plant), T4 (600 g/plant), T5 (800 g/plant), T6 (1.0 kg/ plant, and T7 (2.0 kg/ plant). Casino genotype produced higher yield than Morena genotype under Visca agro-climatic condition. The application of 400 grams of chicken dung per plant (T3) showed the highest yield in both genotypes which were significantly different from the control (T1), T2, T6, and T7. This simply means that a cost-effective application of chicken dung at 5 tons per hectare is worth recommending for optimum eggplant production. Casino has a higher oxidation-reduction potential and ascorbic acid values but with lower electrical conductivity than Morena hybrid. This means that Morena contains higher amount of electrolytes with better storability for a longer period of time but with lesser vitamin C content than the Casino genotypes. Ascorbic acid content and electrical conductivity were enhanced by the application of chicken dung which declined beyond 800 grams per plant or at an application of 10 tons per hectare particularly with Casino hybrid for ascorbic acid and Morena hybrid for electrical conductivity. All these results would indicate the importance of organic fertilizer application to attain highest yield with best postharvest qualities of eggplant.

This paper reports the fluorometric responses of photosynthetic microorganism consortium in the detection of heavy metals (Cu and Cd). The consortium was collected from natural water body, and then exposed to different concentration of heavy metals. The response was measured based on the fluorescence signal emitted by the consortium before and after the exposure to heavy metals, with excitation and emission wavelengths set at 526 nm and 648 nm respectively. Cell suspension with optical density (OD) of 0.75 at λ = 700 nm was found to produce best response. The ability of the consortium to respond to both heavy metals within 0.01 – 10.00 mg/L was confirmed. Thus, photosynthetic microorganism consortium could be a good natural candidate as heavy metals bioindicator.

With more than 40 percent of the world’s rubbish is burned, open burning is a significant source of atmospheric pollution globally and remains one of the main environmental issues and health concerns for many developing nations. Despite having stringent criminal penalties for illegal open burning, Malaysia encounters increasing trend in open burning incidents. A better understanding of the knowledge, attitudinal, and perception towards open burning would inform more effective intervention efforts towards changing this trend. A questionnaire survey to assess knowledge, attitude and practice of public was conducted in Kuala Terengganu. A total of 384 respondents from various demographic backgrounds participated in the survey. Descriptive analysis was used to analyse the respondents’ socio-demographic profiles. Pearson correlation was used to uncover the relationship between knowledge, attitude and practice among the respondents. Results showed that the respondents had good knowledge on open burning and showed positive attitude towards protecting the environment from the problem. However, they displayed lack of practice to tackle the problem in real life. The study also found a weak relationship between knowledge with attitude and practice on open burning. Policy-makers should, therefore, devise intervention programmes that can encourage higher practice rather than merely focusing on raising awareness.
