Preservative Solutions

Gladiolus is an important cut flower in the world, and its preference in Pakistan is next to roses. But the main problem that occurs in gladiolus is that it has short vase life. The present experiment was conducted with an objective to investigate the effect of four preservative solutions [distilled water, Sucrose (3%), AgNO3 (250 ppm), AgNO3 (250 ppm) + Sucrose (3%)] and packaging material on postharvest quality of three gladiolus varieties, “Tissue, White Prosperity and Alexandra”. Packaging material consists of control treatment (without packaging), packaging of cut spikes with 100 ppm acetic acid soaked cotton and packaging of polyethylene sheet after sucrose pulsing. The experiment was arranged as two factorial laid out according to completely randomized design (CRD) having three replications. Results showed that preservative solution having combination of AgNO3 (250 ppm) + Sucrose (3%) significantly improves days to open basal floret, floret opening percentage (%), bloom spread (inch), floret length (inch), floret diameter (inch), fresh spike weight (g), dry spike weight (g), fresh weight loss (%) and vase life (days). Moreover, this treatment was also effective in reducing the wilting (%) in all gladiolus varieties. However, for solution uptake (mL/spike) and solution balance (ml/spike), AgNO3 (250 ppm)alone gives the best results. For packaging treatment, the pulsing of a cut spike with 20% sucrose followed by polyethylene sheet wrapping proves to be effective. Among the varieties, Alexandra performed better for all quality parameters in comparison to White Prosperity and Tissue

The aim of this study was to find out the effect of different organic fertilizers on the population growth of Chydorus sp. This research was conducted at Laboratorium of Nutrition and Food Technology, Faculty of Fishery and Marine Sciences, Sam Ratulangi University, from December, 2012 to January, 2013. The experiment was run in the Completely Randomized Design with 3 treatments and 3 replication. Chydorus sp. was cultured in 9 glass jars with a volume of 1 L each. Three treatments applied in this research included A: medium culture composed of 500ml of water and 50 grams of soil; B: medium culture composed of 500ml of water, 50 grams of soil and 10g of cow dung; C: medium culture composed of 500ml of water, 50 grams of soil and 10g of horse dung. The density of Cydorus sp. in each media was 10 individuals /500 ml water. Observation on the population growth, development of live preys, and water quality parameters was conducted for 20 days period. Data were statistically analized with Analysis of variance. The results showed the highest density of Chydorus sp. was reached by Chydorus cultured in medium with horse manure (2169 individual/500 ml), followed by medium culture with cow manure (1715 individual/500 ml), and the lowest in medium culture with soil which was 1065,33 individual/500 ml. However, Analysis of variances showed that Chydorus population growth were not significantly affected by different culture medium. Keywords: manure, liquid fertilizer, growth, Chydorus sp.

The present research was conducted on two factor Completely Randomized Design (CRD) with eight treatments and three replications. A set of experiments were carried out to evaluate the effect of postharvest ethephon treatment and packaging on ripening of mango cv. Maldah. The treatments consisted of ripening agent i.e., ethephon and control treatment under different packaging condition i.e., fiber with hole, fiber without hole, plastic with hole and plastic without hole. The result revealed that different packaging condition and ripening agents influenced the ripening behavior of mango. The highest TSS (15.26), sugar-acid ratio (23.66) and juice content (126.05) were recorded with fiber (without hole) and the lowest TSS (12.60), sugar-acid ratio (9.01) and juice content (116.05) with plastic (without hole). The highest TA (1.44) was recorded with plastic (without hole) and the lowest (0.66) with fiber (without hole). Similarly, the highest BT (2.83) was recorded with fiber (with hole) and the lowest (1.66) with plastic (without hole). Firmness, sweetness, TSS and juice content were the highest with the interaction effect of fiber bag (without hole) and ethephon treatment. In conclusion, mango fruits with ethephon treatment packed in fiber bag (without hole) enhances quality and ripening of mango whereas under controlled condition and without hole plastic packaging mangoes had low quality performance in terms of physio-chemical properties.

ABSTRACT This study aimed to evaluate the effect of applying increasing doses of biofertilizer obtained by the anaerobic digestion of cassava effluent on the development of crambe plants. The experiment was conducted in a protected environment at the Federal University of Paraná (UFPR), Palotina Sector, between April and August 2015. A completely randomized design was used, and five different treatments with the following doses were applied in five replicates: 0, 40, 80, 120, and 160 kg ha-1 of K2O. The following parameters related to plant development were evaluated: final height, stem diameter, number of branches, dry shoot and root biomass, mass of the grains, and oil content. The 160 kg K2O ha-1 dose was found to have the best influence on the plant development, because all the measured parameters reached their highest values at this dose, except for oil content, which attained the highest percentage in the case of the control treatment (0 kg ha-1 of K2O). This study proved that the biofertilizer obtained by anaerobic digestion of cassava effluent can be used as an alternative to regular fertilizers in cultivating crambe.

ABSTRACT Methionine is an essential amino acid, and generally, the first limiting one in the diets of tambaqui, the main native fish produced in continental aquaculture in South America. However, there is a lack of information on their amino acid requirement, especially for maintenance and efficiency of utilization. The present study aimed to determine the requirement of [methionine plus cystine] for the maintenance and efficiency of utilization using tambaqui of different body weights. Two experiments were carried out using 250 tambaqui with weights of 100 and 300 g. They were distributed in a completely randomized design with four treatment groups (0.264, 0.396, 0.528, and 0.660% of digestible [Met + Cys]), five replications. The control treatment (CT) was performed with the addition of methionine at the first level (0.264%) until the second level was reached (0.396%). The maintenance requirement was determined by the regression analysis between the consumption of [Met + Cys] and protein retention equal to zero. The efficiency was determined using the value of the slope coefficient of the line obtained by the linear regression. The protein and methionine retention values of tambaqui weighing 100 to 300 g were compared by the parallelism test, and no difference was observed between the parameters of the equations indicating the need for only one equation to describe the responses to body weights. The requirement of digestible [Met + Cys] for the maintenance of tambaqui with weights from 100 to 300 g was 60.47 mg kg-0.7 day-1 and the efficiency of utilization of 42%.

This research aims to determine the effect of fine bubble technology with different pressures on Siamese catfish seed's growth and feed efficiency in an aquaponic system. This research used a completely randomized design with four treatments and three replications. Treatment A (Control), Treatment B (FBs with a pressure of 4.5 atm), Treatment C (FBs with a pressure of 5 atm and treatment D (FBs with a pressure of 5.5 atm). The parameters observed were Specific Growth Rate, Feed Conversion Ratio, water quality (temperature, pH, DO, and ammonia), and plant productivity.  The seeds used were catfish seeds aged 16-36 days, 1-2 inches long, and weighed 0.26-0.29 grams. The container used is a fiber tub of 16 units with a size of 70 cm x 70cm x 70 cm. The feed used is commercial feed PF 1000 content crude protein 35%. The data were analyzed using variance with the F test at the 95% confidence level. The best treatment for catfish growth was treatment D (pressure 5.5 atm), which gave the highest SGR value of 7.24 ± 0.5 and FCR value of 1.19 ± 0.09. The value of water quality parameters is in suitable condition for the growth of catfish seed. The best plant productivity was found in treatment D with an average weight of 60.75 g.
