Haematological and serum biochemical parameters are indicators of physiological, nutritional and pathological status of animals. Investigation of these parameters provide information for diagnostic purposes. The study was conducted to determine the influence of feeding graded levels of yam peel meal (YPM) as a replacement for maize on haematology; blood chemistry was evaluated in rabbits. Thirty- six (New Zealand white X Chinchilla) were randomly assigned to four dietary treatments in a completely randomized design with nine rabbits per treatment. The rabbits were fed diets containing 0, 12.5, 25 and 37.5% of Yam peel meal (YPM) as a replacement for maize, designated as T1, T2, T3 and T4, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were randomly selected for hematological and serum biochemical analysis. All the haematological and serum biochemical indices except AST were affected (P<0.05) by dietary inclusion of YPM. Although most of the parameters investigated were affected by rabbits fed test ingredient, the values fell within the normal literature reference values for rabbits. It can therefore be concluded that up to 37.5% inclusion level of YPM can be fed to growing rabbits without deleterious effects on health status.

The number of studies on edible coatings that are used for extending the shelf life of fruits has steadily increased. For this purpose, it is necessary to choose raw materials with characteristics that maintain product quality. The objective of this study is to evaluate the effect of coatings of Chlorella sp. on the post-harvest conservation of ‘Tommy Atkins’ mango fruits. The experiment was conducted using a completely randomized design, and spray treatments (T) with 0%, 1%, 2%, 3%, or 4% of Chlorella sp. were applied to the fruits. After the treatments, the fruits were stored for 28 days (21 days at 10 °C and 42% relative humidity and 7 days at 25 °C and 42% relative humidity), and were analyzed on day 28. There was higher pulp firmness in fruits as the concentration of Chlorella sp. was increased, and the concentration of ascorbic acid was comparatively higher (22.17%) in fruits treated with 3% Chlorella sp. The percentage of soluble solids and the soluble solids/titratable acidity ratio were decreased as the coating concentrations were decreased. The use of Chlorella sp. at 1% and 2% allowed fruit maturation without compromising fruit quality attributes during the 28-day storage period.

This study aimed to estimate plastochron, leaf area, and yield of Physalis peruviana seedlings grown in different environments and transplanted on different dates. The experiment was carried out in a completely randomized design, arranged in a 2 x 3 factorial scheme, namely: two cultivation environments (protected and field) and three transplanting dates (10/27/2013, 12/15/2013, and 02/11/2014). Four replicates of eight plants were used per plot, and the four central plants composed the useful area. Based on mathematical models and temperature data, plastochron was estimated for the entire crop cycle and vegetative and reproductive phases separately. Leaf area and node number were measured, and their relationship established at the end of the study. Other variables assessed were fruit number, mass, and yield per plant. Our results showed that the higher temperatures in the protected environment anticipated phenological timings. Plastochron values of 60.0 and 16.5 °C day-1 can be used during vegetative and reproductive stages, respectively. The protected environment increased vegetative growth and development, as well as yield of P. peruviana seedlings. In the Guarapuava-PR region, P. peruviana seedlings should be transplanted during the spring so that higher fruit yield and quality could be achieved.

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

The main objective of the study was to standardize enrichment of aonla pulp to develop fruit bars. The experiment was laid out in Completely Randomized Design (CRD) with 10 treatments. Aonla pulp was blended with 25 to 75% of different fruit (mango, papaya and jackfruit) pulp viz. Aonla pulp, Aonla with mango, papaya and jackfruit in different proportion of 3:1, 1:1 and 1:3 each fruit respectively. The initial moisture content was higher in aonlapulp enriched with mango pulp in 1:3 proportions. Enrichment of aonlapulp with fruit pulp of mango, papaya and jackfruit reduced the ascorbic acid, titratable acidity and tannin content of the resultant fruit bars compared to that from pure aonla pulp, which is an indication in the reduction of astringency. Enrichment also resulted in an increase in total soluble solids, reducing, non-reducing and total sugars of the resultant fruit bars. Enrichment of aonla pulp with fruit pulp of provitamin A rich fruits like mango, papaya and jackfruit showed a rise in total carote-noids and reduced astringency and acidity, thereby resulting in fruit bars with altered palatability and enhanced nutrition. Enriched fruit bars contained three vital antioxidants viz. Vitamin C, carotenoids and polyphenols of all the treatments, enriched fruit bar containing 25 % aonlaand 75 % mango (T4) was found superior in organoleptic evaluation.
