Irradiation alone or combined with other alternative treatments to control postharvest diseases

  The postharvest diseases are considered worldwide as the most significant issue for postharvest facilities. Although there are various methods to decrease postharvest losses, consumers are looking for agricultural product free of chemicals. It is therefore necessary to develop alternatives to synthetic chemical control to reduce environmental risks and raise consumer confidence. Several alternatives such...

Distribution and size structure of comb jellyfish, Mnemiopsis leidyi (Ctenophora) in the southwestern Caspian Sea

  Temporal and vertical distributions of Mnemiopsis leidyi were studied along three transects namely Lisar, Anzali and Sephidrood in the southwestern Caspian Sea during 2001 to 2010. The maximum lengths of the ctenophore were 60 to 70 mm, and bulk of individuals (90.6%) were <5 mm in length. The means of abundance and biomass during the whole period were 3032 ind/m2 and 293.54 g/m2,...

Effect of stabilizers on the quality of carbonated flavoured whey drink

  Carbonated Flavoured Whey Dink (CFWD) was prepared by blending sugar (8%), stabilizers (that is, carboxy methyl cellulose, carrageenan), colour and flavor (orange red) to liquid whey. The whey drink was subjected to carbonation. The whey drink was evaluated for their physico-chemical and sensory properties till 30 days of refrigerated (4°C) storage. The storage study revealed that fat, lactose, SNF, total...

Effects of leaf harvest on crude protein and mineral contents of selected early maturing lines of lablab (Lablab purpureus)

  The crude protein and mineral elements of the tropical legume Lablab purpureus leaves were determined in eight different lines to evaluate the effect of leaf harvest on the contents of crude protein and mineral elements. Leaves of the eight lablab lines were harvested at 6, 8 and 10 weeks after planting (WAP) for the study. The crude protein and mineral contents were found to be higher at the...

Prospects of clonal selection for enhancing productivity in Saffron (Crocus sativus L.)

  Saffron a member of Iridaceae family is a perennial spice species. It is derived from the stigma of the flower of the saffron crocus (Crocus sativus L.), which is collected and dried to produce the spice. The main compounds that accumulated throughout stigma development in C. sativus L.  were crocetin, its glucoside derivatives and picrocrocin, all of which increased as stigmas...

Spatial variability in soil properties of a continuously cultivated land

  Poor knowledge of soil suitability for agricultural production constitutes a major problem to land users. For proper assessment of the distribution soil properties, the use of geographic information system (GIS) has been considered a very effective tool to achieve this. A study on an Alfisol at the Institute of Agricultural Research and Training, Ibadan (7°23êž‹N, 3° 51êž‹E), Nigeria, was carried out...

In vitro evaluation of antitrypanosomal and cytotoxic activities of soil actinobacteria isolated from Malaysian forest

  A total of 83 actinobacteria isolates were successfully revived from cryovials stored in -80°C FRIM actinobacteria culture collection (FACC). Based on macromorphological observation, Streptomyces-like group is predominant among all the isolates. The representative actinobacteria isolates were grown in three different fermentation media (M1, M2 and M3) and a total of 249 culture broth extracts...
