Poor soil fertility due to continuous depletion of micronutrients is a major problem for the production of Prunus domestica L. Low level of soil organic matter and calcareous parent material decrease the bioavailability of these micronutrients to plum plants. Thus, less micronutrients uptake resulted in deterioration of plum fruit quality and decreased yield. On the other hand, balance and correct combination of micronutrients used as a foliar has potential to overcome this problem. Foliar application method provides plants a chance for rapid and easy uptake of micronutrients. Therefore, the present research was carried out to select the best combination of micronu-trients using foliar method. Aim of the study was to select a balanced combination of micronutrients for better production and improved quality of plum (Prunus domestica L., variety Fazal manai) fruit. Seven treatments in three replications were applied. Our results showed that the quality of fruit was significantly improved through the application of T6 micronutrients consortia. A significant increase in total soluble solids (16%), fruit yield per tree (92%) and fruit size (12%) validated the effectiveness of treatment T6 (Zn + Cu + Fe + Mn + B = 0.5% + 0.2% + 0.5% + 0.5% + 0.1%) over control. Application of treatment T6 also enhanced quality attributes, that is, juice acid-ity (22%), juice sugar (22%) and juice contents (16%), as compared to control. It is concluded that use of treatment T6 as a foliar application is a better approach for significant improvement in quality and yield attributes of plum in micronutrients deficient conditions.
ResearchPage 3 ABSTRACTThe present study was carried out to investigate the effect of different drying methods on the physicochemical composition and organoleptic characteristics of dehydrated apricot fruits. The fresh apricot was dehydrated in open sun and in moveable solar drier developed by Pakistan Council of Scientific and Industrial Research (PCSIR) Skardu. The chemical composition showed that the fresh apricots contained moisture 83.3%, ash 0.72%, crude fat 0.03%, crude Protein 0.9%, crude fiber 1.02% and carbohydrates 14.03%. The moveable solar drier and using open sun drying substantially decreased moisture content to 14.61% and 15.7% respectively. Proportions of other components were increased, which include ash (3.51% and 3.43%), crude fat (1.99% and 1.82%), crude protein (1.0% and 0.97%), crude fiber (2.98% and 2.95%) and carbohydrates (75.91% and 75.13%). Organoleptic characteristics of open sun dried apricot has a little negative effect on over all acceptability when compared to moveable solar dehydrated apricot, however the open sun dried method was declared acceptable by the panel of judges for color, taste and overall acceptability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
