Factors of harvesting fruits and vegetables 1. Season Quality of produce are greatly influenced by season. e.g. Winter season harvest having more shelf life as compared to other season while …
Pre harvest factors affecting postharvest quality of fruits and vegetables a) Related to plants1.Crops: Quality of the fruit and vegetables are varies from crop to crop. e.g. jackfruit, bael, potato, onion, pumpkin, garlic etc. having good quality in relation to shelf life while apple, mango, cherry, strawberry, tomato, capsicum, okra, brussels sprout, chinese cabbage, carrot, radish attract more to consumers due to their attractive appearance. 2.Cultivars: The quality of seed or plant material is an important factor that controls the quality of the fruit and vegetable produced. Several parameters of quality are controlled genetically. 3. Cultural practices: All cultural practices have direct effect on the final quality of the produce. 4.Planting period: Many plants are very sensitive to environmental conditions and thus quality will not be optimized when crop is produced under adverse conditions. Producing summer plants during the winter or viceversa will not be appropriate, unless protection practices are implemented. 5.Planting density: It affects both the quantity and quality of the produce. High density planting increases competition between plants, reduces light availability, and thus may decrease quantity. Low density planting lead to large size, better colored fruit or vegetable which may have shorter shelf life. Larger fruits are commonly more sensitive to physiological disorders. 6.Irrigation: Irregular watering usually reduces fruit size, increases splitting, physiological disorders, reduces water content in the plant or plant part etc. 7.Fertilization: Poor management of fertilizers will increase physiological disorders due to deficiencies of some minerals or increase of other leading to toxicity. In both cases, quality will be negatively affected. The application of Ca and high fruit Ca concentration resulted in increased firmness, reduced disease incidence, chilling injury, physiological disorders and ripening and improved storaility. Application of excess N element is detrimental in terms of quality attributes. Pruning: It reduces the load and increases the growth of fruit and chemical use after harvest. …
