Tomatoes, also referred to as poor man orange, are a great source of antioxidants; Vitamin K and C, which are beneficial to the health of the human being, play a significant role in processes industries. This review article aims to highlight the uptake of mineral nutrients from foliar fertilization of tomato for its growth and developmental responses of various cells and tissue. It holds several health assistances, including urinary tract infection, skin problems, diabetes, hypertension, and various cancers. Despite several kinds of research conducted on many characteristics of foliar fertilization while many are still unknown. In tomato, foliar fertilization is the most effective method compared to soil nutrient availability, which is low, topsoil dry, and root activity during the reproductive stage is decreased. Foliar fertilization is also successful in increasing the content of the fruit, yield, and the potential for the developmental process. It is anticipated that the foliar fertilizer should be recommended in the integrated tomato production. It provides a link between the treatment of micro and macronutrients and helpful in boosting productivity leading to quality of tomato crop and environment friendly. This review article discusses the effect of various nutrients, methods, and applications on the quality and quantity of tomatoes. In addition, their effects on the vegetative and reproductive stages of tomatoes are also discussed.

The significance of grapefruit is laying in its unique medicinal values and health related compounds. This article discusses the influence of seasonal variations and storage periods on the synthesis and accumulation of new polyphenolic compounds, terpenes, flavonoids and sugars profiling of grapefruit (Citrus paradisi) cv. shamber juice were evaluated under advance techniques. The individual sugar profiling of (total sugar, fructose, glucose and sucrose) individual phenolic acids and essential groups of terpene compounds measured at five harvesting times, from early to late stages and compare to storage days of (0, 15, 30, 35, 45 and 65). The higher contents of flavonoids were obtained in December harvested fruits while in comparison the 45 and 65 days the contents were reduced however in others days the contents were maintained the higher contents of Limonene, Quercetin, Perillyl alcohol and Monoterpenes were measured in December harvested fruits the 35 day of storage periods showed the constant contents of terpenes and little reduction of terepene at 45 and 65 days of storage. It may conclude that the mid date was best for good health fruits while the all of these compounds were present in higher amount at 35 day of storage.

Purpose the objective of study to modified the metabolism of Calendula officinalis L. under heat stress couple with N and P application in two years of study. Methods the trail was conducted during peak summer season (months of May, June, and July) couple with different levels of N & P application to monitor the quality and quantity characterization of marigold (Calendula officinalis L.). The traits of three doses of N and P (0.6 g, 0.9 g, and 0.8 g, 1− 1 g) given to Calendula officinalis L.) to display the vegetative, reproductive, physiological parameters such as Malondialdehyde (MDA), Chlorophyll contents, Lipid Peroxidation Assay in leaves, Li and K contents, phytochemicals and nitrogen and phosphorus used efficacy Results showed that maximum values of Malondialdehyde (MDA), Chlorophylls, Lipid Peroxidation Assay in leaves observed followed by the alteration in Li and K measured in the month of May, June with slight differences July. The phytochemicals like total phenolic contents (84.41 mg GAE/g), total antioxidants (36.3% DPPH), total carotenoids and total flavonoids contents (16.2 and 0.9 mg/100 g) were measured by 0.9 g of Nitrogen application and followed by 1 g of Phosphorus in both years of study. The respirational changes were observed in the higher rate of P levels. The liner changes of N and P rates showed some fluctuation in heat stress months. Conclusions It was concluded that the higher doses of both N and P fertilizers were effective in controlling the heat stress and mentioned the quality of florets by various induction and biological active process.

A study was planned to ensure the post-harvest quality of apple during storage periods through natural plant resources instead of using chemicals. Melia azedarach (Dharek) and Azadirachta indica (Neem) is well known as rich resources of bioactive compounds with antioxidants potential, used to maintain the quality of apple fruit and to avoid decay during storage periods. The pure compounds were isolated and used in films with the concentration of (30mg Ditriterpenoids and Secomeliacins films) and applied to apples, were purchased from the local market of Haripur Pakistan. The three main quality enzymes like superoxide dismutase (SOD), catalase (CAT), and proximate (POX,) were measured in stored fruits. Moreover, total phenolic compounds (TPC) and TA found retained during the storage period under (30 mg triterpenoids and Secomeliacins) film treatments. The HPLC-DAD analysis of stored fruits and fresh apple fruits showed the presence of five bioactive compounds with a minor variation for 9 days of storage periods. The phytochemical screening of treated fruits during the storage period showed the eight important bioactive compounds when compared with fresh fruits. It was concluded that new active films were helpful to used (Diterpenoids + Secomeliacins) are effective in maintaining the fruit quality during storage periods. The protocol and development of film’s with their engineering trails of thickness, water vapour permeability measurement in active films are discussed in the relevant section of this article to maintain the postharvest quality of apple fruits during storage periods as films are used in future green technologies in chemicals and food industry.
