Drought stress restricts the growth of okra (Abelmoschus esculentus L.) primarily by disrupting its physiological and biochemical functions. This study evaluated the role of Ascophyllum nodosum extract (ANE) in improving the drought tolerance of okra. Drought stress (3 days (control), 6 days (mild stress), and 9 days (severe stress)) and 4 doses of ANE (0, 0.1%, 0.2%, and 0.3%) were imposed after 30 days of cultivation. The results indicate that drought stress decreases the chlorophyll content (total chlorophyll, chlorophyll a, chlorophyll b, and carotenoid) but increases the activity of anthocyanin, proline, and antioxidant enzymes such as ascorbate peroxidase (APX), peroxidase (POD), and catalase (CAT). Physiological and biochemical plant disturbances and visible growth reduction in okra under drought stress were significantly decreased by the application of ANE foliar spray. ANE spray (0.3%) significantly increased the chlorophyll abundance and activity of anthocyanin, proline, and antioxidants (APX, POD, and CAT). ANE regulated and improved biochemical and physiological functions in okra under both drought and control conditions. The results of the current study show that ANE foliar spray may improve the growth performance of okra and result in the development of drought tolerance in okra.

The present research was carried out to assess raw milk's quality as collected from the commercial markets of the Mardan district (Khyber Pakhtunkhwa). The locality from which milk samples were collected included; Bijligar (BG), Manga (M), Chamthara (CM), Main Bazar Mardan (MB), Mahidherai (MD), and Sharif Abad (SB), located in district Mardan, Khyber Pakhtunkhwa (KP). A total of 36 milk samples were collected at the rate of 6 samples per location. The outcome of the data exhibited that the percentage of protein content was highest (3.34%) in MB and SA (3.30%), while lower percentages were recorded in sample M (3.03%) and CM 93.06%). Maximum pH were shown in M and BG to be 7.55 and 7.33, respectively. For fats content, the highest percentage of fats was witnessed in MB as 4.04%, and minimum fats content was noted in Sample M as 3.57%. Water content was highest in Sample SA and BG at 15.85% and 15.64%, respectively. Qualitative analysis of adulterants like detergents, Formalin, starch, and Hydrogen peroxide was also carried out for all the collected samples. Adulteration results were positive for all the milk samples, with the highest being in samples MB (30%), while all the remaining samples had adulteration at 20% each. Both MB and CM samples were adulterated with urea, while the remaining 4 were adulterated with neutralizers. Thus, it may be summarized from the whole analysis that the milk available in commercial markets of district Mardan was adulterated with different adulterants and is not recommended for consumption.

Plant extracts represent a rich repository of metabolites with antioxidant and antimicrobial properties. Neem (Azadirachta indica) is a medicinal plant considered the tree of the 21st century. In this study, we investigated the antioxidant and antimicrobial effects of propyl disulfide (PD), a major volatile compound in neem seed, against the pericarp browning (BI), microbial decay incidence (DI), and water loss of longan fruit. Fresh longan cv. Shixia samples were packaged in oriented polypropylene (OPP) and polyethene (PE) packages of different thicknesses (20, 40, and 60 µm). Sterile gauze was fixed inside the packages and 500 uL of PD was placed on them to avoid the direct contact of PD with fruit samples. Packages were sealed immediately to minimize vaporization and stored at 12 ± 1 °C for 18 days. Fruit samples packaged in open net packages served as controls. The results showed that fruit treated with PD in OPP and PE packages significantly prevented losses of water, DI, and BI compared to control treatment. PD also maintained the color, TSS values, TA values, pH values, high peel firmness, high TPC content, and high TFC content, and reduced the activity levels of PPO and POD. Scanning electron microscope (SEM) analysis indicated that the exocarp, mesocarp, and endocarp of longan peel were smooth, uniform, and compact with no free space compared to control, where crakes, a damaged and loose structure, and a lot of fungal mycelia were found. The shortest shelf life of 9 days was observed in control as compared to 18 days in OPP-20 and OPP-40; 15 days in OPP-60, PE-20, and PE-40; and 12 days in PE-60 packaging films. Therefore, PD as a natural antioxidant and antimicrobial agent, in combination with OPP-20 and OPP-40 polymeric films, could successfully be applied commercially to extend the postharvest shelf life of longan.

India and China, two emerging economic and nuclear powers and the most populous countries in the world, are already together making more than one third of the world’s total population. China and India have disputed 125,000 square kilometers border since 1950s, which is generally divided into three sectors: The largest eastern sector which is under Indian control. The middle and smallest sector where control is divided between both the states. (Svensson, 2012) Despite of sharing a long border between China and India, there is no mutually agreed Line of Actual Control (LAC). After India’s independence, it was expected that both the nations will come together to develop Asia but unfortunately the Tibetan Issue and its annexation by China in 1950 caused some differences. With increasing tension in conflict, every attempt in peaceful negotiation failed and diplomatic relations were freeze till 1976. In 1954, the joint ideas of Panchsheel were introduced by Indian Prime Minister and Chinese Prime Minister but the provision of Asylum to Lie Lama by India annoyed China in 1959. In 1962, both the states got involved in border conflict in Arunachal Pradesh and Ladakh. The relations got strained when China invaded the territory of India. Since then both the superpowers couldn’t find any possible diplomatic solution to the border conflict. (Ayres, 2020) Ladakh region of India which borders China and Pakistan serves as the world’s only “Nuclear Trijunction”. (Aamir and Ahmad, 2020)
