ABSTRACT-Fruits and vegetables are the important source in human life. It should be safe and consists of good shelf life which can improve the level of consumption of fruits and vegetable among the society. The processing is such a great parameter which analyses the quality of food. Today fruits and vegetables are susceptible to the growth of microorganism which may be air borne, soil borne and water borne disease. Enzymes offer potential for many exciting applications for the improvement of foods. There is still, however, a long way to go in realizing this potential. Economic factors i.e. achievement of the optimum yields and efficient recovery of desired protein are the main deterrents in the use of enzymes. Changing values in society with respect to recombinant DNA & protein engineering technologies and the growing need to explore all alternative food sources may in time make enzyme applications more attractive to the food industry
The nutrient elements which are required comparatively in small quantities are called as micro or minor nutrients or trace elements. Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. Proper plant nutrition is essential for successful production of vegetable crops. Integrated supply of micronutrients with macronutrients in adequate amount and suitable proportions is one of the most important factors that control the plant growth in vegetable crops. Micronutrients which are essential for all higher plants are boron (B), chlorine (Cl), copper (Cu), iron (Fe), zinc (Zn), manganese (Mn), molybdenum (Mo) and nickel (Ni). Micronutrients like Cl, Cu, Fe and Mn are involved in various photosynthetic processes and Zn, Cu, Fe and Mn are associated with various enzymatic activities, Mo is specific for nitrate reductase only. Boron is associated with the carbohydrate metabolism and reproductive phase of the plants along with photosynthesis or enzymatic activities. Judicious use of micronutrients is essential for vegetable cultivation to get maximum yield of high quality produce. Plants differ in their need for micronutrients. In this review, we focus on the major functions of mineral micronutrients in vegetable production.
Coriander (Coriandrum sativum L) is an annual herb that belongs to the family Apiaceae (Umbelliferae) and is commonly known as dhanya. For centuries, the coriander plants and their parts, primarily their leaves and ripe seeds, have been used in folk medicines in addition to culinary uses. This plant is herbaceous and aromatic and is cultivated in several countries, including India, Italy, the Netherlands, Europe, China, and Bangladesh. The coriander plant is rich in essential oils, vitamins (vitamins C and K), minerals (calcium, phosphorous, potassium, thiamine, and niacin), and other micronutrients. The plants are extensively used in the preparation of food items. C. sativum essential oil and extracts possess various potential pharmacological properties and has been found to possess carminative, diuretic, stomachic, aphrodisiac, anti-inflammatory, antibacterial, antifungal, and anticancer activities. The present study aims to discuss the botany, traditional uses, medicinal, and industrial applications of coriander extracts and essential oils.
ABSTRACT-Guava (Psidium guajava Linn.) is important for its food and nutritional values through out the world of the tropical fruit. The whole plant consists of medicinal properties such as fruit, leaf and other parts of the plant are also used in traditional system of medicine. So that, each part of guava tree contained the economic importance because it is cheap and used in several food dishes and also cultivated on the commercial level. Guava plant is considered to the process of the biological activity and medicinal application of guava so thatthe fruit considered as the poor man apple of tropics. The guava plant parts are used for the treatment of various skin allergy such as patches in your chick, dullness of the face etc. In the investigation, nutritional value of each part of guava fruit and medicinal properties of the fruit, these was obtained from various valuable parts and have been used to provide collective information on its multi purpose applications for human beings.
Sulphur (S) deficiency is widespread in Indian soils, and it has been emerging as a major problem in rice-growing lateritic soils of West Bengal. The vertical distribution of S forms and their relationships with soil physicochemical properties were examined in 50 rice-growing locations of lateritic soils of West Bengal, India, for the current study. For this a total of one hundred fifty representative soil samples were collected from three depths and fifty representative locations of rice-based cropping systems of lateritic belt of West Bengal and analyzed for different fractions of S and important physicochemical properties using standard methodology. Most soils were sandy clay loam to clay loam, with low to medium levels of organic carbon, and strongly acidic to moderately acidic. A decrease in organic carbon across the depths was evident. Among the sulphur forms, organic S was dominant, and the contribution of water-soluble S was least throughout the soil profile. The studied sulphur forms followed the order: total S > organic S > heat soluble S > adsorbed S > sulphate S > water soluble S. Except for adsorbed S, most forms decreased with soil depth. The correlation study revealed that soil pH was positively and significantly correlated with water soluble (r = 0.431**) and sulphate S (r = 0.325*) in surface soils, with sulphate S both in mid-surface (r = 0.450**) and subsurface soils (r = 0.423**). Organic carbon showed a positive correlation with all the S forms throughout the profile. Both clay and silt content positively affected S forms, while sand content showed a negative relationship. Positive correlation among all the S forms observed along soil depth, except for a negative correlation between adsorbed S and sulphate S. This investigation will be helpful for sulphur management to optimize crop yields in lateritic soils.
