    Purpose

    This paper provides an in-depth critical review and analysis of current and recent research undertaken on the agro-ecology, photochemistry, postharvest physiology and utilization of Moringa oleifera Lam.

    Findings

    This treatise provided a comprehensive review of current and relevant research on the horticultural practices, its agro-ecological conditions, and pre- and post-harvest operations and treatments. It showed the alignment of the biochemical production of the various phytochemicals to the ecophysiology of the plant particularly the variety and ecotypes, micro climatic and edaphic conditions, and the crop growth patterns. The detailed aggregation of the different phytochemicals and the sites of synthesis in the plant revealed that the plant produces in excess of 36 phytochemical compounds that manifest its biological efficacy in over 16 different human physiological activity and medicine. Additionally, it revealed the many approaches to the postharvest physiology of the plant parts and the extension of the shelf life and quality for processing opportunities.

    Research limitations

    There were no significant limitations to the conducting of this exercise as the literature was available and accesses to communicate with authors were easily facilitated by the internet. Directions for future research: This is the only review which collated the findings on the agro-ecology, phytochemistry, postharvest physiology and utilization of Moringa oleifera Lam., and how it is linked to the world of ethno-medicine, and pharmacology. Further research is necessary to determine the efficacy of extracts from all parts of the moringa plant as potential and promising eco-friendly alternatives to common chemicals used as novel food preservatives.

    Grazing management and the balance between domestic animal and rangeland need to complete information about rangeland ecosystems and identification of relation between vegetation and livestock. Thus, this research have been studied on the effect of different utilization intensities on vegetation changes in winter rangelands of Miankaleh. After identifying the utilization units, sampling was done in each area with transect-quadrate and systematicrandom method. Number and size of plot identified by statistical and minimal area method, respectively. Then, canopy cover percentage, Frequency, production and palatability of species was recorded in the plots. At last, data analysis was done with variance analysis and means comparison. The results showed that the Gramineae family had more frequency in different grazing intensities, which shows that the Miankaleh rangelands have high vegetative potential to this family nevertheless changes of grazing intensities and dominant species changes from critical to reference area. Also, the effects of low grazing cause to appearance of Trifolium pratense in reference area.

    The logging of trees like the other processes of utilization will create lots of damages for the residual stands in forest. The identification of the types, severity (amount) of the incurred damages, and factors bringing them about are of paramount importance. The aim of this study is to survey the effect of the diameter of trees logged in the residual stands in the fifth section of Valila series of the Mills plan of saturated timbers in Shirga. At first, 50 trees (20%) were randomly selected from 250 marked trees from the various diametrical classes based on the marked protocol. Then 50 semicircle sample pieces in an area of 1500 square meters were selected, and the quantitative (diameter equall to breast and height), and qualitative (eradicated, cracking of crown and stem, and stem and bark peeling) characteristics were measured and registered before and after their logging. The results showed that the diameter equal to breast of logged trees, except in their eradication, can directly have significant impacts on the extent of stem and crown cracking, damaging of stems and peeling of trees, and the greatest damage was also due to the logging of trees in the diametric class of 80 cm and above it.
