A study on the status and biotic pressure of corridors located in and around Mudumalai Wildlife Sanctuary and Sigur Reserve Forest of Tamil Nadu, Southern India was studied between December 1999 and March 2000. The primary objectives of the study were to assess the quality of these corridors in terms of vegetation structure and intensity of use by endangered animals with special reference to elephants and to quantify the dependence of the villagers on these corridors for fuelwood and cattle grazing. A total of 42 plant species were recorded in an area of 6.8 ha. Among them 57% of tree species was food items of elephants. Anogeissus latifolia, Erythroxylum monogynum, Ziziphus mauritiana and Z. xylopyrus was common species in all corridors. The ground cover was barren in most of the corridors. Grass, herb and weed was found in equal ratio in two corridors. Signs of lopping and wood cutting were found in 27 tree species recorded from all corridors. Among them, 15 species were food plants of elephants. The impact of human activity with reference to the extent of dependence on the corridors by villagers particularly intensity of lopping of trees was 35.3 D/ha. Wood cutting, cattle grazing, removals of cattle dung, electric fence, expansion of agricultural field and human settlements were observed to be a major threat in the five corridors. Elephants intensively used Masinagudi-Singara corridor. The greater attraction of elephants to this corridor is availability of Bamboo and perennial water sources. Followed by Masinagudi-Moyar corridor, which was moderately, used by elephants.

Breeding sites of critically endangered white- rumped vultures (Gyps bengalensis) were studied in the Segur plateau of Nilgiris from August 2011 to August 2012. Both direct survey on foot and questionnaire survey were conducted with local inhabitants in and around the study sites. In total, 68 nests of white-rumped vulture were observed in two different locations namely Jagulikadavu and Siriyur. All the nests were recorded on two woody species namely Terminalia arjuna (66 nest) and Spondias mangifera (2 nest). The nests were recorded at a height of 18-36 mts from the ground level. Nest materials such as twigs, dry leaves, grass, thermocol and even polythene covers were observed.Keywords

The present study effect of different planting density on growth parameters of moringa for leaf production (Moringa oleifera Lam.) was carried out during (Feb-Dec.) 2016 in the vegetable field unit, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar. The treatment consisted of five different planting density viz.,T1 (45×45 cm), T2 (60×60 cm), T3 (75×75 cm), T4 (90×90 cm) and T5 (120×120 cm). Among the five different treatments, the treatment T5 (120×120 cm) recorded highest value for plant height, number of branches, number of leaves and stem girth.Keywords

The present study effect of various drying methods on the quality of moringa leaf powder (Moringa oleifera Lam.) was carried out during (Feb-Dec.) 2016-17 in the post harvest technology lab. Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar. The experiment was laid out in Completely Randomized Block Design with four treatments and five replications. The moringa leaves were dried into powder under four different drying methods viz., T1 (outdoor drying), T2 (indoor drying), T3 (oven drying) and T4 (microwave drying). Among the different treatments T3 (oven drying) recorded high powder yield and also recorded highest value for iron and zinc content. The treatment T2 (indoor drying) recorded high powder yield, besides the same treatment also recorded highest value for beta-carotene and ascorbic acid.Keywords

The present study effect of different planting density on leaf yield and quality in leaf production of moringa (Moringa oleifera Lam.) was carried out during (Feb-Dec.) 2015-16 in the vegetable field unit, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar. The treatment consisted of five different planting density viz., T1 (45×45 cm), T2 (60×60 cm), T3 (75×75 cm), T4 (90×90 cm) and T5 (120×120 cm). Observations on growth and yield characters were recorded at 35 days interval and totally eight harvest were made during the study period. The treatment T5 (120×120 cm) recorded highest value for leaf weight, herbage yield per plant and chlorophyll content.Keywords

The primary goal of this paper is to design and analyse the entire double wishbone suspension system for a commercial vehicle in order to improve the vehicle’s stability and handling. The suspension system has seen tremendous advancement. A commercial vehicle’s suspension system must be long-lasting, light in weight, efficient, and cost-effective. The vehicle must be able to withstand the harsh off-road terrain environment. As a result, it is critical to concentrate on the stress strain analysis study of the lower wishbone arm in order to improve and modify the existing design.Keywords
